Need help with creating "Bomb Spots" with the map editor...

[cokacola]

Hey guys, I need someone who can point me in the right direction, the direction I need to go to achieve this:

What I am trying to do, is add a custom "item" to the map editor, to spawn what I will call Bomb Spots.

Then, when I can place them, I need to be able to access them using a lua script(they will be in a saved map, of course)

After I access them, I am going to need to create a function, that when executed, will shoot 1 missile down to each of these "Bomb Spots".

I think I can create the missile, but the main problem will be creating the Map Editor Definition, and loading the coords with LUA.

To whom can help me, I say thank you
