UAnimInstance::GetInstanceAssetPlayerLength

function Engine Blueprint Since 4.11

#include "Animation/AnimInstance.h"

Access: public Specifiers: ENGINE_APIUFUNCTIONBlueprintPure

Description

Returns the total length in seconds of the animation asset referenced by the specified asset player node. Used internally by the Blueprint AnimGetter system to expose per-node length data to transition rules.

Caveats & Gotchas

• Marked `BlueprintInternalUseOnly=true` — this function is not intended to be called directly from user Blueprint code. The anim getter system auto-generates one exposed getter node per asset player in the graph; use those nodes instead.
• The index is resolved at compile time by the anim blueprint compiler. Passing an out-of-range index at runtime returns 0.0 without asserting, which can mask errors.

Example

Called internally by AnimGetter — illustrative only C++

// 'Length' getter node that appears in the Blueprint graph per asset player.
float Length = AnimInstance->GetInstanceAssetPlayerLength(AssetPlayerIndex);
