Hey guys. All I wanted to do was create a function to take an instance of the texture class I created and tile it. Simple enough. Weirdly though, it only works with certain textures. Attached is the partial code of my texture class (the tileImage function), and the partial code in my main file (where you put code to render the textures).
No matter what I do, text_babyPixel (which is just a 1x1 white pixel I was planning on using for backgrounds) will just not display and the program crashes. But, text_rightGrid and text_leftGrid (which are just like a chess board pattern) both tile correctly when ran individually. However, when the program is run and text_rightGrid and text_leftGrid’s tileImage functions are called, they both are displayed, and the specified y coordinates are fine, but for some reason the x coordinates are weird. They get bunched up together either on the left side or right side of the screen. Any idea. Thanks!
