Ruin Raider: open source 2D maze game made with kivy

[Raihan Kibria]

Hello everyone,
I've been working on a simple arcade-style game with topdown tile-based graphics for a while now and finally finished it. For those interested the source code and all assets are available under MIT-license from https://github.com/rkibria/ruinraider

Screenshot on my phone:

I have posted the Android package to the Play Store just a moment ago.

That's really cool~ :)

play link for those interested:

(personally I think it'd be more fun if either you had farrrr less health or it was pacman like in that you died the moment a ghost touched you; just because it's pretty easy at the moment, just personal oppinion~ :).

Still, nice to see people making things with kivy~

Doug.

Hi

This is a nice little game, tested it some time ago, performances
however, are not great, and seems to deteriorate as time goes, it would
be nice to fix this, i played on a nexus7 2013, which is google flagship
product, and the game experience was sub-par, the game deserves better
;).

Kudos for the effort, and i hope this can be fixed :)

Hey, thanks for trying the game and your nice comments! Was it the current version you tried? (1.1.1) In the first versions i had not added some optimized libraries apparently and it ran terribly slowly. The current version includes some natively compiled code and should run much faster. For some reason the kivy launcher still somehow runs even smoother than my own compiled package, no idea why.

I finally understand a bit more about how the graphics in kivy actually work and reworked the rendering code in this game a good bit, it should now work far better than it did earlier. It's still not ideal but leagues better than the first version. If someone tried this earlier and found it unplayably slow please try again!

Now it is  playable. What principle changes did you make, what were you doing wrong in the first version?
Also, I think it would have been easier if I could direct the character via a small joystick in a screen corner.

[Raihan Kibria]

Earlier I used to clear the canvas completely on every redraw and recreated all the rectangles for my tiles and sprites again, plus I had a very inefficient procedure for rotating sprites. This was in hindsight of course terribly slow. Now I only build the picture once and reuse my rectangles and rotates, and only set their textures, positions and rotation settings on redraw.

I'm not sure if a joystick in the corner would do much for the game though, why is it inconvenient to just touch the screen? Do you think it would feel more like handheld videogames if you had a simulated "thumbstick" on-screen?

Raihan,
I think I would be more efficient in the game if there was a "joystick". I can imagine it being even more difficult on a bigger screen like the way it currently is.
Anyway, congrats for the game. One day I plan making my own, of this type.

I thought about your suggestion a bit and sat down and made a little joystick widget in kivy, and it was quite easy really. A gif of it in action:

I think it works quite well, and it is probably more convenient to use on a tablet or other large screen device. Thanks for the suggestion!

Posted the version with the virtual joystick on the Play Store! Please give it a try!

[Milos Gradjanin]

That's great now, the joystick makes it easier.
