First I'll try to let it work without shadows, but in the end result, only the texture should have a shadow, the white should not. Following code makes the entity totaly white: float4 fadePS(in float2 texcrd :TEXCOORD0):COLOR
{ return fadeColor; }This code gives the entity texture: float4 fadePS(in float2 texcrd :TEXCOORD0):COLOR
{ return tex2D(colorMap,texcrd); }This code always gives the entity texture, nomatter what I put in for skill41: float vecSkill41;
...
float4 fadePS(in float2 texcrd :TEXCOORD0):COLOR
{ return lerp(tex2D(colorMap,texcrd),fadeColor,vecSkill41); }
...
ent->skill41 = 0.5;If I fill in 0.5f instead of vecSkill41 into the lerp, then I do get the right result; 50% white 50% texture. So theres one missing link between lite-c and the effect. EDIT UPDATE: float vecSkill41 = 0.5f; doesn't work either with the lerp function... I'm rather clueless now

Okay, reading the manual actually does help obj->ent->skill41 = floatv(0.5); Full working code for making texture and white: effect = "
float4x4 matWorldViewProj;
float4 vecSkill41;
float4 fadeColor = {1.0f,1.0f,1.0f,1.0f};
texture entSkin1;
sampler2D colorMap = sampler_state {Texture=<entSkin1>;};
float4 fadePS(in float2 texcrd :TEXCOORD0):COLOR
{
return lerp(tex2D(colorMap,texcrd),fadeColor,vecSkill41.x);
}
technique fade
{
pass p0
{
pixelshader = compile ps_1_1 fadePS();
}
}
";
Now I am only missing the shadows

I don't know how the normal vs passes what to the pixelshader..so i do my own vs...hope you like it now... effect = "
float4x4 matWorldViewProj;
float4 vecSunDir;
float4 vecSkill41;
float4 fadeColor = {1.0f,1.0f,1.0f,1.0f};
texture entSkin1;
sampler2D colorMap = sampler_state {Texture=<entSkin1>;};
void fadeVS( in float4 pos :POSITION,
in float2 tex :TEXCOORD0,
in float3 N :NORMAL,
out float4 oPos :POSITION,
out float2 oTex :TEXCOORD0,
out float shade :TEXCOORD1)
{
oPos = mul(pos,matWorldViewProj);
oTex = tex;
shade = saturate(dot(N,-vecSunDir));
}
float4 fadePS( in float2 texcrd :TEXCOORD0,
in float shade :TEXCOORD1):COLOR
{
return lerp(tex2D(colorMap,texcrd),fadeColor,vecSkill41.x)*shade;
}
technique fade
{
pass p0
{
vertexshader = compile vs_1_0 fadeVS();
pixelshader = compile ps_1_0 fadePS();
}
}
";

Got it totaly working just one more issue. When I remove the shadows from the entity using the diffuse, ambient, specular and emissive settings in MED, the shader adds the shadow again. Could 'shade' be multiplied by those current settings (just entity.ambient or entity.diffuse will do) so that the shadow is on when the model actually has a shadow already, and off when it does not? I can't find out how to gain the ambient value from the entity.

I couldn't figure out, vecAmbient seems to be not affected by the settings in MED. I decided to leave it without shadows, the difference is not very noticeable. Thanx bunches for the help Scorpion Here is the result: http://www.youtube.com/watch?v=CJfOc6T7R4YFor everyone wanting to have a flash-my-entity script (thanx to scorpion of course :D):
MATERIAL* flash_effect = {
effect = "
float4 vecSkill41;
float4 fadeColor = {1.0f,1.0f,1.0f,1.0f};
texture entSkin1;
sampler2D colorMap = sampler_state {Texture=<entSkin1>;};
float4 fadePS( in float2 texcrd :TEXCOORD0):COLOR
{
return lerp(tex2D(colorMap,texcrd),fadeColor,vecSkill41.x);
}
technique fade
{
pass p0
{
pixelshader = compile ps_1_0 fadePS();
}
}
";
}
void flash(ENTITY* ent) {
ent->material = flash_effect;
var i = 10;
while (i > 0) {
ent->skill41 = floatv(i/10);
i -= time_step;
wait(1);
}
}
