Textures question

[RiceEatingGuy]

Hey,

is it possible to set different textures for objects with same model id? If yes, please explain me how to do that.

Thanks.

[ALw7sH]

Yes, using shader

[RiceEatingGuy]

Yes, using shader

Thanks. Could you explain to me how to use it or give an example?

[Walid]

All what you need is

dxCreateTexture() 
dxCreateShader() 
dxSetShaderValue() 
engineApplyShaderToWorldTexture()

Well, I tried something... The problem is that it loads just one texture.

client.lua

addCommandHandler("toggle", 
    function() 
        local myShader = dxCreateShader("shader.fx") 
         
        local object1 = createObject (3095, 0.0000, 0.0000, 6.0000, 90.0000, 0.0000, 0.0000) 
        local myTexture1 = dxCreateTexture("texture1.png") 
        dxSetShaderValue(myShader, "Tex0", myTexture1) 
        engineApplyShaderToWorldTexture(myShader, "sam_camo", object1) 
         
        local object2 = createObject (3095, 10.0000, 0.0000, 6.0000, 90.0000, 0.0000, 0.0000) 
        local myTexture2 = dxCreateTexture("texture2.png") 
        dxSetShaderValue(myShader, "Tex0", myTexture2) -- It doesn' t work. It loads myTexture1 
        engineApplyShaderToWorldTexture(myShader, "bonyrd_skin2", object2) 
    end 
)

Hey,

is it possible to set different textures for objects with same model id? If yes, please explain me how to do that.

Thanks.

lua:

local myobject = createObject ( ... 
local myshader = dxCreateShader("effect_file.fx") 
local mytexture = dxCreateTexture("mytexture.png", "dxt5") 
dxSetShaderValue( myshader,"gTexture", mytexture) 
engineApplyShaderToWorldTexture( shader, "texturename", myobject )  

effect:

texture gTexture; 
  
technique TexReplace 
{ 
    pass P0 
    { 
        Texture[0] = gTexture; 
    } 
}

Thanks, but how to apply two different textures to two objects? I get same texture on both objects.

[Ren_712]

I get same texture on both objects.

That means you did not apply the shader to the 'object' element. 'object' can be a vehicle, ped, world object.

For example:

You create 2 objects 2 shaders and 2 textures

dxSetShaderValue( myshader1,"gTexture", mytexture1) 
dxSetShaderValue( myshader2,"gTexture", mytexture2) 
engineApplyShaderToWorldTexture( shader1, "texturename", myobject1 )  
engineApplyShaderToWorldTexture( shader2, "texturename", myobject2 ) 

[Walid]

You don't need to create 2 objects 2 shaders and 2 textures, simply you can use tables.

Example:

Objects = { 
{model =  ,x =  ,y =  , z =  ,rx =  ,ry =  , rz =  ,tex = "Texture name here" }, 
} 
  
for i , v in pairs (Objects) do 
 -- Your code her  
end  

[RiceEatingGuy]

EDIT:

I think I fixed it. Do you see any mistakes or have any advices?

objects = { 
{model = 3095, x = 0.0000, y = 0.0000, z = 6.0000, rx = 90.0000, ry = 0.0000 , rz = 0.0000, tex = "texture1.png", worldtex = "sam_camo"}, 
{model = 3095, x = 10.0000, y = 0.0000, z = 6.0000, rx = 90.0000, ry = 0.0000 , rz = 0.0000, tex = "texture2.png", worldtex = "bonyrd_skin2"} 
} 
  
addCommandHandler("toggle", 
    function() 
        for i, v in pairs (objects) do 
            object = createObject(objects[i].model, objects[i].x, objects[i].y, objects[i].z, objects[i].rx, objects[i].ry, objects[i].rz, false) 
            myShader = dxCreateShader("shader.fx") 
            myTexture = dxCreateTexture(objects[i].tex, "dxt5") 
            dxSetShaderValue(myShader, "gTexture", myTexture) 
            engineApplyShaderToWorldTexture(myShader, objects[i].worldtex, object) 
        end      
    end 
)

Thanks, but I don' t really get it. What' s wrong with createObject script? I tried it in many other ways, but that doesn' t work.

[Walid]

Wrong it should be like this

objects = { 
    {model = 3095, x = 0, y = 0, z = 6, rx = 90, ry = 0 , rz = 0, tex = "texture name here"}, 
    {model = 3095, x = 10, y = 0, z = 6, rx = 90, ry = 0 , rz = 0, tex = "texture name here"} 
} 
  
addCommandHandler("toggle", 
    function() 
        for i, v in pairs (objects) do 
            local object = createObject(v.model,v.x,v.y,v.z,v.xr,v.xy,v.xz) 
            -- Your code here  
        end     
    end 
)

objects = { 
    {model = 3095, x = 0, y = 0, z = 6, rx = 90, ry = 0 , rz = 0, tex = "texture name here"},

            -- Your code here  
        end     
    end 
) 

Oh... Thanks.

EDIT:

Is it possible to make something like this (two textures):

objects = { 
{..., worldtex = "sam_camo" and "bonyrd_skin2", tex = "texture1.png" and "texture3.png"}, 
{..., worldtex = "bonyrd_skin2" and "sam_camo", tex = "texture2.png" and "texture4.png"} 
} 

OLD:

Does it make sense if coordinates are like this:

objects = { 
    {x = 0, y = 0, z = 6, rx = 90, ry = 0 , rz = 0}, 
    {x = 10, y = 0, z = 6, rx = 90, ry = 0 , rz = 0} 
} 

or this:

objects = { 
{x = 0.0000, y = 0.0000, z = 6.0000, rx = 90.0000, ry = 0.0000, rz = 0.0000}, 
{x = 10.0000, y = 0.0000, z = 6.0000, rx = 90.0000, ry = 0.0000, rz = 0.0000} 
} 
  

?

I also think that you made mistake here:

local object = createObject(..., v.xr,v.xy,v.xz) 

Shouldn' t it be like this?

local object = createObject(..., v.rx, v.ry, v.rz) 

Anyways, thanks everyone.

[Walid]

1) About the first question it's not posible , maybe you can use table inside the main table like this

local table = { 
{..., worldtex = {"sam_camo" ,"bonyrd_skin2"}, tex = {"texture1.png","texture3.png"}} 
} 

2) About second question both are correct.

3) The last question i just gave you an example you can fix it by yourself later.
