The following reference guide identifies the language syntax, built in variables, functions, and classes that are used to code your simulations in Tychos. Tychos uses the MathNotepad language. We have included documentation here for some of the helpful functions defined in the MathNotepad language. This is not a complete list of all functions available in MathNotepad, just ones that might be commonly used in Tychos for building scenarios as well as defining goals for those scenarios.

Comments

Comments are statements that you can insert in your code that do not get interpreted and executed by Tychos. To create a comment, you simply indicate a comment by using a hashtag:

# This is a comment.

Variables

To define a variable in Tychos all you need to do is identify a name for the variable. You then type an = sign to assign a value to the variable. The following demonstrates various variable declarations

# Assigns a variable called x the value of 10
x = 10
# Assign a new variable y the value of the x
y = x
# Assign x the value of itself plus 1
x = x + 1

Built-in Scenario Variables

There are a few variables that are built into Tychos. These variables are:

• t — How many seconds has passed since this Scenario was started?

• dt — Time between frames as seconds, e.g. 0.1 is 1/10th of a second.

• frame_count — How many frames have passed? e.g. 1, 2, 3...

• X, Y — These are shortcuts for indexing the first two elements of 2-D matrices, e.g. my_particle.pos[X]

Common Math Operators and Functions

These are some common mathematical operators and functions for performing various calculations.

Mathematical Operators

Tychos uses the following operators to perform basic math calculations:

• + — Addition

• - — Subtraction

• * - Multiplication

• / - Division

• ^ - Exponent

• % - Modulo

Basic Math Functions

You can also use the following basic math functions:

Matrix Functions

The following functions provide operations for matrix calculations.

dot(x, y)

Calculates the dot product of two vectors. The dot product of x = [a1, a2, a3, ..., an] and y = [b1, b2, b3, ..., bn] is defined as:

dot(x, y) = a1 * b1 + a2 * b2 + a3 * b3 + … + an * bn

# Work is the dot product of Force (F) and displacement (r)
F = [2, 2]
r = [3, 3]
# returns 12
Work = dot(F, r)

cross

Calculates the cross product for two vectors in three dimensional space. The cross product of x = [a1, a2, a3]and y = [b1, b2, b3] is defined as:

cross(x, y) = [ a2 * b3 - a3 * b2, a3 * b1 - a1 * b3, a1 * b2 - a2 * b1 ]

If one of the input vectors has a dimension greater than 1, the output vector will be a 1x3 (2-dimensional) matrix.

# Torque is the cross product of Force and moment arm (r)
F = [2, 0, 0]
r = [0, 2, 0]
# returns matrix [0, 0, 4]
cross(F, r)

drawArrow

The drawArrow function draws an arrow and is commonly used to illustrate vectors for a particle. drawArrow should be called in the Calculations editor because it only draws the arrow for the current frame. If you call drawArrow() in the Initial State editor, you will not see anything.

drawArrow(pos=[0,0], size=[1,0], color="black", components=false, thickness=1) -> returns and draws an Arrow object

• pos — coordinates for the starting point of the arrow as an [X,Y] matrix.

drawLine

The drawLine function draws a line and is commonly used to illustrate some connecting member like a string or cable, but could really represent anything you like. drawLine should be called in the Calculations editor because it only draws the line for the current frame. If you call drawLine in the Initial State editor, you will not see anything.

drawLine(pos=[0,0], pos2=[10,0], color="black", thickess=1) -> returns and draws an Line object

• pos — coordinates for the starting point of the line as an [X,Y] matrix.

• pos2 — the coordinates of the end point of the line as an [X,Y] matrix.

• color — Optional HTML color value for the line, e.g. "red" or "#ff0000".

• thickness — Optional stroke value that determines the visual thickness of the line.

Example — The illustration above was drawn using this command:

# Calculations editor
drawLine([0, 0], [20, 20], "purple", 2)  # a line
drawLine([0, 0], [10, 20], "green", 10)  # another line

unit_vector

This function returns a unit vector representation of the given input vector. Its magnitude is 1 and the direction matches the direction of the input vector. This can be useful if you need just the direction of a vector, but not its magnitude.

unit_vector(vec) -> returns a vector of length 1, and in same direction as vec.

• vec - any two dimensional vector as a [X, Y] matrix.

