I just made my map is Sapien, I put in some custom vehicle tags(for some reason I couldn't change the weapon placements), and compiled it. But when I finally got to playing it, all I saw was ONE Warthog. Please tell me if I'm doing something wrong. The vehicles in the gametype is set to default(all of them are 4). I didn't do anything else in Guerilla, though.

You need to swop the vehicles in globals/globals.
Open globals/globals in guerilla, scoll down to the vehicles section, select from the dropdown menu which vehicle you would like to swop (you can only have 6 vehicle types without scripting)
then click the small ... button and select the .vehicle that you want to use.
When placed in sapien you should check the 8 gametype boxes at the bottom of the properties palate.

Can I use another globals for my map? Without modifying the original one?

No. Globals.globals is the one tag that is always compiled. Before you modify it, you should save a copy, so that you don't have to re-extract another map later, or re-install HEK.

You should backup the original in case you screw the modded one.
But you should learn how to do this.

What happens if I click 'Add'? Can I have 7 vehicle types?

if you do that you will screw up the file.
no you cant add 7 vehicle types without using scripts.

If you want respawning vehicles, you would need a more complicated script.
Ask Me Ks for that >.>
Or use the almighty forum search button

If you have more or less than 6 vehicles, the map will exception upon playing it.
