Title: Anybody here have a Mindstorm NXT?
Post by: nxtboy III on February 15, 2012, 07:09:00 pm
Hi,
I was wondering if anybody on this forum has an NXT. If so, then please reply and say so, and also because I wanted some help and ideas for my NXT game (called After Dark, in my sig) posted here on Omnimaga.

Thanks, and have a nice day,
nxtboy III

Do you know if there are any model (that could support your game) under $150 or something? The main issue is that most people here are under 18 and barely have money (or already used it or their parent money on a $150 TI calculator and consoles) so since the Mindstorm NXT I saw was like $300 I doubt many people here bought one or can afford one. :(

Well, you don't have to buy the whole set to play this game. You could just buy the brick separately from the company (About $150) or buy one off ebay (I got one for $90, (Buy it now, not bidding)). But you also need a touch sensor ($19 from the company). You also need a connector cable (Same as a printer cable, cost about $5 or less at walmart). All total, if you bought an NXT brick for $90 off ebay, it would cost around $114. The software that I use is free, and better than the software (Made by the company) that costs money.

EDIT: Here's one for $99.99

I've got one of those.
I made all the constructions that are on the CD, but I never succeeded to make one without it...

EDIT : Also, I've never tried to program it in NXC... That sounds fun, I'll give it a try.

Ok. Check out my game, After Dark, in my signature. Ask if you want the program.
Oh, and the game is in grayscale!

Ah that's good then. I might check that stuff out, providing it ships outside USA too.

I have one (somewhere...), version 1.0 I believe, but I haven't done much with it, mostly stuff just like what Chockosta's done.

Cool! Could you maybe give me some ideas for my game, in my signature? Just post it there.

My mom wants to buy one ^_^

Cool. I myself should maybe try to get one at one point. That makes me wonder... do we have to type programs on it by hand or can we send them like a calc? If for example Nxtboy was to finish his game (he should maybe ask multiple forums for levels help since only on two semi-quiet sites it might take forever or maybe switch to tilemapping) I would like to try it, but not if I have to copy about 20000 bytes of code by hand O.O

The programs are written in C or in a graphical programming language, then compiled and sent to the device. Like a calc, yeah.

On the idea level, keep in mind this has similar resolution to the 84+ (Actually closer to the 86, but whatever) and a processor similar to the nspire's.

I recommend putting in fancy-shmanacy physics.

Isn't it slower than the 84, though? Often nxtboy tested programs on it (in ASM) that ended up running slower than their 84+ counterparts. ???

It had better not run that slow. It has a 48mHz arm CPU inside.

Maybe the OS has a lot of overhead.

Unless, he was programming for the coprocessor, which only runs 8 mHz and is an atmega chip. They're RISC cpu's too, so the comparison is skewed a little bit to their detriment.

Yeah that's what I thought. Or maybe the code was horribly unoptimized, although I doubt it, since it's quite hard to make a counter that is unoptimized  this much.

It's not as hard to make unoptimized C as it is unoptimized assembly, especially if it's a customized, proprietary compiler.
