 which is called on the node's material resource. With a Sprite2D node, the
 following code can be used to set the ``blue`` uniform.

   var blue_value = 1.0
   material.set_shader_parameter("blue", blue_value)

 Note that the name of the uniform is a string. The string must match exactly
 with how it is written in the shader, including spelling and case.
