UAnimInstance::AppendAnimationCurveList

function Engine Since 4.19

#include "Animation/AnimInstance.h"

Access: public Specifiers: const

Description

Appends the current curve values matching the given curve type into the caller-supplied map, adding to whatever entries already exist.

Caveats & Gotchas

• Appends rather than replaces — call on a freshly cleared map if you don't want values from a previous call mixed in.
• Replaced the deprecated GetAnimationCurveList(Type, OutMap) overload; prefer this function when accumulating curves from multiple sources.

Signature

void AppendAnimationCurveList(EAnimCurveType Type, TMap<FName, float>& InOutCurveList) const

Parameters

Name	Type	Description	Default
Type	EAnimCurveType	Which curve flag category to append (e.g. material, morph target).	—
InOutCurveList	TMap<FName, float>&	Map that curve name/value pairs of the requested type are added into.	—

Return Type

void

Example

Collect all material curves C++

TMap<FName, float> MaterialCurves;
AnimInstance->AppendAnimationCurveList(EAnimCurveType::MaterialCurve, MaterialCurves);
for (const TPair<FName, float>& Pair : MaterialCurves)
{
    UE_LOG(LogTemp, Log, TEXT("%s = %f"), *Pair.Key.ToString(), Pair.Value);
}
