How do I code touch movement that works

I made it so that when I (mouse/touch) is touching the player then the new position will be where I drag the player. The thing is that when I drag the player, it sometimes slips off and makes me drag it slower instead of making drastic movements. I tried is touching. It becomes smooth but the player can teleport anywhere I choose. Which I don’t want. I want to drag the player and not let it teleport.

It's hard to tell what your are doing wrong without seeing your project.
