Fast-RPL version 0.6

kuda · Post by **kuda** » Sat 19 Mar, 2005 11:17 pm

New version of fast RPL is Out, it include :
- a better editor (few improvement)
- Matrix
- Rand, Input , line, rect
- librairies support
- Mapping scrolling pixel by pixel routine ( really fast)

3 samples availables:
TUNNEL10 (a classical)
MARIODMO (a DEMO a mario like game, need Pic9)
CITYDEF0 (defend a city by detroying bombs before they fall, nice, smooth and fast... -> need Pic9)

Tutorials have been upgraded

Everything may be found on
http://tift.paxl.org
or on
http://kuda.dyndns.org/leo/fast_rpl/
(my server might be unavailable for a few day)

On CALC, all this games looks lot more smooth (Tisshots fault.... )

Damm, nice demos!!

That mapper, is it dwedits?

The speed looks Nice.

Look very nice so far! I saw it on the french forum. As you said before programs are going to be compressed so huge games will be possible to make with this and it run pretty fast.

However I think that the language look complicated to learn. The syntax is easy, but to understand how some instructions works it's another matter. I mean it would be cool if this programming language could be used by those who don't know any ASM at all

FastRPL instruction doc wrote:Token
In (stack before)
Out (stack after)
Out-In = Diff
Details

0-65535
.../
... / N /
1-0 = +1
Push a number

A-Z a-z
.../
... / value of A-Z /
1-0 = +1
Push a var

+
... / X1 / X2
... / X2+X1 /
1-2 = -1
Add 2 elements of the stack

-
... / X1 / X2
... /X2-X1 /
1-2 = -1
Sub 2 elements of the stack

ÃƒÆ’Ã‚Â¼
... /X1 /
... /
0-1 = -1
Pop to a var (for example, Ax+B-ÃƒÆ’Ã‚Â¼y will do B-(A+x)ÃƒÆ’Ã‚Â¼y )

A BASIC programmer who doesn't know what is a stack, a push, a pop and stuff like this will get a headache trying to understand what those instructions do. Ok I know this sound a bit like the Asmguru logic but you should try to explain the language instruction more in a TI-BASIC way than an ASM way so non-ASM programmers doesn't have to read Asm in 28 days to learn fast RPL. Just a thought like this because this language look interesting and I might try to use it if I have time, it's just difficult to understand (for those who have difficutly understanding ASM like me).

yeah thats kinda the reason I didn't fully like it, The stack is something hard to learn and deal with when your learning asm. But the potential this shows may make it worth the learning effort.

The text you just mentionned is for people that want to use the maximum of my language... I made another tutorial that is much more understandible for basic programmer I think...

http://paxl.org:2080/~tift/archives/Fas ... %20ENG.htm

About the stack, I konw it's not always an easy thing to understand, but I choose to make a RPN based language, so what is RPN without stack...
Moreover, the concept of the stack is explain in my tutorial... But maybe my explanation are not good enough, it's jhard for me to try to forget all I know about this language to make good tutorials...

So kevin, did you read this tutorial ?? Is it to hard to understand for non ASM prgrammers ??
Thank you for your help

I couldn't get that file to render the special characters in IE and even with the font. I could in other browsers, not IE.

kuda · Post by **kuda** » Sun 20 Mar, 2005 8:52 am

Hum, I had the same trouble, I fixed it by :
-removing the font from font directory
-trying to read the file
-reinstalling the font in font diorectory
-trying to read the file again
-rebooting
-> then it worked... This font is a big trouble, maybe I should remove it from the tutorials, but how to deal with Ti special token ??

About compression, I think their was a misunderstanding... RPL script are not compressed, but matrix take a lot less space than in basic...
In basic each cell nee 9 bytes as it is floating point numbers, but in Fast_RPl you can make 1/2 bytes, 1 bytes, or 2 bytes cell... For the mapping scrolling routine you must use 1 byte (8 bits in the importing matrix menu).
So, if you use matrix, yes, your game may shrink a lot, but not by compression.
Also, I think that if you become a good RPL programmers, the same code will be smaller on RPL that on BASIC, and a LOT FASTER of course....

You really should try it, dont hesitate to ask me by mail anything you don't understand or you don't know how to code...

It's the same tutorial I've read. Knowing that you speak french are the french tutorials going to be ready soon? Also if I make a game with FastRPL 0.6 am I going to be able to edit it with future versions as well?

Nice! looks like this can certainly compete with MLC (on the 83 anyways).

DJ_O · Post by **DJ_O** » Sun 20 Mar, 2005 5:55 pm

It would be cool if the 83+ would finally have programming language other than BASIC and ASM. I mean the 68k has C, ETP BASIC and GFA BASIC, which the 83+ doesn't have

kuda · Post by **kuda** » Sun 20 Mar, 2005 6:27 pm

Hum, make tutorials in french, well I could... when I have the time...
The script you make with version 0.6 will of course be compatible with futur versions, as nothing is removed, only new stuff or improvment...

I let myself do some changes from 0.4 to 0.6 as the division (now the rest is not given, but there is a modulo function), because nobody exepted me has released RPL script...

Compete with MLC ? well in fact this is not my goal. It's true that both project could have been grouped (in fact I would have join their project, power of the number... I was alone, they are a hjole team) but I realised that this two languages don't aim same goal, and same programmers...
Multi platform is a great Idea, but that's nt what I like to do... I like optimisation and RPL is the fastest language to interprete, but it's a bit hard to get use to the syntax...

I hope some of you will release small or big games with fast RPL...
The next version 0.8 , will have a totally new editor, the interpretor and editor will be apps, and McBeach and I will release the project for a large public) not only on spcialised forum... So that would be good if we already have a large number of samples...

Thank you

Big game sin RPL would be cool. I hope that RL3 or FFTOM games will be doable in it (they take between 120 KB and 400 KB of archive memory on a SE

) but even if it's not I'm sure it will still be suitable for RPG or such games

The editor as an app will be a good idea as it will not use as much ram so most of the RAM could be used for the game itself

Wow, i knew RPL would come along nicely

.

MLC has some serious competiton

Could you make ION support?? That would be really nice.
