So...
This is is something I made mainly to get better at using some of the C commands, but it sort of turned into a game. Laughing You may have seen it in my C/C++ Questions topic (Thanks again for all the help guys).

Its not much now, but what it is is a simple shooter where zombies are approaching from all around you and you must fend them off. Its very simple, you can only turn around in a circle. I turning and firing done so far, and if you can think up a better name, please tell me. Razz Right now, all I have is a target, but I'm currently working on the zombie sprite.

Here's a screenshot:
So it's an FPS game? Sounds like it could be interesting. Stuff like this makes me wish I had a CE...
Wow, really good hand and gun graphics. It looks really cool. Very Happy
Looks like the wolfenstein hand, pretty sweet and seems like it moves at a decent speed so far!
Nice job so far! I too like the animation Smile (I also wouldn't mind taking a look at the code Razz ) Keep up the good work!

Has anyone thought of a better name yet?

Currently, I've just been making it faster and working on the sprites. Not much has changed about the program though.
I think Zombies is fine Smile
looks pretty good! Very Happy I also think zombies is a good name. I like how the gun sprite looks for it kind of reminds me of the old Doom games. Anyways, I think this game could be awesome and keep up the good work! Good Idea
So a CE 2d fps... fascinating! I'm really looking forward to see what this evolves into.
/me starts coding

Ok, I'll keep the name. Smile

Recently, I added the (test) enemy sprite, and now something causes it to not compile right. It doesn't display any errors, but the screen gets super weird and the emulator resets. I'm pretty sure its not something with the new sprite. Can anyone see something that could cause this? Also, please suggest any optimizations you see.

So, as it turns out, my problem was that my sprites were too big. Razz I made them a (lot) smaller, deleted a bunch of empty space that I should of gotten rid of in the first place.

I also was having trouble on my own zombie sprite, so I'm just going to use a monster from Doom. I don't have any screenshots yet, I'm still rewriting a lot of code, but I'll have some soon.

EDIT: I added in all the sprites. I still need to edit the new Doom sprite, but other than that, I'm done with sprites for now.
Looks great! Do you think you could add a black hole where we shot the zombie? Just to be sure we actually killed it. Smile
Thanks! Yeah, I made a sprite for that. Smile I just haven't implemented it yet.
Looking pretty spiffy for sure! Keep up the good work Smile
Cool cool, very in your face with the size of the sprite ... sure to produce a few scares Smile.
If I'm right, you use 2 buffers and 'switch' between them using gfx_Blit or so, but it might be a lot faster if you replace that with gfx_SwapDraw or something like that Wink
I added some more functions, and something went wrong (as always). Sad I'm hoping more sets of eyes will help. It compiles, but it freezes when I run it. Here's the code.

Recently, I've been cleaning my code up. This means I'm using local variables and wow - multiple files (Never done that before Laughing. It feels really wierd not using global variables for everything.). I've also added all my code to github so that users can review it. Hopefully people can correct my code Razz.

https://github.com/Calcnerd/Zombies-TI-84-CE-

I also still have a bug where the calculator resets if I try to turn. Sad
Eeep
Sorry, Calcnerd Razz
I forgot i was supposed to me making stuff for you... i started, but havent finished
That reminds me... I owe people like 300 different programs...

Aww screw it..

That code is very pretty, very neat, very long, very awesome, and very confusing... (I should really learn C)

Seems like very good code, if you ask me.
Guess who rendered a 3D cube in 5 min in BASIC on his CE last night... shhh It's a secret...Amazing job!
