No line… The console not open the line error of script.
This is in the console:
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
SpawnScript+<Spostamento>c__Iterator1.MoveNext () (at C:/Users/Dany/Desktop/Project/Assets/Scripts/SpawnScript.cs:24)
EDIT: Line 24 of SpawnScript.cs?
I have a Quad,the spawner,wich i generate the obstacles… this run from right to left.
On the Left,next the scene,there is a quad destroyer,this destroy my GameObject obstacles.
I think,the problem is : Destroyer catch the obstacle,destory it,but the spawnscript try to access it (to move to right)
Yooo man!! It work… my forgetfulness. I love you!!
Another problem:
I have create another two quad with spawnscript for generate the trees and clouds for the background.
I add at it a polygon collider 2D,with “is trigger” enabled.
When i simulate the game,i have a loss of frame,it drops by 30-40 fps!!!
How can i solve it? Is too much stress for Gpu?
P.S. How can i stop the simulation,when it looping and freezing?
What’s happening here is that, when you add a collider with no Rigidbody to an object, Unity treats that object as a static collider. It does some optimizations to make physics run better. However, those optimizations take time to do, and anytime the static colliders of a level change, it has to re-do those optimizations. You’re moving them every frame, so it has to redo those calculations every frame (I think it might redo those optimizations every time you move the objects - if you have several being moved, that’s several times per frame it recalculates.)
Short answer: if you have a collider that is going to move (especially if it moves every frame), ALWAYS add a Rigidbody (set it to isKinematic).
I’m sorry,I’ll explain:
treeSpawner is my quad with spawnerScript (the same of the obstacle generator script,the spawnerScript on the first post).
I use it for generate trees (these are a “part of background”).
When the quad generate the prefab tree,game loss frame!
i have the same problem,
MissingReferenceException: The object of type ‘PlayVideo’ has been destroyed but you are still trying to access it.
here my script.

@Nabil_fx , I’m assuming you posted the question here by just searching for the error message you got and finding a forum post that matches it; however this is a very different problem that just happens to result in the same (very common) error message. I recommend making a new thread instead, so as not to confuse the discussion
you set up the parent, then you distory the gameobject so , you make mistakes;
you can use word “try"and “catch’ in “try” you can add a gameobject, in” catch” you can set up the parent.
