Verlet Physics Engine
Verlet Physics Engine - by Hieronumos
This was posted on the gmc by Hieronumos, I take no credit for the engine. The file is .gmk (GM8) and works perfectly in both GM and ENIGMA straight from the tin. The main difference though being that ENIGMA absolutely rapes GM in the fps department.
This engine is mainly all mathematics, thus it really shows the edge in speed that ENIGMA has over GM in terms of computational power. Note also, importantly, that the file could also be made more efficient still in ENIGMA by the use of types but this hasn't even been done.
Right mouse = create walls (click three times in a clockwise movement)
Left mouse = create a constraint between two particles
Middle mouse(scroll) = click it to create a particle with random size
G = grab the closest particle
P = pause (you can still create stuff)
R = restart