Example:

u = unit_vector([3, 4])  # returns [0.6, 0.8]
magnitude(u)             # returns 1

magnitude

This function returns the scaler magnitude of any given vector. This is helpful when you want to know the length of a vector, for example, if you want the magnitude of a vector, but not its direction.

magnitude(vec) -> returns the scaler magnitude of the vector vec.

• vec - any two dimensional vector as a [X, Y] matrix.

Example:

magnitude([3, 4])             # returns 5

direction

This function returns a scalar angle measurement. This is helpful when you want to know the direction of a vector, like the direction of a velocity vector, or the direction of a force vector. The default return angle is given in radians, but can also be expressed in degrees.

direction(vec, units="rad") -> returns the scaler angle measurement of the vector vec heading in radian form or in degree form.

• vec - any two dimensional vector as a [X, Y] matrix.

• units - optional deg for degree measurement or the default of rad for radians.

Example:

• radius - scalar quantity representing the scalar distance of the radius of the

• angle - scalar quantity representing the angle measurement of the polar coordinate.

• units - optional deg for degree measurement or the default of rad for radians.

Example:

polar(10, 45, "deg")         # returns [7.07, 7.07]
polar(10, PI/4)            # returns [7.07, 7.07]

stop

This function actually evaluates a boolean test and then stops the simulation once the boolean test succeeds. This can be useful if you want the simulation to stop when some condition has been met within your simulation.

stop(test) -> returns a either false or true. If true is returned, the simulation stops.

• test - a boolean statement that can be evaluated to true or false.

Example:

stop(t > 10)             # simulation stops at 10 seconds
stop(buggy.pos[X] == 100) # simulation stops when X position of particle equals 100

Collision Functions

hasCollided

This function returns a boolean true/false value when two Particle objects are given as the source and target. It returns false if the two particles are not determined to be overlapping, meaning that the distance between their positions is less than the sum of their radii.

hasCollided(source, target) -> returns a boolean true or false.

• source - Particle object

• angle - Particle object

Example:

p1 = Particle([0, 0], 10)
p2 = Particle([25, 0], 10)
p3 = Particle([-15, 0], 10)
hasCollided(p1, p2)            # returns false
hasCollided(p1, p3)            # returns true

getIntersect

This function returns a two dimensional matrix representing the minimum translation vector (MTV) that would be needed to separate two Particle objects when they overlap. This can be used to simulate collision forces based on the magnitude and direction of the MTV.

getIntersect(source, target) -> returns a two dimensional matrix.

• source - Particle object

• angle - Particle object

Example:

p1 = Particle([0, 0], 10)
p2 = Particle([25, 0], 10)
p3 = Particle([-15, 0], 10)
getIntersect(p1, p2)            # returns [0, 0]
getIntersect(p1, p3)            # returns [5, 0]

Comparison Functions

The following functions are used to compare two values as being equal or unequal as well as testing if one value is larger or smaller than another. These are very helpful when writing goals for students.

equal(a, b) or a == b

The function tests if two values (x and y) are equal. It returns a boolean value of true or false.

2 + 2 == 3             # returns false
2 + 2 == 4             # returns true
t == 10                # returns true if t is 10, or false if it is not.
equal(2 + 2, 4)        # same as 2 + 2 == 4

deepEqual(a, b)

This function is similar to equal, but it tests element wise whether two matrices are equal. It returns a boolean value of true or false. The code below demonstrates the difference between equal and deepEqual:

p1 = Particle([10, 10])
p2 = Particle([10, 0])
deepEqual(p1.pos, p2.pos)   # returns false
equal(p1.pos, p2.pos)       # returns [true, false]

larger(a, b) or a > b

The function tests if one value (a) is larger than another (b). It returns a boolean value of true or false.

2 > 3               # returns false3 > 2               # returns true2 > 2               # returns falselarger(2, 2)        # same as 2 > 2

smaller(a, b) or a < b

The function tests if one value (a) is smaller than another (b). It returns a boolean value of true or false.

2 < 3                # returns true3 < 2                # returns false2 < 2                # returns falsesmaller(2, 2)        # returns false

unequal(a, b) or a != b

The function tests if two values (a and b) are unequal. It returns a boolean value of true or false.

2 + 2 != 3              # returns trueunequal(2 + 2, 3)       # true -- same as 2 + 2 != 32 + 2 != 4              # returns falset != 10                 # returns false if t is 10, or true if it is not.

