[Release] LuaPlayer Euphoria V3 - Yet More Speed + IntraFont!

[Zack_PSP]

Hola :)

Hey.

So after a bit of work I bring you LuaPlayer Euphoria V3.

New Features, Improvements, Bug Fixes & Changes :

New Features :

1) IntraFont support. You can now load and blit fonts without the huge slowdown the built in font function has :)

How to use it ? Go to Samples/IntraFont for a working usage example.

Improvements :

1) Speed increase. Roughly between 20>40fps.
2) screen:clear() is now faster.

Bug Fixes :

1) screen:clear() now actually works. (it didn't in V2)
2) Image alpha on created images, colors, and loaded images now works.
3) 3D things I broke are now fixed (so 3d wise it is the same as .20 was).
4) FPS counter no longer flickers when not using waitVblankStart().
5) Checking for input (i.e pad = Controls.read()) no longer caps the framerate to 60fps. I suggest you use waitVblankStart() if you need to cap it to 60 ;)

Changes :

Ok, so all of the function names in V1 & 2 have changed. I meant to do this from the beggining but rushed so much I didn't quite get to it. The function names now ring true to the default LuaPlayer naming convention.

Here are the new functions and names (also included in the download) :

You forgot to mention that Color.new() now has alpha support as well (like PGE & HMv2).

---###Color###---
Color.new(r,g,b,a)

--range from 0-255
--alpha is optional & is defaulted to 255(no transparency)

this is awesome

Did I?

Thanks for making it clearer though :)

[dan369]

, no problem zack. Even though most people won't use alpha in colours i still think it's a handy addition :)

As a added note the big 1000 posts

Congrats Dan.

I thought that this was not going to turn into LuaPlayerHM. I was hopeing that this was going to be a luaplayer for developing games, rather then one for app's.

I planned it to be universal.

There still only planned features though. If it's considered bloat I will gladly put it to a vote :)

After all I am doing this for the lua coders not myself, so if they don't want it I wont do it ;)

[homemister91]

Sounds good. Because i really like the luaplayer. It runs very fast and by fixing the 3d it will realy make lua a good language to program in for the psp again.

[michaelp]

I thought that it was gonna be the exact same as the original luaplayer0.20, just with speed enhancements, and be backwards compatible with the luaplayer0.20 code.
But this is good too. :)

I have not tried this out yet, but I will soon. I'm planning on trying this with the newest build of Maelstrom, and seeing what kind of results I get.

And I'm all for a game version and a full-version, or just a game-optimized version. Also, for the game version, I think keeping 3d would be great as long as it does not cause too much of a slowdown.

Thanks.

[nickxab]

this is awesome :icon_bigg

[emcp]

just wondering
how many people have forgotten about PGE LUA

phoenix game engine

also it would be interesting to compare the two in terms of speed etc

btw is that you ZION

[Zack_PSP]

LuaPlayer euphoria needs math optimization before it is fair to compare it to pge ;)

I have learned Lua through the LuaPlayer tuts.
I have been learning alot more about lua via wiki and fourms...etc.
I love the fact you kept the Luaplayer functions.
With Pge and Hm or w/e I'd have to recode my whole game just to achieve the benefits of that interpreter.
Keep updating.
Your work is very much appreciated!!

I havn't tried it yet, but i'm planning to.

That is the plan, I don't want people to have to recode there scripts to use this there are a few new functions that have to be used (2. System.startGu() and System.endGu())) but i cannot see there being any more required functions that differ from the original lua player.

Great work Zack.
I havn't tried it yet, but i'm planning to.

Your welcome :)

Good job man.
