I know about adding anobject and removing one, but I want an object to be added at the same position it was removed. How do I go about doing this? :)

do you want to remove one & add one object because you could do (in the world)
?

oldX=Object.getx();
oldY=Object.gety();
removeObject(Object);
//condition to add object again
add Object(Object,oldX,oldY);

Having a bit of trouble implementing the code. The Object I want to remove is called "SneakLeft". Also having trouble with what oldX and Y is and what I should be replacing it with.

oldX and oldY are just names for the saved coordanates of the sneakleft so you can put it back at the same place

public void readdObject() {

    int objectsX;
    int objectsY;
    //the part where you find the object;
    Actor actor = getOneObjectAtOffset(Actor.class, 0, 0); //could also be other classes or methods you are using now. Just leave yours;
    //give the values of the objects coordinates to the variables objectsX and objectsY;
    objectsX = actor.getX();
    objectsY = actor.getY();
    getWorld().removeObject(actor);//remove the actor;
    getWorld().addObject(new Actor(), objectsX, objectsY);//add the new Actor. Probably Actor is the wrong type. Just add the type you want;
}

Here's what I got: public void readdObject() { //saving the old objects coordinates in this integer variables; int objectsX; int objectsY; //the part where you find the object; SneakLeft sneakleft = getOneObjectAtOffset(SneakLeft.class, 0, 0); //could also be other classes or methods you are using now. Just leave yours; //give the values of the objects coordinates to the variables objectsX and objectsY; objectsX = sneakleft.getX(); objectsY = sneakleft.getY(); getWorld().removeObject(sneakleft);//remove the actor; getWorld().addObject(new SneakLeft(), objectsX, objectsY);//add the new Actor. Probably Actor is the wrong type. Just add the type you want; } I'm getting a "cannot find symbol- method getOneObjectAtOffset(java.lang.Class<SneakLeft>,int,int)" error when compiling. Thanks for all you guys' help btw.

This discussion is getting rather confusing. Hopefully, I can make things a little bit clearer. In order to add an object back to the world at the same location it was removed from, with code in the world class: you will need to save the object and both the x and y coordinates of the object before removing it.

// world class variables (or fields)
SneakLeft sneakleft; // to hold the object
int sneakleftX, sneakleftY; // to hold the removal location of the object
// when creating SneakLeft object (in constructor of world)
sneakleft = new SneakLeft();
addObject(sneakleft, whateverX, whateverY);
// when removing 'sneakleft'
sneakleftX = sneakleft.getX();
sneakleftY = sneakleft.getY();
removeObject(sneakleft);
// when re-adding 'sneakleft'
addObject(sneakleft, sneakleftX, sneakleftY);