Comparison operators return true or false but these also evaluate to 1 (true) or 0 (false). This can allow you to conditionally assign a value to a variable depending on the evaluation of the comparison. See the code below as an example:

# If t is larger than 10, then the value of F is [10, 10], otherwise it is 0.F = (t > 10) * [10, 10]

if(test, true_result, false_result)

The if() function returns true_result or false_result depending on test.

if(true, 3, 44)                 # returns 3if(false, 3, 44)                # returns 44if(1 > 2, 3, 44)                # test is false; therefore returns 44a = 1b = 1if(a == b, "YAY", "darn")       # test is true; therefore returns "YAY"

Logical Operators

The following operators are used to execute logical AND and OR comparisons for the use of evaluating logical statements.

and

This is used for performing a logical AND conjunction. For example, "A and B" is true only if A is true and B is true. "A and B" is false if either A or B is false.

A = trueB = trueA and B # returns trueB = falseA and B # returns false

You can use the and operator to test if two comparisons are both true:

x = 2(x < 3) and (x == 2)  # returns true(x < 3) and (x != 2)  # returns false

or

This is used for performing a logical OR conjunction. For example, "A or B" is true if A or B is true. "A or B" is false only if A and B are both false.

A = trueB = falseA or B # returns trueA = falseA or B # returns false

You can use the or operator to test if one of two comparisons are true:

x = 2smaller(x, 3) or equal(x, 3)    # one is true, so returns true(x < 1) or (x == 3)             # both are false, so returns false

Built-in Classes

Tychos has only a few classes that are used to create the basic simulated objects in the Tychos universe as well as a few tools for analyzing those objects in the simulated world. The two simulated objects in Tychos are the Particleand the Block. The tools that can be used for analyzing the behavior of your simulations are the Graph and the Meter.

Particle

A Particle represents a spherical particle in the simulated world and is drawn as a colored circle in the World View. A particle has position, radius and color.

Particle(pos=[0,0], radius=10, color=default_color) -> returns a Particle

• pos — The inital position of your particle in [X,Y] coordinates. If you don't specify a position, the default value of [0,0] is used.

• radius — The radius of the circle that is drawn in the World View to represent this particle.

• color — The particle will be drawn in this color. Use HTML colors e.g. "#ff3300", "blue".

These attributes may also be modified on the particle after it is created. In particular, one will usually change the pos attribute of a particle in the Calculations editor to show a particle's movement. E.g.

# Initial State editorp = Particle()p_big = Particle([50, 0], 25)p_big.color = "red"p_blue = Particle([100, 0], 10, "green")# Calculations editorp.pos = p.pos + [1, 0.25]

Particle.rotate()

Particle objects can be rotated, but it will have no noticeable affect on the object unless you are using an image as a representation of the Particle.

particle.rotate(angle=0, center_of_rotation=[0, 0]) — Rotates the Particle object by a given angle value in degree units. You can also provide an optional matrix that identifies the center of rotation. This method should only be called from the Calculations code editor.

Particle.addLabel()

Particle objects can also be given a text label. This is similar to the Label object.

particle.addLabel(text="Hello", color="green") — This adds a text label to the Particle object.

Block

Another particle representation in Tychos is the Block. A Block is very similar to a Partcle but it is represented as a colored rectangle in the World View. A block has position, width, height and color. Just as with Particle's, Tychos only uses the width and height attributes for display. You can define how these attributes change given the rules of the simulation that you define.

Block(pos=[0,0], size=[10, 10], color=default_color) -> returns a Block

• pos — The inital position of your block in [X,Y] coordinates. If you don't specify a position, the default value of [0,0] is used.

• size — The width and height of the block that is drawn in the World View to represent the block.

• color — The block will be drawn in this color. Use HTML colors e.g. "#ff3300", "blue".

These attributes may also be modified on the block after it is created. In particular, one will usually change the pos attribute of a block in the Calculations editor to show a block's movement. E.g.

# Initial State editorb1 = Block([0, 0], [10, 10], "green")b2 = Block([20, 0], [10, 20], "blue")b3 = Block([40, 0], [20, 10], "orange")# Calculations editorb1.pos = b1.pos + [1, 0.25]

Block.rotate

You can also rotate a Block object in order to simulate rotational behavior.

Block.rotate(angle=0, center_of_rotation=[0, 0]) — Rotates the Block object by a given angle value in degree units. You can also provide an optional matrix that identifies the center of rotation. This method should only be called from the Calculations code editor.

