2. Create a 16x16x16 block brush covering the button on the model textured with tools/toolsinvisible. Tie it to a func_button. Under Flags, check Don't move and change the Delay before Reset to however long you want to prevent the player from activating it again.

Note:For doors, make sure you give it enough time for the door to open, stay open and close.

3. Create 3 ambient_generic entities near the switch. Give them the following properties: Property Name Value Name switch_sound_up Sound Name Portal.button_up SourceEntityName switch_model Property Name Value Name switch_sound_down Sound Name Portal.button_down SourceEntityName switch_model Property Name Value Name switch_sound_tick Sound Name Portal.room1_TickTock SourceEntityName switch_model For the switch_sound_tick entity, un-check Starts Silent under Flags. 4. Next create a logic_timer somewhere near the switch. Give it the following properties: Property Name Value Name switch_sound_tickloop Starts Disabled Yes Refire Interval 1 And the following Output: My Output Target Entity Target Input Parameter Delay Only Once Image:Io11.png OnTimer switch_sound_tick PlaySound 0.00 No
