Cursor problem

[ArmyOfTwo]

Hi, i am very beginner in lua!

function ShowBuilding( )
local sx,sy,x,y,z = getCursorPosition ( )
local object = createObject (3596,x, y, z+299, 90, 0, 0)
       ox, oy, oz = getElementPosition(object)
       gz = getGroundPosition( ox, oy, oz )
createObject (3596,x, y, gz, 90+90, 0, 0)
destroyElement( object )
end

It creates the object but in wrong x, y coordinates! When i drive around where it's supposed to be created its competely in different location than my cursos was! Please help me!

You don't need to create an object then get its position and then get ground possition. Just use getGroundPosition( x, y, z ). When is this function called?

The problem is that if i don't use it like that , the object gets created under the ground!
