attributeValues
The values of each attribute associated with the node’s attached shader.
Declaration
var attributeValues: [String : SKAttributeValue] { get set }Discussion
All nodes have their own copy of an attribute value and therefore the attribute values can be different across the same SKShader. If instead you need all nodes to share the same value, use SKUniform. Uniforms can change values every frame, but uniforms cannot vary per-node like attributes can.
