Thank you, gimmick2509! I think the problem I have with that approach is timing. So I have a schedule that runs every second. After 10 seconds (or whatever the user wishes), that's when I load the next image. This allows me to show a countdown timer in the corner of the screen with the number of seconds remaining before the next image is shown.
My newbie thinking is I would need to set up another "temporary" schedule/clock interval of say like point one ( .1) seconds which would reduce the opacity. However, I found that approach to rather choppy depending on the size of the next image and reading it from disk. I also feel like have 2 more temporary schedules is not clean (1 to fade out, then 1 to fade in) Is this possible to do through some sprite animation? Also, how can I load the second image during the 'countdown' time without delaying said countdown? I've found that if I do a heavy load task, all pyglet processing stops until that task finishes. In real terms it seems like if i'm counting down from 10-9-8 and i do a load that takes 2 seconds, the countdown pauses at 8 for 2 seconds and resumes at . It'd be nice if I could load the image into a sprite in the "background" without affecting the countdown. I'm sure there is a clean/elegant way to do it, I'm just too new at this to know what it is.
