Pong Master - WIP Error Help?

[Dark Mars Software]

Hi Everyone!

I can't seem to get the ball to bounce off the sides of the screen. I have tried

Code: Select all

if ball_x_position > 432
ball_x_position = -ball_x_position
endif

And

Code: Select all

if ball_x_position > 432
ball_x_position = Abs(-ball_x_position)
endif

heres the code:

Code: Select all

fixed by changing the ball's velocity instead of the balls position

any ideas?

[dontmailme]

You need to change the velocity when you detect the wall, not the position!

Try this....

Code: Select all

Removed due to request from author who doesn't want anyone to pirate his game!

To be honest with you, I don't think there will be many programmers in the world who has not written a pong/breakout game. Everytime I have learned a new language the first thig I usually do is code a Pong/Breakout game.

And believe me when I say that no programmer is going to pirate/purloin/copy your code unless they are an absolute beginner!

If you do manage to write an original piece of software which uses techniques that are currently unknown then you should not post it in a forum for everyone to see!

Good Luck with your game

Oh my god, Thank You. I'm now back on track.

Or maybe not

Code: Select all

PrintScores:Needed if StartDrawing()
CloseWindow:Still not fixed

Function PrintScores doesn't work and #PB_Event_CloseWindow in my main event loop doesn't work. Any ideas?

[Dark Mars Software]

Anyone want to help me out?

[Pupil]

You really should read up some more in the manual!! You need to check for the close window event in the little event loop that you have, the last event isn't necessary the close event! Also you probably need 'StartDrawing()'-'EndDrawing()' inside your printscore procedure.

Problems Aarg

I created a function that Pauses and Unpauses my game when the P key is pressed. I managed to get it to pause but, for some reason it woun't unpause when the p key is pressed again. I coded my loop accordingly and have the examinekeyboard() event in the pause loop, so i don't quite understand what i'm doing wrong.

Code: Select all

fixed with code posted by Dare2

Any ideas?

[Dare2]

Without testing anything, just hazarding a guess. This line

Code: Select all

While ~ KeyboardPushed(#PB_Key_P)

uses ~ which is a Bitwise NOT.

Perhaps try something like:

Code: Select all

Repeat
  delay(1)
  ExamineKeyboard()
Until KeyboardPushed(#PB_Key_P)

BTW, in version 4.00 we now have a NOT, so If Not something works.

Hope that was it, if Not , sorry!

[Dark Mars Software]

Well thats what i thought, i imagined that PB had a NOT operator like most programming languages do. Guess it does, atleast NOT yet. As for 4.0, i will be using it once its stable enough.

I have tried to fix this for awhile now and i coun't figure it out.

Problem 1: After a player wins its supposed to show a congrates message and delay a sec so the player can see the win message. The delay happens but, the scores don't switch to the win message. The game simply delays and the message don't get updated when a score reaches 15.

Problem 2:After the win message the game is supposed to reopen the title screen after the initial delay and closing of the game window. Instead it delays, closes the game window, and ends.

Code: Select all

1.Fixed by moving Flip() so that it is the last event that is executed in the game loop.

2.PB Bug. Will be fixed in Next PB 4 Beta.

[Dark Mars Software]

No one has an answer to my problem?

[Pupil]

Maybe you should flip the buffers before the delay..

BTW it's pretty hard to get a grip of what your code does when the posted code isn't indented properly. I have to consentrate really hard to see where a procedure starts, ends etc!!

[Dark Mars Software]

Thanks that worked. BTW 2 things:

1.I am planning on making this open-source

2.I'll find a way to beautify my code.

[Dark Mars Software]

Any idea on a fix for the second problem? I still can't get it to work. I'm using PureBASIC 4.0 Beta 2.

Update:I rechecked the code and it looks fine. I guess this is a PB 4.0 Beta 2 bug.
