hallo

i had a waterfall using my.u*time; but now i donwloaded 6.60 the waterfall doesnt work any more

some were i read it has been changed to fx_uvspeed but i dont know ow this work

//The undocumented texture shifting by u,v parameters and by material scale parameters was discontinued for models (it still works for sprites). For texture shifting apply the fx_uvspeed action from the mtlFX template, which is faster and easier to use than u,v parameters. The uv shifting effect also works with the Standard and Extra editions.

thanks for your help

in the templates there is a small code to do it...if you included the template give your model the action fx_uvspeed...if not also include this code to your script:

Code:

---

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

function mtl_uvspeed_render()
{
// using the material matrix:
// u' = u * mtl.matrix11 + v * mtl.matrix21 + mtl.matrix31;
// v' = u * mtl.matrix12 + v * mtl.matrix22 + mtl.matrix32;
	mtl.matrix31 = floatd(my.skill1*total_ticks,256);
	mtl.matrix32 = floatd(my.skill2*total_ticks,256);
}

function mtl_uvspeed_init()
{
// copy standard model material properties
	mtl_copy(mat_model);
	mat_identity(mtl.matrix);
	mtl.event = mtl_uvspeed_render;
	mtl.ENABLE_RENDER = on;
}

MATERIAL mtl_uvspeed =
{
	event = mtl_uvspeed_init;
	effect = "
	matrix matMtl;

	technique uvspeed
	{
		pass one
		{
			TextureTransformFlags[0] = Count2;
			TextureTransform[0] = <matMtl>;
		}
	}
	technique fallback { pass one { } }
	";
}

//action: fx_uvspeed
//title: Texture shifting in u and v direction

action fx_uvspeed()
{
	my.material = mtl_uvspeed;
	if (0 == my.skill1 && 0 == my.skill2) { my.skill2 = -2; }
}

thx

but i am not so good in matariel
i get an error on this line

mtl_copy(mat_model);
thank you

edit: ok i got it... this is the function:

Code:

---

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

PS: i just copied the code from the templates...

thx i am stuppid i did try this before i made this topic but i said i didnt know how materails work en i need to change some things because it now look realy wierd
from the helft of my entity hij is boosting until the and.

thx many time's i hope i learn materials very vast so my games be less ugly;

i addthis my self for working it

MATERIAL* mtl_temp;

its just a small thing but i did get a bounce of errors

thx thx thx

close topic

doesnt work any more i said i used u and v X speed

6.6 version
