i'm trying to add dynamic lights to a static light shader, i want to include support for all 8 lights, but how do i do it? i started working on being able to move through each light, but i don't know how to set it to use all of the lights around you:

Code:

---

float4 SpecularIntensity = {2.0f, 2.0f, 2.0f, 2.0f};

// Application fed data:
float4x4 matWorldViewProj;
float4x4 matWorld;
float4x4 matWorldInv;

float4 vecAmbient;
float4 vecLightPos[8];
float4 vecLight[8];
float vecLightColor[8];
float3 vecViewDir;
float3 vecViewPos;

texture entSkin1;
texture entSkin2;

samplerCUBE CubeMapSampler = sampler_state
{
	Texture=<entSkin2>;
};
sampler ColorMapSampler = sampler_state
{
	Texture = <entSkin1>;
	AddressU  = Clamp;
	AddressV  = Clamp;
};

void SpecularCubeVS(in float4 InPos		: POSITION,
				in float3 InNormal	: NORMAL,
				in float2 InTex		: TEXCOORD0,
				
				out float4 OutPos	: POSITION,
				out float2 OutTex	: TEXCOORD0,
				out float3 OutTexCube	: TEXCOORD1,
				out float3 OutNormal: TEXCOORD2,
				out float3 OutViewDir: TEXCOORD3)
{
	OutPos = mul(InPos, matWorldViewProj);

	OutNormal = normalize(mul(InNormal,matWorld));

	OutViewDir = mul(InPos, matWorld);

	OutTex = InTex;

	float3 V = normalize(vecViewDir);
	float3 N = normalize(mul(InNormal, matWorld));
	OutTexCube = reflect(V,N);
}

float number;

float4 SpecularCubePS(	in float2 InTex		: TEXCOORD0,
					in float3 InTexCube : TEXCOORD1,
					in float3 InNormal	: TEXCOORD2,
					in float4 InViewDir	: TEXCOORD3) : COLOR
{
	number = 1;
	InNormal = normalize(InNormal);
	float4 Ambient = vecLight[number];
	
	float4 Diffuse = saturate(dot(vecLightColor[1], InNormal));
	
	float4 texColor = tex2D(ColorMapSampler, InTex);
	float4 cubeColor = texCUBE(CubeMapSampler, InTexCube);
	float4 Color = lerp(texColor, cubeColor, 1 - texColor.a);

	float3 R = normalize(2 * dot(InNormal, vecLightColor[number] + SpecularIntensity) * InNormal - SpecularIntensity);

	InViewDir = vecLightPos[number] + SpecularIntensity *vecLight[number];
	
	float Specular = saturate(dot(R, InViewDir));
	return (Ambient + Diffuse + Specular) * Color;
}

technique SpecularCubeTechnique
{
	pass P0
	{
		AlphaBlendEnable = False;
		ZWriteEnable = True;
		VertexShader = compile vs_2_0 SpecularCubeVS();
		PixelShader  = compile ps_2_0 SpecularCubePS();
	}
}

as you can see i can set it to 1 light, but no more...i can set the number of the light it uses, but that's all...

it only works with 1 light because float number has a value of 1
i think that you need a bucle :

for (number=1; number<=8; number+=1) {}


try thiis :


float number;

float4 SpecularCubePS( in float2 InTex : TEXCOORD0,
in float3 InTexCube : TEXCOORD1,
in float3 InNormal : TEXCOORD2,
in float4 InViewDir : TEXCOORD3) : COLOR
{
number = 1;
InNormal = normalize(InNormal);

//add a bucle im not sure if is number+=1 or number++
for (number=1; number<=8; number++) {

float4 Ambient = vecLight[number];

float4 Diffuse = saturate(dot(vecLightColor[1], InNormal));

float4 texColor = tex2D(ColorMapSampler, InTex);
float4 cubeColor = texCUBE(CubeMapSampler, InTexCube);
float4 Color = lerp(texColor, cubeColor, 1 - texColor.a);

float3 R = normalize(2 * dot(InNormal, vecLightColor[number] + SpecularIntensity) * InNormal - SpecularIntensity);

InViewDir = vecLightPos[number] + SpecularIntensity *vecLight[number];

} //end for

float Specular = saturate(dot(R, InViewDir));
return (Ambient + Diffuse + Specular) * Color;
}
