How instantiate object in the specific time?

Hi, does anyone here know how to instantiate a gameobject at a certain time?
for the example I have 2 object (Object A and Object B), I want to instantiate Object A at the 5 second, and I want to instantiate Object B at the 10 second in the position of Object A and destroy or disable Object A.

This isn't a 2D question... but I bet many people here know how to do this; you are listing several tasks that are pretty easy on their own. Instead of asking, maybe you should google the steps and then figure those out yourself?

- Wait for a specified time
- Destroy/SetActive object
- Instantiate or SetActive a new object

Timer can be created using a variable that you add to in Update until it is full or use a Coroutine or InvokeRepeating for similar thing.

 

I'm sorry, I'm new in unity forum, but thank you for the advice.
