i need some pointers or help..

i have a hero arena and i have no idea how to make creeps come out of the doors i would be greatful if u helped me also ill give u what ever there called points i forgot what there called but ill give u one

Here's the stuff you'll need:
unit - create units facing angle (to create the creeps)
unit - issue order targeting a point (to move them through the door)
destructible - open/close door (to manipulate the door)

I won't go into specifics yet because: you haven't either, so I can't know what kind of spawning system do you want, at how many gates, when do creeps come, how many, what kind,... and because I'm going to bed now and don't feel like typing the whole creep spawning triggers, because that ain't a small thing.

i can tell you how like every BA it goes like this

Event: Time - Every (x) amount of time

Conditions- NONE

Actions: Destructible- open (w/e gate)
Unit- Create 1 (w/e unit) (keep on doing this until you cover all creeps you want)
Unit- Order (last created unit) to attack-move- to (w/e region) (keep on doing this until you cover all creeps you want)
Wait- (like 10 seconds)
Destructible- close (w/e gate)

Hope this helps

Use a loop instead of a lot of actions,it is simple:
For each integer A do 1 to (number of units) actions
Loop-actions
Create 1 unit
Unit-order last created unit to attack-move to (your region)
Then after the loop, do a wait action and close the door like has been said before.

sucks when about 2/3 of them are protected.. that is the way i am learning the steal skill though.. the other stuff i learn is from people here or just fiddling with stuff other players had on there maps. VERY helpful.. also ideas come from other maps and other people..

if you do that dont forget to put some credit to the people or maps you got stuff from
