    setTexture and SetTextureRegion incompatibility

    in Bugs and issues
    I have a bitmap where I want to used both Texture or TextureRegion depending on the state of the game.

    But this is the problem:
    1. setTexture( put texture region as parameter) = error :(
    2. setTextureRegion(put texture as parameter) = error :(

    How to fix this? Thanks.

      @MoKaLux Thanks for the feedback :) Here is the code
      -- for example 1 bitmap and 2 textures (I name it texture_1 and texture_2
 
texture_1  = Texture.new('images/button.png')
texture_2  = TextureRegion.new(Texture.new('images/button.png'), 0, 0, 50, 50)
 
bmp = Bitmap.new(texture_1)
 
-- then I want to update bmp texture anytime in the game
 
function update_image(texture_name)
	bmp:setTexture(texture_name)
	-- bmp:setTextureRegion() 
end
 
update_image(texture_1) --> this works
update_image(texture_2) --> this is an error. So I need to use bmp:setTextureRegion()
 
--[[ Is there a way to feed both normal texture  and textureRegion to a Bitmap in a single function?
   Why I need this? :
   My graphics assets are composed of texture atlas and single frame images. Sometimes I need to use the single
  frame image and sometimes I need to use the atlas for a single Bitmap.

      No, you can't use the same function for both object types, but you can call the right function according to your parameter:
      function update_image(texture_name)
	--bmp:setTexture(texture_name)
	-- bmp:setTextureRegion() 
	bmp["set"..texture_name:getClass()](bmp,texture_name)
end

      @hgy29 nice trick, didn't think of that - the beauty of Luau...
