how do u make it so you dont have to press a key in the beginning?

when a map is done loading, how do you make it so theres no Press any key to continue? like some maps after loading goes straight into the game

EDIT: also i have another quick question, whats the best sound for a machinegun type ability? the closest one i could find was gyrocopter attack but its seems pretty lame for a machinegun, is there anything better?

As far as i know it depends on the loading screen. The default one goes straight to the game while the campaign ones dont. You can check in the loading screen menu.

As for the machine gun, try the marine.

where is the sound file for the marine? i thought of it but could not find it anywhere? can you tell me where it is located?

the "press any key" cannot be turned off, because only Melee maps go "straight away" and ALL custom maps (non-melee) have to press the key to start...
as for the marine, i can't help you...i never used its sound core for anything :)

Shark, non-melee maps that use the default loading screen go straight into the game once all the players have loaded it.

so where is the sound for the attack of a marine? i cant find it anywhere

It is possible with a non-default loading screen if the text is short. I dunno the limit between press any key and not but I guess it is about 3-4 rows text.

if you were good, you woulda realized that the marine's sound IS the gyrocopter

play the gyrocopter's attack sound multiple times, it sounds exactly like the marines cuz it is
