I have not run into this issue yet and I'm on day 2 of trying to solve it, so I've gotta come ask.
I have a player that when you press Z, will attack with a sword. I have my sword scene, which is a node2d with an animated sprite. That sprite has 7 frames. My script code for it is as basic as it gets for the moment, I play the sprite on _ready and a signal is attached to free the object when the animation completes.
It does not work, however. If I remove queuefree from the animationcomplete signal and set the sprite to loop, it plays fine, otherwise it does not show at all. It seems like it's instantly being completed as soon as it's ready.
What could be the issue here? I have a ton of other scenes and all the animations work fine, I'm not sure why this one being so simple is being a problem. Here is the sword script:
$AnimatedSprite.connect('animation_finished', self, '_on_animation_finished')
Simple. With queue_free() removed and the animated sprite set to loop, I can use it in my main scene fine (although it loops forever), and I can f6 and test and see it. Otherwise, even testing the scene alone, nothing shows up.
