PSP Game: Simon

[PorpoiseOfEmail]

Hello All. I've decided to take a shot at deving games on the PSP. Ive been coding for god knows how many years now. Most of my C/C++ knowledge is in data structures/data abstraction sadly. My game work is in java. So bear with me while i struggle with some of the graphical/animation stuff. Anyways, i decided at first ill create something really simple to help familiarize myself with the psp environment. So i decided as an exercise in button recognition, I'd create the game Simon. You know, a random pattern of buttons appears and lengthens by one each time and you gotta follow up by inputting the stuff in the correct order. A memory game.

Revisions to v.08
-partially working options menu
-high scores list
-difficulty setting (1 to 5...1 being hardest)
-source added

Revisions to v.09
-All new graphics and animation
-timer option for input
-sound?

I'd recommend searching these forums here:

Sounds like a real cool game that will stress users with no end =)

Even though you're a more advanced coder ( :dance: ) I think these tutorials will help.

Click here

The first one will probobly help you more. It's a VERY well writted tutorial on how to get your psp dev compiling enviroment set up.

The second might also help, just a guide on how to program a simple Hello World program.

-cheers :dance:

Thanks. I already read through those ^_^. Not exactly what i'm looking for though. My program works already, but the commands that flash on the screen need to be stalled long enough for the user to read them. Maybe one of the later tutorials will help ;p
Thanks anyways though

Is it all in a single thread, or is your program spanned over multiple threads?

single. i suppose multithreading would be a way to do it. I was hoping i could avoid it if possible

[Yeldarb]

With a single thread it's easy to pause it

Use something like this:

void pause(int seconds) {
	time_t startTime = sceKernelLibcTime(NULL);
	time_t curTime;
	time_t difTime;
	time_t counter=0;
	
	unsigned long ctrl;

	while(counter < seconds) {
		curTime = sceKernelLibcTime(NULL);
		counter = curTime - startTime;
	}
	return 0;
}

And then call it like

pause(5);

To pause for 5 seconds.

Hmmm...makes sense! I'll give that a try. I'm such an idiot sometimes. OFCOURSE I CAN USE THE SYSTEM CLOCK. geez

thnx

Any time. Just a disclaimer, I wrote that off of the top of my head and didn't test it, so it may not work :P

I get the idea though. It is never a wise idea just to straight rip code anyways. Thanks a bunch.

Hmmm..i had an idea. After getting what i want working, WORKING, such a type of game could be changed up to be a music/rhythm game with some work. Maybe ill open-source this after awhile and see if anyone wants to make a DDR/parappa rip off for the psp

[PorpoiseOfEmail]

prototype is up!

[PorpoiseOfEmail]

First real playable version is up (aka: u can lose)

This is fun and has some real potential for growth =D Sounds would be very cool, like that one simon says handheld saucer thing. Maybe try to confuse the user with sounds and images lol. Regardless, it's very cool to see memory games come out, theyre always fun =)

^_^. Well ive almost got all text replaced with images. I'll post an updated version when that's working. More images and sound would be nice though, and yeah, the hand held simon was inspiration. However, once i get the basics done, i hope to evolve this into a ddr/parappa style game.

ULING image version now. v.06 almost up.

DDR might be too fast for PSP controls, especially with the issue on the square button. but either way both of those are very music critical. anyways, i'm still following this development. (you made me register lol)

hahaha. Well, i was thinking more parappa the rapper than DDR, but we'll see what happens.


Next iteration i should have pictures centered and a scoring system going.

Cool! Simon is one of my favourite games.. or well.. the more high-level implementations of it, like Space Channel 5

Are you using SDL to do this?

I'm going to likely have to recode most of this at a certain point. As I said earlier in the thread while ive done game programming etc, its been in java. I know there's probably more efficient ways to get these images and stuff up and animating other than using a jpeg converter and using pgBitBlt() to display them. Alas, i dont know much about programming graphics/sound for c/c++ and even less about psp stuff. So eventually my updates will slow until i learn more. Ofcourse if anyone wants to point me in the right direction, I'd be more than willing to listen ^^

v.07 up

[thedan]

I'm really liking it alot =) for some reason this reminded me of a game called Bop-it that you can buy in wal-mart or wherever. The one with music and a voice telling you which one to press/pull/flick etc.. it was a real fun game especially with some alcohol =b

Anyways, you're making some awesome progress in no time and I can't wait to see how this ends up more polished =D

use kxploit to load it

Anyways here's an update:
basic high scores are working

Ill need another day or two before i release v.08 though. Im kind of busy with some things, and I want the high scores to be saved even after the game is terminated so it doesnt give a new list each time ^_^

Anyways ive decided for the following two updates to work on the graphics even further. It'll be a complete overhaul and end up much nicer looking in the end ^_^. I'm also almost positive within the next 3 updates ill add sound too

wooooo! confusing sound?? =D i love thinking games, they have a real world use as well as fun.

My plans for sound will allow this to eventually become a music/rhythm game ^_^, but for now, itll add some atmosphere and maybe confuse ;p

Ah, music!! That will surely make the game much harder, by the way: keep up the excellent work :clap:

[OmahaStylee]

Awesome program! Good job so far! It would be great if you realeased the source code!

[PorpoiseOfEmail]

Source code might be cleaned up and released sometime soon. Anyways, ive almost got the highscore list working how i want it to...meaning it reads and writes from/to file. ^_^

Awesome!

[PorpoiseOfEmail]

OK folks, Simon v.08 has been released with source as well. See first post for revision info and files. Sorry it took so long. I spent too much wasted time with sound to no avail. If anyone wants to help out with getting sound working, it'd be much appreciated. If not, im sure ill get it, but not sure when ;p

We are patient, downloading it now I love memory games, now let's see how good I'll be at the old arch enemy..Simon

One suggestion, make it noticable when changing signs. I had two X's right after each other and it was non-noticable that it changed

That is will not be an issue next version, but the next upgrade might take some time so i might make a quick fix instead ;p
