Below we have provided some snippets of code you can use by copying into your own Glowscript program, modifying the code, and running the program. Any code with a # in front of it is simply a comment (i.e., an editor's note) that defines what the line will make the computer do. The first line of a Glowscript code must always be…

GlowScript 2.9 VPython

Objects

Here is some code you can use and modify to create objects like blocks and platforms.

#Create a box object
MyBox = box(pos=vector(0,0,0), length=1, height=1, width=1, color=color.red)

Motion

Here is some code you can repurpose to define vectors and variables.

#Define a velocity vector
v = vector(3,0,0)

#Define the time variables (initial time, time-step, final time)
t = 0
dt = 0.01
tf = 2

Here is some code you can repurpose to add animations to your code (notice the indentation of lines below the while line).

#While loop to iterate over time until we reach the final time
while t < tf:

#Rate keeps animation slow enough to view
rate(100)

#Position update step to predict location of box after a time-step dt base on v
MyBox.pos = MyBox.pos + v*dt

#Update the time to go on to the next time-step after the position update
t = t + dt

Graphing

Here is some code you can use to graph physical quantities in real-time with the animation, such as position or kinetic energy.

#Create graph object for position
PositionGraph = gcurve(color=color.red)

#While loop to iterate over time
while t < tf:

#Rate keeps animation slow enough to view
rate(100)

#Position update step to predict location of box after a time-step dt
MyBox.pos = MyBox.pos + v*dt

#Add a data point to our graph for with the position at time t
PositionGraph.plot(t,MyBox.pos.x)

#Update the time to go on to the next time-step after the position update
t = t + dt
