By changing the Input/Output connections of the basic Team Fortress 2 Entities, a one flag game of Keep-Away can be made.

Required Entities

They will be set up like any regular Capture The Flag map except for several major differences in entity placement and properties.

Starting a keep away map

This is by putting the item_teamflag somewhere in the map that gives equal opportunity to both teams.

Note: In single flag maps the flag is always red, but can be picked up and captured by either team.

Property Name Description Value
Game Type Type of game this flag will be used for. Leave it as "CTF". CTF
Team The team this entity belongs to. Any
Start Disabled Self-explanatory No

Put the team_round_timer entity in the map.

Property Name Description Value
Name Name of the entity. For this example we will use "game_timer" game_timer
Start Disabled Self-explanatory No
Timer length (in seconds) Initial timer length. Set it to something like 600 for now (10 minutes). 600
Setup timer length (in seconds) Setup timer length. (0 = no setup time). Should be 0, because for some reason, the game can't distinguish between the two types of timers in some cases with I/O connections. 0
Reset time on round restart Self-explanatory Yes
Use countdown sounds Self-explanatory Yes
Show timer on HUD Self-explanatory Yes

The timer is now set up. Next on the entity list is game_forcerespawn.

Place the game_forcerespawn entity anywhere in the map. For this example, we will name it "respawn_01".

Now make a brush that preferably fits around the whole map and tie it to the func_capturezone entity. If not the entire map, the brush needs to be wherever any player can go with the flag). Do not hollow this brush! Texture it with either nodraw, or the trigger texture. The trigger texture is preferable due to it being partly transparent in hammer. Use the following properties:

An example
Property Name Description Value
Name Name of the entity. For this example we will use "capzone" capzone
Start Disabled Self-explanatory Yes
Team Self-explanatory Any

Inputs and Outputs

Almost all of this is activated within the team_round_timer because time is what determines the way the game plays out. The way this will work is that when the ten minutes are up, the team holding the flag gains the point.

Go into the team_round_timer properties and click on the Outputs tab at the top of the properties window. Change the Target Entity entries accordingly.

My Output Target Entity Target Input Parameter Delay Only Once
Io11.png On1SecRemain capzone Enable <none> 0.00 No
Io11.png OnFinished respawn_01 Force Respawn <none> 0.00 No
Io11.png OnFinished capzone Disable <none> 0.00 No
Io11.png OnFinished door_red_1 Lock <none> 0.00 No
Io11.png OnFinished door_blue_1 Lock <none> 0.00 No
Io11.png OnFinished game_timer Restart <none> 3.00 No
Io11.png OnFinished door_red_1 Unlock <none> 3.00 No
Io11.png OnFinished door_blue_1 Unlock <none> 3.00 No
Io11.png OnRoundStart capzone Disable <none> 0.00 No

Here are explanations of each of the outputs you have added:

This enables the capture zone when one second remains so that it counts the point just before the round ends.

Now the game needs to force players to respawn so they don't stay outside of their spawn rooms after time runs out. This simulates a round restart.

Now at the same time, tell the capture zone to disable so it doesn't stay on for the next round until time runs out again.

Now assuming the door to the red team spawn room is named "door_red_1", this will lock the door so players can't instantly go for the flag.

Tut5.JPG

Same will be done with the blue door (assuming that it is named "door_blue_1").

Now put in the same stuff, except have the "Via this input" be "Unlock". Enter 3 under "After a delay in seconds of". Do this for both "door_red_1" and "door_blue_1".

Now have the timer restart itself, but after a delay of 3 seconds also. This means, the players will respawn and the timer won't start for another 3 seconds. This gives them some time to get a feeling of how this works and prepare for the round.

Finally, disable the Capture zone so people can't capture as soon as they pick the flag up during the next round. An output like this has been made already, but do this just to be safe in case something else in the map is affecting the timer.

The Finished Product

Now it should work like this:

  • The game starts.
  • Somebody holds the intelligence for ten minutes and gets the point for holding onto it.
  • Everybody respawns and has to wait 3 seconds before the doors open and then the timer starts again.
  • This gets repeated until either team has 3 points total.

Bugs

Known bugs:

  • Occasionally, the intelligence will stay where it is if it is dropped right before the round starts. Then it will be somewhere where it shouldn't be when the round starts over.
  • Also, after the first round, the countdown sounds won't play. So, after the first round, the sounds won't play again.
