Maths & trigonometry cheat sheet for 2D & 3D games

Conventions

  • A = [xA, yA] is a point on the 2D plane. Same for B, C, ...
  • lengths are in any unit (ex: pixels)
  • code snippets are in JavaScript

Degrees to radians

angleRad = angleDeg * Math.PI / 180;

Normally if you zip a .app directory on Windows and unzip it on Mac OS X, it won't run. This tool creates a zip file that should have the correct executable flags set to work correctly.
#!/usr/bin/env python3
import os
import sys
import time
import zipfile
startingdir = os.getcwd()
if (len(sys.argv) == 1):
print("Usage: " + os.path.basename(sys.argv[0]) + " path/to/application.app [path/to/output.zip]")
