An expression in Godot Shading Language, which will be injected at the start of the graph's matching shader function (vertex, fragment, or light), and thus cannot be used to declare functions, varyings, uniforms, or global constants.
Construct a new instance of VisualShaderNodeExpression. Note: use memnew!VisualShaderNodeExpression instead.
A custom visual shader graph expression written in Godot Shading Language.
Custom Godot Shading Language expression, with a custom amount of input and output ports. The provided code is directly injected into the graph's matching shader function (vertex, fragment, or light), so it cannot be used to declare functions, varyings, uniforms, or global constants. See VisualShaderNodeGlobalExpression for such global definitions.
