Java: Get() and Set() return default values

[_Art3mis_]

After some days trying out and debugging our program we found the fault, but sadly not the answer

 

Here is what we have got:

 

We fired up the programm and noted down the X, Y and Accelaration/DeltaX and DeltaY.

After the ball hits the paddle, the deltaX value gets inverted for one instance but gets reseted on the next (and stays there until next collision).

 

Here is the Console output:

run:Entering drawFrame(); X: 1030,000000    Y: 722,000000DX: 20   DY: 20 X: 1050,000000    Y: 742,000000DX: 20   DY: 20 X: 1070,000000    Y: 762,000000DX: 20   DY: 20 X: 1090,000000    Y: 782,000000DX: 20   DY: 20 X: 1110,000000    Y: 802,000000DX: 20   DY: 20 X: 1130,000000    Y: 822,000000DX: 20   DY: 20 X: 1150,000000    Y: 842,000000DX: 20   DY: 20Collision up X: 1170,000000    Y: 862,000000DX: 20   DY: -20 X: 1190,000000    Y: 842,000000DX: 20   DY: 20

Thank you for all your previous help

prepare your coffee

 

the only thing i can suggest is, seeing that you're not used to code the OOP way, to prepare a list of all the classes you will need and the methods that you will need them to have, before actually diving into code

 

Sadly we have to use the exact classes the professor gave us

[Ciccioo]

did you apply any of the tips that we gave you?

the code looks quite... similar... to how it was before this discussion

I am sorry for the abondanation (right?), I'll answer tomorrow

Again, we had no time to program

 

So many exams...

I hope we can get back to normal as soon as possible..

 

However, we made some progress in school last week, here is the newest version: http://pastebin.com/7UwERL9n (hope it's the right version)
