Beam effects are quite cool, and not to hard to implement.

This is just a short tutorial on how to make lasers using the env_beam entity to create easy-to-do lasers
Step 1: Setting Up Hammer
Pretty simple, just create a simple room and place two brushes that will represent your “laser” tie these two blocks the func_brush and name one block A and block B
Not that hard huh? Finish up and move onto the next step
Step 2: Creating your “Lasers”
Go to your entities list and scroll down to select the env_beam entity, this will control your “laser” place one, does not matter where it is just place one down and go into the properties. Now unlike env_laser the env_beam allows you to choose which entities it starts and finishes from, kind of like how you would make a rope in hammer. But anyway, in properties change the starting entity to A and the ending entity to B. you may also might want to consider changing the life in the properties from 1 to 0, this will make your beam constant.
Also the env_beam is bugged, I do not know why but set the damage/seconds to 0, for some reason with me it starts damaging me when I’m a distance off. So instead were going to create a brush with the nodraw texture over the line that is created between the two entities where the beam starts and finishes and tie it to the trigger_hurt entity. Fiddle with the settings on that, the only important thing to change is the damage type, I changed that to energy beam.
Throw in a light where the beam goes off, spawn and try it out
Step 3: Conclusion
There that wasn’t so difficult now was it? There is infact an env_laser entity but until I or someone else figures that out this will make a good substitute. There are a lot of variables that you can change in the env_beam entity so you can customise it as you wish.
