For game_team_master specify team in team index:
-1 - anyone can activate
1 - only Terrorist can activate
2 - only CT can activate

For game_team_set is now possible to specify a team to change for game_team_master:
-1 - changes team to all
0 - changes team to activator team (default)
1 - changes team to Terrorist
2 - changes team to CT

For specify team you must disable SmartEdit in Valve Hammer Editor and add manualy this:
Key: team, Value: 2 (or other). (see image)

Attention! Do not fix error in Valve Hammer Editor (alt+p):
Entity (game_team_set) has unused keyvalues.

See test map, which shows an example of work. I hope everything is understood.

For help in creating plugin.

[15.09.10 - v0.3]
* Completely changed the code (thanks Arkshine), the function now works as on HL SDK (except for the added new option "team" for the game_team_set entity).
[28.08.10 - v0.2]
* Updated test map.
* Now for specify team for game_team_set you need disable SmartEdit in Valve Hammer Editor and add manualy: Key: team, Value: 2 (or other).
* Now teamindex is work, do not need use Yaw.
* You want to change the field Yaw on teamindex (for game_team_master) or team (for game_team_set). Otherwise Entites stop working on the map.
[27.08.10 - v0.1]
* First release.
