GMS2图形着色器仅在DrawGUI中工作

如何解决GMS2图形着色器仅在DrawGUI中工作

因此，我对着色器非常陌生，并且正在使用GMS2市场上的免费着色器>无论如何，我遇到了与该着色器有关的问题，我想我在着色器中还太陌生，无法对此有所了解。 着色器的代码是：

shd_mosaic.vsh ：

attribute vec3 in_Position;
attribute vec4 in_Colour;
attribute vec2 in_TextureCoord;

varying vec2 v_texcoord;

void main()
{
    gl_Position = gm_Matrices[MATRIX_WORLD_VIEW_PROJECTION] * vec4(in_Position,1.0);
    v_texcoord = in_TextureCoord;
}

shd_mosaic.fsh：

varying vec2 v_texcoord;

uniform float time;
uniform vec2 mouse_pos;
uniform vec2 resolution;
uniform float pixel_amount;

void main()
{ 
    vec2 res = vec2(1.0,resolution.x/resolution.y);
    vec2 size = vec2(res.x/pixel_amount,res.y/pixel_amount);
    vec2 uv = v_texcoord - mod(v_texcoord,size);
    gl_FragColor = texture2D( gm_BaseTexture,uv );
}

然后我还有一个管理着色器的对象obj_controller_mosaic：

创建代码：

draw_set_color(c_white);

uni_time = shader_get_uniform(shd_mosaic,"time");
var_time_var = 0;

uni_mouse_pos = shader_get_uniform(shd_mosaic,"mouse_pos");
var_mouse_pos_x = mouse_x - camera_get_view_x(view_get_camera(view_current));
var_mouse_pos_y = mouse_y - camera_get_view_y(view_get_camera(view_current));

uni_resolution = shader_get_uniform(shd_mosaic,"resolution");
var_resolution_x = room_width //camera_get_view_width(view_get_camera(view_current));
var_resolution_y = room_height //camera_get_view_height(view_get_camera(view_current));

uni_pixel_amount = shader_get_uniform(shd_mosaic,"pixel_amount");
var_pixel_amount = 700.0;

shader_enabled = true;
full_screen_effect = true;

surf = surface_create(camera_get_view_width(view_get_camera(view_current)),camera_get_view_height(view_get_camera(view_current)));
view_set_surface_id(view_get_camera(view_current),surf);

DrawGUI 代码：

var_time_var+=0.04;

var_resolution_x = camera_get_view_width(view_get_camera(view_current));
var_resolution_y = camera_get_view_height(view_get_camera(view_current)); 

if shader_enabled shader_set(shd_mosaic);
    shader_set_uniform_f(uni_time,var_time_var);
    shader_set_uniform_f(uni_mouse_pos,var_mouse_pos_x,var_mouse_pos_y);
    shader_set_uniform_f(uni_resolution,var_resolution_x,var_resolution_y);
    shader_set_uniform_f(uni_pixel_amount,var_pixel_amount);
    if full_screen_effect draw_surface(surf,0);
shader_reset();

好的，现在由于游戏中其他对象的某些问题，我希望DrawGUI代码实际上位于Draw事件中。问题是，当我将代码复制到Draw事件上时，我只是得到了黑屏（当代码在DrawGUI事件中时，它可以正常工作）。我可以做些什么来使此代码在Draw事件而不是DrawGUI中起作用吗？预先感谢您的回答！

解决方法

view_set_surface_id使视图渲染到表面。结果，它不会自动绘制到屏幕上-您必须自己做，就像在Draw GUI中一样。

如果您真的需要在常规绘制事件中绘制视图，则需要第二个视图并在Draw事件中基于view_current进行过滤。
