Steps for deleting a game objectWould you like to learn how to

What is the process of creating an object that can eliminate itself automatically?

var item = [];
function selfDestruct() {
  this.destroy = () => {
    this = false;
  }
}
function initialization() {
  item[0] = new SelfDestruct();
  item[0].destroy();
}
initialization(); 

Answer №1

If you're looking to release the memory occupied by an object, ensuring that all references are removed is essential. Once done, the garbage collector will take care of the rest.

In your case, since you have a reference stored in an array, you can simply do this: bullet[0] = null

Answer №2

To remove the element from its parent array, you must make changes to that specific array. By passing the parent into the instance, we can instruct the removeSelf method to search for its own instance within the parent array and use splice to remove it.

In addition, I have decided to rename the constructor as Bullet.

var bullets = [];

function Bullet(parent) {
  this.removeSelf = () => {
    const index = parent.indexOf(this);
    parent.splice(index, 1);
  }
}

function setup() {
  bullets[0] = new Bullet(bullets);
  bullets[1] = new Bullet(bullets); // Adding a second instance to the array
  bullets[0].removeSelf();
}

setup(); 
console.log(bullets.length) // Expected output: 1
