Lives sytem

I have been trying to get a life system to work in my fist small game. But have now made a small test to see if i can get it to work. But no luck yet.

The test is just a ball and a kube object. If ball run into the cube. The ball dies (destroyed)
Wait a few sec and then be respawned.
For now the ball dies but not appear again after a few sec. I get a message that i still trying to use a destroyed object

What line of code and what script has the error?

 

Not give any specific Line number.. But when clicking on the error message it comes to The gamecontroller Line 35.

 

Then somewhere in your code you are destroying Player. I can't tell if Player is a scene object, or a prefab, but the way you should do this is you have a Player prefab and instantiate it.


Also, where are you getting your reference to Player on line 21 in LivesScript? That looks like it should be producing a compile error as written.

 

Last thing first. The Player.lives refer to the player script Lives.

Im a bit new to everything yet.

Have not made the object Prefab that this was just a setup to test out a Lives system.
In the main program they are prefab
.
Edit: I removed the destroy in livesript and put it above the instanciate in GameController.
Destroy(this.gameobject); But now the player does not get destroyed when it hits enemy. But it trigger the event. Have a Debug.log telling me so.
