problem with variable and position

[poe6man3]

local function getTargetPosition(creature)
    local targetPos = creature:getTarget():getPosition()
    print (targetPos.y)
    local targetNorthPos = targetPos
    targetNorthPos.y = targetNorthPos.y - 1
    print (targetPos.y)
    local targetSouthPos = targetPos
    targetSouthPos.y = targetSouthPos.y + 1
   
    targetNorthPos:sendMagicEffect(50)
    targetSouthPos:sendMagicEffect(30)
end


function onCastSpell(creature, variant)
    getTargetPosition(creature)
end

Can somebody tell my why variable targetPos i being changed when i created new variables which holds the position of the main variable and making changes to the new ones ?

Long story short, because it's a table.

You need to create a new position, with the information from targetPos instead of calling targetPos directly.

local function getTargetPosition(creature)
    local targetPos = creature:getTarget():getPosition()
    
    local targetNorthPos = Position(targetPos.x, targetPos.y, targetPos.z)
    targetNorthPos.y = targetNorthPos.y - 1

    local targetSouthPos = Position(targetPos.x, targetPos.y, targetPos.z)
    targetSouthPos.y = targetSouthPos.y + 1
    
    targetNorthPos:sendMagicEffect(50)
    targetSouthPos:sendMagicEffect(30)
end


function onCastSpell(creature, variant)
    getTargetPosition(creature)
end

Or if you want the script shorter...

local function getTargetPosition(creature)
    local targetPos = creature:getTarget():getPosition()    
    Position(targetPos.x, targetPos.y - 1, targetPos.z):sendMagicEffect(50)
    Position(targetPos.x, targetPos.y + 1, targetPos.z):sendMagicEffect(30)
end


function onCastSpell(creature, variant)
    getTargetPosition(creature)
end
