Description
Returns A minus B as a new FIntPoint, computed component-wise. Commonly used to compute the integer displacement between two grid positions.
Caveats & Gotchas
- • Integer underflow wraps silently — if A.X - B.X goes below INT_MIN the result wraps around to a large positive value.
- • The result is a signed displacement; to get an unsigned distance, call GetMax() or take the absolute value of each component separately after subtracting.

FIntPoint Example
Compute grid delta between two tiles C++
FIntPoint Target(7, 3);
FIntPoint Origin(2, 5);
FIntPoint Delta = UKismetMathLibrary::Subtract_IntPointIntPoint(Target, Origin);
// Delta == (5, -2)Tags
