For Newbs who want buildable terrain with height limits!

This post is for people who do not know how to build on buildable ground and have levels of height that u cannot build on.

First of all make sure ur building is allowed to be on buildable (obj editing) Then go to your triggers and do the event

Event- Unit starts the construction of a building

Conditions- Constructing unit equal to (your builder)
- Constructing Structure equal to (your structure)
- Terrain height not equal to ( what ever level you want buildable)[this can be found in integers, enviroment]

Actions- Kill constructing structure
- Kill Constructing unit
- Set last killed unit equal to dying unit
- Game message (you cannot build here)
- Create 1 type of constructing unit at postition of dying unit.

There u have it a height restriction as well as building on buildable terrain. I dont know if this will help anyone out though!
