This function sets the render function of a dgs custom renderer.

Syntax

bool dgsCustomRendererSetFunction( element customRenderer, string renderFunction )

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

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:dgsSetProperty(customRenderer,"customTexture",tex) --Make a reference for the texture that can be used in the render function.
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

	destroyElement(image)