Example:

# Initial State editorb1 = Block([-20, 0], [20, 10], "green")b2 = Block([0, 0], [20, 10], "blue")b3 = Block([20, 0], [20, 10], "orange")# Calculations editorb1.rotate(rad_to_deg(-PI/4))b2.rotate(90)b3.rotate(45)

Just as with Particle objects, Block objects can also be represented with an image by setting the image attribute of the object. The text must be a URI link to a graphic file that can be a PNG, SVG, GIF, or JPEG image.

rocket = Block([0, 0], [10, 10], "purple")rocket.image = "https://upload.wikimedia.org/wikipedia/commons/3/3d/Spacecraft.png"

Block.addLabel()

Block objects can also be given a text label. This is similar to the Label object.

block.addLabel(text="Hello", color="green") — This adds a text label to the Block object.

Spring

You can represent a spring in Tychos using the Spring class. A Spring is a visual representation of a common elastic connector that displays a given number of coils that dynamically change shape once the dimensions of the Spring are changed in the Calculations Pane.

Spring(pos1=[0,0], pos2=[100, 0], color=default_color, coils=5, width=10, thickness=1) -> returns a Spring object

• pos1 — The position of one end of the Spring. If you don't specify a position, the default value of [0,0] is used.

• pos2 — The position of one other end of the Spring. If you don't specify a position, the default value of [100,0] is used.

• color — The block will be drawn in this color. Use HTML colors e.g. "#ff3300", "blue".

• coils — This is the number of coils represented.

• width — This is the width of the coils.

• thickness — This is the stroke weight of the coils.

The code below shows the three different Spring objects above that have different lengths, widths and coil numbers. The Particle objects are shown just for reference.

# Initial State editorp = Particle([0, 0], 2, "green")spring = Spring([0, 20], [0, 0], "black", 20, 2)p = Particle([10, 0], 2, "green")spring = Spring([10, 20], [10, 0], "black", 10, 4)p = Particle([20, 0], 2, "green")spring = Spring([20, 20], [20, 0], "black", 20, 2)

These attributes may also be modified after the Spring is created. In particular, one will usually change the pos2 attribute of a Spring in the Calculations editor to show Spring's movement or deformation.

Label

You can add text labels to any scenario using the Label class. A Label has position, width, height and color, similar to a Block, but also has a text value. Just like all Tychos objects, you can define how these attributes change in the simulation.

Label(pos=[0,0], size=[10, 10], text="Hello", color=default_color) -> returns a Label object.

• pos — The inital position of your block in [X,Y] coordinates. If you don't specify a position, the default value of [0,0] is used.

• size — The width and height of the block that is drawn in the World View to represent the block.

• text - The actual text value of the label.

• color — The block will be drawn in this color. Use HTML colors e.g. "#ff3300", "blue".

These attributes may also be modified after the Label object is created. Here is an example of how to make several Label objects:

# Initial State editorlabel1 = Label([0, 100], [50, 50], "Cat", "green")label2 = Label([0, 0], [150, 150], "Dog", "red")label3 = Label([0, -100], [50, 50], "Mouse", "blue")

Label.rotate

Just as with a Block object or a Particle object, you can rotate a label as shown above:

label3.rotate(PI/4)

Interface Widgets

Tychos also provides several widgets for displaying data in different ways as well as adding user interactivity so that your simulations can respond to input.

Graph

A Graph is a 2-dimensional chart of data that you specify in the Calculations editor. Each Graph that is created will appear on the right side of the World View. Your program needs to add points to the graph with the plotcommand.

Graph(title="Untitled", y_axis="Y", x_axis="X") -> Returns a Graph

• title = Optional text that will appear at the top of the graph.

• y_axis = Optional text that will appear on the left side of the graph as the vertical axis label.

• x_axis = Optional text that will appear at the bottom of the graph as the horizontal axis label.

graph_x_t = Graph("X Position vs Time", "X Position", "Time")
graph_vx_t = Graph("$v_x$", "Velocity", "Time")
graph_ax_t = Graph("$a_x", "Acceleration", "Time")

Graph.plot

graph.plot(x, y, color=default_color) — Adds a data point to your graph.

