Syntax
struct FAnimNode_AimOffsetLookAt : public FAnimNode_BlendSpacePlayer
Remarks
This node uses a source transform of a socket on the skeletal mesh to automatically calculate Yaw and Pitch directions for a referenced aim offset given a point in the world to look at.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
float | Alpha | Amount of this node to blend into the output pose |
 |
FPoseLink | BasePose | |
 |
bool | bIsLODEnabled | Cached flag to indicate whether LOD threshold is enabled |
 |
FVector | CurrentBlendInput | Cached calculated blend input |
 |
int32 | LODThreshold | Max LOD that this node is allowed to run For example if you have LODThreshold to be 2, it will run until LOD 2 (based on 0 index) when the component LOD becomes 3, it will stop update/evaluate currently transition would be issue and that has to be re-visited |
 |
FVector | LookAtLocation | Location, in world space to look at |
 |
FBoneReference | PivotSocketBoneReference | Cached reference to the pivot socket's bone |
 |
FTransform | PivotSocketLocalTransform | Cached local transform of the pivot socket |
 |
FName | PivotSocketName | Socket or bone to treat as the look at pivot (optional). |
 |
FVector | SocketAxis | Direction in the socket transform to consider the 'forward' or look at axis |
 |
FBoneReference | SocketBoneReference | Cached reference to the source socket's bone |
 |
FTransform | SocketLocalTransform | Cached local transform of the source socket |
 |
FName | SourceSocketName | Socket or bone to treat as the look at source. This will then be pointed at LookAtLocation |

void | CacheBones_AnyThread
(
const FAnimationCacheBonesContext& Context |
Called to cache any bones that this node needs to track (e.g. in a FBoneReference). |
  |
void | Evaluate_AnyThread
(
FPoseContext& Output |
Called to evaluate local-space bones transforms according to the weights set up in Update(). |
  |
void | GatherDebugData
(
FNodeDebugData& DebugData |
Called to gather on-screen debug data. This is called on the game thread. |
   |
int32 | Get the LOD threshold at which this node is enabled. | |
  |
void | Initialize_AnyThread
(
const FAnimationInitializeContext& Context |
Initialize function for setup purposes |
   |
bool | For nodes that need some kind of initialization that is not dependent on node relevancy (i.e. it is insufficient or inefficient to use Initialize_AnyThread), return true here. | |
  |
void | OnInitializeAnimInstance
(
const FAnimInstanceProxy* InProxy, |
Called once, from game thread as the parent anim instance is created |
