UBlendSpace::GetClampedAndWrappedBlendInput

function Engine Since 4.0

#include "Animation/BlendSpace.h"

Access: public Specifiers: const

Description

Clamps each axis of a blend input to its configured range, wrapping instead of clamping for any axis marked as wrapping (e.g. a 360-degree direction axis).

Caveats & Gotchas

• Wrapping behaviour depends on the per-axis 'wrap input' setting configured on the blend space asset, not just the numeric range.
• Feed raw/unclamped input here before calling GetSamplesFromBlendInput, otherwise out-of-range values on a non-wrapping axis produce zero-weighted results at the edge.

Signature

ENGINE_API FVector GetClampedAndWrappedBlendInput(const FVector& BlendInput) const;

Parameters

Name	Type	Description	Default
BlendInput	const FVector&	Raw blend input coordinates to normalize against this blend space's axis ranges.	—

Return Type

FVector

Example

Normalize input before sampling C++

const FVector Clamped = MyBlendSpace->GetClampedAndWrappedBlendInput(FVector(Speed, Direction, 0.f));
TArray<FBlendSampleData> SampleDataList;
int32 CachedIndex = INDEX_NONE;
MyBlendSpace->GetSamplesFromBlendInput(Clamped, SampleDataList, CachedIndex, true);
