Hi all

I know it's a bit odd to ask this, because the compiler doesn't ask us to learn ASM but...
I'm starting to learn some ASM and besides read some books, I'm trying to get some examples from <!-- m --><a class="postlink" href="http://stu.pido.us/wiki/retrogames:index">http://stu.pido.us/wiki/retrogames:index</a><!-- m --> and <!-- m --><a class="postlink" href="http://members.fortunecity.com/jonathan6/egghead/id2.html">http://members.fortunecity.com/jonathan ... d/id2.html</a><!-- m -->, but every piece of code I try to compile between ASM and END ASM, end with a compiler error, for instance:

Hi All

After a month of developing, I'm proud to release O-Cman, a Pacman clone for the ZX Spectrum. Their main features are:

- A nearly clone of the original arcade.
- Smooth animations
- Each ghost has its own IA
- Sounds, high score and several minor details regarding the original game.

Things that I think can improve the game (but I'm a bit 'lazy' to do them right now)

- Better IA for all the ghost
- Smooth animation for the eyes (I realize it too late)
- Different graphics for 'eatables' ghosts (I realize it too late too)

I hope you enjoy it as much I enjoyed making it. Please, feel free to send any comments, bugs, etc... I'll be grateful to see them

Cheers

I was trying to keep a list of memory addresses (pointing to tile data) in an array to use as a cheap lookup table. I tried to do something like this:

Using Beepola to add tunes to your ZX BASIC projects is actually pretty easy. Beepola is able to export its players and songs as .TAP files, which you can then merge in with your own code and call from ZX BASIC using standard RANDOMIZE USR calls.

Here's a quick how-to:

1. Make your tune. I can't help much with this bit, but I've successfully managed to integrate the Music Box, Phaser1 and Special FX engines into ZX BASIC, so I surmise they will all work. You can download Beepola from here: http://freestuff.grok.co.uk/beepola/

2. Now you need to compile your tune so that it's useful from ZX BASIC. You do this by selecting 'Compile' from Beepola's 'Tools' menu, which pops up a window with some options. The most important thing here is to make sure you set the player and song to use an area of memory which won't interfere with your own program. I tend to set this high in memory (64000 and up), but bear in mind that each player uses a different amount of memory and you'll also need to leave room for your song data. Each player has a different set of options, but basically it's all up to you here - choose whatever's best for your tune and situation.

3. The easiest way to integrate the song and player is to choose to export from Beepola as a .TAP file. I usually choose the 'code block only' option because you're not going to need the BASIC loader. Once that's saved, you need to load your game AND the player into memory at the same time. It's actually pretty easy to automate all of this using batch files (or their equivalent if you're non-Windows), because .TAP files are remarkably easy to join together. During Dex development, I created a BASIC loader which loaded my game code and the music code and saved that as a .TAP file. Then I used a batch 'make' file like this to build and assemble the game into a single .TAP.

e.g. BASIC LOADER (saved as loader.tap)

Hi all

I'm trying to compile a piece of code but I get the following output:

zxb.exe my_program.bor --org=27000 --heap-size=1024 -t -B -
Traceback (most recent call last):
File "zxb.py", line 312, in <module>

What does it means? I'm using 1.2.8s715 version

Hi all

Sorry to bother you twice in the same day :? I'm falling back to the safe land of BASIC but I'm still struggling with problems. I'm getting an "Unexpected end of file. Compilation failed" error. I'm searching for a lost bracket, lost END IF or similar (another post suggests that could be a lost parenthesis but I can't find any). What others symbols/codes/etc must I look for?

I'm compiling with tha last version and with the following options:
zxb.exe oc_UTF8.bor -S 27000 -t -B -a -o oc_UTF8.tap -O 0 --heap-size=1024

Thanks and regards

Hi all

I'm trying to compile a piece os ASM in BorIDE. The code is:

ASM
[2746 lines of ASM]
END ASM

When I try to compile it, I always have the same error (check image) The point is that no matter if I add or remove lines from the code, the error is always the same and always in the same line (1917) Anybody know if it's a bug? Maybe there are too many lines of code?

Thanks and regards

EDIT: the error is not generated by BorIDE but the zxb.exe compiler, sorry.

Thought I'd post a few shots of the game that I've been working on practically forever. It's 99% done, I'd say. Just need that final push to finish the last few things off.

It's a bog-standard 1982-style 'paint the maze' game in an arcade style. Avoid the monsters or sacrifice some of your bonus to make them vanish for a few seconds. Ten different mazes (played out in a random order, in a variety of colour schemes), high score table, three difficulty levels, yada yada yada.

Hope it looks interesting.



Edit: The game is now out! Grab it from WOS: http://www.worldofspectrum.org/infoseeki...id=0026574

Okay, a new beta release with an *important* fixes :!:

• ! Some operations with arrays leaded to corruption and program crash. Fixed. (thks. to Darkstar)
  
• ! Fixed a print bug discovered by Compiuter (thks). This also simplifies PRINT routines (shorted and slightly faster).
  
• ! Block comments (multiline comments) might crash the compiler and were being incorrectly parsed. Fixed.
  
• + Little assembler optimization under some circumstances.

"Chessboard Attack" is finally out. You can download it from my website or WOS now.
