Monogame - Shader parameters missing
- by Layoric
I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter.
I'm not well versed writing shaders, so this might be caused by a more obvious problem.
I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Shader code below
#include "PPVertexShader.fxh"
float2 lightScreenPosition;
float4x4 matVP;
float2 halfPixel;
float SunSize;
texture flare;
sampler2D Scene: register(s0){
AddressU = Clamp;
AddressV = Clamp;
};
sampler Flare = sampler_state
{
Texture = (flare);
AddressU = CLAMP;
AddressV = CLAMP;
};
float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0
{
texCoord -= halfPixel;
// Get the scene
float4 col = 0;
// Find the suns position in the world and map it to the screen space.
float2 coord;
float size = SunSize / 1;
float2 center = lightScreenPosition;
coord = .5 - (texCoord - center) / size * .5;
col += (pow(tex2D(Flare,coord),2) * 1) * 2;
return col * tex2D(Scene,texCoord);
}
technique LightSourceMask
{
pass p0
{
VertexShader = compile vs_4_0 VertexShaderFunction();
PixelShader = compile ps_4_0 LightSourceMaskPS();
}
}
I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue?
As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine.
Any help would be appreciated.
