Hello,
my Actor does not rebound on the corner. He rebounds with his top on the ceiling, but he jumps through the ceiling at the corners. I would be grateful for your help.
My Code:
An Image:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Feuerlinks here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Feuer extends Actor
{
/**
* Act - do whatever the Feuerlinks wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/

private int vspeed=0;
