try that.
x = 8.13
math.round(x) = 8
y = 8.52
math.round(y) = 9

:) Great, network :)

Shine's mandelbrot script turned me on, so here my fractal tree demo :


Left of right to generate a new tree.

I love lua !

Thx Shine... i did indeed drop the theScene and everything on screen. Now the screen:clear() works.
Seems weird though that theScene:clear() didnt work.
I'm off to code more ... :)

Well, lol. I managed to get clear working, but NOT in the way it should: it behaves strangely: i had to do a screen:clear() in my main while loop, AND a theScene:clear() in my rotate function that is called just after that, meaning it clears screen, then clears theScene. It doesnt work with one or t...

"confusing tip"...i cannot get clear() to work and that was the only way to get rid of the "press restart" bug in 0.7. I tried all possible ways of clear() with nevyn on IRC. Tried screen:clear(), screen:clear(Color.new(0,0,0)), screen:clear(Color.new(0,0,0,255)) myEmptygraphic:c...

Try that at beginning... i ran into this bug also. -- this to prevent the press start to restart display bug layout =Image.createEmpty(480, 272) layout:fillRect(0, 0 , 480, 272, Color.new(0,0,0)) screen:blit(0, 0, layout&#41...

u can try web lua (lua 4 only) for tiny bits of your code or install Lua Cheia on your pc.

screen:clear() or myemptygraphic:clear() doesnt work for me; nobody uses that, not even you in snake but at newgame ?

F34R, add a fillrect with black color in the main while loop, in order to erase previous smiley

Shine > seems interesting :)
" Libart has full support for RGB and RGBA image operations, including rotation, scaling, skewing, and alpha compositing."

Yay !

F34R, try that: System.usbDiskModeActivate() background = Image.load("background.png") smiley = Image.load("smiley.png") screen:blit(0, 0, background, 0, 0, background:width(), background&...

Shine, Nevin, is it possible to add a function inside LUA to rotate an image ? I've been coding a few functions, like reading the pixels 1 by 1 of a given image, storing the x,y,color in a table, then recreating the image with that array dot by dot, and modifying x,y in that array live applying 2d s...

Hi ... My first contrib to luaplayer. Shine, you missed that in your apps ! So here is the classic 3d wireframe cube demo made on all systems / languages... lua for psp had to have it :) http://lua.ventoline.com/screenshot3dcube.gif Download it here : - full with lua 0.7 embedded - lua script versio...

Ok.. been running a few tests to see what was the fastest loop. Somehow, as usual, it seems that while - is the fastest around. System.usbDiskModeActivate() color = { red = Color.new(255,0,0); green = Color.new(0, 255, 0); blue = Color.new(0,0,255); } local q = 0 local j = 0 local time = os.clock() ...

Excellent .... thx Shine. Lua's doc is really awful and so incomplete. We lack a math.int or math.round .. somehow founded that one, but would be nice to implement directly in lua: function math.round(num, idp) local mult = 10^(idp or 0) return math.floor(num * mult + 0.5) / mult end idp being the n...

Any way to implement a millisecond function in lua ? It really lacks it...
We have os.time(), which returns the time in seconds....
How about a os.timems(), which returns the time in milliseconds ?

Great work Shine on the Lua player :) I started to toy around with it, even if documentation on lua.org website is really bad. Development is easy, but one looses too much time sending to psp / testing / reconnecting psp resending... I ended up testing bits of my code on weblua (http://doris.sourcef...
