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? :)

Removing an object and adding it again at the same place.
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
try this:
public void readdObject() {
//saving the old objects coordinates in this integer variables;
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.
is the class your putting this method in an actor or a world
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);
