public class GameManager : MonoBehaviour
{
    public bool EnableHighContrast;
    public bool PlayerWon;
    public float PlayerUnitsMoved;
    public int PlayerDeathCount;
    public float PlayerHealth;

    public void PlayerTakeDamage(float damage)
    {
        PlayerHealth -= damage;
        if (PlayerHealth < 0)
        {
            PlayerDieAndRespawn();
        }
    }

    public void PlayerDieAndRespawn()
    {
        return;
    }
}

I couldn't contain myself.

Should it be

PlayerHealth <= 0

Otherwise the player could have 0 health and not die? I’m sleep deprived so forgive me if I’m wrong

I know this is /c/Progammerhumor, but I wanted to pull on this thread a little bit for my own edification. I'm a Python guy and have been a while, but I've dabbled in other languages. The screenshot says "MonoBehaviour" which makes me assume this is mono or a .Net-like language (you know what happens when you assume).

If your player health is a float, would mono or .Net have an issue comparing the float with integer zero "0"? I mean, it seems like floating point precision may make it impossible for it to ever "equal" integer zero, but it also seems like the code isn't accounting for that precision error.

Am I overthinking this?

As a noob in unity and programming, my understanding is that MonoBehavior only means that this script has to be attached as a component to a game object to function. And has no other meaning - but correct me if I'm wrong please.
