Point

If a function receives a point as an argument it could be several things:

1. You can specify two parameters x, y directly as arguments of the function. E.g. selection:contains(8, 20)
2. You can specify an object with x and y properties. E.g. selection:contains{ x=8, y=20 }
3. You can specify an array with two elements: E.g. selection:contains{ 8, 20 }
4. You can specify a Point instance: E.g. selection:contains(Point(8, 20))

Point()

Point()
Point(otherPoint)
Point(x, y)
Point{x=number, y=number}
Point{number, number}

Creates a new Point instance with the given coordinates (or x=y=0 if they are not specified).

Point.x

local x = point.x
point.x = newX

Point.y

local y = point.y
point.y = newY
