What ever works . But keep in mind, Pong isn't exactly a CPU hungry game so optimization isn't important. It's good for practice though. I don't use PUT (or anything directly linked to memory adresses) because I don't know how, but I've managed to do without such pretty well.

Weeeeeeeeeeeelllllllllllllllll......... The thing is, I NEVER use PSET in my program, I use PUT...

And I've tried SUBs, but I mainly use them for useful functions. Like faster CLSs and PSETS. I call them XPSET and XCLS

The theres also XLEFT, XRIGHT, XUP, XDOWN. But those are recent. I use them for the arrow keys.

Uh.. where you normaly print the graphics.
It's a good idea to take advantage of modular programming. By that I mean you have work done in components of the program (subroutines) so editing and debugging is MUCH easier.
Code clarity may seem tedious and unnecasary, but trust me, it pays off.
If you don't believe me, go code a 1k program in TI-BASIC, leave it for at least a week, and go back. I had to delete my best because of obscurity (WHAT DOES (G=4)G MEAN!? ).

I won't tell you where to exactly put code, because you will (and should) develope your own style. And me telling you what to put where doesn't help you become familiar with your program.

Where do I put the PSET?

Here, try this:

... 'normal code
PSET (X,Y)
PSET (U,V),0 'turns old image off
LET U=X
LET V=Y
...

That makes you pong ball move very quickly while using little memory.
MAKE SURE TO SET U AND V TO X AND Y AFTER PSET!
Good luck. That was my first program.

It took me a few tries, but I managed to beat it. Not bad. Faster response and movement for the paddle would be nice, but then that would take away the challenge factor.

You can load bmp files in QB. All you need to know is how to load a file and understand the bmp file structure. But if you don't have the time for that then there are libraries you can use that will do it for you. DirectQB and FutureLib are good ones. You can find them, along with others, here.

Cool

So is it a good game? It's my first one, and I would really appreciate some pointers.

Oh, and how do you use .bmp files in your game? Is it possible?

Hey, wait a second, I just checked the code with my copy, and it has a HUGE chunk missing...

It turns out that this forum cuts off the code... Here, let me upload it to a site and link to it here...

Here, go download it and see if it works -

You must have pasted the wrong version of the code or something. Look up at your first post with the code. There is no check for the down arrow.

I don't know why that happens, as it works fine for me. And the controls are the up and down arrow keys.

And how are you running the code? Did you paste it directly in the DOS window? Because that doesn't always work right. Try pasting it into Notepad and saving it as a .bas file.

Oh, well, then I really don't know. Can I upload the EXE file?

4.5

Windows XP Professional
Pentium M, 1.7ghz

It runs for the first second, but when the ball goes off the screen it crashes the program.

Also, what are the controls? All I can find in the code is a reference to one keypress. How can you play the game with only one key?
