In the previous code I posted the textures would move around when the camera moved. I was using matWorldViewProj instead of matWorld, lol.
I currently have the horizontal surfaces (top and bottom) working like I wanted, but I am messing up the calculations for the vertical surfaces (walls).
float4x4 matWorld;
float4x4 matWorldViewProj;
float4 vecSkill41;
texture entSkin1;
sampler TexSampler = sampler_state
{
Texture = <entSkin1>;
MipFilter = Linear;
AddressU = Wrap;
Addressv = Wrap;
};
struct out_tiling
{
float4 Pos : POSITION;
float2 Tex0 : TEXCOORD0;
};
out_tiling vs_20
(
in float4 inPos : POSITION,
in float3 inNormal : NORMAL,
in float2 inTex0 : TEXCOORD0
)
{
out_tiling Out;
Out.Pos = mul(inPos,matWorld);
Out.Tex0.x = Out.Pos.x + (Out.Pos.y*inNormal.z);
Out.Tex0.y = Out.Pos.z + (Out.Pos.y*inNormal.x);
Out.Pos = mul(inPos,matWorldViewProj);
return Out;
}
float4 ps_20 ( out_tiling In ): COLOR
{
return tex2D ( TexSampler, In.Tex0 );
}
technique TexTile
{
pass one
{
VertexShader = compile vs_2_0 vs_20();
PixelShader = compile ps_2_0 ps_20();
}
}
Any ideas to fix the verticals?
EDIT: Nevermind, I fixed it. The main idea was correct but there was just a dumb mistake I made with the normals.
float4x4 matWorld;
float4x4 matWorldViewProj;
float4 vecSkill41;
texture entSkin1;
sampler TexSampler = sampler_state
{
Texture = <entSkin1>;
MipFilter = Linear;
AddressU = Wrap;
Addressv = Wrap;
};
struct out_tiling
{
float4 Pos : POSITION;
float2 Tex0 : TEXCOORD0;
};
out_tiling vs_20
(
in float4 inPos : POSITION,
in float3 inNormal : NORMAL,
in float2 inTex0 : TEXCOORD0
)
{
out_tiling Out;
Out.Pos = mul(inPos,matWorld);
Out.Tex0.x = Out.Pos.x + (Out.Pos.y*inNormal.x);
Out.Tex0.y = Out.Pos.z + (Out.Pos.y*inNormal.z);
Out.Pos = mul(inPos,matWorldViewProj);
return Out;
}
float4 ps_20 ( out_tiling In ): COLOR
{
return tex2D ( TexSampler, In.Tex0 );
}
technique TexTile
{
pass one
{
VertexShader = compile vs_2_0 vs_20();
PixelShader = compile ps_2_0 ps_20();
}
}
I also leave the fixed code available for anyone interested in somthing like this. (free to use, free to modify, free to re-distribute, no credits needed, no need for permissions, bla bla bla)
