setTexture and SetTextureRegion incompatibility

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.

    some sample code please with the setTexture so we can test on our side? o:)

  • @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:setTextureRegion() 
    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:setTextureRegion()

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