Example:

# Initial State editorg = Graph("X Positions vs Time")# Calculations editor# Graphing a particle projectile's Y velocityg.plot(t, particle.pos[X], "blue")g.plot(t, particle.pos[Y], "red")

Graph.integrate

graph.integrate(color=default_color) — When you call the plot function of a graph, you create a new plot set. You can then integrate this plot set. This is done by referencing the plot set's color. This returns the calculated area based on the trapezoidal method of approximation.

Example:

# Initial State editorg = Graph("Y Velocity")# Calculations editor# Graphing a particle projectile's Y velocityg.plot(t, particle.v[Y], "green")g.integrate("green")

Meter

A Meter is a numeric display of data that you specify in the Calculations editor. Each Meter that is created will appear on the left side of the World View. Your program needs to tell the Meter what value it needs to display by using the display command.

Meter(title="", color=default_color) -> Returns a Meter

• title = Optional text that will appear at the top of the meter.

Meter.display

meter.display(value, units) — Displays the value on the Meter.

• value = Numeric value to be displayed.

• units = String representing the unit label to be displayed.

Example:

# Initial State editormt = Meter("Time")# Calculations editormt.display(t, "s")

Gauge

A Gauge is an analog display of data that is very similar to a Meter that you specify in the Initial Sate pane. Each Gauge that is created will appear on the left side of the World View. Gauges also need to to be set up with a specific minimum and maximum value for identifying the range of the Gauge. Your program needs to tell the Gauge what value it needs to display by using the display command.

Gauge(title="", max=100, min=100, color="default_color") -> Returns a Gauge

• title = Optional text that will appear at the top of the Gauge.

• max = The maximum value of the Gauge

• min = The minimum value of the Gauge

Gauge.display

gauge.display(value) — Displays the value in the Gauge.

Example:

# Initial State editorg1 = Gauge("Value 1", 200, 0, "orange")g2 = Gauge("Value 2", 100, -100, "purple")g3 = Gauge("Value 3", 100, 0, "blue")# Calculations editorval = 44g1.display(val)g2.display(val)g3.display(val)

Interactivity

The following section describes different user interface elements that can be used to create interactive simulations in Tychos.

Toggle

A Toggle is an interactive widget that allows you associate a boolean value (true or false) with the state of the Toggle widget.

Toggle(title="") -> Returns a Toggle

• title = Optional text that will appear at the top of the Toggle.

Toggle.value

x = toggle.value — Returns the current value of the Toggle. This is read/write.

Example:

Slider

A Slider is an interactive widget that allows you to link a value in your scenario to the current value of a horizontal slider.

Slider(title="", min=0, max=100, step=1) -> Returns a Slider

• title = Optional text that will appear at the top of the Slider.

• min = The minimum value of the Slider

• max = The maximum value of the Slider

• step = The step increment of the Slider

Slider.value

x = slider.value — Returns the current value of the Slider. This is read/write.

Example:

# Initial State editors1 = Slider("I'm A Slider", 0, 100, 2)# Calculations editorx = s1.value

keyboard

The keyboard object represents your computers keyboard and has commands to see if any keys are pressed during a simulation.

keyboard.is_down

keyboard.is_down(key) -> boolean — Return 1/0 whether key is currently down

keyboard.last_pressed

keyboard.last_pressed(key) -> boolean — was key typed? i.e. key was pushed down then released.

mouse

The mouse object represents your computer's mouse.

mouse.pos

mouse.pos -> vec — Returns two dimensional vector as a [X, Y] matrix representing the position of the mouse in the simulation space.

mouse.is_down

mouse.is_down(button_num=0) -> boolean — Returns whether the mouse button is pressed. button_num — Which button to check? 0 = primary button, 1 = secondary, etc.

mouse.is_over

mouse.is_over(object) -> boolean — Returns whether the mouse is positioned over an object that is either a Particle or a Block. object — A simulation object.

Data Output

You can create a representation of variable values, displayed in the Data Output tab, by using various API calls on the built in table object.

table.setColumns

table.setColumns(columns=[]) - You must first define the column headings for the table in the Initial State pane. The arguments are simply an array of string values representing the column headings of the table.

table.addRow

table.addRow(row_data=[]) - Once the table columns have been defined, you then need to define the row data to be added to the table. This is an array of any data type values.

Example:

# Initial State editortable.setColumns(["time", "x value", "y value"])# Calculations editorx = t * 2y = t / 2table.addRow([t, x, y])

The code above would generate this table:
