how to enable user interactivity

Hello everybody!
I think it is easy ,but i’m a beginner
all i need is to allow the player to click on an object and move it toward another object during playing
and the game notifies the player if he puts the object in the right location or not
Thanks a lot

You could use this to allow the player to pick up the object:

As for notifying the player if he put it in the wrong place or not, use a trigger. On Overlap, check if it’s the object, and if so, notify the player.

I am really grateful for your answer ,thank you.
