Get distance between two points in canvas

by

You can do it with pythagoras theorem

If you have two points (x1, y1) and (x2, y2)
then you can calculate the difference in x and difference in y, lets call them a and b.

enter image description here

var a = x1 - x2;
var b = y1 - y2;

var c = Math.sqrt( a*a + b*b );

// c is the distance
