Syntax

UCLASS (Within=Skeleton, MinimalAPI, BlueprintType)  
class UBlendProfile :  
    public UObject ,  
    public IInterpolationIndexProvider

Remarks

A blend profile is a set of per-bone scales that can be used in transitions and blend lists to tweak the weights of specific bones. The scales are applied to the normal weight for that bone

Public function void Removes entries with bone references to invalid bones
Public function Const void

FillBoneScalesArray ( TArray< float >& OutBoneBlendProfileFactors,
const FBoneContainer& BoneContainer
)

 Resize and fill an array of floats with the bone factor values.
Public function Const void

FillSkeletonBoneDurationsArray ( TCustomBoneIndexArrayView< float, FSkeletonPoseBoneIndex > OutDurationPerBone,
float Duration,
const USkeleton* TargetSkeleton
)

 Fill an array of floats with the bone duration values. One for each bone in the skeleton pose.
Public function Const void

FillSkeletonBoneDurationsArray ( TCustomBoneIndexArrayView< float, FSkeletonPoseBoneIndex > OutDurationPerBone,
float Duration
)

 Fill an array of floats with the bone duration values. One for each bone in the skeleton pose.
Public function Const float

GetBoneBlendScale ( const FName& InBoneName
)

 Get the set blend scale for the specified bone, will return 1.0f if no entry was found (no scale).
Public function Const float

GetBoneBlendScale ( int32 InBoneIdx
)

 Get the set blend scale for the specified bone, will return 1.0f if no entry was found (no scale)
Public function Virtual Const float Default value of entries. Default values are not saved.
Public function Const const FBlendProfileBoneEntry &

GetEntry ( const int32 InEntryIdx
)

 Get the bone entry by entry index.
Public function Const float

GetEntryBlendScale ( const int32 InEntryIdx
)

 Get the blend scale stored in a specific entry.
Public function Const int32

GetEntryIndex ( const FName& BoneName
)

 Get the index of the entry for the specified bone
Public function Const int32 Get the index of the entry for the specified bone
Public function Const int32

GetEntryIndex ( const int32 InBoneIdx
)

  
Public function Const EBlendProfileMode

GetMode ()

  
Public function Const int32 Get the number of entries in the profile (an entry is any blend scale that isn't 1.0f)
Public function Const bool  
Public function void Ensures the bone names match the skeleton indices by using the bone name as our lookup key.
Public function void

RefreshBoneEntry ( int32 InBoneIndex
)

 Ensures the bone name of the specified entry matches the skeleton index (does nothing if it doesn't exist)
Public function void

RemoveEntry ( int32 InBoneIdx
)

 Removes the entry for the specified bone index (does nothing if it doesn't exist)
Public function void

SetBoneBlendScale ( int32 InBoneIdx,
float InScale,
bool bRecurse,
bool bCreate
)

 Set the blend scale for a specific bone
Public function void

SetBoneBlendScale ( const FName& InBoneName,
float InScale,
bool bRecurse,
bool bCreate
)

 Set the blend scale for a specific bone
Public function void

UpdateBoneWeights ( FBlendSampleData& InOutCurrentData,
const FAlphaBlend& BlendInfo,
float BlendStartAlpha,
float MainWeight,
bool bInverse
)

 Update all the bone weights for some provided FBlendSampleData.

Overridden from UObject

  Type Name Description
Public function Virtual Const bool UObject.
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.

Overridden from IInterpolationIndexProvider

  Type Name Description
Public function Virtual Const int32 Implementation should return the index into the PerBoneBlendData array that would be required when looking up/blending BoneIndex.
Public function Virtual Const int32 IInterpolationIndexProvider.
