How do I make an actor turn into a frog upon contact with another actor

i have two actors under the same superclass "Pedestrian". One of the actors is called villager and I want him to turn into a frog upon contact with the other actor called "EvilWitch". << Codes Omitted >>

Looks like you have code in the Villager class to do just that. Only problem is that if contact with EvilWitch is more than one act step, which is most probably the case, then the image will be made smaller multiple times; and, at some point, it will try to make it a size that is zero or less, causing an error. You need a way to check whether the a

Please refer to my Value Display Tutorial scenario.

Could you maybe give an example? right now I have this. The bullet only spawns at the coordinates of the mouse (a kogel means a bullet). << Code Omitted >>

I think all you need do is: <Code Omitted>Note that if your bullet moves too slow (less than maybe 5 pixels per move), the aiming will not be accurate -- maybe so inaccurate that it looks totally off. For the extreme example, if moving only 1 pixel per move, the movement will either be horizontal or vertical;

The Greenfoot.start() method has a void return type. You cannot reference a void or compare it with anything. Also, the equal comparison operator is a double equal sign ( == ), not a single one ( = ).

The condition here will ALWAYS be true (if you have a class called Player).

do you have a good and easy idea for a game that i can make for school

Avoiders are the easiest type to create. Adding some type of shielding might be an easy idea. Or, you could add shooting ability to the player, which would be a slight step up. You could continue to add other options later, which again will be stepping up.

i<Code Omitted>

This code, in your Fighter_Kogel class, should be removed if you want the instances to move and get removed at edges like a Kogel instance is programmed to do. As an alternative, you could change it to: <Code Omitted>
