Title: Skyway 89 Beta 1
Post by: arti on December 31, 2005, 05:21:00 pm

After experimenting with 68k BASIC as well as with TIGCC for more than a year, this holiday I decided to start working on a serious game. It is a sky-shooter game called Skyway. Skyway will eventually be on many platforms, but I started with the TI-89 because development time was faster and funner.

Please visit the link above and give me feedback. The game is far from done, but I wanted to release an early version on New Year's Day as a small gift to the TI community :)

Happy New Year!

Looks Sweet. I'll have to try it out tommorrow. You'll have the pleasure of knowing that your game is going to be the first game I've played on my 89. You should feel special.

Wow this looks awesome! If only I could make greyscale graphics in 68k C :(

Post by: tenniskid493 on January 01, 2006, 12:36:00 pm

WOW!!! I just tried it and it is amazing. The Graphics are sweet and I didn't find any glitches. The one thing is possibly an option when you die to restart, not have to close out and start again. I think the life bonuses and weapon upgrades would be really sweet too and help a lot.

Post by: arti on January 02, 2006, 06:44:00 am

Thank you for your kind words. I agree, bonus powerups will really enhance the game. I also have a nice idea for a bonus that will set Skyway apart from other shooters, you'll see ;)

The file just got approved on ticalc.org, http://www.ticalc.org/archives/files/fileinfo/382/38294.html

Keep the comments comming!

PTI only run the 82/83/83+ O.o did u meant VTI? Which ROM were u using? I was using 2.03 and I sent the only calc file included in the zip file to it (skyway.89z) and did skyway() and this is what I got I have that problem with lot of other games as well :(

thats why half of the TI-92/92+ RPGs in the archives arent reviewed :(

Post by: BCTurk on January 03, 2006, 02:13:00 pm

Oops, did I say PTI??? Guess I did :oops:

. I meant VTI, and I believe I was using 2.09, but I'm not for sure.

Title: Skyway 89 Beta 1
Post by: DJ Omnimaga on January 03, 2006, 02:17:00 pm

in VTI 2.04 or above had very low contrast and I barely saw anything. I couldnt even change the contrast

Title: Skyway 89 Beta 1
Post by: BCTurk on January 03, 2006, 02:20:00 pm

2.09 OS off the 89 I mean, I was using 2.5 (is that the newest VTI??, if not, whatever is the newest version is the one I'm using)

Title: Skyway 89 Beta 1
Post by: DJ Omnimaga on January 03, 2006, 02:25:00 pm

2.5 is the new one. there is 3.0 alpha but it only run the 83+ and wont even send programs

Title: Skyway 89 Beta 1
Post by: arti on January 03, 2006, 03:13:00 pm

I use http://www.ticalc.org/archives/files/fileinfo/84/8442.html with http://education.ti.com/educationportal/sites/US/productDetail/us_os_89.html - just send skyway.89z, that's the only file you need :)

This way I get to see how both regular 89 and 89T handle it ;)

Hey, this is really sweet! I love shooting games, and this one looks really nice. :D

Downloading to my 89t now. It would be really nice if pti could load 68k roms 'cause it pwns vti, but oh well.

If I remember correctly AMS 2.00 through 2.04 had an executable size limited to 8Kb.

AMS 2.05 to 2.09 are limited to 24Kb.
AMS 1.xx and 3.xx are limited to the full 64Kb.

If your executable is greater than these limits, you need to use TTstart or Superstart to launch your program.

Hrm, seems to work fine on my ams 3.10 89t. For vti, I have a rom of a regular 89 with ams 1.00 on it. :D

Works fine there too.

Oh hey, you know what it needs? A cool exploding spaceship animation for when you die before it puts up the losing screen. :D

If you wanna get really fancy, make some exloding shrapnel that hits and kills other enemies on the screen.

