What is that error ? [erase: Condition "p_I->data != this" is true. Returned: false]

Hello everybody!

I am on v3.2.1, and randomly experience that error. Sometimes it doesn't occur at all, but sometimes it prints dozens of times until the game finally crashes.

Do you know where it could come from?

I didn't find any thread relating the same issue...

Welcome to the forums @TimDo!

Does the Godot console give a hint as to where the file that is causing the issue might be? It is probably a C++ error that is being printed, but usually the Godot editor mentions which file and roughly which line. Can you post a screenshot of the error and/or the error log? That might help deduce what is causing the issue, since we might be able to find where in the source code is generating the issue and why it occurs.

Thanks a lot @TwistedTwigleg!

I am sorry, there is indeed the following information, detailing the error: <C++ Source> ./core/list.h:159 @ erase()

I am unfortunately unable to read it and don't know how to use it...

By the way, the error is not random after all. It occurs when, in my platformer, the enemies, generated infinitely, exit the screen and queue_free after the player death. I also found the reason of the crashes, which were unrelated with this matter.![] (https://i.imgur.com/IPa0cUe.png)

Cool, thanks for posting the error! I'll try to take a closer look at what could possibly be causing it once I have the time.

TimDo

Alright, thanks a lot! I'll try on my side to isolate better the code related to the error.

Well, I found what it was!

Every time an enemy spawns, its position.y is set to the one of the player, and I forgot to take in account the player death... The engine was indeed trying to get the position of a null instance.

At least we know what this error is now ;)

Thank you though for your quick intervention!

Awesome! I'm glad you were able to figure it out. :smile: I was meaning to take a look earlier, but got distracted.
