Returns the vertical y-component of the vector

lengthdir_y(len, dir)

Returns: double

This function returns the y-component of the given vector. Imagine a circle around your starting position and then imagine a point anywhere on that circle. This point is in a distance len from starting position and in a direction dir. This function will return the relative positon of a y coordinate from your starting position.

This function, when used with lengthdir_x, gets the position of that point on the circle to be used in code by the instance.

lengthdir_y(5,50); //return -3,830222

This function returns -3,830222, so the y coordinate of that point in a distance 5 and in the dircetion 50, is y - 3,830222.
