This function applies a shader to one or more world textures.

[[{{{image}}}|link=|]] Tip:
  • The resource shader_tex_names can help in finding the names of world textures.
  • When replacing the texture for a ped using the CJ skin, set textureName to "CJ"
  • The shader inherits the render states of the original when it is drawn, so texture stage 0 will already be set to the original texture.
  • When using with a 'ped', ensure you have set 'ped' or 'all' in the elementTypes when calling dxCreateShader
  • CJ body parts textures can be replaced by using: "cj_ped_head", "cj_ped_hat", "cj_ped_torso", "cj_ped_legs", "cj_ped_feet", "cj_ped_glasses", "cj_ped_necklace", "cj_ped_watch" and "cj_ped_extra1". Latest version of shader_tex_names will show what is being used.

Syntax

bool engineApplyShaderToWorldTexture ( element shader, string textureName [, element targetElement = nil, bool appendLayers = true ] )

OOP Syntax Help! I don't understand this!

Method: shader:applyToWorldTexture(...)

Required Arguments

  • shader: The shader which is to be applied
  • textureName: The name of the world texture to apply the shader to. Wildcard matching e.g. "ro?ds*" can be used to apply to more than one texture at a time.

Optional Arguments

  • targetElement: The element to restrict applying the shader to. If this is not set the shader will be applied to everything using the texture name. Valid element types for targetElement are vehicles, objects and peds.
  • appendLayers: --TODO

Returns

Returns true if the shader was successfully applied, false otherwise.

Example

This example will apply a shader to the "des_logwall" world texture (which is used by the house near the 'play' gamemode spawn point) 

myShader = dxCreateShader( "hello.fx" )
engineApplyShaderToWorldTexture( myShader, "des_logwall" )

This untested example will apply a shader to the current vehicle of the local player 

myShader = dxCreateShader( "hello.fx" )

addEventHandler("onClientVehicleEnter", root,
    function(thePlayer, seat)
        local theVehicle = source
        if seat == 0 and thePlayer == localPlayer then
            engineApplyShaderToWorldTexture( myShader, "vehiclegrunge256", theVehicle )
            engineApplyShaderToWorldTexture( myShader, "?emap*", theVehicle )
        end
    end
)

addEventHandler("onClientVehicleExit", root,
    function(thePlayer, seat)
        local theVehicle = source
        if seat == 0 and thePlayer == localPlayer then
            engineRemoveShaderFromWorldTexture( myShader, "vehiclegrunge256", theVehicle )
            engineRemoveShaderFromWorldTexture( myShader, "?emap*", theVehicle )
        end
    end
)

Changelog
