Creating a Portal Radio

← Portal Level Creation

This tutorial will show you how to create the Portal radios that usually play the fast instrumental version of the Still Alive song.

Construction

1. Create a prop_physics_override entity and set its World Model keyvalue to radio_reference.mdl. Place it where you want in your map.
2. Name the radio radio_1.
3. Create an ambient_generic entity and place it near the radio. Name it radio_sound_1.
4. Make the radio_sound_1's Sound Name Portal.room1_Radio. Make its Source Entity Name radio_1.
5. Make sure none of radio_sound_1's flags are checked.

The radio is now complete!

If you are using fizzler on your map, then:

1. Create an ambient_generic entity and place it inside the fizzler. Name it radio_sound_fizzle
2. Make the radio_sound_fizzle's Sound Name UpdateItem.Fizzle.
3. Create a filter_activator_name. Name it radio_filter. Set Filter Name to radio_1.
4. Create a trigger_once with the same size and same position as the trigger_portal_cleanser, set the filter to radio_filter and set the following outputs:

	Output named	Target entities	Via this input	Parameter	Delay
	OnStartTouch	radio_sound_1	StopSound		0.00
	OnStartTouch	radio_sound_fizzle	PlaySound		0.00
