How can I do it...
I mean something like this to my character class...
if (Greenfoot.mouseClicked("SpeedUp.class")
{
//soldier speed up...
move(5);
}
Well, you cannot use a String for the 'mouseClicked' method; it must either be a reference to an object or 'null'. It should be some type of reference to the button object that is used to speed up the soldier (whether you use 'this' in the button 'act' method, 'getObjects(Button.class).get(0)' on the world object, or a pre-defined field holding a reference to the Button object -- 'speedButton'). There are other alternatives to these, but hopefully, that should be enough to get you going for now.
int speed = 0;
public void act()
{
//this means this object -> the soldier you play
if(Greenfoot.mouseClicked(this))
{
move(speed);
}
//this is only an EXAMPLE:
if(Greenfoot.isKeyDown("a"))
{
speed--;
//whenever the speed should be lower or higher you. Only write speed++; or speed--; .
}
