Sorry your browser is not supported!

So i just started with the GDK. My C++ skill level is low. Though i have a strong skills in BASIC.

I have a few questions. So if you'll be willing, i'd be most grateful.

I have set my screen size to 1024,768.
I have a paddle, you can move it left and right.

When i move it right it carries on and disapears. The control for it only allows movement if the paddles x variable is < 1024-50 ( the paddle is 50 ). But the right wall does not seem to be at 1024! Do i need to set a pixelsize or something? Or is there some other reason.

Also, as i am new to this language, if you have any comments on how to improve my code, or if i should be doing something a differant way, please TELL ME!!

// the main entry point for the application is this function
void DarkGDK ( void )
{

//Game window Settings
dbSetWindowSize (1024,768);
dbSetWindowTitle ("My First Dark GDK Game");
dbSetWindowPosition (30,40);

// turn on sync rate and set maximum rate to 60 fps
dbSyncOn ( );
dbSyncRate ( 60 );
dbPositionCamera (camx,camy,camz);

// our main loop
while ( LoopGDK ( ) )

//Do what needs doing
ball ();

drawgameobjects();
// update the screen
dbSync ( );

//Bad console habits die hard!!!
//system ("PAUSE");

// return back to windows
return;
}

Use dbSetDisplayMode(1024, 768, 32) instead. dbSetWindowSize just resizes the window, and does not change the actual resolution.

Also:

Use '=' for assignment, and '==' for comparision.

ballflag = 3;
if(ballflag == 4) { ... }

This, 'if(ballflag = 3) { ... }' will set ballflag to 3 instead of checking it, and that statement will always be true.

And in your code for checking to see if you are to far right you have this:



You should have this:


also use code tags

Thanks folks, your tips have made it work.

I'll be back with more questions soon i'm sure.

I have a new question, why does my sky box not load? I have tried everything, and it does not work!!!!

heres the complete programme...

and heres the skybox code...



If i need to do something else or have just messed it up please let me know...it's driving me mad!!!

Thanks folks...UNSEEN

Solved it. I had the Scale values WAy too high!! i am now using 10.
