Lua Spell attack issue

Hey guys, for some reason, my servers Spells attack players regardless of if you target another player. What do I need to add to my spells to ensure they require a target before attacking players?

E.G:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_ENERGYHIT)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -1.8, -0, -1.9, 0)


local arr = {
{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0},
{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0},
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0},
{1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
{1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1},
{1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0},
{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0},
{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0},
{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
}


local area = createCombatArea(arr)
setCombatArea(combat, area)

function onCastSpell(cid, var)
return doCombat(cid, combat, var)
end
