Just curious, why does Greenfoot.setLocation(getX(), getY()+1) make it go down?

Actually, I'm curious what you expect this to do? (Did you mean you would expect it to cause an actor to move up)?

Yes, I thought that adding to the 'y' variable would make it move up and vice versa.

Why is my Greenfoot not compiling and crashing often?

I also noticed the problem of Greenfoot sometimes not compiling. When this happens I close Greenfoot then reopen it and it compiles. As for failing to save to disk, this only happens to me when I try saving to a network and is disconnected for the moment but is usually connected.

Player Actor facing mouse similar to Hotline Miami

but the part I'm stuck on is the actor facing the mouse. If the mouse is stationary, the actor stops turning to face it. Is there a way to get the actor to always face the mouse regardless?

So to answer your question the reason it happens is because YOU added in an if to purposely make it happen, all this if does is make that happen. The if to remove is the one mentioned above. <Code Omitted> when I removed this if it worked fine.

Make an unbounded world and just add all. Then you need a way to scroll down, so move all objects upwards. You can also change the scoreboard, so more results are fitting on the screen.

I guess so, but I was looking for something like the way "bourne" did it, which I guess I can just look at his code.

Btw, for testing purposes, you can check the highscore table in Greenfoot, too. Press Ctrl+Shift+P to change to name, run the scenario to get the score for this "player", then change the name again and so on. This way, you can fill the highscore table offline

The array could look like this: <Code Omitted> Then you can have an int field. Whenever the animation should run (when the right key is pressed), increase this field and set the image: <Code Omitted>

How to set last image of an animation.

Last reply by Super_Hippo, over 9 years ago:

The problem is that the actor is moving more than one cell each act cycle and he moves all together without checking in between if he reached the platform. To make it move step by step and check between every step, you could change the falling method to this:

Question about the World's showText() method

By nelutux, with 2 replies.
Last reply by davmac, over 9 years ago:

I guess you mean you want the text shown to disappear after a few seconds. Did you try reading the documentation? :)

Show some text centred at the given position in the world. The text will be displayed in front of any actors. Any previous text shown at the same location will first be removed. Parameters: text - The text to display; can be null to show no text x - X-coordinate of the text y - Y-coordinate of the text

So: after a few seconds, call showText again with the same co-ordinates but null for the text (or the empty string as s

So for the problem with 'import', I found that my mistake was that I rewrote 'import greenfoot', which was originally at the top of my code. I put the content in the code I showed you and I placed it under the original 'import greenfoot' and the code worked. Thanks again for your help.

timer

By gergoa12, with 1 reply.
Replied to by Super_Hippo, over 9 years ago:

Create an int field which you can use as a timer: <Code Omitted>Whenever you shoot, set the timer to some value (3 seconds is about 170 I guess). <Code Omitted>Each act cycle, you reduce the value by 1 if it isn't 0: <Code Omitted>Before shooting, check if the shotTimer is 0, you can also use it right after the last line, so: <Code Omitted>
