Leadwerks animated textures

[nate066]

I see there is a animated texture shader in the shaders folder but how do I get it to work?

 

[shadmar]

it should be named skinning shader instead of animated, it's for boned animation.

Is there a way to do this for like lava/water in a river/waterfall or something where we move the UV mapping to make the texture look like it's moving?

[shadmar]

Yes add to uniforms

 

uniform float currenttime;

 

Then change

 

 //Modulate blend with diffuse map
outcolor *= texture(texture0,ex_texcoords0);

 

to something like :

 

 //Modulate blend with diffuse map
outcolor *= texture(texture0,ex_texcoords0+currenttime/1000);

 

texture will then scroll slowly in U and V if not clamped.

[Rick]

How do we set the value of the currenttime uniform again from the game or is that a special variable that all shaders have access to?

[shadmar]

Its an engine uniform. So it always updated by the engine. No need to set it.

Is there a way to use a folder with a image sequence inside to animate the the texture on the model. It would be a lot more powerful then just moving the uv's.

[shadmar]

Yeah you can do that in lua, no need to make any special shader.

 

Just load textures 1-20 or whatever number of frames you have in a table in script:start

Then change texture every frame using something like this in update()

 

i=i+Time:GetSpeed()

if i>20 then i=1 end

material:SetTexture(tableoftextures[math.floor(i)])

Thanks Shadmar, I haven't been able to test it out yet but i will post what i do with it.

I'm here because I was searching for information on moving a texture. Actually, my intent was the idea of creating a conveyor belt. But, then I wondered how to implement the motion. I suppose you could set up physics in such a way as to cause the player to slide across the surface at the same speed as the texture... Do any of you have experience with this implementation idea?

 

UPDATE: As an alternative, I could create the belt as a animated model. But, then I have to figure out how to implement the interaction between things and the belt motion???

[gamecreator]

Wouldn't you juse AddForce if the player was standing anywhere on the belt?

[3Dski7059]

I figured it would something like that and sounds like it would be just playing around to get the force and direction correct. Then, I'd just have to figure out if can/should just animate the texture in the FBX.
