How to change my world with actors

By Petr, with 9 replies.
Last reply by danpost, over 6 years ago:

Now your addedToWorld method has too many parameters. So, it does not have the correct method signature to be automatically called by greenfoot when the actor is added to the world. Hence, boardImage is not assigned any GreenfootImage object and remains containing a null value. I, however, do not see anything in the code that would require the need to know what type of world the actor is in. If all you need is the width of the world: <Code Omitted>would be sufficient:

private final int GRAVITY = 1; //gravity. to make it fall. Final int so it cant be changed unless you hard code it. private int velocity; //optional. makes it fall faster over time. makes it more realistic. public void fall() //fall. method for gravity to work { setLocation(getX(), getY() + velocity); //makes character fall depending on velocity if (isOnSolidGround()) //checks if boolean isOnSolidGround() is true { velocity = 0; //sets velocity to 0 if its on solid ground so the character doesnt fall through objects

Score counter isn't working

By annika.g, with 5 replies.
Last reply by danpost, over 6 years ago:

I do not see anywhere where the score is upped when hitting a ghost. Also, I do not see from where the hitBlauerGeist method is being called. Q: in what class is the 19-line code set just given above? and why is there a score field there when you already have one in the Counter1 class?
