The rotation of a ball has nothing to do with the direction the ball travels. So turning upon collision or setting its initial rotation should not influence the movement of the ball. Your collision method has yet to be executed as it still needs to be called from somewhere. That being said, it is no wonder that you are having trouble with the bouncing as the value of 'isFall' is never changed (nowhere is it being set back to true and, since the collision method is not currently executing, it is never set to false). All your actor will do is fall.

There are only hardware limitations as to what is (should be) possible. Create the menu World subclass and add the button Actor objects that the clicks are detected on (to start).

Okay, I will do that. Thank you so much!

I would think it's possible, since it's possible with java and that's what Greenfoot is, the question is How? Maybe this will help: Custom Networking

Okay. First, let me correct a typo in what is now your line 25 above, which should be: <Code Omitted>Now, your world constructor should begin like this: <Code Omitted>You may or may not have some parameters between the parenthesis. Curiously, I am not sure why you named the class that creates objects that represent lives 'HealthBar'.

See here. Instead of changing to Level2 change to GameOver, or instead of adding objects for new level, add in game over image/actor.

See here.

That depends on what your levels are (different world, just remove objects and place new ones, etc.). If your score to switch levels is 100 and you have an int field named "score" holding the current score, then you can use those in an if statement to change the level.

Alright. i gonna try to programm this tommorow.

Well my code is pretty short, and there is no other P, but it doesn't matter anymore, it works Thanks!

hi danpost thank you very much got it to read the file

Vielen vielen Dank. Habe es dank deiner Hilfe nun geschafft. :)

The 'delay' method of the Greenfoot class suspends the execution for the specified number of act steps (like a temporary pausing of the scenario). Jumping is the rising and falling of an object over several act steps. You need to code it for what needs done during any one individual act step. How you implement the coding is up to you (whether you want to limit the height and just control the direction, like floating up and down, or you want to make it more realistic by applying a downward acceleration to the vertical speed, for the effect of gravity. Either way, or whichever way you choo

The code is saying "if the rock is touching the boat, remove the boat". Exactly that is what is happening. I am not sure if the rock should move at all, but maybe you should remove the rock and not the boat. Usually, I would say the boat touches the rock and not the other way around, so you could place the code in your boat class and check for intersections with rocks.
