How do I make my character die when touching a specific object?

Unity Engine

Hi,

Im still in the learning process of Unity,
and I was wondering how I can make certain objects do damage.
So if my character takes a certain amount of damage it dies and restarts the game.

Thanks!

Firstly, Your character should have health:

public int health = 100;

and your enemy should have damage:

public int damage = 10;

On your character you should have a function to take damage:

public void Damaged(int damage)
{
    health -= damage;
    if(health =< 0)
    {
        // Reload your scene using the new SceneManager
    }
}

On your enemy you should have a function which gets called to deal the damage - On a collision?

void OnCollisionEnter(Collision col)
{
    // check If you collide with the player
    // I dont remember if you check it with col.tag - needs checking
    if(col.tag == "Player")
    {
        col.GetComponent<ScriptWhichHasHealth>().Damaged(damage)
    }
}

EDIT:
This may not be prefect but it is the sort of approach that I would take.
(may have a couple of small error within the code - is untested)

something messed up with the last part, it says col doesnt contain a definition for getcomponent

There are a couple of syntax errors in that post however they should be fairly easy to solve. This one for example instead of col.GetComponent should probably be col.gameObject.GetComponent
