|PlayN 1.6 released||Michael Bayne||3/5/13 12:22 PM|
Hello makers of games,
I'm happy to announce the release of PlayN 1.6 (and Triple Play 1.6). Release notes can be found at the usual places:
This release includes two changes to the way that projects are organized, and anyone upgrading from 1.5.x (or earlier) to 1.6 will need to make some changes to their project organization. The following wiki page describes these two changes and how to adapt to them in your project:
In addition to a number of bug fixes and performance improvements, this release includes some useful new features:
- tinting for layers (on GL backends only)
- HtmlAssets.ImageManifest which makes it easier to "port" an Android or iOS game that assumes synchronous image loading to HTML where synchronous image loading is not possible
- HiDPI support for HTML backend (also useful when "porting" a HiDPI iOS and/or Android game to HTML)
If anyone finds any errors in the migration guide, please let me know.
Thanks and happy game making,

I hope Tinting shader isn't consuming too much additional performance.

just tried this failed... it said it couldnt find the -assets.jar, probably my fault, so i just backed up my project and created a new one with the same names and copied stuff in the appropriate places to the new project, took a lot less longer than following this guide ;-)

At the same time, it now includes alpha (in addition to RGB tint) per vertex, which means that if you render the same image with different alpha levels, the shader does not need to be flushed in between. Before the alpha level was a uniform attribute, so if you switched alpha levels, the shader had to be flushed.
For projects that use texture atlases and complex animations, this change probably yields a net performance gain. That was the original motivation (include alpha per vertex to improve performance), and I decided to go whole hog and include tint as well.
This also opens the door to consolidating the texture shader and color shader, which I'd like to do. That will allow us to avoid flushing and switching shaders when one switches from textured quads to plain-filled quads. That will definitely improve performance for games that use user interfaces with blocks of solid color.
If you wire up the TriplePlay HUD you can get a lot of useful information on how the PlayN rendering system is performing:

I have just updated to 1.7-snapshot, and my old 3mb audio files doesn't work anymore, what is the current limit for audio files?

Assuming you mean the Java platform, big sound files used to not be supported, then we hacked in some stuff to support them but it was causing problems in some cases.
Then I changed a bunch of stuff on Android that necessitated adding Assets.getMusic() in addition to getSound(). So I made the Java backend use the somewhat problematic code (BigClip) for getMusic() and the old "doesn't support big files" stock code (Clip) for getSound().
So if you're loading music, use getMusic(). And if your SFX are 3MB then you are crazy.

Thanks, I didn't know about new getMusic method

The Android backend was using a streaming sound API for playing SFX which was wacky and made horribly poor use of the OS sound resources.
