How do I instantiate certain objects to appear in a specific spot?

Although the picture below is a little glitchy, I want to be able to instantiate those three cylinders after I click on the object onMouseDown. I want to be able to have those three cylinders in the exact position and alignment as on the object. How do I do that?

Also, how would I return to just the single main object (the tree) if I want to. I’m not sure how to implement something like that either.

Am I supposed to create prefabs and instantiate those?

Thanks!

I think you would use this:

using one of the ones that returns the ‘hit’ information. That will contain the point at which the object was hit, and the normal at that point too in case you need it.

Prefabs are good. That way if you want to change what you are placing there you just change the prefab.

Build your hierarchy like this:

Tree
  Cylinders
    Cylinder1
    Cylinder2
    Cylinder3

Then put a collider on the Tree. This will define what you can click. You get most precision if it’s a mesh collider, but maybe a capsule collider is enough - you decide.

Cylinders is an empty gameObject(CTRL+SHIFT+N)

Then add the ClickSwitch MonoBehaviour to Tree and drag Cylinders in the obj reference and you’re good to go.

public class ClickSwitch : MonoBehaviour {
    public GameObject obj;
    void OnMouseDown() {
        obj.SetActive(!obj.activeSelf);
    }
}

I think this is probably already answered, but if not. have you thought of doing like a instiate object on collision, and have that as the place to instiate at. or do a on collision and have that as the game object to setactive
