TriggerHitShader

Syntax:

TriggerHitShader fStrength

Used to manually trigger the "hit shader" effect of blurring the screen (normally used when the player is staggered). Commonly used in traps, other "earth shaking" activators, and inebriation effects.

The strength parameter can go up as high as you want, but anything higher than 4 or 5 starts to lose the desired effect.
