If Check Colliding GameObject Variable
I'm looking for a way to check a variable in the script of a gameObject my player is colliding with. Here is what I currently have:
void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.tag == "Enemy")
{
hitPoints = hitPoints - 1;
}
}
What I want is for "hitPoints = hitPoints - 1;" to fire only if the colliding gameObject has the tag "Enemy" and if that specific Enemy instance's own hit points variable is above zero. How would I do that?

You need to get a reference to the other object's script using GetComponent, then you can access the variable provided it's public.
void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.tag == "Enemy")
{
EnemyScript enemy = collision.gameObject.GetComponent<EnemyScript>();
if(enemy != null && enemy.hitPoints > 0)
{
hitPoints -= 1;
}
}
}
Replace 'EnemyScript' with whatever you call your enemy's script.
