LuaJIT and TNTParticlesEngine

edited March 2014 in Bugs and issues
Hi!
I'm trying to use awesome TNTParticlesEngine with awesome LuaJIT and got this:
"03-21 17:51:30.639: D/Gideros(21836): source/tntparticlesengine.lua:1100: attempt to index global 'arg' (a nil value)"
At line 1100 we have:
1099 function CParticles:setSpeed(speed, ...)
1100 local speedMax = arg[1]

It seems something wrong with LuaJIT because it's working well on regular Lua in Gideros Player.

Thanks.

    @Artiom yep, luajit runs under other lua standard, which does not automatically create arg variable.
    in each function that has ... as arguments passed, you need to create it your self like this:
    local arg = {...}
    Hint, hint @GregBUG :)
  • @Artiom, @ar2rsawseen
    yes :) !!!! update coming soon :)

    Thanks, @GregBUG but I already fixed this :)
    I have a bug when I create hidden emitter or hide it later:
    source/tntparticlesengine.lua:308: The supplied Sprite must be a child of the caller.
    stack traceback:
    source/tntparticlesengine.lua:308: in function source/tntparticlesengine.lua:278
  • @Artiom

    so i can fix.

  • Hi @GregBUG

    Maybe this can help you fix your nice TNTParticle
    I tried LuaJiT with demos of TNTParticle and these demos isn't working as before:

    demo 4
    demo 5
    getting_start_1

    Finally, I don't remember as was working TNTParticle before, I only remember some demos. I hope this can help you in something.

    P.S.
    @Artiom yep, luajit runs under other lua standard, which does not automatically create arg variable.

    @ar2rsawseen, you are right
  • @GregBUG,

    local fireParticle = CParticles.new(particleTexture, 20, 0.3, 0.6, "add")
    fireParticle:setSpeed(220, 320)
    fireParticle:setSize(0.1, 0.1)
    fireParticle:setColor(255,110,80)
    fireParticle:setAlpha(0)
    fireParticle:setRotation(0, -160, 360, 160)
    fireParticle:setAlphaMorphIn(240, .15)
    fireParticle:setAlphaMorphOut(50, .9)
    fireParticle:setSizeMorphOut(0.8, 0.9)
    fireParticle:setSpeedMorphOut(450, 1, 450, 0.5)
    fireParticle:setColorMorphOut(110,110,110,1.2,20,20,20,1.5)

    local fireEmitter = CEmitter.new(37.5, 0, 90, fireSprite)
    fireEmitter:assignParticles(fireParticle)
    fireEmitter:start(true) --start hidden, error here

  • @Greg, Xojo would be a better option, as you could also make it a web service hosted on your servers (if you want and have the Enterprise License)
