Lua Player TODOs

Zenurb · Post by **Zenurb** » Fri Sep 30, 2005 9:01 am

Is there anywhere where I can find future features for Lua Player? I looked at the functions documentation and it seems pretty limited and was wondering if there was going to be any improvements in the near future / what is planned.

with those functions you can do quite a lot;
note: default functions for lua are also supportet (eg. math library!)

There is no central place for future features, but the Lua Player core development thread lists some of it. I would like to have theses features:

- OpenGL
- 2D vector graphics library for image scaling, roatating, vector drawing etc.
- PhysicsFS filesystem
- Windows/Mac/Linux port with full support of all Lua Player functions

Currently I'm working on the OpenGL support and Laurens is working on the PhysicsFS filesystem. OpenGL delays a bit, because there are still major problems with the pspgl library, so when I have some time, perhaps I'll implement the 2D vector graphics lib first. My test with libart was that it is too slow (http://forums.ps2dev.org/viewtopic.php?t=3245), I'll try Cairo or perhaps the eyeGT lib, but I prefer open source libs.

Ooh. 2D vector graphics would be really really sweet to have!

Not to nag or anything, but how bout that sound.beep(), are you going to add something like that?

LuMo · Post by **LuMo** » Sat Oct 01, 2005 7:14 pm

haggar, this can be easily implemented by playing a beep.wav file...

I asked Nevyn to to it, because he has done all the mikmod integration, I hope he hasn't forgot it :-) It would be a general feature to play sound from selfmade Lua arrays.

I'm really busy nowadays, I haven't had time to write a single line of PSP code in quite a while :( My personal todo list when I finally get time again is:
- Fix the Sound.load bug (crash on invalid filename)
- Fix sound loops not working properly (being cut >32 voices)
- Playing sounds generated from a lua table
- The Mac version of LuaPlayer
- A new, great Lowser that I've been thinking about for a long time (inspiration from Columns view in Mac OS X)
- A LuaPlayer library for cooperative multitasking, clipping regions (windows), cursor, "mouse" and keyboard events, and stuff like that.
- Perhaps implement a more competent sound library, or at least re-port mikmodlib to mac and win.
- Prepare the presentation for EuroOSCON :P (which has an actual deadline :O )

I was only looking at the PSP spesific stuff I think.

OpenGL support sounds amazing, But yes I am hoping for a good version of windows / linux Lua Player to be released soon (in SDL perhaps?)

It would be good if you guys could give us some updates regularly how everything is going, do you have a developer blog or something? =D

OpenGL would be my dream for LUA, all the semi transparent PNG's could have a perpose too! keep up the good work shine and nevyn, this is an incredible start to a godly programming language!

Zenurb · Post by **Zenurb** » Mon Oct 03, 2005 11:37 pm

OpenGL and some good MP3 / Mpeg support Is what I'm really looking forward to.

oh, i just thought of some good stuff, Image removing (might already be possible) like clickbutton.remove(), another is labels, this would be much better than screen:print() because you could create text in a label, and remove the label from the screen with ease, or change the text in a label. thats my want list (and the stuff in my post above ;))

Removing images from the drawn canvas? can't do that.
Removing images from memory? already done by garbage collection.

Images with labels? Easilly implemented as a new class in Lua.

LuMo · Post by **LuMo** » Tue Oct 04, 2005 5:54 pm

hmm i think he did not mean images with labels
thinking of java and delphi
they got label objects
which hold some data like
x,y, font, text aso...
but also this can be implemented using lua (easier than in c++)

Removing images from the drawn canvas is impossible, it's already written to the PSP screen. (I assume)

What you can do is stop the image from being blit on the next screen.flip()

I would like to have a way to change the clock speed of the PSP (e.g. 333MHz)
I would also like to be able to use stereo WAVs.

it has already been stated that they will not put a clock speed changer in it because they want all Lua programs to be safe. They also won't add a boot EBOOT function either
