shader_set_uniform_matrix


语法:

shader_set_uniform_matrix(handle);


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


Returns:

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.
