Unparented Object not falling

Ok so i have a gun model parented to the hand of my AI so i was able to get the gun to unparent from the hand of the AI when the AI is killed but to get the gun to fall i added both a mesh collider and rigidbody to the model so when i started having weird issues or example the gun starts floating outside the hand of the AI or if i check IsKinematic on the rigidbody when the AI dies it doesn't fall it just gets stuck in the air, i also tired unchecking IsKinematic and freezing the position and rotation but that doesn't work either. So i'm curious to know if there's a fix for this.
Thanks

Code (CSharp):

1. public GameObject Gun;
2. void OnAIDeath()
3.         {
4.    
5.             Gun.transform.SetParent(null);
6.        
7.         }

That's some part of the code i used

 

just a guess, maybe rigidbody is sleeping,
https://docs.unity3d.com/ScriptReference/Rigidbody.WakeUp.html

 

Hmm i'll try this out later thanks
But are there any other things i could try out?

 

i'd try setting parent this way also,
Gun.transform.parent = null;

and check in hierarchy that it actually works (unparents it)

need to disable [ ] isKinematic, and disable those freeze positions too, it seems you tried that.

 

Lol yeah i tried that i'll just try this

first and see it it works if it doesn't i'll come back

 

The thing is if I disable isKinematic the Gun starts to move on its own and doesn't aim properly at all

 

did you try disabling after unparent?

 

Ok i finally got it to work there were two things i did
1.) I moved the script to the parent model(yes i know i feel like a moron now)
2.) I did something like this i first made isKinematic true and then i added the following lines of code

Code (CSharp):

1. public Gameobject Gun;
2. public Rigidbody  rig;
3. void OnAIDeath()
4. {
5.       Gun.transform.parent = null;
6.       rig.isKinematic = false;
7. }
