struct BlendTreeSourceNode

A blend node that contains an animation. This structure adopts ``BlendTreeNode`` and adds the ability to store a single animation. A complete ``BlendTreeAnimation`` represents a mix of all the animations that its source nodes contain. Each source node defines a ``BlendTreeSourceNode/weight`` that determines how much effect the source's animation has in the blend tree's resulting, mixed animation. To define the source's animation, set this structure's ``BlendTreeSourceNode/source`` property. ### Access a source node of a blend tree A source may exist in any leaf-node position in the blend animation's tree. The following code checks the root node for a source. If instead the root node is a branch, the code begins checking the branches sources. ```swift // Check if the root node is a source. if let blendNode = blendTree.root as? BlendTreeSourceNode { // Found a source. // Check if the root node is a branch. } else if let source = blendTree.root as? BlendTreeBlendNode { // Check for a source in the branch's sources. if let source = blendNode.sources[0] as? BlendTreeSourceNode { // Found a source. } } } ```
