Class TransformDelta

Represents a collection of transform scale changes for procedural animation. Analogous to MaterialDelta but for transform scale instead of material colors.

Combination Semantics: Uses last-write-wins per TransformId. When combining two TransformDeltas, entries from the other delta overwrite existing entries with the same TransformId. This is deterministic given consistent ordering.

Weight Semantics: Weight represents blend strength, not multiplicative contribution. A weight of 0 means "no change" (identity scale preserved), and 1 means "full delta applied". The applier is responsible for lerping between identity and delta scale based on weight.

Syntax

public class TransformDelta

Constructors

TransformDelta()

Creates an empty TransformDelta with no entries.

Declaration

public TransformDelta()

Properties

Count

Gets the number of entries in this delta.

Declaration

public int Count { get; }

Property Value

Type	Description
int

IsEmpty

Checks if this delta has any entries.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
bool

Methods

Clear()

Clears all transform scale entries.

Declaration

public void Clear()

Clone()

Creates a deep copy of this TransformDelta.

Declaration

public TransformDelta Clone()

Returns

Type	Description
TransformDelta	A new TransformDelta with the same entries.

Combine(TransformDelta)

Combines another TransformDelta into this one using last-write-wins semantics. Entries from the other delta overwrite existing entries with the same TransformId.

Declaration

public void Combine(TransformDelta other)

Parameters

Type	Name	Description
TransformDelta	other	The TransformDelta to merge into this one.

GetEntries()

Gets all transform scale entries for applier access.

Declaration

public IReadOnlyDictionary<TransformId, TransformScaleData> GetEntries()

Returns

Type	Description
IReadOnlyDictionary<TransformId, TransformScaleData>	Read-only dictionary of TransformId to TransformScaleData.

MultiplyLocalScale(TransformId, Vector3, float)

Sets the scale multiplier for a transform target with the specified blend weight. If an entry already exists for this TransformId, it is overwritten.

Declaration

public void MultiplyLocalScale(TransformId id, Vector3 scaleMultiplier, float weight = 1)

Parameters

Type	Name	Description
TransformId	id	The transform target identifier.
Vector3	scaleMultiplier	The scale multiplier to apply (1,1,1 = no change).
float	weight	Blend weight (0-1). Default is 1 (full application).

Scale(float)

Scales all internal weights by the given factor. Used for layer blending where the layer itself has a weight.

Declaration

public void Scale(float weight)

Parameters

Type	Name	Description
float	weight	The weight multiplier (0-1).
