Spinning Siren Lights? Created 17 years ago2007-01-27 00:25:38 UTC by Rory

One of the last effects to my base is like the siren lights when you encounter blast doors in HL1...

How do you get the lights to rotating and spin like (police) siren lights?

All you'd need for the rotating light beam is a func_rotating with a red texture on it and some degree of transparency. You could then use env_renders to turn it on or off (by setting render mode to "Texture" and FX amount to "255"). For the actual light source, you would just use a red colored light entity that you could turn on or off.

How do I do the transparency?

In the properties of the entity, set the render mode to "Texture" and the FX amount to something like 60. I'm not sure exactly what the best number is for this, but 255 will make it fully opaque, so you just go down from there. 90 is usually a good bet for windows, so I figured 60 might be good for this.

if you still dont get it:
