I think it is the image cycling. Is there a better way to do that, so that it won't slow the program?

Before having the images change with less frequency, comment out line 36 to see if it is actually the animation which is slowing it down.

is there a size limit to sound files?

For loop creating random walls

By MJBelmer, with 3 replies.
Last reply by danpost, almost 10 years ago:

To explain the error, your line 4 it totally messed up. I cannot say whether it is trying to declare a Wall object reference field or an array that holds references to Wall objects. I think that what is on the left of the equal sign is incorrect for either declaration. The ways to declare an array legally are: <Code Omitted>Then, you would assign Wall object to be its elements:

Image transparency and collisions.

Last reply by MJBelmer, almost 10 years ago:

Ahhh so my transparency was fine it's just that Greenfoot still wants to put the image in a box so you can't have a concave area that isn't detected as part of the object. I managed it better though by taking your advice and trimming all extra area that was transparent. Thank you!

How to search for objects and remove them.

By MJBelmer, with 11 replies.
Last reply by danpost, almost 10 years ago:

The one at line 23 should not do anything (it should always return false). You can remove that line. The one at line 9, on the other hand, is placed okay; however, it would be better placed between lines 8 and 9 in the act method code above.

How do I get Alien to re spawn at the top of the screen?

By dlamc, with 3 replies.
Last reply by danpost, almost 10 years ago:

Something I should have mentioned before hand, is that when an alien touches the bottom of the screen two more have to spawn at the top of the screen then move down. How would I do something like that ?

I said you could just switch the two lines. That would be so you can add the new Alien object into the world before loosing the reference to the world, which happens when you remove the current Alien object from the world. Just add two new Alien objects into the world before removing 'this'.

Change background on collision

By DukeFutzwillus, with 6 replies.
Last reply by danpost, almost 10 years ago:

Apparently you have 'static' fields in other classes that will need to be initialized in the MyWorld class as well (to mention one, PortaltoPlanet.nextLevel).

Alternatives to greenfoot

By fejfo, with no replies.

I liked greenfoot mainly for

graphical support
collision detection
input handling

But more I have been doing more advanced things for which greenfoot isn't as good. So are there any good alternatives? I definitely want:

graphical support
collision detection (preferably even polygon collides)
a better IDEA

And I would like:

networking support
3D and full screen support
input handling

I'm probably willing to learn a new language. But I don't want something that has a big complex interface (like Unity). I still want control over basic things (like movement). any suggestions?
