Co-Op Door (Portal 2)
Co-Op doors consist of two triggers that both bots step on to open the door and for each trigger a person sign lights up.
Instance
1.) Create a func_instance with the following settings:
Property Name Value Name coop_exit_door VMF Filename instances/coop/coop_team_double_exit_door.vmf
2.) Create a block brush with trigger texture, tie this brush to a trigger_playerteam with the following outputs:
My Output Target Entity Target Input Parameter Delay Only Once 
OnStartTouchBluePlayer coop_exit_door instance:relay_blue_in;Trigger <none> 0.00 No OnEndTouchBluePlayer coop_exit_door instance:relay_blue_out;Trigger <none> 0.00 No OnStartTouchOrangePlayer coop_exit_door instance:relay_orange_in;Trigger <none> 0.00 No OnEndTouchOrangePlayer coop_exit_door instance:relay_orange_out;Trigger <none> 0.00 No
Manual Creation
The Door
1.) Add a prop_testchamber_door. With the following settings:
Property Name Value Name door_01
2.) Add a logic_coop_manager with the following settings:
Property Name Value Name coop_man
and outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnChangeToAllTrue door_01 Open <none> 0.00 No
Triggers
1.) Add a Logic_relay with the following Settings:
Property Name Value Name relay_b_in
and outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger coop_man SetStateATrue <none> 0.00 No
2.) Add a Logic_relay with the following Settings:
Property Name Value Name relay_b_out
and outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger coop_man SetStateAFalse <none> 0.00 No
3.) Repeat steps 1-2 but change the following:
Property Name Value Name relay_o_in
outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger coop_man SetStateBTrue <none> 0.00 No
Add a Logic_relay with the following Settings:
Property Name Value Name relay_o_out
outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger coop_man SetStateBFalse <none> 0.00 No
4.) Create a block brush with trigger texture applied. Tie this brush to a trigger_playerteam with the following outputs:
My Output Target Entity Target Input Parameter Delay Only Once OnStartTouchBluePlayer relay_b_in Trigger <none> 0.00 No OnEndTouchBluePlayer relay_b_out Trigger <none> 0.00 No OnStartTouchOrangePlayer relay_o_in Trigger <none> 0.00 No OnEndTouchOrangePlayer relay_o_out Trigger <none> 0.00 No
Check Boxes
1.) Add a Prop_static with the following settings:
Property Name Value World Model models/props/sign_frame02/sign_frame02.mdl
2.)
Create a 32Lx4Wx32H func_brush with the texture: signage/signage_coop_teamdoor_orange
Property Name Value Name checkbox_o
Align it to the left, inside the frame.
3.) Repeat step 2 but change the following: signage/signage_coop_teamdoor_blue
Align it to the right, inside the frame.
4.)
Add two env_texturetoggle with the following settings:
Property Name Value Name textog_o Target Brush(es). checkbox_o
Property Name Value Name textog_b Target Brush(es). checkbox_b
5.) Add two ambient_generic with the following settings:
Property Name Value Name sound_out Sound Name portal.button_down
Property Name Value Name sound_in Sound Name portal.button_up
6.)
Add the following outputs to relay_o_in:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger textog_o SetTextureIndex 1 0.00 No OnTrigger sound_in PlaySound <none> 0.00 No
Add the following outputs to relay_o_out:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger textog_o SetTextureIndex 0 0.00 No OnTrigger sound_out PlaySound <none> 0.00 No
Add the following outputs to relay_b_in:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger textog_b SetTextureIndex 1 0.00 No OnTrigger sound_in PlaySound <none> 0.00 No
Add the following outputs to relay_b_out:
My Output Target Entity Target Input Parameter Delay Only Once OnTrigger textog_b SetTextureIndex 0 0.00 No OnTrigger sound_out PlaySound <none> 0.00 No
You have now created a door which will open if both co-op partners are in the triggers
