Allow objects to be dragged in-game with mouse?

I know this is not a request site, but I cannot find anything about this topic online that fits my needs.

I am in need of a system/script that allows when a player clicks (holds) an object, they can drag the object around, like in Lumber Tycoon 2. All I need is a way for players to hold click on an object and drag it around (nothing else). Again, I tried looking online but only find ways to move objects with only the x-axis and not the y-axis. I do not need scripts, just need to be pointed in the right direction. Thank you in advance.

The link above does relate to my problem, I looked at the answer and do not know how to apply it and use the scripts provided.
