Frame blending?

Hey, just wondering if anyone got a plugin or easy solution for frame blending? I don´t need anything fancy, just instead of instantly switching from frame 1 to 2, blend over with opacity over a set time. I know it´s doable with events obviously, but it requires creating extra temporary Sprites on top with fade behavior and I feel like it could lead to a bunch of annoyances in the long run. Or I could create the animation as a sprite Animation and just have this play but that also feels a bit meh, especially if I end up changing the sprite and having to redo that animation.

Maybe I´m overlooking some easier solution? Or maybe someone has the sudden urge to write a behavior? :D

Cheers

Fading sounds like a good idea. On fade start, spawn the the same object under itself and set the animation frame to self+1. On fade end, start the next fade.

For a looping animation you can use a conditional expression to set the next frame to keep it compact.

If you need persistence, use an invisible helper sprite as the base object.

Yeah that´s pretty much what I hoped to avoid but it´s the best solution so far. I actually don´t even need to blend a continuous animation, it´s more a change of a state. Basically my objects can have several different states and when the state changes it should not just pop into the other state instantly.

You can try having the base object persistent and change immediately, but spawn a copy with the previous animation frame on top of it and fade?
