How to create an object along the line of the finger?

Question

Unity

Good day, friends. How to create a line (platform or any object) based on the coordinates of a finger on the screen? I want the player to create a line (object) of the same length and shape as he swiped his finger after swiping the player's finger. Can you please tell me how to do this or have some examples? The screenshot showed an example of a drawn line. How to create an object that is shown as a white line in the screenshot, based on the fact that it was drawn by the player?
Thank you very much in advance!

Answer 1

Read the documentation - everything is written there. If an algorithm is needed:
Handles the finger movement event
Stores the coordinates of the finger
Normalizes, inter/extrapolates the coordinates.
If necessary, we translate the screen coordinates into game coordinates.
