[Trigger] Forcing building to be built adjacent to another building

[Cayne]

I'm having trouble writing a trigger that forces the player to build certain structures adjacent to another specific structure (similar to addon buildings in starcraft). But I'm not finding any trigger condition that checks for adjacency. The event/action portion is no problem, I just need help getting the trigger to recognize when to cancel construction.

Any help is appreciated.

I don't think theres a way to limit the range of construction, but if you move the constructed structer instantly to the position of the building you want it to be adjacent to, it will automaticly put it in the nearest position to that unit that has enough room for it. do this:

• Events
  • Unit - A unit Finishes construction
• Conditions
• Actions
  • Unit - Move (Constructed structure) instantly to (Position of (Triggering unit))

where triggering unit is just put the building that you want it to be adjacent to. Easiest way to do this is after that building is placed or at the start of the map apply the building to a variable. Then use the variable instead of the specific unit.

hope this helps.

EDIT: read your post wrong, sorry. this condition should do it:

• ((Region centered at (Position of (Triggering unit)) with size (250.00, 250.00)) contains (Constructing structure)) Equal to True

Sorry I'm not entirely clear how that would work. I want certain structures to only be built next to a road specifically.

Why don't you try adding repair and build abilities to the sole building? Buildings can't move, right? That would force the player to build adjecent.

Excuse me, but i have the same problem, If you have played the Map Heroes and Empires, we probably want to make it like that-where the houses and foundations can only be built next to roads- so the building cancels if not build adjacent to the needed structure.

When a building starts constructing, do:

Boolean condition - if Unit Group(units within 256 of "constructed structure" of type "road") is empty then:
Action: cancel constructed structure.

Hmm, the only problem there is that I can't find the action (cancel constructed structure)

then kill it

Well, an alternative could be something like:

• Trigger
• Events
  • Unit - a unit is issued an order targetting a point
• Conditions
  • Order comparison: issued order equal to "farm" // This is the order given when a peasant starts constructing a farm. For other buildings, use other strings
• Actions
  • if Unit Group(units within 256 of "position of order" of type "road") is empty then: order triggering unit to 'stop'
