Lua Convince Creatues does not consider enough room

[Sytoxian]

Hey,

i created a simple spell to summon a monster:

function onCastSpell(cid, var)
   local summons = getCreatureSummons(cid)
   if(table.maxn(summons) < 2) then
     bomb_health = ((getCreatureMaxHealth(cid) / 100) * 60 )
     position = getCreaturePosition(cid)
     creature = doCreateMonster("Water Healer", position)
     doConvinceCreature(cid, creature)
     setCreatureMaxHealth(creature, bomb_health)
     doCreatureAddHealth(creature, (getCreatureMaxHealth(creature) - getCreatureHealth(creature)))
     doChangeSpeed(creature, -(2000 - getCreatureSpeed(cid)))
   else
     doPlayerSendCancel(cid, "You can only summon two creatures.")
   end
return true
end

But it does not consider the space around the player. When i cast this spell while im stucked somewhere i get this error message:

I get the same error message when i cast the spell while the player is surronded by magic fields.

So i need a way to check if there is enough space and there are not too mouch magic fields arround the player. But i dont know how!

Thanks.

Why i can not spawn a creature while the player is surrounded by magic fields?

You can add those lines into your script and check if it will work.

local playerpos = getCreaturePosition(cid)
local pos = getClosestFreeTile(cid, playerpos)
creature = doCreateMonster("Water Healer", pos)
