coordinate picker help

I need a levelgen that can pick x number of coordinates out of y number of coordinates, and feed them into the following


Right now I have this.

  Code:

-- five each: resource items, repair items, energy items, test items
-- their position in the maze should be randomized from coords
local repair = RepairItem.new
repair:setRegenTime(20)
local energy = EnergyItem.new
energy:setRegenTime(20)
local resource = ResourceItem.new
local bouncy = TestItem.new


 

  Code:

3442.5 1912.5 20
2932.5 2422.5 20
2422.5 2932.5 20
2422.5 2422.5 20

I'm thinking 20 coordinates are all I need (that isn't set in stone) - I have too many and need a picker
I'm actually not sure how I'll put these coordinates into the level either
bad case scenario I do this
energy1:setPos
bf:addItem(energy1)
energy2:setPos()
bf:addItem(energy2)
energy3:setPos()
bf:addItem(energy3)
energy4:setPos)()
bf:addItem(energy4)
energy5:setPos()
bf:addItem(energy5)

repair1:setPos()
repair2:setPos()
repair3:set... etc
(yeah that would suck)

worst case scenario I just put them in in set places, every time. sure would be easier

Yo. Check it.

  Code:

pickerList = {
    point.new(3442.5, 1912.5),
    point.new(2932.5, 2422.5),
    point.new(2422.5, 2932.5),
    point.new(2422.5, 2422.5),
    point.new(3442.5, 2422.5),
    point.new(3442.5, 2932.5),
    point.new(1912.5, 1912.5),
    point.new(2422.5, 1912.5),
    point.new(2932.5, 1912.5),
    point.new(3952.5, 1912.5),

thanks . u cam c in pleaides, ,mazeattacker
