How to Make a Wire Holographic With GMod

Load "GMod" with the Wire Mod add-on installed in your game directory, located on your main hard drive in the "Program Files" folder.

Enter a game, either private or public, and open the creation menu by pressing "Q."

Select the Holo Emitter tool from the Wire Mod tab, changing the color and thickness of the laser. Press the primary fire button, default left mouse button, to apply a Holograph Emitter button on the game map.

Open the creation menu and select a Wire Button from the Wire Mod tab. In the properties of the button, set the sliding bar for Value On to 1.0 and the value for the Value Off slider to zero. Place the button down near the Holograph Emitter.

Create another button, setting its Value On Slider to 1.0 and its Value Off slider to 1,000. Place the second button down near the emitter.

Select the Value tool from the Wire Mode tab, setting its top slider bar to 1. Place a constant value emitter down near the Holograph Emitter.

Select the Wire tool from the Wire Mode tab, use the primary fire of the tool to connect the Holograph Emitter to each of the two buttons.

Use the Wire tool to connect the constant value emitter to the button from Step 4. Select the Random Chip tool from the Wire Mod tab and place three down near the constant value emitter. Connect them to the constant value emitter with the Wire tool gun.

Press the first button to turn the Holographic Emitter on. The second button can be pressed to make the light from the emitter linger.
