How can I increment a variable without exceeding a maximum value?

Question

I am working on a simple video game program for school and I have created a method where the player gets 15 health points if that method is called. I have to keep the health at

Answer 1

I know this is a school project, but if you wanted to expand your game later on and be able to upgrade your healing power, write the function like so:

public void getHealed(healthPWR) {
    health = Math.min(health + healthPWR, 100);
}

and call out the function:

getHealed(15);
getHealed(25);

...etc...

Furthermore you can create your max HP by creating a variable that is not local to the function. Since I don't know what language you're using, I will not show an example because it might have the wrong syntax.
