Game Crashing without Error in Debug-Console (FIXED: 3.2.2 RC1 is bad. RC2 works)

whiteshampoo

Hi,

i need help with a project for a gamejam. Today is the deadline, and i'm really stuck.

The game crashes randomly, and without a reason. The game stucks for s seconds, then the game-window closes and "--- Debugging process stopped ---" Usually i find all my mistakes by myself, but this time Godot give me absolutly no information what went wrong, and i have NO idea where to search...

Here is the project: https://ufile.io/uzjg3ctp

I'm using 3.2.2 RC1 (without C#) on Windows 10

I would like to say more about the problem, but i really really don't know how to locate the problem... Please help :'(

If you launch Godot from the command line, it may show you more detailed error messages.

i already tried with commandlineoptions "-v -d" (verbose and debug), but nothing useful here, too :(

I have tried to print the name + "start"/"end" at every start/end of every possible function/method, but it seems to crash between frames... Help :(

I tried now with (Manjaro) Linux and Godot 3.2.1 stable. Here i can gat some output:

[KinematicBody2D:41431]

but this does not really help me.... :(

EDIT: It's not realiable a KinematicBody2D

Have you tried Godot 3.2.2 RC2?

Edit: Running the project in the editor with Godot 3.2.2 RC2 works for me! I'd try exporting with Godot 3.2.2 RC2 and see if that fixes the issue.

also crashing in RC2... Also exported (64&32bit)

EDIT: because i'm an idiot. i downloaded the RC2, but started the RC1 executable.

Thanks, is working now! <3

Release-Export still crashes :D

Edit: Jokes on me. That didn't fix it. Back to square one.... Edit2: Should have read your title, RC3 fixed it for me

I made an account just to answer you and now this site makes me type it twice because the first one never got posted..... Anyway: I was facing a similiar issue as you. Random but semi reliable crashes. After lots of trial and error i found out that it sometimes crashed when instantiating a specific scene. That scene consisted of a Area2D using a CollisionPolygon2D. I deleted the CollisionPolygon2D and started using a CollisionShape2D. That seems to have "fixed" it for now. I hope that helps you, because debugging without any engine feedback is incredibly annoying.

The first one was stuck in the moderation queue, likely because your account was not verified when you posted.

I just saw that RC3 is out. i'll try today evening if it fixes my problem. In the meantime i "released" my game as debug-build to the gamejam. I'm not a big fan of this, but it runs without crashing :)

(If someone is interested (Sourcecode/Project-Folder included) --> Link <-- )

EDIT: Still crashing in Release-Build with RC3

RandomShaper

I've been trying to debug the problem. The only things I've found is that at runtime (using a release build) the velocity variable in Player.gd can be null after these lines (I've seen it happening after one or the other in different sessions):

velocity = WannaHave.global_position - global_position

velocity = Target.global_position - global_position

Therefore, the subsequent call to velocity.normalized() crashes.

I'm not sure if this will shed some light. Hope it does. :)

Thank you RandomShaper! You are right, i never check if the Vectors are Zero. But i don't think thats the main problem, because this should happen very rarely. (should be fixed anyway) I think the problem is that i somewhere or somehow handle queue_free() wrong. When i try it in 3.2.1 stable is crashes in the editor, saying that something happend with previously freed stuff. (i don't have it here atm) 3.2.2: RC1 crashes in the editor without saying something RC>2&stable works in editor but not in release

still trying to figure out what exactly i'm doing wrong, and why 3.2.2 doesn't tell me something :/

I am having this exact issue. Sometimes it works normally, then after launching the game it closes without printing what happened in the log file. Something to do with scene changing but I am not 100% sure.
