Create a screen to track relative positions
/*global screen:true*/
var screen = require("screen")
, point = require("screen/point")
, center = point({ x: 10, y: 10 })
, one = point({ x: 12, y: 12 })
, two = point({ x: 8, y: 8 })
var world = screen(center, 20, 20)
, relativeOne = world.add(one)
, relativeTwo = world.add(two)
relativeOne(function (point) {
console.log("one x", point.x, "y", point.y)
// one x 12 y 12
// one x 7 y 7
// one x 10 y 10
})
relativeTwo(function (point) {
console.log("two x", point.x, "y", point.y)
// two x 8 y 8
// two x 3 y 3
})
// move to 15, 15
center({ x: 15, y: 15 })
// move one to 15, 15
one({ x: 15, y: 15 })npm install screen
