Im making a game where you can score points when a bullet hits a monster. I also want to make a scoreboard but I cant use the variable I made for points in the scoreboard class. I already tried to make the variable public but that doesnt work. A video or an example code would be sufficient. Im kinda new to this so keep the code as simple as possible please :)

Please refer to my Value Display Tutorial scenario.

I need the bullet to follow my mouse

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;

Doesn't the rooted method get called when a Villager instance is touched by a RootedCorpse object? Change its image there.

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).

I want an actor to apply a "rooted" status condition when it touches another actor

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>

Call getIntersectingObjects() from a subclass of World

getIntersectingObjects() is protected, so I can not call it from a subclass of World. I was reading the article below... << Link Omitted >> and would love some more context and to know if there is anyway around it.

I do not know what more can be said about accessibility. However, to get "around it", you could add a new method in the class of the actor to call the method and return its results: <Code Omitted>Then call this method from the world subclass.

Dark Maze

Last reply by danpost, over 2 years ago:

One way is demonstrated in my new scenario, Dark Maze Demo

The Light class in the scenario (in the Player class) was modified to allow changing the range of illumination (strength of light). Also, the Scroller class was fitted to support non-scrolling areas along right and bottom edges of the world (a crop method was added).

Trying to make an image gray like an old photo, but I'm stuck. This is the code I have so far, where do I go from here?

Not tested, but I believe if you just add the three color parts together and divide by 3, then use that value for all three parts should be close to what you want: <Code Omitted>
