(1) you should avoid using 'static' variables and method unless you need to retain a value during a scenario reset (like for a session high score, for example); (2) lines 15 and 121 are problems in that the will be set to values prematurely; these line are set when the object of their respective classes are created and do not automatically update; remove those lines and get the values from within the act method when needed; It would be easier to check for
Actor
object clicks in your
MyWorld act
method. You could start with the following classes:

Hippo is correct about what the line should be. You should have been getting an error without the correction since you are not using a "ka0.png" image.
fatcat scenario - issue of being unable to inherit the value of a public variable in subclass MyCat, inside the walkLeft and walkRight method call parenthesis

So, in the super class MyCat, there should be 10 instead of 'int distance'?
There should be something that has a specific value. It could be a literal constant (like '10' is) or it could be a variable (with a pre-assigned value) or it could be a method call that returns a value of the appropriate type (int, in your case) or it could be an expression that evaluates to a value of that type. At any rate, you supply the distance that you want it to move.
non static method cannot be referenced from a static context.

The is a series of problems with how you are trying to add worms into the world during game-play. First, in the
wormToevoegen
method, you have this: <Code Omitted>Line 2 creates a variable to hold a
Worm
object; then, line 3 assigns its value to itself (more of a fact than a command) -- its value remains
null
. Line 4 then tries to call method on a non-existent (null) worm. Let us now assume you had created a worm and assigned it t

Mario not dying when touching object
By Starvader, with 1 reply.
Replied to by danpost, about 7 years ago:
A few things to consider:
only check collision between two object in one class -- not in both (I would put it all in the Mario class);
only check collision immediately after each move of the actor;
keep horizontal and vertical movement code separate (knowing which move caused a collision will tell you the orientation of the colliding actors);
you may want to dispense with the array of enemies in your world class; I doubt very much that there is a need for it
Please give your reason for the array if you feel you need it. T
