setImage() not generating image, please help!

Replied to by Super_Hippo, over 9 years ago:

You are removing the object from the world and then set a new image to it. The object now has indeed this explosion.png image but you don't see the image because the object is no longer in the world.

This is the class of enemy car that the player has to avoid.

This seems to be a little bit misleading because it seems like this car is the one which you can control. I suggest you add a new actor to the world which displays the explosion. As an alternative (because the game ends after the first crash anyways), you can just remove the 'myWorld.removeObject(this);' line. Btw, yo

eror at the font.PLAIN in Greenfoot 3.1.0

Last reply by MrBradley, over 9 years ago:

If you are referring to the font style modifier, you are correct. The new 3.0 version has changes that affect Fonts. Make sure you check the method signatures, you may also be using the parameter in the wrong location with the new changes. Always helpful to post a bit of code as well.

[@danpost] How to center the "camera" in a scrolling world

You should be able to just subtract 3162 from all your coordinate values before you use 'super.act();' (if I am not mistaken).

I probably was mistaken and you need to subtract 2762, not 3162. I was trying to find an easier way to center the town in the viewer. Experimenting with 'setMainActor(dorfzentrum, 0, 0)' followed by 'dorfzentrum.setLocation...' and 'super.act'; then 'setMainActor(maus...'. You would then have to 'addObject(dorfzentrum...' to add the object to the list of scrolling objects in the SWorld object.

'String inputstring' (line 18) is not used for anything. Maybe it has to be 'text=...'?

Holding the mouse down

You will need a Boolean field to track the state of the mouse button: <Code Omitted>Then, in your current code (if the above here is done first), you can utilize the value of 'shooting' (along with your 'firePause' field) to determine when to fire.

I am making a game, which works fine on my personal laptop, but this line of code doesn't compile when on my school computer, receiving the error message "cannot find symbol - variable type" < Code Omitted >

Maybe it works in newer versions of greenfoot because of generics, where the object returned by 'getObjectsInRange' is 'List<InventorySlot>' (this was implemented somewhat recently).

Pause and resume

@danpost: I think the 'pauseAndResume' method replaces and 'pause' and 'resume' methods. This way it should stop the scenario from doing anything when space is pressed until enter is pressed. And if I understood Yunita correctly, it does work now.

Ahh. I missed the 'while' bit. Yes -- that would work; except for the fact that you will not be able to actually Pause the scenario (by way of the greenfoot UI 'Pause' button) when the scenario is actively paused.
