MaterialPropertyBlock.SetColor

Description

color型のプロパティを設定します

Adds a property to the block. If a color property with the given name already exists, the old value is replaced.

	// Draws 3 meshes with the same material but with different colors.

	var mesh : Mesh;
	var material : Material;
	private var block : MaterialPropertyBlock;
	
	function Start() 
	{
		block = new MaterialPropertyBlock();
	}

	function Update() {
		
		// red mesh
		block.SetColor("_Color", Color.red);
		Graphics.DrawMesh(mesh, Vector3(0,0,0), Quaternion.identity, material, 0, null, 0, block);

		// green mesh
		block.SetColor("_Color", Color.green);
		Graphics.DrawMesh(mesh, Vector3(5,0,0), Quaternion.identity, material, 0, null, 0, block);

		// blue mesh
		block.SetColor("_Color", Color.blue);
		Graphics.DrawMesh(mesh, Vector3(-5,0,0), Quaternion.identity, material, 0, null, 0, block);
	}

/nameID/ でこの関数を呼び出すほうが高速になります。もし、繰り返し同じ名前のプロパティを追加する場合は、 Shader.PropertyToIDを使用してプロパティ名のユニークIDを取得し、SetColorにIDを渡します。
