In GDScript it’s 'node.material.set_shader_param("parameter", value)' so i figured it’s Node.Material.SetShaderParam("parameter",value) in C# but VSCode complains that ‘Material’ lacks a definition for ‘SetShaderParam’ and i can’t find anything in the documentation.

(Material as ShaderMaterial).SetShaderParam("parameter", value)

Little late though.

Here is the Godot 4 version:

var direction = 1;
var material = GetNode(“Icon”).Material;
((ShaderMaterial)material).SetShaderParameter(“direction”, direction);
GetNode(“AnimationPlayer”).Play(“Explosion”);
