New page

__NOTOC__
{{Client function}}
This function sets the render function of a dgs custom renderer.

==Syntax==
<syntaxhighlight lang="lua">
bool dgsCustomRendererSetFunction( element customRenderer, string renderFunction )
</syntaxhighlight>

===Required Arguments===
*'''customRenderer:''' A dgs custom renderer you want to set.
*'''renderFunction:''' A string of lua code which will be the new renderer of the custom renderer.
**'''Predefined Variable of renderFunction:''' For detail, see [[dxDrawImage]]
***'''posX:''' Absolute X position of the renderer's bounding box.
***'''posY:''' Absolute Y position of the renderer's bounding box.
***'''width:''' Absolute width of the renderer's bounding box.
***'''height:''' Absolute height of the renderer's bounding box.
***'''self:''' The custom renderer itself.
***'''rotation:''' The rotation of renderer's bounding box.
***'''rotationCenterOffsetX:''' The rotation center offset x of renderer's bounding box.
***'''rotationCenterOffsetY:''' The rotation center offset x of renderer's bounding box.
***'''color:''' The color to be applied.
***'''postGUI:''' Whether the dx draw is require postGUI

===Returns===
Returns ''true'' if successfully, ''false'' otherwise

==Example==
<syntaxhighlight lang="lua">
DGS = exports.dgs
local customRenderer = DGS:dgsCreateCustomRenderer() --Create an empty custom renderer
DGS:dgsCustomRendererSetFunction(customRenderer,[[
local texture = dgsGetProperty(self,"customTexture")
dxDrawImage(posX,posY,width,height,texture,rotation,rotationCenterOffsetX,rotationCenterOffsetY,color,postGUI)
dxDrawImage(posX-width,posY-height,width,height,texture,rotation,rotationCenterOffsetX,rotationCenterOffsetY,color,postGUI)
]] ) -- We can set the function here
local tex = dxCreateTexture("exampleTexture.png") --Create a texture
local image = DGS:dgsCreateImage(300,300,200,200,customRenderer,false) --Apply the custom renderer
DGS:dgsAttachToAutoDestroy(tex,image) --The texture will be destroyed when the image destroys
DGS:dgsAttachToAutoDestroy(customRenderer,image) --The custom renderer will be destroyed when the image destroys

setTimer(function()
destroyElement(image)
end,10000,1)
