I'm making an infinite runner type game and I want one of my enemies (when it's created) to swoop down in a sort of U motion where it'll hit the player if they don't react quick enough once the enemy (bat) leaves the screen it'll be destroyed and created again once certain requirements are met . The path will be the same each time so I don't need anything to do with AI. Unfortunately I'm only in grade 10 so calculus makes no sense to me and neither does the pathfinding libgdx documentation. I either need something similar to this (But written for libgdx) or some way to get a box2d body to move in an exact way.

My game is structured like this:

in Bat.java:

public class Bat extends Sprite {

private World world;


public Bat(GameScreen screen) {

    this.world = screen.getWorld();
}

In GameScreen.Java

public class GameScreen implements Screen {

private Bat bat = new Bat(this);

public World getWorld(){
    return world;
}
