Topic: Petit Computer

Got bored so I combined @Calc84maniac's Raycaster with his Raytracer.

It is SLLOOOWWWWW but is it something you'd like to see implemented in Minecraft DS? As a toggleable option?

Ok can we stop talking about Minecraft get-togethers now? This thread us for →PETIT COMPUTER←, NOT Other things such as Minecraft.

How would I use those?

Got tired of programming Minecraft stuff so I got bored and made an interpreter. A VERY VERY basic language I call SimpleBASIC. The commands:

OUT<Text
Prints text on the screen

INS>String ID
Inputs a string

INV>Variable ID
Inputs a variable

SCLR
Clears the screen

SLO<Text
Prints text on hte screen, but the next command will be on the same line. Same as PRINT "Text";

VCLR
Clears the variables

GCLR
Clears the graphics

BUT[Button ID]
Waits for you to press a certain button

SLP[Seconds]
Waits for an amount of time

SND[Sound]
Plays a sound effect

STILL TO COME:
ADD[Variable,Variable]
SUB[Variable,Variable]
MUL[Variable,Variable]
DIV[Variable,Variable]
POW[Variable (base),Variable (exponent)
WHEN (condition) DO[another command]
DRAW._DOT X,Y,Colour
DRAW.LINE X1,Y1,X2,Y2,Colour
DRAW._BOX X1,Y1,X2,Y2,Colour
DRAW.CRCL X,Y,Radius,Colour

It has a functional interface, and I have already made a few basic programs. Should I continue? Is this a waste of my time? Do you want the QRs? Does this sound really dramatic? Will I ever run out of questions?

@IamAPerson should I really continue Small_Math? It seems like something that many wouldn't need.

Huzzah! Got the level editor set up so now I can add and place entities into the user-made levels (without having to manually add them externally). Also, I have implemented the dreaded appearing/disappearing blocks. Won't those be fun to deal with....hehehe.....

Now to work on more enemy A.I.

@Discostew sounds like you're wrapping things up .

@Bluerobin2

Wrapping thing up is a phrase usually used when completion is getting very close. There are still a number of things that must be dealt with that I have yet to touch, or even conceptualize because I've been busy with what I currently have planned out in my head. I don't expect this to be finished before the end of the year, at least from what I've examined.

How viable would it be to use sprites and CHRSET as a sort of pixel buffer which could dump up to 256 pixels to the screen at a time instead of drawing on the GRP for something like 3D drawing? You know, have some sprites set up in a grid that don't move (all scaled to 200% to effectively cut the resolution to 1/4), have an array which represents the screen (and since there are only 16 colors, you can reduce the number of stores by storing multiple values in a single variable), and dump the values into those sprites using CHRSET (there would be 192 calls for a full screen with sprites scaled to 200%). Would this just be ridiculously slow? I'm certain many people have tried this before, and there's probably a reason why it's not usually done... I just wanted an opinion on it. I thought maybe the speed of sprites would counteract the slowness of all those CHRSETS and assignments. I'd love to try it myself, but I'm ridiculously busy at the moment.

Anyway, sorry for my silly suggestions. I just wanted to know if anyone has tried this before, and what the results were.

Hello there,
I know that this is a petit computer topic, but anyway, here is a very early version of what once was "Prisiorrento!" for 3DS:

@Bluerobin2 I was mainly making SimpleBASIC for myself; I was just wondering if anyone else wanted it. If you don't want to work on SM, then I'll take the QRs. For me, I think it's cool and you should continue, but don't feel forced to work on it. That's part of the reason I'm taking a break from Minecraft DS. I felt it was like a "job" and I had to do it.

I have a question. For my interpreter, I have a command like this:

WHEN (Data type)[(ID)] (comparing operator) (ID) DO{
Commands here
}

It's sort of an IF...THEN statement but it's WHEN...DO. It's similar to the C++ format.

if(stuff){
do stuff
}

An example would be:

WHEN VAR[0] = 1 DO{
OUT<Cool!
}

That means that if the variable in slot 0 equals the variable in slot 1 then print "Cool!" My question is how would I pull this off? I know of a way but it'd be very slow. If you use STR[] then it compares 2 strings.
EDIT: Nevermind. I got it working. Here's what I just used:

INS>0
INS>1
WHEN STR[0] = 1 DO{
SND[1]
OUT<Yes! They're the same!
}
SLP[2]
BUT[16]

@IAmAPerson I made a text editor which could be useful for people who are trying to make interpreters, you can check it out in the QR sharing thread, it should be the first post on page 79.

Hello,
Im going to make a new game in petit computer.
But i dont know wich Genre i could choose. I like simulation games like Animal crossing, but i think im
not able to program that.
Can someone give me a suggestion?
Thanks

2 new commands: SETV and MATH.
SETV sets a value to a variable/string.

SETV STR[0];Phil

Sets the string "Phil" in string slot 0.
Math executes a math command.

MATH 0;+;1;2

Adds the variables in slots 0 and 1 and stores the answer in slot 2.

Pfft, well my idea is totally useless. I get about 5 frames per second WITHOUT any 3D processing AND only a quarter of the resolution (I'm just setting pixels based on the global timer). Well... oh well. I guess CHRSET is just too expensive.

I didn't quite get what you were suggesting in your previous post. Were you talking about plotting pixels by forming strings from them to be used for CHRSET, which then reflect what you see on the screen because the sprites use them?

This is kinda off topic but, is it wrong that since I play Minecraft so much my fingers are always on keys A,W,S,and D

@programmerpro you double posted. @Hansausage awesome job on the MCraft DS launcher! @levicljr good job on your MCraft RPG!
