Health Drains over time script?

Questions & Answers
1

I am making a Sci-Fi game where the player it’s on a planet without oxygen.
I want a script where the player health drains over time, and when he collides with some objects (Like his spaceship or dead bodies) he refills his health.
I tried to make it alone, but my coding it’s…rusty.

you may use coroutines ( im in C#) …

bool noOxygen;
bool drainingHealth = false;

void Update()
{
   if (noOxygen && !drainingHealth)
   {
      drainingHealth = true;
      StartCoroutine("DrainHealth");
   }
}

IEnumerator DrainHealth()
{
   health -= 1;
   yield return new WaitForSeconds(secondsBetweenHealthDrain);
   drainingHealth = false;
}

Ofcourse you need to adjust the time between drains of health happen ( best to adjust health drain time rather than drain amount, incase you do a health bar or something, that way it looks smoother)
