Do you mean GIFs?

A GIF image set already has set display times for its images; so, it cannot be that. This is a duplicate discussion which should be ignored.

Need help with timer

By Cmo, with 2 replies.
Last reply by danpost, about 1 hour ago:

The first line says that the timer field should count down from zero. No wonder it does not work. Also, in your timer method, why would you want to possibly subtract two from the timer field in one act step? Change the timer method to this: <Code Omitted>You probably also want to change how the showTimer method displays the timer field value, maybe using something like this:

It didn't work. I think it might be because my method to make the eggs disappear is in my actor predator.

If you are using getWorld().removeObject(...) to remove the Egg objects one at a time, then the provided code should work.

I honestly do not know. I have no idea what you are working with. Did you try anything? Show some attempted code. Then, I might get an idea.

You have yet to set the new MyWorld object active using the setWorld method of the Greenfoot class. You may want to consider using a local variable inside the if block instead of a field for the new world. World objects, mainly due to the size of their images, take up a lot of memory and with multiple icons creating and retaining a world (the

i dont get what you mean

I mean that you add a boolean field to those classes to track the state of the firing key. For example, if "space"is used: <Code Omitted>Any time this field is not equal to what the isKeyDown method returns, then the keys state has changed and you can update the value of the field: <Code Omitted>Upon updating, you want to know if the change was for pressing or releasing the key. So, at this point, you ask:

Turning off Greenfoot auto-compile: please...

By LaurentB, with no replies.

Hi, I know that the question was already asked several times in this fourm: 'how to turn off auto-compile' And I know the usual answer: it's not possible and auto-compile is not a problem because you still can edit code when compiling. But unfortunately, that's not the case... Yesterday, in my CS lesson, I was typing 'live' code showing an exercice solution to my students. And it was a nightmare. After typing a few characters the editor paused, saved the code and compiled it. I was blocked during about 5-10 seconds each time. Apparently there are situation where auto-compile makes real trouble (old computer with old OS with slow network (for instance when project is saved on shared drive over network)). In those situations, the possibility to disable auto-compile and launch manually compilation (CTRL + K) would be very usefull! Greenfoot is great but since we passed to the 3.1 version, auto-compile slows everything and makes the use of the editor a really bad experience. Thanks a lot for your precious work Laurent (a teacher using for years Greenfoot with his students)

Game ends after shooting one enemy

Replied to by danpost, about 11 hours ago:

Move line 26 to the constructor (no need in continuous setting the same rotation to the actor). For line 27, use this: <Code Omitted>This is so that if detectCollisionremoves the actor from the world, isAtEdge won't error. The added statement uses a return statement to forces an immediate stop to the execution of the method if the actor is no longer in the world.

Embedding scenarios in other web pages

By davmac, with no replies.

If you have a blog or other website, you may have wanted to be able to embed a Greenfoot scenario in it. Up until now, that has only been possible with the legacy applet version of scenarios. But now, we have added the ability to embed HTML5 scenarios in other web sites! You'll notice a new "embed" link beneath each scenario. Clicking this will open a dialog with a short snipper of HTML code that you can copy into your own web page. An embedded version of the scenario will not have the controls (run / pause / reset / speed slider) visible, and will auto-run when it loads. The scenario itself is still hosted on this site, greenfoot.org, and is displayed in the other page as an IFrame. If there any questions or comments, please feel free to post here!
