| + | * Try running the code, rotating the viewing window, and zooming in and out. | ||
| + | |||
| + | * Try running the code after each of the following steps to observe the change that arises from adding/editing the code. | ||
| + | |||
| + | * **Line 27:** Add code to update the position of the particle based on its velocity. | ||
| + | |||
| + | <code> | ||
| + | particle.pos = particle.pos + particle.velocity*dt | ||
| + | </code> | ||
| + | |||
| + | * **Line 7:** Edit the code to change the particle velocity to 4 in the x-direction. | ||
| + | |||
| + | <code> | ||
| + | particle.velocity = vector(4,0,0) | ||
| + | </code> | ||
| + | |||
| + | * **Line 10:** Edit the code to change the particle acceleration to -1 in the x-direction. | ||
| + | |||
| + | * **Line 30:** Add code to update the velocity of the particle based on its acceleration. //Hint: Try to mimic line 27, but use “velocity” and “acceleration” instead of “pos” and “velocity”, respectively.// | ||
| + | |||
| + | * **Line 22:** Edit the code to get the particle to stop when its velocity is equal to 0. //Hint: Make the while statement depend on// ''particle.velocity.x''. | ||
