UKismetMathLibrary::IsPointInBox
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Determines whether a point lies inside an axis-aligned box, defined by its center and half-extents. Points exactly on the box surface count as inside.
Caveats & Gotchas
- • BoxExtent is a half-size (distance from origin to a face), not the full box dimensions — passing the full size will make the box appear twice as large as intended.
- • The test is axis-aligned in whatever space Point and BoxOrigin are already expressed in; if one is in world space and the other in local space the result is meaningless.
- • Use IsPointInBox_Box if you already have an FBox, and IsPointInBoxWithTransform if the box can be rotated.
Signature
static bool IsPointInBox(FVector Point, FVector BoxOrigin, FVector BoxExtent)Parameters
| Name | Type | Description | Default |
|---|---|---|---|

Return Type
bool Example
Check if an actor is inside a trigger volume bounds C++
FVector BoxOrigin = TriggerActor->GetActorLocation();
FVector BoxExtent = FVector(200.f, 200.f, 100.f);
bool bInside = UKismetMathLibrary::IsPointInBox(TargetActor->GetActorLocation(), BoxOrigin, BoxExtent);Tags
