Struct ShaderNode 

pub struct ShaderNode {
    pub id: NodeId,
    pub node_type: NodeType,
    pub label: String,
    pub inputs: Vec<Socket>,
    pub outputs: Vec<Socket>,
    pub properties: HashMap<String, ParamValue>,

}

A single node instance in a shader graph.

Fields

id: NodeId

node_type: NodeType

label: String

inputs: Vec<Socket>

outputs: Vec<Socket>

properties: HashMap<String, ParamValue>

Extra per-node properties keyed by name.

editor_x: f32

Position in the editor (for serialization).

editor_y: f32

enabled: bool

Whether this node is enabled. Disabled nodes are skipped during compilation.

conditional_var: Option<String>

Conditional: if set, this node is only active when the named game state variable exceeds the threshold.

conditional_threshold: f32
