Impulse 2D Physics Engine 1.0.0 remix
★★★ A Rigid Body Physics Engine - oh yeah! ★★★
There are a lot of games around these days that make use of "Rigid body physics engines" (Think Angry birds, Granny smith). I came across a series of articles by Randy Gaul that takes you through the maths for his 'Impulse' Engine and I decided to attempt porting it to Scratch! (Well... someone had to try!). So here is my first cut.
★★★ Useful Keys ★★★
[C] - spawn a Circle.
[R] - spawn a Rectangle.
[Space] - Toggles between Edit & Simulation Mode.
[Mouse] - When simulating this throws balls, when editing, it edits.
[Double Click] - in edit mode to freeze or unfreeze an object.
★★★ Credit ★★★
