Hey I'm typing out some old AUM workshops to improve my skills. I was just wondering if anybody can explain to me how the following two lines of code work:



I understand what it does (it moves a little ship up, down, left, and right) but I don't understand why the player_speed.x is controlled by mouse_force.y. I thought it would be mouse_force.x.

If anybody has the time to answer this dumbass question, that would be really awesome.

mouse_force.y != 0 is true when you move the mouse up and down (push/ pull it from/ to you).
mouse_force.x != 0 is true when you move the mouse left or right.

The code seems to move the player upwards with player_speed.x, so you need to control the latter variable with the y-coordinate of the mouse speed vector.
