Greenfoot is reading setImage() but is not setting the image?

By SloanTheSloth, with 1 reply.
Replied to by danpost, over 8 years ago:

It looks like your instruction pointer is at the 'setImage' line (where it has not executed yet). However, there is a very easy way to accomplish what you are trying: <Code Omitted>

Never mind I may have found a fix by resetting the images assigned to each actor by right clicking and choosing set image.

Can't jump

Omg i found my big mistake.. It's maybe good to share this with others.. I found a platform(ground) image where he stands on and made it transparant( because it had a white background ). But their was still a few inches of transparency above the ground that i didnt cut in my program. So he was just standing on the 'invisble' part of that image. Thanks anyway for the improvement of my code

Tips before attempting a large project?

By alittle_bit, with 1 reply.
Replied to by danpost, over 8 years ago:

If you already know what you want overall, I suggest you create a game plan before writing any codes. For a decent full-fledged project, you could have a header screen, menu world, maps for levels, possibly with scrolling and/or smooth moving -- whatever. I usually start with whatever is first -- like the header screen. Then, move on to maybe the menu with button options for 'play', 'exit', 'credits', and 'controls'. One thing I would not do is create four separate classes for each of the option; but use one class to create the different option actors. Let the menu world retain references

Spawn Objects every second

By Blattstein, with 3 replies.
Last reply by danpost, over 8 years ago:

You could repeat lines 47 and 48 (omitting the 'Fireball' at the beginning of the first line on the repeated lines); or you could enclose those lines in a 'for' loop, the limit of which could be a random value ( maybe '3 + Greenfoot.getRandomNumber(2)' ).
