shader_set_uniform_matrix(handle);

参数	描述
handle	The handle of the shader constant to set.

返回：

N/A（无返回值）

描述

With this function you can set the value (or values) of a shader constant to the current transform matrix (as set using the Matrix Functions). You must previously have gotten the "handle" of the constant using the function shader_get_uniform.

注意： All uniforms must be set after calling the function shader_set(), and before calling shader_reset.

重要！该函数在试用版（Trial License）产品中不可用。

例如：

shader_set(shader_Glass);
shader_matrix = shader_get_uniform(shader_glass, "u_vMatrix");
shader_set_uniform_matrix(shader_matrix);
draw_self();
shader_reset();

The above code will get the handle of the shader constant "u_vMatrix" then set that constant to the current transform matrix.
