This tutorial will walk you through the basics of adding a laser beam with relays and a catcher to your Portal 2 map.

Todo: Add pictures

Note:This tutorial is currently using an alternate method to create Portal 2 maps. Some entities must be manually written in Hammer. This will most likely need updated once the official SDK is released.

Creating the beam

First you'll need to create the base for the laser. If you're attaching the laser to the wall, you'll need a 64 x 64 x 32 space in the wall.

Then create a new entity named env_portal_laser and create the following keyvalues:

Key	Value
StartState	0
angles	0 90 0
skin	0
AutoAimEnabled	1
model	models/props/laser_emitter_center.mdl
drawinfastreflection	0
LethalDamage	0

Note:These were the default values as found in Portal 2's official map sp_a2_column_blocker. The only value you need to worry about changing is angles.

Using Hammer's handles (the X marks you see that shows the center of a brush), line up the new entity inside your hole. Make sure the laser is pointing in the direction you'd like it to.

Creating the relay

This also requires a 64 x 64 x 32 hole.

Create a new entity and name it prop_laser_relay with the following keyvalues:

Key	Value
angles	0 0 0
model	models/props/laser_receptacle.mdl
targetname	name of the catcher (required for logic entities)
vscripts	laser_target/musical_laser_catcher.nut

Note:Once again, these are the defaults taken from the Portal 2 map as mentioned above. Feel free to play with the values. With an angle of 0 0 0, the laser relay will be placed facing up.

As done before, line up the entity with Hammer handles, but raise it so it will be lined up with the real floor surface.

Creating the catcher

Once again, create the standard 64 x 64 x 32 hole in your wall.

Create a new entity and name it prop_laser_catcher with the following keyvalues:

Key	Value
angles	0 0 0
model	models/props/laser_catcher_center.mdl
skin	0
