« on: January 05, 2012, 05:09:49 pm »

Vote for it ^ or post a suggestion here.

I' ve made a temporary project home page, but there's not really a lot to see there yet.
No mini competition please, teamwork is better

Details
Language: Axe
Platform: TI 83+

Things we'll need to do/make
Draw the sprites. saintrunner
A save file format. yrinfish
A level generator.
A Tilemapper.
Some sort of AI.
Crafting system.

People on it (AFAIK)
annoyingcalc
saintrunner
Hayleia (your avatar is really cool btw)
epic7
Blue Raven
yrinfish

Computer Programming / File reading with c/c++

« on: August 18, 2011, 03:09:10 am »

I want to be able to do this on a file:

Code: [Select]

myChar = getTheNthCharOrSomething(9);
that for example in pseudo-code, getTheNthCharOrSomething() is this:

Code: [Select]

char getTheNthCharOrSomething(where) {
    return file.charAt(where);
}

file is a global var.

Computer Projects and Ideas / Designing Happy - OOP

« on: July 16, 2011, 05:25:10 am »

Ok, I'm trying to add OOP to Happy.
I only have a small problem:

Where do I place te objects, and how big?

It is simple with objects like this:

Code: [Select]

type point[2] {
    ubyte x;
    ubyte y;
}

// And in the program or global declarations:

point lol;

I can place this with the other vars after the code, and I know I need 2 bytes of space

But even this approach gives problems:
For example, how do I give it initial values?

Amd when using the stack, How do I know the amount of space left?

And this gives even more problems:

Code: [Select]

type string[] { // Yup, no native support
    ubyte[] value;
    
    empty create(ubyte[] in) { // empty is a subroutine type
        // Loop and copy the string
    }
}

This one doesn't make sense, because we have the same data twice in RAM.

Code: [Select]

type enemy[10] {
    ubyte x;
    ubyte y;
    ubyte[8] sprite; // The monochtome sprite data

    empty move(sbyte dx, sbyte dy) {
        x = x + dx;
        y = y + dy; // update the pos
    }
}

To make it short:
1. Happy doesn't always know how big it is
2. How can initial values be set?
3. How do I stop the program from corrupting things in RAM, with a ever-growing stack?

Minecraft Discussion / Omnimaga minecraft server

« on: June 18, 2011, 05:21:25 am »

What about an omnimaga minecraft server??

We have to think about a few things then:
Survival or freebuild?
Vanilla or Bukkit?
Who's going to host it?
Whitelist?
Omnimaga-only?

Whoa, a lot of questions!!
I am good with bukkit mods etc, but I can't host it...

TI Z80 / The Happy Parser

« on: June 15, 2011, 10:31:31 am »

This is my happy thread

CURRENTLY REWRITING THE WHOLE THING.
Because it became a mess, and I got some new ideas to make it better. (Learn While Doing lol)

I am working on a programming language for the 83 etc, (But it is easily retargetable, so anyone who knows er, ti-nspire asm for example, could edit some strings and is ready!!)

I made it with JavaScript ~~(I have a strange relation with that language)~~

working on a C++ version, so there is an exe for the winows guys coming!!

Current Features:
-Nice name (Happy)
-Operator Precedence
-Somewhat optimized expressions (Crenshaw hates me now)
-Really platform-independent because it's made with JS
-Nothing more yet...

To show what it is currently able to do:

TI Z80 / Operator precedence...

« on: June 14, 2011, 02:16:14 am »

As some of you know I'm working on a programming language for the TI83/84 etc, but I've got a question:

Do you guys want operator precedence?

It would be less optimized (pushes and pops), but since the compiler is not on-calc, I can work on this. It would also mean more work for me (but that's not really bad)

Computer Projects and Ideas / [JS] A small 4-bit interpreter/emulator

I was bored, and I have a obsession with... Nevermind, here it is.

Made with my iPod Touch (no copy-paste used, everything is ~~hand-coded~~thumb-coded)
Why js?
~~Because I hate Apple Waaah.~~ Er, no, because I can't program in any other language with it thanks to Apple. (ok, it's jailbroken, but php is just ... not right for this and bash... There are still windows users here...

Why 4-bit?

ASM / Assembler

« on: April 19, 2011, 10:47:17 am »

OK, I want to learn z80 assembly, but TASM isn't compatible with my ~~shiny~~ amd64 laptop.

And it is OLD.

Are there better assemblers out there?

PS: I've used some NASM for Linux, so that one would be great

Axe / getKey question

« on: March 17, 2011, 10:11:51 am »

I'm trying to make a key remapping function for DionJump, in Settings, users can edit the keys and the number is saved to an appvar.

But when I try to check the keys, it doesn't work...

Code: [Select]

:If getKey({K+2}) // K is the pointer to the appvar.
: ...
:End

Here is my source, the getKey is changed back to getKey(41), to make the game work. Please don't ask questions about the rest of the code, it isn't really good code, I know that...
WHOA, that's BIG, BIIIIIIIIIIIIIIIIIIIG, did I make that in 4 days

Introduce Yourself! / Hello everybody

« on: March 11, 2011, 04:12:27 pm »

A little introduction.
I started programming in Axe about three months ago, and haven't written a single line of TI-BASIC since then. I am also able to program in some computer languages: Java, PHP, (a little bit) C, (X)HTML and JS, but those two aren't really computer languages. I live in the Netherlands, so if I make any language mistakes, correct me.
I have written a Doodle Jump clone called DionJump in Axe. Currently I'm adding functions to it. I'm also making a clone of Angry Birds, but that one isn't doing anything useful yet.

I hope I'm going to learn much here.
