Custom lasers
I am currently working on a map where I want to use different colored lasers which only activate the catcher with the same color. To make it even worse: I'd love to combine different colors with some kind of prism.
However, I have no bloody clue where to start =/ so that's where I need some help: how can I get my hands on the scripts of the lasers so I can program my own? Or has someone already built this and can I copy this?
I hope someone can help me

What I mean: I want two lasers, say red and blue, red activates a red laser catcher, blue activates a blue laser catcher.
Blue can't activate the red laser catcher and vise versa.
If the blue and red beam meet at a given point there will be a purple (red+blue) beam that will activate a purple laser catcher.
The point is: I have no idea where to start building custom lasers (which emit blue light for example)

Like in Incredible Machine?
Oh my, Incredible machine was the shiz. And yes I'm guessing they mean that.
Can you change the 'color fx' property in the env_laser and create a filter for the laser catcher?
I could make a different (colored) model, and create a blue emitter, but still the laser won't be blue, so I guess I have to hard code it in an object that I have to create, which is actually a env_portal_laser with another color and another laser color (and probably some filters).
So... Any ideas on how I should start building something like that.
(or at least, how the hell shall I wreck everything apart so I can have access to the sourcecode of the env_portal_laser)

I'd love to see how you did it
Thank You,
