Table lua: a sequentially ordered list disrupted

Requirements: a table in order to disrupt the order of discharge

Note: This function will modify the original data off the table, because the table is in lua pass references

 

function Table_Rand(t)

　　if t == nil then

　　　　return

　　end

　　local tRet = {}

　　local Total = table.getn(t)

　　while Total > 0 do

　　　　local i = math.random(1,Total)

　　　　table.insert(tRet,t[i])

　　　　t[i] = t[Total]

　　　　Total = Total -1

　　end

　　return tRet

　　

end
