Canceling orders

[ILMTitan]

I plan to make it possible to cancel commands in queues given to units coming out of factories. I am also considering making any overlap between buildings cancel, whereas now it cancels if it is within iirc 17*17 of the first build spot.

The first part is clearly positive, but their could be negative aspects for the building canceling (slopes can make it unapparent that certain building would overlap). Should I proceed on both? Should I make a little overlap OK?

could you make the footprint red-colored if it is over another placed building? Kinda like if you try to place a building over an already built one?

Overlapping that doesnt cancel is bad, but cancelling 3 buildings in a square because you accidentaly misplaced the fourth one is bad too.
Either a little overlap is okay or make it impossible to place a blueprint on another, except if they match(within 1 space), which then cancels the blueprint already there

Ok, I'm thinking that if the center of either order is within or on the border of the other order, it will cancel, and further away will simply not build. And, with that system, we do want to cancel all commands that fit the description.

But, we do want to be able to overlap with the queues of other builders, right? Say, if you have two builders with long queues and want the first one done to start some building, you give each a separate build command that is the same. Also, this would be easier to code.

I will have the building footprint show red for the overlap, but turn back green for cancel, because under certain conditions, ie multiple builders selected, the building will be placed when canceling.
