Gosu: Making image point to cursor
I'm using Gosu on Ruby 1.9.3 MRI
I have a Player class, with it's own x/y variables, aswell as a Cursor class with the same.
Considering the Player and Cursor class don't differ in movement and values are the same, how can I calculate the angle to #draw_rot the player in?
Above: screencap of the game window.
The cursor is an image centered on the actual OS cursor, by the way.
Solution
The angle between the two objects is:
angle = Gosu.angle(player.x, player.y, cursor.x, cursor.y)
which is what you can use as the angle when drawing the player with Image::draw_rot
