I think you're trying to run NTSC carts in a PAL system.

[Odd Activision Patch]

Dude, I so want one.     

 

I don't know why you would... the letter they sent along with it wasn't very nice either.

 

 

I suppose it's asking a bit much to hope that was a form letter.

LOL. TELL me that is photoshopped!

Nope. I'll attach my source code for poking/"omgwtfishedoingthere"ing.

Well, seeing as all the upgrades to BB completely broke my program, I get to do a complete rewrite! The code was getting pretty messy anyway, so I should clean some of the spaghetti up.

[Alpha 0.35 Official Release]

Now I have to remove all these hacks to get it to work in 0.2... upgrading to vanilla 0.35 really broke my program badly.

[Current snapshot of Stella debugger]

WOW! That could really help me figure out why my Batari Basic games don't work!

[Can somebody post the bare minimum to read paddle?]

Doesn't work either. Here's my code.

breakout.txt

[Can somebody post the bare minimum to read paddle?]

The ball code I'm using makes the ball appear in Stella but not in Z26, and in neither does the ball move at all.

 

ballinit
 n = rand
 if n < 63 then t = 1 && u = 1
 if n < 127 && n > 63 then t = 1 && u = 0
 if n < 191 && n > 127 then t = 0 && u = 1
 if n < 255 && n > 191 then t = 0 && u = 0
 goto ballmove

ballmove
 if m = 0 then goto 70
 if t = 1 then ballx = ballx + 1
 if t = 0 then ballx = ballx - 1
 if u = 1 then bally = bally + 1
 if u = 0 then bally = bally - 1
goto 17

 

Why won't my ball move? M is set to 1 upon pressing fire.

[Batari BASIC and naysaying]

The games will get better as Batari BASIC improves, but there are still plenty of available functions that can your software a more polished look.  I'm really surprised at what the 2600 can do, offering large (well, long, anyway) sprites and even the ability to stretch them out to double, even triple their original size!  Playing with the TIA registers made me feel like a kid in a blocky candy store!

TIA registers are fun! You can make loads of game modes with them if you want to go the Space Invaders 116-in-1 route.

[Can somebody post the bare minimum to read paddle?]

I noticed the file size shrinks each time you upload a new one...

 

Does the ball have only one thickness?

[Can somebody post the bare minimum to read paddle?]

Yes, I'm using Batari's paddle kernel. I made the line that jumps to loading a level jump to the next line, so there is no playfield at all.

[Can somebody post the bare minimum to read paddle?]

Well then the ball doesn't work either.

 

I have the following for ball code:

 

 ballx = 70
 bally = 50
 ballheight = 4

 

I inserted that before my drawscreen. The playfield obviously has a color, so I don't know why it won't show up.

[Can somebody post the bare minimum to read paddle?]

What variable sets the ball's color?

[Can somebody post the bare minimum to read paddle?]

Still a minor problem with display, now ALL pfpixel scanline breaks are 1 pixel too high! Paddle works though, thanks for the kernel.

 

For everyone's information, when drawing a playfield with PF0=128, the left boundary is 31 and the right is 151, giving you a 120 pixel playfield.

 

Also, what do I have to do to enable the ball? Just give it an X, Y, and height? I'm assuming a height of 0 disables it.

Well, I do have 4 sets or so of these...

[Can somebody post the bare minimum to read paddle?]

That's odd... the left 20 pixels or so are one pixel lower than the rest of the screen!?

[Can somebody post the bare minimum to read paddle?]

EDIT: double post

[Can somebody post the bare minimum to read paddle?]

Perhaps someone who knows paddles better than I do may know what the problem is. Here's the kernel - note that you lose missile 0, and you must have a dim paddle0=missile0x at the start of your program. The return value from the paddle will be in the variable paddle0, and it returns 0-88, so you may need to multiply by two and do some bounds checking if you are using it for a horizontal position.

Thank you! Now I can get to work getting paddle support for better control

 

If Z is currently player0x, then I have to make paddle0 equal Z * 2 for my rectangle's position?

 

17 player0x = z
18 player1x = o
19 player0y = y
20 player1y = p
21 z = paddle0 * 2

I'm wasting enough scanlines as it is

 

If you want to get into a scanline wasting war...

[Bug Report Thread]

So it'll have a ball-and-paddle kernel? That's really what I need for my game, ball support and paddle support. I haven't done any playtesting of it because I can't get missiles to work properly.

[label proposal]

They're in some cashflow trouble, so Infotari sues everything they see. Besides, Paddle Battle sounds a lot cooler than Breakout

[Bug Report Thread]

Alpha 0.3 will have paddles right?

[label proposal]

Here's a mockup I made for Paddle Battle.

[label proposal]

Yes, we can use "game program" in our labels.
