Instead, we'll declare a variable called
fruit_remaining, and set it equal to the length of the fruit array
after we've loaded all our fruit.
add_fruit(20, 20) ;
add_fruit(-20, 220) ;
add_fruit(-50, 320) ;
add_fruit(290, 170) ;
add_fruit(390, 100) ;
add_fruit(200, -60) ;
var fruit_remaining = fruit.length;
Then, every time a bad thing happens to some fruit, we'll reduce it by one.
function make_bad_thing_happen_to_fruit (berry) {
if (berry.costume < 5) {
fruit_remaining--;
berry.animation_continuous = false;
berry.animation_final_costume = 9;
berry.costume = 5;
berry.animation_rate = 8;
}
}
