-[UIImageView _resolveAndDiscard]: unrecognized selector sent to instance 0x157fb5be0

Has anyone generated this while using scene module? i cant think of how an unrecognized selector would be sent when im not manually sending objc selectors...

mikael

@stephen, how are you using UIImageView in scene? Maybe there is some clue there.

How consistent is this crash?

Also, I think you were aware of the crashiness of load_from_url, so you are probably not using it?

this is why its so odd.. 😬🧐🤓 im not using UIImageView. also nt using `load_from_url. the crash was pretty consistent, would crash about every 5 time i would us Run.. but whats even more odd is once i commented out some code that handled a pond for my game it sems to have stopped.. ill post the code.. but it probably wont run or u without everything and assets.. but ill show what i was alling how and that its all fom scene (i know scene use ui but i figured id need to exclusivly call UIImageView to get this issue)

I believe that is everything that would be used with pond for now. Any Ideas?

Can you install @dgelessus 's faulthandler, then reproduce the crash? That will show the full stacktrace at least.

Which code commented out fixes the crash?

I have seen some strange unrecognized selectors when something gets totally borked, maybe some memory got overwritten.

sorry for the weird commenting lol i just coppied from script

yea i will give FaultHandler a try Thank You!

Try commenting out the self.Animate. I wonder if the repeat forever could be a problem, say if there was a memory leak somewhere.

stephen

@JonB Good Idea!

stephen

@JonB i cannot seem to find FaultHandler

stephen

@JonB @mikael I believe i found the one issue.


        r1= SpriteNode(
			Texture(ui.Image.named('./assets/player-ring1.png')),
			position=p.size/2,
			scale=0.5,
			speed=2,
			alpha=0,
			parent=main)
		r2= SpriteNode(
			Texture(ui.Image.named('./assets/player-ring2.png')),
			position=p.size/2,
			scale=0.5,
			speed=2,
			alpha=0,
			parent=main)

i think Texture(ui.Image.named('./assets/player-ring1.png')), is whats crashing but i agree on the memory leak. so im going to go over every object and see if i can find what hanging up..

@cvp ... guess who looked right at it earlier and didmt see it... 👉🏼🤦🏻‍♂️

@stephen, I'm confused by the indentation and code sequence in this region of class Pond. Maybe the problem is here?

stephen

@njm i see lol this was a section that was commented out by another script i been working on and the uncomment function is still buggy. normally that code is like the following. otherwise the script wouldnt run at all


    for brush in self.fishingNodes:
		from random import choice
		x, y = choice(self.fishingSpots)
		brush.run_action(Action.move_to(x, y, 5))

	self.Animate()

@JonB @mikael @cvp @njm turned out he ui.Image calls inside Texture combined with two corrupted images was the problem. when i removed the ui.Image calls i still crashed but with no stack report at all then i somehow came across two png files the were 101b in size instead of the 1.1MB lol no more crashes. thanks for all the help everyone!

cvp

@stephen 👍
