How do you make lives in game maker 8?

I will explain how to make your own lives variable; granting you better control over them.

Create event:

lives_left = 3; //Replace 3 with the lives you start with.

health_left = 100; //Replace 100 with the health you start with.

health_max = 100; //Replace 100 with maximum health available.

lives_max = 3; //Replace this 3 the maximum amount of lives.

Step event:

if(lives_left < .1) { game_end(); /*Replace game_end(); with how your game ends*/ }

if(health_left < .1) { /*How you die goes here*/ }

if(health_left > health_max) { health_left = health_max }

if(lives_left > lives_max) { lives_left = lives_max; }

Whatever event makes you get hurt:

health_left -= .1; //Replace .1 with how much damage you take.

This works by simple math; if you have too many lives, you lose that extra life, to have the maximum amount. If you get hurt, it removes some of your health variable. If you have 0 health left, you lose a life. (Set health back to the maximum when you die though, or you'll infinitely die) If you have 0 lives left, the game ends.

This system allows for healing, by health_left += 20; /*Replace 20 with how much to heal*/, allows you to increase lives max, increase how many lives, and allows you to increase how much health you can have.
