It seems like you are missing a "}" somewhere. try matching all the open and closing ones together and see if all the opening ones have a closing one!!

Yes, you can create a mod with the mod tools, and when you get in the game run the mod. Then you can load up the map and whatever you made in the mod will work on any map

is there a way to get an airstrike or something in my map that kills zombies? if so, can anyone help me with that?

How did you made it?

There is an option in APE that you can select and it will make it revive the player

Maybe try my way? the function it comes from does all the calculations so it might increase the health per round. Also, taking it out of the while loop might make it work if it doesn't work with the loop

Yea, I was afraid that the zombies might have a fixed health this way. Hopefully the riser thing works

This might work (I haven't tested it but it might work. There might be many flaws in it though)

while(1)
{
	zombies = GetAISpeciesArray("axis", "all");
	foreach(zombie in zombies)
/*Idk if you need the zombie there -->*/	zombie zombie_utility::ai_calculate_health(round_number); //change round number to a number
}

then add to the top

#using scripts\shared\ai\zombie_utility;

Nevermind

The Skybox is defined in the lightning state.

What do you mean? I know you can add in another skybox in radiant, and make it lighting state 2. But can you add a skybox to lighting state 2 from the script?

oh ok

I know you can set the lighting state through script, not sure if you can choose which skybox you want from script though

It looks like you are waiting for a player to enter 2 zones at once?

I think in that topic they talked about using the ignoreplayer function or something like that. You could have the zombies ignore the players that are on the vehicle. EDIT: it is the player.ignoreme that they mentioned in the topic

This might help you. you could make it so that while the player is touching a trigger, the zombies go toward a struct.

My best guess is you can't have negative speed (so -25, and -4 aren't possible... I think). I can't test anything now, but you might need to get another path that goes the the opposite way since the original path only goes forward (meaning the nodes are connected the the one in front of it).
