NXT Games

[muntoo]

This is a topic dedicated to NXT games.

Did you know that you could not only make robots out of the NXT, but games as well? Yes! It's quite possible!
One website that got me interested in making games was: NXTGAMES SITE

Games Wanted
If anyone can post their games/links to their games, I'd be most grateful. It'd be a lot easier, though, if you became a contributor at box.net/mindboards.

Descriptions
Here is a breif description of each game and the person who created it:
(To be integrated into the Box.net repository.)

PSP-Game-Shooter (muntoo) (library files from Deepak Patil, with a slight modification by muntoo):
This game is written in NXC. It is, as of Version 2, a 1 player game, but if someone could edit it, it would great. This game lets you control a "aiming device" with the left joystick on your PS2 controller. And also, you need to press the "X" button to shoot. You have a target that moves slowly, or quickly, somewhere on the screen, depending on the difficulty level you set. Now, enough reading, just play the game! It also has a guide to help you along...


Helicopter (muntoo) (Latest Version is 2.3):
It is possible that the versions after 1.0 require the Enhanced NBC/NXC firmware. That is avalible here: HERE
The first version of this game is a basically a translation from NXT-G to NXC. I got the original program from Frenchie16 on NXTLOG - helicopter 2.0 (video game). My game has more features, accuracy, speed, etc. It is also written in NXC, so it has a much smaller compiled program file size, in proportion to a program written in NXT-G. Now stop reading, and download the program attached! There's also a guide avalible to help you along...

EDIT: Newer versions have been released, way better than the original. Here are some screenshots:





Here is a video of Helicopter Game Version 2.3:




Snow (muntoo):
Winter has come early this summer (as of June 20, 2009). Enjoy a nice relaxing NXT Display Screen as you... I DON'T KNOW! All it is is falling snow particles, and you can edit the settings (Number Of Particles, Particle Radius, Fall Speed, Filled/Non-Filled Snow, Etc). Not a game.


--NXTMemoryGame (NXTboy):
Be sure to download the POST-COMPILED version, if you're just a newbie programmer.
Wow! This game's better than those first two ones I made (or atleast, more complex in programming).
You will need the Enhanced NBC/NXC firmware to run the program because of the "Scaling" feature, I believe. That is avalible here: HERE
I think that NXTboy explains the game better (plus, I'm lazy). Thr instructions are in the .nxc file.


--Connect 4 (NXTboy)
No Description.


--Aliens Game (nxtboy III)

Get ready to fight some aliens...


--AdvGame2 (Sidneys1, modification by nxtboy III)
No Description.


--Star Wars Revenge Of The Droids (nxtboy III)


Your droid has gone mad! Fire lasers at everything else!
Description coming soon...


--Wall Dodger (KeizoomNXTwiz)
"It is a game where you are a circle, and try to dodge as many walls possible.
Though it was written in NXT-G, so it has the awkwardest problems."


--tic_tac_toe (DiEAl)
A Tic-Tac-Toe game for the NXT written in RobotC.


--MicroMario (Arno van der Vegt)
Another Mario Game! But this might be the best one yet... (Sorry Sidneys1, 2Tie)

I could contribute an unfinished chess program - anyone interested?

I'm working on a Pac-Man clone, I guess you could call it. Although I won't give away too much, the final version is going to be full of great features, like easter eggs and extras. (NOTE: it's not a real Pac-Man game, because that would probably be illegal or something. This game is based off of Pac-Man, but with enough differences I'm not breaking any copyright laws )

Currently, I'm working on the grayscale graphics (yes, I said grayscale). I've almost got those done, then I'll make them all as ".ric"s.

I have heard about ".ric"s being much more than just images (something about them having data inputs and changing/moving???). If so, I might look into that and try to use that for the 'Pac-Man', as well as the 'Ghosts' and such.

Once I finish the rics, I'll probably work on sounds, then actual gameplay algorithms, which will be way too hard because I'm doing it in NXT-G. Of course, if I can get it to work properly, then it will be super-awesome. (Esp. since things like this are usually done in NXC .)

Anyways, once I get a bit farther, I will definitely post more (maybe it's own thread).
