Here's an animated progress bar (macOS style) I did years ago. I just tried running it the snippet and it doesn't work anymore. In the loop where I set the sprite's UV offset, I had to change the V value from 1 to 0 to see the texture at all. And the image wrap doesn't seem to work anymore. It's not tiling on the sprite like it used to.

I'm not sure about my compiler version, but the IDE says 2019.09.27 (from steam)

Im not sure that this is the exact issue but the wrapping changed along time ago on release of version 2.0.20

Specifically:
Quote: "Using SetImageWrapU or SetImageWrapV with mode 1 (repeat) on an image that is not a power of two will now do nothing"


Your 20x12 image is not power of two

The SetImageWrapU/V functions also state the same:
SetImageWrap documentation wrote: "To use UV values outside 0-1 successfully on all platforms the image in question must be a power of 2 in width and height, and not be part of an atlas texture."



but, there is an easy fix that works in most cases, call these before loading the image:

SetDefaultWrapU(1)
SetDefaultWrapV(1)

Then it works again...at least on my pc it does and on the phone too.

Ah thanks. I read power of 2 and thought multiple of 2. I wrote the code in 2015 and it apparently used to work back then. (otherwise I wouldn't have posted it). But your solution has resolved the problem.
