Need to save the point of unit in region and move to matching point in other region

I have 4 regions which are the exact same width/height. I'm trying to move a unit (or, ALL units, rather) from one region to the other, in their exact same positions using text commands.

Example: So, I have 3 riflemen at the bottom left, 2 footmen at the top, and 1 priest in the middle of region A - I want them all moved to their exact same positions, but in region B instead.

I'm actually trying to do this as I type, I just paused to post as I am having poor luck figuring it out. It may just be that it requires math skills that I don't have, or something ;) Thanks for help in advance!

What you need to do is something like for each unit in region A, calculate (position of unit) - (center of region A) and move unit instantly to (center of region B) + (position of unit) - (center of region A). Note that I don't think JASS lets you directly add positions, so you will need to do that for both the X and Y coordinates and then recombine those to a point.

I think I can see what you mean, but that mostly went over my head. Let me explain what I think you meant (or what I think might work, based from what you said).

For every unit in region A - save their current position as a variable (or 2) representing the 2 offsets ? Let's say from the very center of the region A, for simplicity - offset by X and Y. Then move to center of region B offset by X and Y?

A couple issues I have are getting those positions to a variable. I don't know how to set it properly. Maybe that's exactly what you just said, I don't know hehe. I see there is already a trigger to move to center of region with offset, etc. So the second part should be easy!

You won't even need variables! Just

move (TheUnit) to (Center of (Destination Region) offset by (X of position of TheUnit - X of center of (starting Region)), (Y of position of TheUnit - Y of center of (starting region)))

Edit - Think there's a Math function to calculate the X and Y offset between two points - using that would simplify it even further

You da man Ligature :D That works perfectly, thanks!

I suppose a math function isn't really gonna be needed unless I need to make many variations of this trigger, but as it is it's just a simple "move everything to the other place" trigger.
