Greenfoot 3D

@davmac & danpost: sorry, i didn't see that :/ :) @erdelf: the latest greenfoot 3d .jar uses(I downloaded the jar, and looked up the code..) Like you see, you can pass a float in here :/ Furthermore, the incompatible types java exception always shows the types that caused this exception, so i'm not sure what you mean. Can you mail me the console/error log pls?

Try something rotateX(1.2f) - this will surely work. The incompatible types isn't the 'wrong parameter' error i suggested - your error happens because earth.getRotation() can't be cast to float (or?).

Sorry, again. It appears that I do not know what I am saying, because I am not familiar with the method you are using and exactly what it does. But I think it should work if you drop the 'earth =' part. However, you may have to put parenthesis around '(Actor3D)earth'

@GreenHouse, the cast doesnt matter, if i dont cast it, i get the same error. and why should the cast of a float to a float doesnt work`? Edit: still doesnt work @danpost, the paranthesis u suggested would destroy the reason i used the cast Actor3d here

earth = earth.rotateX(0.2f); tell me if this line works for you; if yes then earth = earth.rotateX(earth.getRotation()); will also work

Why does the 'rotateX' method return 'this' back to the calling method? The calling method must already have a reference to 'this' object just to call the method.

Yeah :D good question ;) the return is for something like this: earth.rotateX(0.2f).rotateY(0.1f).rotateZ(0.3f); Otherwise, you need to write earth.rotateX(0.2f); earth.rotateY(0.1f); earth.rotateZ(0.3f); which is the same, but a bit longer and not so cool to read :)

ur line earth = earth.rotateX(0.2f); doesnt work. idk why same error

Or put the whole expression in parenthesis with '(Earth)' in front. But, since you are only using one method (not stringing them), removing 'earth =' would be the way to go. Actually, you should never need 'earth ='; no matter what.
