Just wanna know is there a way to make people read brief, I mean is there a way to lock the start button until the briefing is ended because for my map players need to get introduced by the storyline [campaign like] so please someone give me the trigger... Thank you

You cant stop people from pressing the start button, sorry.
you can tell them its important, if you dont read it you wont know what to do and you would get farked up and get destroyed in matter of seconds.
When you host your map when it is finished just don't press the start button and tell everyone to read it. Then if anybody else wants to play it and they host it, they will make sure noobs read the briefings because then they will know it is entirely necessary for those who do not know how to play. The game won't start until every player has pressed the start button or the last trigger (if its desplay for...x seconds) runs out of time.
They can press the start botton right away. Sometimes even the mission breifing does not even showup and it just goes right into the game.
its impossible to stop the start button.
[SOLVED]
