I am very new to shaders and am currently experementing with the FFP, well thats all I can do as I have a Geforce 2 . I was trying to shift the u/v with this code:

Code:

---

material test_mat

{

	skin2 = mip_bmp;

	effect = "

	        texture entSkin1;

		texture mtlSkin2;

                        technique do_thing

		        {

			   pass P0

			      {

			         Texture[0]=<entSkin1>;

				 AddressU[0] = <mtlSkill1>;

				 AddressV[0] = <mtlSkill2>;

			      }

			}

					";

}





action shader_action

{

	my.material=test_mat;

	while(1)

	{

	   test_mat.skill1+=2*time;

	   test_mat.skill2+=2*time;

	   wait(1);

	}

}



  

---

However I get the error message
error in effect test_mat(11):error X3004: undeclared identifier 'mtlskill1'

Any help would be appreciated. Also does know of any good FFP tutorials for GS?

I'm a shader n00Ob myself, but as far as I know, you have to define "mtlskill1" and "mtlskill2" before, just the way you defined the textures "entSkin1" and "mtlSkin1":
Code:

---

//goes in the line underneath "texture mtlSkin1"

dword mtlSkill1;

dword mtlSkill2;

---

Hope that helped you out a bit

I already tried that but I did dword mtlskill1 instead of dword mtlSkill1. I didnt realise that it was case sensitive. Unfortunatly the texture is not shifting so Im obviously still doing something wrong.

If your using DX9, look at JCL's last post to achieve texture shifting via the material matrix(FFP) -

Texture Shifting Topic

Just apply the "auge_mdl" material to your entity. "mtl.matrix13" shifts the U and "mtl.matrix23" shifts the V.

I've got an error:
nonexistant action mtl_copy;
When I comment out the calling of the function all I get is a black texture

Just put this on the top of everything else. All mtl_copy does is call a function which gives the models the same material settings as mat_model. Here:

Code:

---

 material* mtl1;

function mtl_copy(mtl_source)
{
  mtl1 = mtl_source;
  vec_set(mtl.ambient_blue,mtl1.ambient_blue);
  vec_set(mtl.specular_blue,mtl1.specular_blue);
  vec_set(mtl.diffuse_blue,mtl1.diffuse_blue);
  vec_set(mtl.emissive_blue,mtl1.emissive_blue);
  mtl.power = mtl1.power;
} 

---

Hmm I still get a black texture. However when I comment out the line:
TextureTransformFlags[0] = Count2;
The texture is displayed but with no texture shifting. For some reason does my Geforce 2 not support this shader? I thought it was all fixed-function? That cannot be the case otherwise the fallback would have run.

Please post your complete code up to this point.

Ok:

Code:

---

//function to copy material states
material* mtl1;function mtl_copy(mtl_source){  mtl1 = mtl_source;  vec_set(mtl.ambient_blue,mtl1.ambient_blue);  vec_set(mtl.specular_blue,mtl1.specular_blue);  vec_set(mtl.diffuse_blue,mtl1.diffuse_blue);  vec_set(mtl.emissive_blue,mtl1.emissive_blue);  mtl.power = mtl1.power;} 


action enviro_map
{
	my.ambient+=40;
	my.shadow=on;
	my.material=auge_mdl;
		while(1)
	{
		my.pan+=5*time;
		wait(1);
	}
	
}

}

function mtl_rolleye_1();
function mtl_rolleye_2();
function mtl_eye_init();

//
function mtl_rolleye_2() 
{ 
mtl.skill1 -= time; // shift eyeball right 
if (mtl.skill1 < 0) { mtl.event = mtl_rolleye_1; } 
mtl.matrix13 = floatd(mtl.skill1,500); // u offset 
} 
function mtl_rolleye_1() 
{ 
mtl.skill1 += time; // shift eyeball left 
if (mtl.skill1 > 50) { mtl.event = mtl_rolleye_2; } 
mtl.matrix13 = floatd(mtl.skill1,500); // u offset 
} 

function mtl_eye_init() 
{ 
// copy standard model material properties 
mtl_copy(mat_model); 
mtl.skill2 = 100; // initial texture scale in percent 
mtl.matrix11 = float(1); // default u scale 
mtl.matrix22 = float(1); // default v scale 
mtl.event = mtl_rolleye_1; 
mtl.enable_view = on; 
} 

material auge_mdl 
{ 
event = mtl_eye_init; 
effect = " 
matrix matMtl; 
texture entSkin1;
technique scale 
{ 
// use material transformation matrix, leave everything else at default values 
pass p0 
{ 
Texture[0] = <entSkin1>;
ColorArg1[0] = Texture;
ColorArg2[0] = Current;
TextureTransformFlags[0] = Count2; 
TextureTransform[0] = <matMtl>; 
} 
} 

technique fallback { pass p0 { } } 
"; 
}

Try this:

Code:

---

 


material* mtl1;

function mtl_copy(mtl_source)
{
  mtl1 = mtl_source;
  vec_set(mtl.ambient_blue,mtl1.ambient_blue);
  vec_set(mtl.specular_blue,mtl1.specular_blue);
  vec_set(mtl.diffuse_blue,mtl1.diffuse_blue);
  vec_set(mtl.emissive_blue,mtl1.emissive_blue);
  mtl.power = mtl1.power;
}



// 5-state machine for texture shifting and scaling
function mtl_rolleye_1();

function mtl_rolleye_2()
{
  mtl.skill1 -= time;		// shift eyeball right
  if (mtl.skill1 < 0) { mtl.event = mtl_rolleye_1; }
  mtl.matrix13 = floatd(mtl.skill1,500); // u offset
}
function mtl_rolleye_1()
{
  mtl.skill1 += time;		// shift eyeball left
  if (mtl.skill1 > 50) { mtl.event = mtl_rolleye_2; }
  mtl.matrix13 = floatd(mtl.skill1,500); // u offset
}

function mtl_eye_init()
{
// copy standard model material properties
  mtl_copy(mat_model);
  
  mtl.matrix11 = float(1);	// default u scale
  mtl.matrix22 = float(1);	// default v scale
  mtl.event = mtl_rolleye_1;
  mtl.enable_view = on;
}

material auge_mdl
{
   event = mtl_eye_init;
   effect = "
   matrix matMtl;

   technique scale
   {
// use material transformation matrix, leave everything else at default values
      pass p0
      {
	
	TextureTransformFlags[0] = Count2;
        TextureTransform[0] = <matMtl>;
      }
    }

	technique fallback { pass p0 { } }
  ";
}

action eye { 
my.material = auge_mdl;
	
 }
