oh note: The there is text that it already displays on the timer when it is over however I want to change it to activate a separate gif to appear on screen

Use a separate actor to run the gif. You can adjust lines 200 and 201 to create the actor and put it in the world (before the possibility of removing the timer itself from the world.

I'm making a shooter's game and I want the bullet to disappear when I hit a bad guy. But the code for the collision doesn't seem to work with my if at edge remove the object. here's the code. << Code Omitted >>

Between shot and checkEdge calls in act, place the following line: <Code Omitted>Btw, the return statements in your given code are kind of pointlessly placed at the end of the methods. Methods are automatically returned from when the end is reached.

Are you sure? Pac-Man is a fantastic game. It is not really easy for a beginner to program though. But possible in three month if you like programming and want to invest some time into it. Space Invaders seems more like a one hour project.

How do I Resize my backround

So basically im new to Greenfoot, and I want to learn how to resize my backround so it isnt all tiles. Help !

The World constructor, which is called by the first line in your World subclass constructor beginning with the word super, specifies the cell size. Do not let any tiled background image fool you into believing that the world is still tiled when giving a cell size of 1.

setPaintOrder(street.class, stripes.class, player.class);

I am quite sure you meant: setPaintOrder(player.class, stripes.class, street.class); Also, the super constructor call would need to be called prior to this line in that constructor.

How do I make an actor "fall" where there is a line?

any thoughts on the whole code itself because it does not work.

It would be difficult to give any advice without knowing exactly what you are dealing with. A detailed explanation of how you want the ball to behave would be a start. However, usually, a move would be made before checking that it is okay and retracted if found not to be.

Can you help me?

To be "realistic", you would change the angle based on its current rotation (direction) and the angle of the surface on which it bounces.

The first method results in a syntax error and the 2nd method prints this to the log: java.lang.ClassCastException: class java.util.Arrays$ArrayList cannot be cast to class java.util.Vector (java.util.Arrays$ArrayList and java.util.Vector are in module java.base of loader 'bootstrap') any alternatives?

Alternative has already been provided:

There may be a conversion problem which would then require you to iterate through the array (from parameter argument) and place the triangles into the vector via a loop.
