How to automatically perform object/building creation

This example shows you how to easily verify if any object model ID is non-dynamic, so it can be used with the createBuilding function, as long as it's outside within the map boundaries. This script will only work CLIENTSIDE due to createBuilding.

function createObjectOrBuilding(modelID, x, y, z, rx, ry, rz, interior, dimension)
    -- Dynamic object models will always have a physical properties group different than -1.
    local isNonDynamic = engineGetModelPhysicalPropertiesGroup(modelID) == -1
    -- Buildings can't be placed outside dimension 0
    local isNormalDimension = dimension == 0
    -- Buildings can't be placed outside regular map boundaries
    local isInsideMapLimits = x >= -3000 and x <= 3000 and y >= -3000 and y <= 3000

    local obj, bld
    if isNonDynamic and isNormalDimension  and isInsideMapLimits then
        bld = createBuilding(modelID, x, y, z, rx, ry, rz, interior)
        assert(bld, ("Failed to create building with model ID %d at %f, %f, %f in interior %d"):format(modelID, x, y, z, interior))
    else
        obj = createObject(modelID, x, y, z, rx, ry, rz, false)
        assert(obj, ("Failed to create object with model ID %d at %f, %f, %f"):format(modelID, x, y, z))
        setElementInterior(obj, interior)
        setElementDimension(obj, dimension)
    end
    return obj or bld
end

-- This would be your object's model ID
local modelID = 3556
-- This would be your object's position coordinates
local x, y, z = 0, 0, 69
-- This would be your object's rotation coordinates
local rx, ry, rz = 0, 0, 90
-- This would be your object's interior ID
local interior = 0
-- This would be your object's dimension ID
local dimension = 0

-- We use pcall to catch any errors that createBuilding may throw
-- (it's the only new function that can error, although with these verifications it should never happen)
local success, element = pcall(createObjectOrBuilding, modelID, x, y, z, rx, ry, rz, interior, dimension)
if not success then
    outputDebugString(("Failed to create object or building: %s"):format(tostring(element)), 4, 255, 25, 25)
    return
end

-- OPTIONAL: Then you can apply additional properties, like so:
if getElementType(element) == "object" then
    setObjectScale(element, 1.69)
    setObjectBreakable(element, false)
end
setElementAlpha(element, 255)
setElementCollisionsEnabled(element, true)
setElementFrozen(element, false)
