This library will add some simple functions that will always inbound locations to the map. They are simple but may be useful.
JASS:
library BoundUtils initializer SetBoundary
/*
By: Starquizer
To implement it, simply copy the whole contents
of the library then paste it into an empty
converted-to-custom-text trigger.
To use it, use
call GetSpellTargetXBounded() instead of call GetSpellTargetX()
and
call GetSpellTargetYBounded() instead of call GetSpellTargetY()
also you have another two functions
GetBoundedX and GetBoundedY, those will inbound your x and y to the map.
