(Solved) Preloading Cropped Images

[SypherZent]

Is it possible to preload cropped images?

I use large spritesheets and crop frames with Python.
However, the sprite always lags on the very first playback, since it hasn't preloaded the cropped frames.
I tried using renpy.predict on every frame, but that did not work.
Once the animation has run the first time, it doesn't lag anymore.

Up until now, my solution has been to run the animation off the screen the first time around.
However, that is lagging text and showing of sprites in game, so I've had to create a Loading screen.

Now, I want to eliminate Loading altogether.
So, is there any way to preload sprites without having to lag the game and play them through?

Found a solution.

Code: Select all

renpy.cache_pin('spritesheet.png')

By using renpy.cache_pin on every spritesheet (rather than the cropped frames) that will appear in selected stage, the first playback is much faster and the loading time is significantly reduced (from 10 seconds down to about 1.5 seconds). RAM jumps a bit (from 135 MB to 235 MB), but it is a much better solution than the loading or lag felt by trying to force first playback of every cropped frame.
