Ard-Type - an R-Type tribute

[annyfm]

Started a prototype just before I go on holiday tomorrow (to put my programmer brain to rest! Though I am taking my laptop, so if I have a particularly boring time maybe I'll work on this more...)

Anyway, I started making a shmup:

An R-Type tribute for Gamebuino. Very work-in-progress at this stage.

How to 'play':

• Arrow buttons U/D/L/R move your ship
• Press A to fire bullets
• Move around and fire bullets at the same time to modify their direction and velocity

You can view/fork the source on GitHub. Or if you just want a ELF/HEX to try out, here's a direct ZIP download link for the binaries.

The direction/velocity modification of bullets isn't strictly a traditional shmup mechanic or particularly innovative - I borrowed it from Geometry Wars, actually - but with a small screen, slow movement speed and potentially lots going on (I see this eventually becoming a 'bullet hell' type deal) I thought it could be pretty neat further down the line...

Not bad

I like the feeling of the bullets' direction/velocity modification, I look forward having something to shoot

pleeease, pictures for those without a gamebuino and too dumb to work the emulator

Certainly, see attached... Yeah, it's just a triangle and some dots I'm not really so hot on the art side of things - but when it's more complete (i.e. not just a controls prototype) I'll start figuring out how to do sprites. I've looked at examples in other projects (Senet for one) but it's beyond me right now!

Also bear in mind this is an arcade game and without an emulator (cause I work on Mac/Linux) I can't take an "action" shot, so you don't see the direction/velocity manipulation of bullets. It feels pretty good to me though. Thanks for giving it a quick spin rodot!

I actually started making a schmup of my own, the other day, but hadn't got round to posting it here yet.

(hex and elf in /dist/Debug/Arduino-Windows)

Here is a video of what I've got so farwhat is there so far:


I have a few Ideas for how to implement different enemy types and preset levels.

The emulator works fine for me in Linux using wine, use a command like

Code: Select all

wine <path to gbsim.exe> <path to your .elf file>


The sound currently doesn't work, but I think it's not implemented in the emulator.

Nice images and videos on the different games, thanks for posting.

Out of curiosity is there a reason why you use floats for positions and velocities for bullets rather than bytes? (Bytes usage is better)

Ignorance

edit: will expand on that a little... I'm not really a C or Arduino programmer, I actually come from a predominantly PHP background (which is how I make my living) and while I understand static tying in principle and casting, working in a dynamically typed language leaves me somewhat at a loss for the pros and cons of certain types (like I know float is more computationally expensive than int, but not a lot more than that!)

edit 2: on that note, any chance you could elucidate the benefits of byte over int/float?
