Func combine ball spawner

An energy ball pulled from a spawner (to the left). The ball spawners behind the soldiers use the same entity, with different settings.

func_combine_ball_spawner is a brush entity available in Half-Life 2, Portal, and Portal 2. It's a brush that creates and contains prop_combine_balls. See the combine_ball_generator and combine_ballspawner prefabs for examples of uses.

In code, it is represented by theCFuncCombineBallSpawnerclass, defined in theprop_combine_ball.cppfile.

Flags

• 4096: Start Inactive
• 8192: Combine Power Supply

If set, balls will bounce as if in a power generator, like in d3_c17_10b (Overwatch Nexus). If not set, they will behave like balls inside the pillars of light seen frequently in the Citadel.

Keyvalues

How many balls will be bouncing around.

Min ball speed (minspeed) <float>

The minimum speed of balls.

Max ball speed (maxspeed) <float>
