lua matrix bug on android

alexzheng

hi
I'm working on a tetris game these days and I use matrix from http://lua-users.org/wiki/LuaMatrix.
It work well on giderplayer,however,after export to android project and run in my nexus s,it just show a white screen.
I make sure this is caused by the matrix by add the following code to the jumping ball's main.lua
local matrix = require 'matrix'
m1 = matrix{{8,4,1},{6,8,3}}
m2 = matrix{{-8,1,3},{5,2,1}}
assert(m1 + m2 == matrix{{0,5,4},{11,10,4}})

and it also show a white screen in my nexus and it work well after removing these lines.

I suspect from the require command. You shouldn't use it. Lua files are executed automatically when the application starts.

how can I use matrix function without local matrix = require 'matrix'

atilim

Just add the matrix.lua and to your project. If a Lua file is dependent to it, add a dependency from "Code Dependencies" window by right clicking the Lua file.

I have already tried this,it does not work.
staticBox.lua:54: attempt to call global 'matrix' (a nil value)
stack traceback:
staticBox.lua:54: in function 'makeNextBox'
gamePlay.lua:86: in function 'nextBox'
gamePlay.lua:73: in function 'setupBox'
gamePlay.lua:41: in function 'init'

You're right You need to remove the local keyword at line 117 in matrix.lua:

117 local matrix = {_TYPE='module', _NAME='matrix', _VERSION='0.2.10.20111203'}
