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

[Zack]

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) :

how do you use this? it is very confusing.. there's always an error null or system error

[osgeld]

just like normal luaplayer, write script save as index.lua and go

(course this is in the instructions that come with the package)

System.startGu()
im = Image.createEmpty(480,272)
im:fillRect(16,16,256,256,Color.new(0,255,0))
System.endGu()
repeat
 System.startGu()
 screen:blit(0,0,im)
 System.endGu()
 screen.waitVblankStart()
 screen.flip()
until Controls.read():circle()
screen:save("ms0:/swizz.png")
System.quit()

Here is the correct way (or working way at least) to do it :

im = Image.createEmpty(480,272)
im:fillRect(16,16,256,256,Color.new(0,255,0))

while not Controls.read():circle()
 System.startGu()
 screen:blit(0,0,im)
 System.endGu()
 screen.waitVblankStart()
 screen.flip()
screen:save("ms0:/swizz.png")
end
System.quit() 

You only need to start the gu and end it in your main loop. Only during blitting. Not loading too

Sorry I suck at documentation ( I don't put enough effort into it).

Hopefully someone will help me with the documentation and samples at some stage