Title: Skyway 89 Beta 1
Post by: arti on January 04, 2006, 03:21:00 am

Spengo, I'll definitely do that! Also. future versions will have a menu rather than a screen and the exit.

Kevin, here's a http://artraid.com/alex/wp-content/uploads/2006/01/skyway-ppg-beta1.zip! Send both skyway.89z and skyway.89y to VTI, and run skyway() as usually.

OMG HOLY F***** SH**!!!! This gotta be one of the best shoot em up game I ever played on a calc, this was kinda wacky seeing all enemies going in different directions :D

awesome work arti I hope to see this featured :)

Post by: saubue on January 04, 2006, 05:11:00 am

Why are you all still using VTI? Use TiEmu!!

Besides, the game looks really cool, the only thing I'd like to mention is that is a little fast - different possible speeds would be a good addition.

Title: Skyway 89 Beta 1
Post by: DJ Omnimaga on January 04, 2006, 06:45:00 am

well VTI grayscale is sometimes better than in TI emu, it really depends of the game

Title: Skyway 89 Beta 1
Post by: spengo on January 04, 2006, 10:45:00 am

Nah, I don't think it's too fast. But then, I always play pheonix on the fastest available speed so...

The levels seemed kinda short though. I beat the entire thing in a very short time. :o I think that entire beta release should be like level one of the finished game.

Title: Skyway 89 Beta 1
Post by: arti on January 04, 2006, 12:34:00 pm

There's a reason why it's a beta ;)

The beta's composed of 4 individual levels 'fast-forward'. For now, each short level lasts 1000 frames regardless if you kill a number of enemy ships or not. As for the game being too fast, don't worry, it will be hard to keep it to its current speed. There's a reason why the status bar isn't displayed during gameplay (major slow-down :(

)

Regardless of how the game will turn out, one thing I can say is: it will be a long, long one :ph43r:

any chance of a port to 83+ series in the distant future?

Post by: arti on January 06, 2006, 02:12:00 am

If http://www.ticalc.org/archives/files/fileinfo/380/38061.html grows and gets a decent library (at least sprite functions), then I will give it a shot. Of course, probably without the scrolling background and grayscale.

Now that would be a fun project! Getting the TISDCC a good graphical library.

Hmmm... I actually have a Z80 Assembly instruction manual. I have never really looked at it before.

Post by: Liazon on January 06, 2006, 12:48:00 pm

Perhaps he should ask if Joe W. if he could use the ION libraries for sprite stuff.

Ti-83+ ASM isn't that bad. It just takes a lot of getting used to.

Post by: DJ Omnimaga on January 12, 2006, 03:50:00 pm

How is the game progressing so far?

Title: Skyway 89 Beta 1
Post by: arti on January 12, 2006, 04:29:00 pm

No progress I'm afraid, except for some ideas to be implemented later. School is keeping me very busy at the moment. Perhaps the next release will be around the Easter holidays.

Title: Skyway 89 Beta 1
Post by: arti on February 13, 2006, 02:52:00 pm

In a moment of curiosity I grabbed my 89T with beta 1 of Sw and a stopwatch, and calculated Skyway Beta 1 to run at roughly 70 FPS (each level is 1000 frames, and it spans 14-15s) :)

I also got an idea on how to include the status bar during gameplay without lowering the frame count too significantly.

Also, after taking a long break from programming Skyway (a break that's about to get longer btw, thanks life :)

), the source looks more legible and easier to understand (go figure, since I am the one who coded it in the first place :-\) All in all it's gonna be great when time will grace me with some of its rare spare moments.

w00t nice to see its still alive, and 70 FPS its fast O_O

VTI must suck because it seemed to run at like 8 fps with me :(

I'll try in TI emu I think. Keep up the good work on this

I need to add the beta in my archives someday tho :P

Post by: kalan_vod on February 14, 2006, 06:48:00 am

Very impressive, I think that is super fast! The only game I can think of (on the z80s) is pheonix with like 3-40 fps.
