Need some help with Village Builder Triggers

my friend found a editable village builder and we're trying to make our own version and most of it is ok so far but we really need to know what is doing what since we have no idea how jass works if anyone can help with having a trigger like:

unit enters region
unit is = to (hero) (the race distinguishable)
remove triggering unit
spawn 2 (race here) builder for owner of triggering unit


when i try to do this it doesnt work cause im using the way some of anime wars like 2 buildings you have a race selector and choose the race and so forth but it wont work and i think i know the income trigger

event: periodic event: evey X secs
Condition: Player owns a (insert unit here)
Action: Give player gold

If anyone can help with the race selectors or the income then please help we really need help

oh and to add more problems the income buildings are all on 1 set cost and i cant change it...

Sorry to pile all of this on just one or 2 people but we really need some help i'll check back later and then again tomarrow

I don't understand what the problem is, you have your triggers written down already, seems like you already have things figured out. You need to post in more detail about where the problem is.

the problem is that when i try and do all of this the race selection doesn't work therefore im still hosting on the old race selection and since i don't know what jass does or how to read it i don't know how to change anything

my problem is i don't know how to convert the hero for two builders

p.s. should i have them all spawn in their own region or should i just give builders no attack?

Perhaps you shouldn't try editing a Jass map then, try getting it to work in your own map without Jass to distract you.
