getOneIntersectingObject

By NatNat, with 2 replies.
Last reply by danpost, over 9 years ago:

The 'getOneIntersectingObject method returns an object reference of type Actor; but, you are trying to assign it to a variable of type Tile -- hence, the error. Just change line 5 to the following so the compiler knows that the returned reference is for an object of type Tile: <Code Omitted>(maybe this is not the problem and generics takes care of this particular thing)

The Counter class has a 'setValue(int)' method each world can use on its timer to set the appropriate initial value. For example, for the first world: <Code Omitted>

Last reply by mehanix, over 9 years ago:

Thank you for the idea!! i've been struggling on this for the past 2 weeks!! With this, I believe my game is ready to be published. Expect to see it soon :) For other people who want to do this who stumble upon this post: The way i fixed this was by having the other worlds besides require a reference to the world they were created in. like this: <Code Omitted> then, in the 2nd world's constructor: <Code Omitted> Finally, when switchi

"fr0". I did not have access to your images; so, I had to use make-shift images and do some code adjustments for testing purposes.

It still blocks and it doesn't show the attFrame even if I press it for some time

What do you mean with block? Does the scenario stop on its own? Do you get an error message? Did you get any output at all?

Now it works. Greenfoot just needed a restart thank you

Need help with health regeneration

By Niskarnix, with 2 replies.
Last reply by Niskarnix, over 9 years ago:

Sorry for the late response. I really appreciate the help. I settled for using if-statements in my batman, sakura, healthbar, and healthbar2 classes to set the condition. Now the fighters can generate health faster if they are 50 or below and generate health slowly if they aren't touching each other and if their health is greater than 50.

NullPointer Exception in GreenfootImage constructor with the new Greenfoot

By Super_Hippo, with 10 replies.
Last reply by nccb, over 9 years ago:

Super_Hippo: Thanks for pointing this out. You're right that it is a bug. I've filed it and fixed it but obviously it won't be fixed until 3.1.1. We don't currently have a timeline for that (we're focusing on a BlueJ release at the moment). As you say, in the mean time you can either change your code to not pass null, write a helper method to use instead, or roll back to 3.0.4 for the time being if this is a major issue across your code base.
