Hey everyone. So I have been working on a update for LuaPlayer 0.20. Not for long but a few major changes that result in a huge speed boost.
I will take the rest from the readme files :
What is LuaPlayer Euphoria ?
LuaPlayer Euphoria is a branch of LuaPlayer that is optimized for speed, Whilst staying true to
the ease of use and function names we have all grown to love.
What can it do? What makes it different to the normal LuaPlayer ?
It can display images up to 100%+ faster than
the default LuaPlayer, by automatically swizzling the images as there loaded.
It also features Mp3 support. This is done on the main processor for now. Don't worry however, this is a optimized mp3Player.
Whilst displaying a 480x272 image and playing a Mp3 file, LuaPlayer Euphoria can achieve
up to 228 FPS (Frames Per Second) running at only 222mhz!. (SEE SAMPLE DEMO FOR PROOF!)
It also features CPU Speed control. Which can be done by the user. So you can set the PSP's CPU to either : 100, 222, 266 or 333mhz.
Another feature, albeit trivial, is a built in FPS Function. By simply calling "showFPS()" you can see your game/applications
current FPS out of 60 frames. If you want to see its "True" FPS, comment out screen.waitVblankStart and pad = Controls.Read() - as these
cap the framerate to 60.
The last feature (so far) is the ability to properly free images. I don't know if this worked before but anyway...
Simply call "freeImage(myImage)" (with myImage being the image you want to free) and it will remove the image from memory.
It goes without saying that you should not be displaying the image your trying to free at the time of freeing it.
+ A lot more to come!
It is slim and phat compatible. Should work on 1.0>5.xx firmwares. Should also work
Why use this over PGE or LuaPlayer HM ?
Well thats a good question. If you don't like the way PGE lua or LuaPlayer HM are set up (ie function names, calls)
and prefer the old lua player in that sense (just not the performance), then LuaPlayer Euphoria is the answer
you have been looking for.
Where can I find the new functions list?
In the download see the "Functions & Features" text file.
Has all the usual function names changed?
No and they never will. Even with new features I am trying to keep
the naming convention and required function calls to a minimum. After all no-one likes having to call 4>6 functions just to initialize the graphics now do they
Are we going to see more in the future ?
Provided there is genuine interest from a decent sized group of people then yes. I wont be doing this
for the good of my health... lol.
So yeah, if there are enough people using it, and enough people interested in the project I will keep working on it.
I will also try my best to add any new features you desire.
If you would like to request a feature be added, please do so at the official forum : LuaPlayer Euphoria Forum
