This gametype is included in A Boojum Snark's Team Fortress 2 Gametype Library

The complete entity setup for this gametype is included in "A Boojum Snark's Team Fortress 2 Gametype Library," a downloadable VMF that includes all official Team Fortress 2 gametypes. The entities can easily be transferred from the VMF to your own custom map without the hassle of having to build it yourself or debugging it.

This tutorial covers the creation of a dustbowl-style system of rounds.

Step 1 - Outlining

The "outline"

This section will cover the outlines of the linear system.
This tutorial is assuming that you already created the skeleton of your map - which would be the status when the map is nearly completed. The map this tutorial is going to use is a simple, three round map you can see on the picture. It would be vital that you check out the labels on the picture, as everything is written down using those labels.

Step 2 - Control points

The "properties"

This step introduces the usage of the team_control_point_master and team_control_point_round entities.

• Place a team_control_point_master anywhere on your map and go to its properties.

Note:The setup differs from a one-round map, as basically the team_control_point_round entities control the gameplay - much like in a parliamentary democracy: the nation has its own head of the state, but the parliament is governing.

• Set the Switch teams on map win? field to Yes.
• The next step is placing a team_control_point_round entity for each round your map has. The properties of these entities are much like those of the team_control_point_master. Make sure you set an easily identifiable name for each round, such as round_1. The priority field will make sure that the game is linear: Set it to 100 for the first round, 99 for the second round and so on. You may also want to restrict the defending team from winning - set the Restrict team from winning to RED. Finally, in the Control points in this round field, input the Names of the control points for that round, separated by a space.

Note:You may also use the OnWonByTeam1, OnStart and OnWonByTeam2 outputs of the round controls to enable/disable certain entities on the map.

Step 3 - Respawn points

The "playerspawn"

Now that you have your rounds, you might want to specify the entry points of each team.

• Fill your respawn rooms with info_player_teamspawn entities and set their Team key value to any of the teams, it doesn't matter. What might matter is Associated Control Point: if you want the spawn place to be usable by the team who owns a certain control point, then input its name into this field. Important fields are Blue and Red spawn for round. Type the name of the rounds into these fields for which you want a team to spawn at these spawn points.

Step 4 - Timers and rounds

The "time"

The map has almost everything it requires, there is only one little problem: neither teams can win. To set this up, this step explains the creation of a basic timer with additional options.

• Add a team_round_timer entity. Its key values are explained in the table below.

Property Name	Description	Value
Name	Name of the entity	start_timer
Timer Length	Time limit at the beginning (in seconds)	180-300
Max Timer Length	Max amount of time limit (0 = no limit)	0
Setup Timer Length	Setup time before gates open (in seconds)	45-60
Reset Time on Round Restart	Self-explanatory	No
Use Countdown Seconds	Self-explanatory	Yes
Show Timer in Hud	Self-explanatory	Yes

Handling doors

• This entity can open the doors of the attacking team's spawn rooms. To do this, create logic_relay entities, name them in a sequence such as relay_spawn_1, relay_spawn_2 , etc and disable all of them but the first one. Add these outputs to the team_round_timer:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnSetupFinished	relay_spawn_1	Trigger	<none>	0.00	No
	OnSetupFinished	relay_spawn_2	Trigger	<none>	0.00	No

And so on for all of them.

• On each relay, add these outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	!self	Disable	<none>	0.00	No
	OnTrigger	(spawn room door)	Open	<none>	0.00	No
	OnTrigger	(name of next relay)	Enable	<none>	0.00	No

Extending time

• The specified time seems a little short to win 3 rounds, that's why the control points need to be set up for this. For each trigger_capture_area add an output:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnCapTeam2	start_timer	AddTime	(same time limit as beginning)	0.00	No

This will add more time once the capture point is taken.

Step 5 - Team victory

Moving on to address the issue of the teams not being able to win.

Defending team

The "win"

• You need to add a game_round_win entity for this. Set the properties as the following:

Property Name	Value
Name	end_of_game
Team	Red
Force map reset	Yes
Switch teams on map win?	Yes

• Now, go back to the team_round_timer and add an output:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnFinished	end_of_game	RoundWin	<none>	0.00	No

Attacking team

• The issue of BLU not being able to win is a little bit simpler. Add another game_round_win entity with the following properties:

Property Name	Value
Name	blue_win
Team	Blue
Force map reset	Yes
Switch teams on map win?	Yes

• For the very last trigger_capture_area of the very last round, add an output:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnCapTeam2	blue_win	RoundWin	<none>	0.00	No
