love-android-sdl2 (native, 0.9.2)

Post by fysx » Tue Jan 14, 2014 8:47 am

Hi everyone,

as some of you may have heard I have been tinkering with an native port. It is based on slime's fantastic GLES port and uses the 0.9.1 API. As it is a native port with only little code changed pretty much everything should work. However there is no guarantee but should "just work" most of the time.

The code is available here:

http://bitbucket.org/MartinFelis/love-android-sdl2

You can get the latest Android package from:

https://bitbucket.org/MartinFelis/love- ... /downloads

Current issues:

https://bitbucket.org/MartinFelis/love- ... tatus=open

Differences to the standard LÖVE:
* It uses GLES which requires different shaders and also the graphics module has a slightly different architecture than standard LÖVE on the engine side (but not API wise!). There might linger some hidden bugs there.
* love.system.getOS() returns "Android"
* features multitouch functions love.touchpressed (id,x,y,p), love.touchreleased (id, x, y, p), love.touchmoved (id, x, y, p)
* back button is assigned to the "escape" key
* text input: use love.keyboard.setTextInput(true) or set keyboard position using love.keyboard.setTextInput(enable, x, y, width, height)

Quickstart to get your game running
* Extract your game to /sdcard/lovegame such that main.lua is located at /sdcard/lovegame/main.lua.
* Run the app

Detailed instructions on packaging can be found here: https://bitbucket.org/MartinFelis/love- ... /wiki/Home

Some limitations:
* Requires at least Android 2.3.3

Enjoy!

Changelog:

- Added slime's bugfix for ParticleSystem:clone

0.9.2 (2015-04-10):

- fixed battery drain by properly pausing OpenAL device
- fixed printing of non-number and non-string values
- fixed compilation of Android NDK r10
- fixed compilation warnings concerning APP_PLATFORM
- old instance is shut down when opening a new game (note: it may crash when opening games at a high frequency, e.g. more than 2 per second)
- updated OpenAL-Soft to version 1.16.0
- updated to newer SDL version (f9244b2a151)

0.9.1b:

0.9.1a:

Great work! All modules are supposed to work ?

And how multitouch is working, did you add new callbacks ?

Yes.

Yes, Pavol Rusnak added code for that. The actual code at https://bitbucket.org/MartinFelis/love- ... ter#cl-173 should get you started.

Currently slime is working on a proper touch module. I will most likely to switch to that sooner or later.

Hole crepe, this looks great! I might actually release my game for Android too at some point now. I didn't think this day would come.

Too bad I don't use Android myself anymore though :P

I tested it on my little brother's adriod phone and the no game screen was fully working.

Also is love.mouse counting as the touch thing?
