How to "getpos"

[ziggy46802]

Here is my script for mining a crystal

function onUse(cid, item, frompos, item2, topos)

bigrock = 8634
smallrock = 8638
posa = {x=1049,y=1062,z=8}                                                                                        	--set position	
chance = math.random(0,100000)
brake = math.random(0,100)
mining = (getPlayerSkill(cid, FIST_SKILL) * 3)

function goto(cid, item)
	addEvent(restore, (1000 * 60 * 54),(1000 * 60 * 131) , cid) 
	--addEvent(restore, 5000,10000, cid) --test mode
	return true
end

function restore(cid, item1, item2)
		doRemoveItem(getTileItemById(posa, smallrock).uid)         
		doCreateItem(bigrock,posa)	                              
		doSetItemActionId(getTileItemById(posa, bigrock).uid, 4001) 												--set AID
			return true
end	

if item.itemid == bigrock and getPlayerItemCount(cid,2553) >= 1 and getPlayerSkill(cid, SKILL_FIST) >= 1 then                               
			doPlayerAddSkillTry(cid, SKILL_FIST, 10)
			doRemoveItem(getTileItemById(posa, bigrock).uid)
			doCreateItem(smallrock,posa)	
			addEvent(goto, 1, 2, cid)                               
			doSendMagicEffect(getPlayerPosition(cid), 13)
			
if brake > mining then
	doPlayerRemoveItem(cid, 2553, 1)
	doCreatureSay(cid, "Well shit, your fuckin pick broke man.", TALKTYPE_ORANGE_1)
		return false
	end	

if chance >= 0 and chance <= 50000 then
	doPlayerAddItem(cid, 2255,1)
	doCreatureSay(cid, "You found some trashy copper.", TALKTYPE_ORANGE_1)	
		return false
	end

if chance >= 50001 and chance <= 80000 then
	doPlayerAddItem(cid, 2254,1)
	doCreatureSay(cid, "You found some dirty copper.", TALKTYPE_ORANGE_1) 
		return false
	end

if chance >= 80001 and chance <= 95000 then
	doPlayerAddItem(cid, 2253,1)
	doCreatureSay(cid, "You found some dull copper.", TALKTYPE_ORANGE_1) 
		return false
	end
	
if chance >= 95001 and chance <= 100000 then
	doPlayerAddItem(cid, 2252,1)
	doCreatureSay(cid, "You found some decent copper.", TALKTYPE_ORANGE_1) 	
		return false
	end	
		return true
	end
		return true
	end

at the top for "posa", do I have to put that in for each and every crystal I put down, each one a different position, or is there some type of function that can like... "get pos from used item" or something like that so that I dont have to type in the coordinates every time and mess up every once in a while.

use frompos or topos
instead of getTileItemById(posa, bigrock).uid you can use item.uid
