I am making a sprite sheet for my game but as development is progressing, I find myself having to replace some of the sprites on the sprite sheet with improved versions.
but the problem is it ruins all the slicing of that sheet and I have to do the slicing all over for the entire game, just because of one sprite that I wanted to modify.
I would like to use something similar to NGUI’s Atlas Maker.
Actually, can I make use of NGUI’s Atlas Maker to make and modify sprite sheets?
How do I go about modifying my sprites without affecting the other sprites?
This shouldn’t be a problem, as long as you keep the same dimentions. If newer version of your sprites have exactly the same width and height of the older ones, you just have to be careful to place them exactly at the same location inside the graphic file. Always keep the older sprites close the bottom left, and make the file grow to the top right as you add new sprites…
I use photoshop to edit my sprites sheets, and have absolutely no problems with slicing, but I always make sure to replace old sprites with newer ones with exacly the same with and height. This is a matter of disicpline, you don’t even need an special tool.
If you do make changes in heigh and/or width, then you certanly will have problems with slicing and will be working extra time, all the time.
