i suggest you to learn asm instead. C is slower, bigger and you have
no REAL control over what it does with your calc.

I also experienced that it is more difficult to learn c than ASM!

I think bitwise is getting me some tutorials on this subject, I may very well use ASM, but for now I'm stuck with C.

by the way, I have two questions:

1) in Casio2.h some functions require a state parameter, I cant figure out what this is, mabey beacuse most of the comments are in french.

2) Can greyscale be done using C, or does it require asm?

[huhn_m]

the state parameter is 1 or 0 (to set the pixel to on or of)
Grayscale can be done with both languages I think!
(Super-Bomberman is written in C I think)

[rjstephens]

wait a second. weren't you doing this in BASIC?

[huhn_m]

Hey! rjstephens

keep realistic! As BiTwhise said it is NOT possible to write an interpreter
in an interpreted language!

It would:

*Be VERY SLOOOOOOWWWWWWW
*Use 40 Bytes for 1 command with 4 parameters
*Be very big (> 15K I think)
*Not support strings either (if it would it grows even bigger and slower ...)
And you wouldn't be able to use it on an CFX at all:

30KB - 15 KB = 15KB ram left.
15360 / 40 = 384

This means you would be able to execute the HUGE amount of 384 commands
on a CFX!

[rjstephens]

oh well

better get an afx. too bad they are so EXPENSIVE

384 commands - that's not too pad.

[huhn_m]

I didn't mean a set of 384 commands but
the largest program you're able to develop
can contain 384 commands!

Can greyscale be done using C, or does it require asm?

You can do (almost) anything with C.
It's just, sometimes certain operations are easier to code in asm. These parts can anyway be done with inline assembly.

The biggest difference lies in efficiency, both in size and speed of execution.
A C program can never beat a well written asm program (with todays compiler technology, on this machine..)

Yeah? Casio Basic it?s really slow, it?s very bad for great games, for that you must know C or assembly, for me it?s easy to learn C, the assembly it?s very difficult

[Brazzucko]

Of course for some little mat programs the CASIO BASIC it?s enough

[CrimsonCasio]

rj, I am planning to compleat the BASIC version first then I will try to make it in C... the big thing is that I will continue to read the matrix from a basic file therefore making it possible to create on calc games, it should be faster since I will leave out most of the math functions.

also, thanks for the help, I will probably need more...

[Brazzucko]

Excuse me to post this here, but is for not create a new topic?..

Some one can send to me a pic of the system.exe from the FX Plus or AFX Plus, ( using the FA-122 or FA-123 software for that )?

It?s for friends that are creating a new and very cool system fake??.

Tanks.....

Now about games there is any program that can read at full speed Basic programs, as everyone knows the original Casio program are not the best program to do that??.

[BiTwhise]

Noone has made a new interperator to read Casio Basic files, for some simple reasons:

We don't know how to access the math API of the calc, so this would have to be written ground up
For all we know, this math interperator might be integrated with the basic interperator (since you can type basic code and execute it at the commandline..)
If this is the case, we would have to write it ground up anyway to improve it


I was thinking of writing a new basic-like language for the calc..
Don't have time right now, but we'll see what the summer brings
(first I need to write a floating point library, a math API, and then complete my 3d grapher )

[Brazzucko]

I will wait for that.......

i've only the cfx9850gb+, so no c or asm for me . But I like the challenge of making fast games in casio basic. It is possible, just code smart

[CrimsonCasio]

Exactly! thats the reason I've stuck with BASIC for 5 years, and even now that I can do C I will probably continue with basic as well.
