Question

I am trying to create a canvas game using the proccessing.js library.

I use an array to hold all my objects.

class blah{
    ...
    void delete(){
       // this.remove ???
    }
}

blah myArray = [];
myArray.push(new blah());

Is there a way I can create a delete function inside that class so that when the element is deleted it is removed from the array? I have thought of a workaround like passing as an argument the element’s position in the array. Isn’t there a direct way to delete it without passing any argument?

The workaround I told above:

void delete(int i){
  myArray.splice(i,1);
}

You should be able to find the instance with indexOf:

void delete() {
    int index = myArray.indexOf(this);

    if (index > -1) {
        myArray.splice(index, 1);
    }
}
