Player location check.

[Torrix]

Is it possible to check if a player exists at specific location, in relation to your character? For example, I would be player x:

0 0 0 0 0
0 0 0 0 0
0 0 x 0 0
0 0 0 0 0
0 0 0 0 0

In this area, I want to check if any of those zeroes around me is actually a player.

 

[OTx]

function getCreaturesInRange(position, radiusx, radiusy, showMonsters, showPlayers, showSummons)
	local creaturesList = {}
	for x = -radiusx, radiusx do
		for y = -radiusy, radiusy do
			if not (x == 0 and y == 0) then
				local creature = getTopCreature({x = position.x+x, y = position.y+y, z = position.z})
				if (creature.type == 1 and showPlayers) or (creature.type == 2 and showMonsters and (not showSummons or (showSummons and getCreatureMaster(creature.uid) == (creature.uid)))) then
					table.insert(creaturesList, creature.uid)
				end
			end
		end
	end

	local creature = getTopCreature(position)
	if (creature.type == 1 and showPlayers) or (creature.type == 2 and showMonsters and (not showSummons or (showSummons and getCreatureMaster(creature.uid) == (creature.uid)))) then
		if not(table.find(creaturesList, creature.uid)) then
			table.insert(creaturesList, creature.uid)
		end
	end
    return creaturesList
end

Add this in your libs/050-functions.lua or just put it as local function in your script

usage ex:

function onUse(cid)
	if(#getCreaturesInRange(position, radiusx, radiusy, showMonsters, showPlayers, showSummons) > 1) then -- Checks if there is more than 1 player/monster/summon in position
		print("Yes")
	end
	return true
end
