The first thing to consider is the prop you’re using. For this effect to work optimally the light prop should have more than one skin. Skins are used in props to change their appearance. Many light props have at least two skins, On and Off.

Skins in more detail.

For this project the HL2 Prop I’m using is models/props_c17/lamp_standard_off01.mdl. There are actually several methods you can use for this effect. For this project I’m using prop_physics for the lamp because we can add outputs to <codee>OnHealthChanged</code>. When the lamp is shot the lights will now go out via our outputs but I’ve also added a bit extra with an env_shooter, which will toss some glass shards.

In the image above you can see:

  1. prop_physics with model models/props_c17/lamp_standard_off01.mdl
  2. env_shooter with model models/Gibs/Glass_shard.mdl
  3. light
  4. light_spot
  5. point_spotlight
