Within Start() I am instantiating a prefab several times along the z axis . I.e. the z-position is increased for each new instance of the prefab. Strangely the LAST instance is instantiated at the FIRST z position when I start the game.
In Start() I am running this loop
Within the function CreateParcel() the z position is increased, an instance of the prefab is instantiated at this z position and the name of the instance is changed (
When I log the data with
Log results: Instance 1: (0.0, 0.0, 5.0) Instance 2: (0.0, 0.0, 10.0) Instance 3: (0.0, 0.0, 15.0) ... Instance 7: (0.0, 0.0, 35.0)
But when I check the instances in the scene hierarchy, the instances don't match this sequence. When I check the position of the different instances with the Inspector it is the following sequence:
Inspector results Instance 1: (0.0, 0.0, 10.0) Instance 2: (0.0, 0.0, 15.0) Instance 3: (0.0, 0.0, 20.0) ... Instance 7: (0.0, 0.0, 5.0)
That is ... (the logged) instance 7 is not at the end of the sequence as it should be and as the log said, but it is in the first position of the sequence. Where does this difference come from? Or is there any silly error in my thoughts/script?
I think your confusion is coming from the fact that you're renaming the prefab each time, rather than renaming the instance of the prefab that was just created.
This means that when you set the name, you're affecting the name of the next instance to be created, rather than the one that was just instantiated!
You're currently not getting a reference to the instance that was just created. The Instantiate function returns a reference to the object it just created, so you need to pipe this into a variable of the correct type.
To fix this, you'd need to change the 2 lines in "CreateParcel" to this:
I'm assuming your prefab variable's type is "GameObject". If it's something else like "Transform", change the types in the code above to suit.
Once you've done this, your mystery should be solved :)
