如何在MonoGame中使用着色器? [英] How to use shaders in MonoGame?
问题描述
有人可以告诉我,如何在单人游戏中使用着色器吗?
Can someone tell me, how to use shaders in monogame?
我有此错误: https://gamedev.stackexchange.com/questions/46994/有任何人都能在Windows 8的Monogame中获得-照明引擎的工作原理
我尝试使用2MGFX,但该工具报告:效果必须至少包含一种技术并通过.从myshader.fx文件中可以看到它.
I tried to use 2MGFX, but the tool reports: The effect must contain at least one technique and pass. From what I can see from myshader.fx the file, it does.
这是我的着色器代码:
sampler TextureSampler : register(s0);
float _valueAlpha = 1;
float _valueRGB = 1;
float4 main(float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0
{
// Look up the texture color.
float4 tex = tex2D(TextureSampler, texCoord);
// Convert it to greyscale. The constants 0.3, 0.59, and 0.11 are because
// the human eye is more sensitive to green light, and less to blue.
float greyscale = dot(tex.rgb, float3(0.3, 0.59, 0.11));
// The input color alpha controls saturation level.
tex.rgb = lerp(greyscale, tex.rgb *_valueRGB, color.a *_valueAlpha);
return tex;
}
technique Technique1
{
pass Pass1
{
PixelShader = compile ps_3_0 main();
}
}
我尝试将技术更改为Technique
,并将通行证更改为Pass
,但仍然抛出"效果必须包含至少一种技术并通过"
I tried changing the technique to Technique
, and the pass to Pass
, but it still throws "The effect must contain at least one technique and pass"
推荐答案
我成功了! :)
首先,我使用了2MGFX工具.然后我加载了这样的效果:
First of all I used 2MGFX tool. Then I loaded the effect like this:
BinaryReader Reader = new BinaryReader(File.Open(@"Content\\myShader.mgfxo", FileMode.Open));
myShader = new Effect(GraphicsDevice, Reader.ReadBytes((int)Reader.BaseStream.Length));
希望它也会对其他人有帮助! :)
