Texture lässt sich nicht als renderTarget setzen

RenderTarget = {}
inherit(ParentsChilds, RenderTarget)

	self.depth = depth or 1
	self.renderTarget = DxTexture(self.width, self.height, self.textureFormat, self.textureEdge, self.textureType, self.depth) -- Hier hab ich auch die Funktion dxCreateTexture probiert - selber Fehler
	self.hasBeenModified = true

	self:addChild(child)


	self.m_draw = function() self:draw() end
end


function RenderTarget:setTarget(clear)
	--return self.renderTarget:setAsTarget(clear) -- Keine funktion ?? well fuck mta
	return dxSetRenderTarget(self.renderTarget, clear)
end

		dxSetRenderTarget()

end




function RenderTarget:destructor()
	removeEventHandler ( "onClientRender", root, self.m_draw )
