Bumbleball

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 to spheres, and behave differently to blue painted cubes, making them unique in this respect.

Download Features

• A normal sphere button specialized for the bumbleballs, not useable with other objects.
  
• the single bumbleball (model and textures)
  
• droppers for bumbleballs, dirty and clean
  
• the .PSD file for custom textures
  
• bumbleball supports up to 16 skins -- 'skin' values 0-15 in Hammer
  

It consists of:

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

Advantages No scripting is required to add a bumbleball to your map; just add one of the included dropper instances, and trigger it with a button.

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.
