my ship with the laser keep going up…
What is it exactly that is happening and where? Would you be a little more specific?
If you are worried about the images “moving up” on the image sheet, then you don’t need to worry at all. Most likely TexturePacker is automatically arranging your images according to best fit and it doesn’t matter at all as to where those individual images on the sheet are. TexturePacker outputs a lua file with the information on all assets on a sheet and Corona will use it to find the correct sprites/frames.
