Unity Experiment: Overlapping Rigid Bodies
Overlapping rigid bodies is one of life’s supreme pleasures. Giggitty.
I placed a bunch of cubes all stacked tightly on a plane (they are all positions at 0 on the Z-axis). Then I duplicated one of the central ones repeatedly. When it runs and the physics starts happening those overlapped ones burst apart, bumping into all the other tightly packed cubes. The rest of the geometry is fixed, only the red-lit cubes can move.
