Hero defend map help please?

[:1]Hi, im new to this kind a' stuff.

I've played many hero defence maps.. but now i want to create my own. I have searched at google but i didnt have

that luck as i want. Now i ask YOU for help. Can you explain or give me guides or any description/information about

hero defence editing? I really want to do this because i got so many ideas.

My idea is:

1. Select hero (20 different heroes)

2. Spawn at a "town".

3. Kill waves of computer units.

4. Buy life books and stuff like that or a helper.

5. The waves grow stronger every time.

6. Learn hero skills by points (start point 1 so you can pick the first attack)

7. I want 3 Users to fight against 1 comp

Please, PLEASE help me out |||The best way to learn how to make specific type(s) of map is to find an unprotected version of the map, then opening it up in worldedit to see it yourself, and understand the inner works of such maps.

Probably hiveworkshop.com(former wc3sear.ch IIRC) has more unprotected hero defense maps than this one, since you get higher rating/review score if you post unprotected map on that site, because that site encourages sharing of mapping techniques.|||The idea it's self has been done a lot. Try to add at least one thing original in that list, that is if you are able and good enough to start creating a kick ass map.

For example, you could have four players, TwoVsTwo, each team defending against a computer. As the game goes on, the heroes keep switching teams randomly. That's just an example.
