ok, I guess the "object" is a prefab, so when you create the object, you want it to randomly appear?
is that correct?
first of all, where is the array variable resides? is it on the object prefab or is it somewhere on the scene?
the easiest scenario is the array variable is reside on the object itself, then you can do this:
1. Get random array and save it into your v3 variable (Retrieve the v3 value from array)
2. Then set position UserOwner to v3 variable
3. Done
If the object is a prefab and the array reside on the scene object, then
1. Get random array and save it into your v3 variable (Retrieve the v3 value from array)
2. Create Object, Drag the prefab onto it, set position to V3 Variable
3. Done
Hope it helps
