Bumbleball

The bumbleball is a new Portal 2 puzzle element created by Skotty and Moth. If the bumbleball is outside of the players view it will bounce around every 2 seconds, making a distinctive sound when bouncing. They're very different from spheres, and behave differently from blue painted cubes, making them unique in this aspect.

Theory

a physics model, with an internal env_shake (this causes it to bounce around by a variable amount)
a env_entity_maker which detects if the player is looking at the ball, and toggles the env_shake

Known Bugs

  • For dissolving a bumbleball (for example in toxic water) you have to FireUser4
  • Paint will colour the bumbleball, but because it's a normal prop_physics, it won't jump or glide. The use of a prop_physics_paintable fixes that problem, but the ball won't be visibly painted.
Note:This may not actually be a bug, because the ball is on spikes raised off the ground, which would possibly explain why paint doesn't affect it.
