How do I de/activate a gameobject of the hierarchy ingame?

Hello,
As I couldn't find any working scripts on how to pick up objects, I want to know how I can activate an object which is already on my hand but invisible and deactivate the object I'm colliding with (deactivate item on the ground and activate it on the hand)

 

Your first problem should of been easily fixed..?
Is your OnTriggerEnter working correctly?

But to answer your new question...
You can activate/deactivate a gamobject like so:

Code (csharp):

1. GameObject.SetActive

For example:

Code (csharp):

1. gameObject.SetActive(false);

therefore you just need a reference of the gameObject you want to active/deactivate.

NOTE: you still need your OnTriggerEnter to work correctly to be able to deactivate that object.
I would also add a tag, to be sure it's a pickable item or not.

Code (csharp):

1. void OnTriggerEnter(Collider collider)
2. {
3.     if(collider.tag == "pickable")
4.     {
5.         print(“this is working!”);
6.         collider.gameObject.SetActive(false);
7.     }
8. }

Log in the condition to be sure your Trigger is actually working.

 

Thanks it works!
But I'll post something later maybe because of the other gameObject which should appear

 

Everything works except that the gameobject I want to carry around doesn't follow me.
Can you help me?

 

@xSiraxXx, what are you doing for the object to follow you?
You could always change the parent of the picked object so it's now a children of your player.

Code (csharp):

1. void OnTriggerEnter(Collider collider)
2. {
3.     if(collider.tag == "pickable")
4.     {
5.         collider.gameObject.transform.parent = player.transform;
6.     }
7. }

 

Thanks it works ^^

 

Glad it does
