Dash Script Error

anyone know how can i solve this?

Dash Script Error

[toxic dune]

Seems like theres probably other logic deleting it, is there any scripts that delete other objects on the enemy?

[tulip egret]

yes i have a script that deletes enemies. but it shouldn't touch my character at all. if an enemy spawns outside my walls, it deletes the enemy and triggers the respawn action. I'm not sure though right now that thing doesn't seem to be working properly. Let me assign that deletion code as well.

https://hastebin.com/share/onigocopub.csharp here.

[tulip egret]

But I didn't write this code. I found this on google.

[toxic dune]

I would add a debug at least or breakpoint to see if any deletion code is happening. Your game objects wont randomly delete themselves without you calling it

[tulip egret]

like that?

[toxic dune]

sure, or anywhere that you are calling destroy if it exists in more places

[tulip egret]

I think I solved the problem.

I don't think it has anything to do with that script. So yes, that script is probably destroying it, but I was using the trail.Clear() method, which deletes the old trail points after dash in my dash script. When I removed it from the dash script, the error was fixed, but now every time I throw a dash, my old dash points are drawn to the screen.

[toxic dune]

trail.clear wouldnt remove anything from your player hierarchy still. try not to associate random things to solving the issue

something is destroying it, or moving it in a place where you didnt notice (probably unlikely)

[tulip egret]

I tried so hard to get this screenshot bruh.

[tulip egret]

however, when I delete the trail.Clear() method, it draws every location I put dash on the screen as seen here.

[toxic dune]

trail.Clear doesnt have anything to do with your player deleting

[tulip egret]

so what then? so I don't have any other script that can delete any gameobject.

[toxic dune]

its possible that the trail itself is being hit, or some object. its hard for me to understand the code since the comments arent english.
Did no debugs print at all when your player was deleted?

[tulip egret]

nope

[tulip egret]

Wait, I'll translate the comments to English and upload them again.

[toxic dune]

Honestly itll probably be better if you just try to isolate which script the error is in, possibly by disabling components or going through them all to see what logic is happening

Maybe you can even put a breakpoint in OnDestroy and try to see the stacktrace to see what called it, though im just speculating here because i havent done this before

[tulip egret]

https://hastebin.com/share/jubalahiyo.csharp here is the new code

[toxic dune]

I would try the OnDestroy, add a breakpoint and try to see the call stack

[toxic dune]

OnDestroy being a unity message, which is called by unity when your object is being destroyed

[tulip egret]

oh so you're telling me to call that function?

[toxic dune]

no.. let unity call it because your object is being destroyed

then see the call stack so you can attempt to see what calls on destroy

[tulip egret]

like that?

[toxic dune]

should be fine like that, although im unsure if that breakpoint will be called on the { ever. Ive never done that personally

[tulip egret]

actually i choose the row where start with private. but visual studio behaves as if i clicked below line...

[tulip egret]

Where should I look now to see that callstack?

[toxic dune]

did you attach the VS debugger and actually get the breakpoint called?

the callstack would be in VS

[tulip egret]

oh nope sorry wait a min.

[toxic dune]

ah what you could do actually is this
https://forum.unity.com/threads/how-to-check-if-a-gameobject-is-being-destroyed.1030849/#post-8284941

then just add like a Debug.LogError in there, to see the callstack if its relevant

[tulip egret]

like that?

[toxic dune]

Seems fine, try running it and seeing if it ever prints

that trail renderer error might be just misleading you, if that somehow is running first and pausing your game before this error prints. Try unpausing once if thats the case

[tulip egret]

not logging

[tulip egret]

hmm

[toxic dune]

is this OnDisable script on the object being destroyed

[tulip egret]

The human continues to appear on the scene. and no, I put the script in the character movement script within the human itself, not in the destroyed object. (human still appears on the scenebecause my character's collider still exists even though it's gone.)

[toxic dune]

put this OnDisable in a new script and put that on the object being destroyed

on disable wont be called if its not disabled/destroyed

[tulip egret]

oh okay

okay putted.

object is not destroyed just deactivated but why

[toxic dune]

can you show the call stack of that error, click on it and expand the little area at the very bottom

[tulip egret]

this?

this line

[toxic dune]

Damn I really was hoping that would print out more

if you are completely unsure what is destroying/disabling your object, I would start by removing components and trying to replicate it. See where this exactly comes from

[tulip egret]

I suspect trail.clear() I put the trail.clear line in this line in the on cooldown end function, if there is no problem when it is like this, I think the problem is caused by this. When I searched the internet a bit, it said that trail.clear disables the trail and when you call the trail again, objects can be destroyed.

[toxic dune]

🤔 did you enable auto destruct on your trail renderer?

[tulip egret]

yes

[toxic dune]

ah well i guess that solves it.

[tulip egret]

That's not the problem...

[tulip egret]

hm?

[toxic dune]

https://docs.unity3d.com/Manual/class-TrailRenderer.html

AutoDestruct Enable this to destroy the GameObject to which the Trail Renderer component is attached after it has not moved for Time seconds.

you dont want auto destruct

[tulip egret]

omg wtf

[toxic dune]

honestly dont know why they made it destroy the object entirely

didnt even know this was a thing myself, i dont use trailrenderer much

[tulip egret]

okai solved

thx dude tysm

[toxic dune]

lol np, honestly i never wouldve guessed it was the trailrenderer destroying the whole object until you said objects can be destroyed. You probably shouldve checked the api after seeing that 😅
