The title says the problem, but I'll elaborate here.
You purchase the trigger, but sadly it connects everyone to an absolute no matter what distances the players are to the boat. Me and my friend have been trying to figure out a way to get_players then count them and implement them into the if functions to allow all the players to get on ONLY IF they are in distance to the trigger use. Have had no luck in doing so, if anyone can help, it'd be appreciated.

May be impossible but I'm willing to try, I'd like to attach some barbwire to a specific zombie ai types arms and I have no clue how. Information regarding this task will be very helpful, thank you.

The map will be "located" somewhere in Germany, during World War 2 in a separate pocket dimension. The place will be set in a heavily fortified bunker that was once under construction, and now sunken deep into the Earth.

The map will feature 3 different areas that will have some use once it is released.
It will also include cool challenges that will give the map some direction.
The zombies will funnel towards the roof, giving a few vantage points where zombies won't sneak up behind you. The balance I plan on adding for these camping spots will be stronger, unique zombie types.

I am looking for help on creating an airstrike that plays the sound from multiplayer of the shells ripping through the air. The airstrike would be purchasable, activating only outside of the safe area, along with something that allows it to only be activated once per round.

I can't figure out the tutorials on how to edit map files to include a custom gun, say MG6 Magnum, and I've been tinkering with it for a while trying to see what I could do, maybe learn through trial and error like I've been doing but all I did was break my map. I know that the script files are in the iwd's but I'm having trouble on finding out where the scripts are to be placed, and what you need to do have it inside of a random box, etc.

Any help length of help would be appreciated, I've downloaded the mod tools about a week ago and I've really come to enjoy them.
