If you want to try it, just place an unzipped game or a .love file onto the sd card ( /mnt/sdcard/love is the path apk searches for games )

Nice one.

I want to see this go places! I wish you the very best of luck!

Wow. What kind of performance do you get? And how does it deal with different resolution devices?

[ghoulsblade]

performance depens on device, but good enough for small games it seems =)
there's prolly still lots of room left to optimize, but that's not a priority right now, still a lot of the api is missing.

resolution : by default it rescales/squashes the default or requested resolution into the phone screen,
this is to be able to test unmodified .love files that are not aware of phone stuff.

if you're making a game that is aware of phone stuff,
you can add t.android_native_screen = true to conf.lua to disable this rescaling,
and use love.graphics.getWidth() and getHeight() to get the current resolution, which currently changes depending depending on how you hold the device.
( i'm trying to figure out how to disable this nice but annoying feature atm )
we could also add a orientation-change notification-callback to the love.phone.* custom api if there's interest for that.

I really want to test this on my bottom of the line Android phone. Is there a sample project I can try rather than this one which might be a bit too much? Time to do some research.

Edit: Okay.. well it's running. But it won't recognize the sample project I put in the folder it expects:

Code: Select all

function love.load()
  x = 0
end

function love.update()
  x = x + dt * 100
  if x > 300 then x = 0 end
end

function love.draw()
  love.graphics.circle("fill", x, 100, 30)
end

I'm not sure what I'm doing wrong. I get the blue screen with the logo and the titlebar but I can't load any projects?

[ghoulsblade]

the project must be in your downloads folder or in the sdcard/love/ folder
you might need to create the love folder on your sd card, and copy the .love files there, e.g. sdcard/love/mygame.love

much of the api isn't implemented yet, including love.graphics.circle try drawing images, that should work

try the demos on the love2d.org main website first :
https://bitbucket.org/rude/love/downloads/demos.zip
a bunch of them still have issues (like particle system, physics and fonts), but at least the clouds demo should work well.

also worth a try, even if it still has font problems (damn power-of-2 image size)

Well that's misleading because I put it in a folder called love inside a folder called sdcard inside a folder called mnt.

Now I moved the LOVE folder to the root of the SDCARD and it works... well, it shows it.

I'm not getting a circle on the screen though. Gonna check out the samples.

[ghoulsblade]

i updated the apk, now it shows info including full file paths if no games are found =)

[Jasoco]

Well, the sample projects do semi work.

Passing clouds works the best.

Lovalanch doesn't work at all. (No Box2d yet?)

Particles also has no particles.

Sinescroller has no font, but it works fine. Slower than the computer and no audio, but it sines.

And NO works pretty well. Audio works great. But it's slow on switching screens and not responsive much.

But hell, it works!

Now to try and make my own working project to show my friend at work. He wants to look into programming and I suggested Löve and told him about Mari0 being programmed in Löve. To show him something I made myself and that he could get to work on his own Android (I'd be curious to watch something I made on both devices and how different they are. Mine is a low-end Android, his is the mid-end version of the same model and much better so...)

Next, let's get this on iOS so I can do the same thing on my iPad.

OH, by the way. You should look into implementing DropBox support so we can keep projects there and edit them from our computer and not have to keep switching between USB Disk mode and Phone mode or swapping SD cards.
