UKismetMathLibrary::GridSnap_Float
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Snaps a float value to the nearest multiple of GridSize. For example, Location=5.1 and GridSize=10.0 returns 10.0.
Caveats & Gotchas
- • If GridSize is 0, Location is returned unchanged — no divide-by-zero error, but the snap silently does nothing. Guard against GridSize == 0 if it's user-supplied.
- • Precision issues can occur when GridSize is very small (e.g., 0.001) due to floating-point representation — the snap target may not be the exact integer multiple you expect.

Snap a placement position to a 100 UU grid C++
FVector RawHit = HitResult.Location;
FVector Snapped;
Snapped.X = UKismetMathLibrary::GridSnap_Float(RawHit.X, 100.0);
Snapped.Y = UKismetMathLibrary::GridSnap_Float(RawHit.Y, 100.0);
