First, it would help if we could see what you are using to display the Health here. You did not include the definition for that.

Second, why are you destroying the asteroid GameObject (Destroy(col.gameObject);), but not the bullet? Generally, once a bullet hits something it is considered destroyed.

Third & Fourth, how is it that you are seeing collisions on a GameObject with a tag of “Health”? I wouldn’t expect that to have a Collider attached to it. Also, you are simply setting it twice to a value of 100 there. Did you mean: Health = Health + 100?

At the end of all this you can update the displayed value for Health, or you can create a method that does it and call that each place where you are changing the value of Health. The latter solution would mean you don’t update it if Health is not changing and that method would update the displayed value.

You might also want to set Health to 0 when it is <= 1, just as you don’t let it become greater then 100 you might want to set a lower limit of 0.
