Confiscation Field
This tutorial will show how to create a fully functional confiscation field. A field that will supercharge the Gravity Gun into a much more powerful version of it. If the player also happens to be carrying any other weapons, the field will fizzle them before supercharging the Gravity Gun.

Entity Creation
Step 1
Start off by creating a 512x256x256 room. Keep in mind however, that the room does not have to be this exact size, but the confiscation fields seen in Valve's maps are a similar size to the size of the room that will be created in this tutorial.
Step 2
Create four 128x128 walls on opposite ends of the room. It is recommended that you have them at least 16 units off the ground. Create 4 prop_static entities, and set their World Model to models/props_combine/weaponstripper.mdl. Place them so that each hole has one of these prop_static's flush inside them. Make sure that the holes are sealed in the back as to prevent leaks.
Step 3
Create 4 env_citadel_energy_core entities and place them at the base of each confiscation field emitter. Give them the following keyvalues.
| Property Name | Value |
|---|---|
| Name | weaponstrip_emitterfx |
Then go to the flag's tab and make sure the Start on flag is off and the No small particles flag is on.
Step 4
Create 4 info_target entities and place them in the same place you placed the 4 env_citadel_energy_core's, at the base of each emitter. Give them the following keyvalues.
| Property Name | Value |
|---|---|
| Name | weaponstrip_emitter |
Step 5
Create 4 env_spark entities in exactly the same place as the last two steps. Give them the following keyvalues.

|---|---|
| Name | weaponstrip_emitterspark |

Make sure all flags are unticked.
Step 6
Create 7 ambient_generic entities.

Once that is set up, to simply start the confiscation field, set up a trigger_once to trigger the logic_room0_start_scan relay. As a bonus, you can also add Outputs to logic_room0_start_scan and logic_room0_end_scan to enable and disable Combine Shield Walls respectively.
