Create Object "Tiledbackground" at pointa.x, pointa.y, set angle to angle(pointa.x,pointa.y,pointb.x,pointb.y), set height to 1, set width to distance(pointa.x,pointa.y,pointb.x,pointb.y)

You have example? because i need to know at what point he touched.

Example: goo.gl/CG9mK4

does the player have to touch both points or will it automatically draw a line to the point with the next higher number?

The player will automatically draw a line to the point

you could pick the first dot by an event "pick nearest dot to touch.x, touch.y"
