Creating a Portal 2 Coop Map

Basic Steps

Here are the basic steps needed to create a coop map:

• Create a func_instance. Set its VMF file to one of the coop spawn rooms, such as <instances/coop/coop_spawn_room.vmf. These VMF files already contain an info_player_start, so don't create another one.
• Create another func_instance, this one set to one of the level end rooms, such as instances/coop/coop_endlevel_room.vmf.
• Build your map in between these rooms. (You can move them, of course.) The embedded VMF files have an obvious exit which should lead into your map. You may need to enclose the rooms in order to prevent leaks.
• Make sure you save the map with the prefix mp_coop_.

That's it! See Testing Portal 2 Co-Op Maps Alone for how to test the map without a partner. (To test it with a partner, both must have the .bsp file. Get into the hub normally, then the host should changelevel to the map.)

Co-op Level Without Spawn Instances

Step 1: Necessary entities

To create a co-op level, you need to use:

• a logic_auto
• TWO logic_relays
• a logic_coop_manager
• TWO logic_scripts
• TWO prop_indicator_panels
• a prop_button
• TWO info_coop_spawns (place them where you want the players to start)

Note:You must hide the prop_indicator_panel and the prop_button so the players won't see it in the level.

Step 2: Names

• Name your first logic_relay "relay_return_hub"
• Name your second logic_relay "@relay_has_new_taunt"
• Name your logic_coop_manager "coopmanage_return_hub"
• Name your first logic_script "script_return_hub"
• Name your second logic_script "@script_mp_coop_lobby"
• Name your first prop_indicator_panel "panel_level_return_orange"
• Name your first prop_indicator_panel "panel_level_return_blue"
• Name your info_coop_spawns "spawns_1"

Note:The prop_button doesn't need a name.

Step 3: Properties

1. Go to script_return_hub's properties and do the following:

Property Name	Value
Name	script_return_hub
Entity Scripts	debug_scripts/mp_coop_transition_list.nut

2. Now go to the @script_mp_coop_lobby's properties and do this:

Property Name	Value
Name	@script_mp_coop_lobby
Entity Scripts	debug_scripts/mp_coop_lobby.nut

3. Continue to the panel_level_return_orange properties:

Property Name	Value
Name	panel_level_return_orange
Time Duration	3
Is a timer?	Yes
Indicator lights	tex_level_return_orange

Warning:panel_return_blue has the same properties except for the "Indicator lights," which is tex_level_return_blue.

4. Continue to the spawns_1s' properties:

Property Name	Value
Name	spawns_1
Team	<red or blue, depending on wich player>

5. Give the prop_button the following properties:

Property Name	Value
Delay Before Reset	3

Step 4: Outputs/Inputs

Now we need to connect all these entities together.

logic_auto Outputs

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnMapSpawn	@script_mp_coop_lobby	RunScriptCode	CheckForNewTaunts()	2.00	No
	OnMapSpawn	script_return_hub	RunScriptCode	MapPostLoaded()	2.00	Yes
	OnMapSpawn	script_return_hub	RunScriptCode	SetMapBranchAndLevel()	0.25	Yes
	OnMapSpawn	spawns_1	SetAsActiveSpawn	<none>	0.00	No

Note:Don't forget the delays and the "Only Once."

logic_coop_manager Outputs

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnChangeToAllTrue	relay_return_hub	Trigger	<none>	0.00	No
	OnChangeToAllTrue	panel_level_return_orange	Check	<none>	0.00	No
	OnChangeToAllTrue	panel_level_return_blue	Check	<none>	0.00	No

• relay_return_hub Outputs

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	script_return_hub	RunScriptCode	ReturnToHubFromLevel()	1.00	Yes

• @relay_has_new_taunt Outputs

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	brush_new_taunts	Enable	<none>	0.00	Yes

• prop_button Outputs

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnButtonReset	panel_level_return_orange	Stop	<none>	0.00	No
	OnButtonReset	coopmanage_return_hub	SetStateBFalse	<none>	0.00	No
	OnPressed	panel_level_return_orange	Start	<none>	0.00	No
	OnPressed	coopmanage_return_hub	SetStateBTrue	<none>	0.00	No

That's it! You now can create co-op maps with working co-op scripting!

Trivia

• When a map is exactly named mp_coop_community_hub.bsp it can be also run with the map command.
