help inverting a players movement keys
edit!!!:
i figured out how to invert the movement but now the player moves WAY too fast while inverted heres my code:public class main extends Actor
{
int speed=-2;
/**
* Act - do whatever the main wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
left();
right();
up();
down();
}
public void left() {
if (Greenfoot.isKeyDown("a")){
setLocation(getX()+speed,getY());
}
}
public void right() {
if (Greenfoot.isKeyDown("d")){
setLocation(getX()-speed,getY());
}
}
public void up() {
if (Greenfoot.isKeyDown("w")){
setLocation(getX(),getY()+speed);
}
}
public void down() {
if (Greenfoot.isKeyDown("s")){
setLocation(getX(),getY()-speed);
}
}
}
if (isTouching(funnyinvert.class)) {
invert=invert+1;
}
}
public void invert(){
if (invert==1||invert==3||invert==5){
speed=speed+4;
}
if (invert==2||invert==4){
speed=speed-4;
}
}

private void move() {
int dx = 0, dy = 0;
