I'm not sure how to get it exactly into the corner. I know $RandomEdgeCoord puts units right on the edge of the map, but I don't know how to specify at a corner in that function. There are functions like $ClosestMapEdge and $FarthestMapEdge_OnMap, but again these just put it on the map edge, not necessarily the corner.

I'm thinking you would need to get the X and Y coordinates of each corner spot then do a $MakeCoord for each of those spots, then you can $SpawnUnit at each of those locations using each $MakeCoord output as the coordinate value.

EDIT: Just did some testing myself and yes this does work.

$MakeCoord(1,1); will give a coordinate in the top left corner of the map. As for the other spots, I don't know the exact coordinates for the other corners so you would need to test it out to find them.

Thanks. You get the corners by using a combination of GetX and GetY, and using $GetBoardExtents
