Building must be within range of another..

[pangahas]

Could someone please help me make a trigger that requires a building to be built within the range of another building.
For example in my map before any building can be built it must be within x range of a road otherwise it won't be created and it won't cost you any resources then a text would appear that informs you that it must be built near a road..thanks in advance trigger tags please..

The first building has to be built next to a road. Change the terrain typed used in this trigger to terrain type of your road. Following building have to be built near some other building. You can change the distances.

Create a variable called Road_Boolean. It should be false initially. You may need to use an array if it's for multiplaying.

Add all buildings you need to conditions.
Add some conditions to the unit group selection, like owner of picked unit equal to owner of triggering unit.

It worked!thanks but how do I do it such that every building I build has to be near a road?

Silly me, I forgot to add the other buildings to the condition, hehe..Problem resolved!+ reputation for you and I will credit you in map when its done..
