ProjectilePy 0.1.1

Simulate realistic projectile motion!

ProjectilePy

A python library aimed at simulating and solving projectile motion problems. Includes various methods for running accurate numerical discrete-time simulations, both with and without drag.

Features:

• Configurable drag or drag-less simulations for projectiles.
• Real world atmospheric data for improved accuracy with Newtonian drag.
• Itterative root finding methods for calculating firing solutions to targets.
• Easy to use simulator object class, with included examples.

Installation:

You can install the package easily though pip by running the command pip install ProjectilePy

Usage:

There are usage eamples in the src/examples folder, I encourage you to look through them for specific use cases.

1. Create a new intance of the simulator class passing the approapriate arguments to the constructor eg.

   import projectilepy
   mySimulator = projectilepy.model(150,30)
   

2. To run a straightforward simulation invoke the run() method on your simulator object.

   mySimulator.run()
   mySimulator.run(override_angle=40, override_velocity=175) # Instance based overrides
   

3. To examine the results, either invoke the analysis methods (such as final_position or time_of_flight), or directly access the positionValues list for the raw x-y coordiante pairs.

   final_position = mySimulator.final_position()
   time_of_flight = mySimulator.time_of_flight()
   x, y = zip(*mySimulator.positionValues)
   

4. If you have matplotlib installed, you can visualise the trajectory of your projectile using a plot.

   fig, ax = plt.subplots()
   ax.plot(x, y)
   plt.show()
