[VX] Overworld Character Animation Stop Script Location?

[Untitled]

The italicized part has been solved~
So my code's about the most simple edit to the stock scripts:

  #--------------------------------------------------------------------------
  # * Processing of Movement via input from the Directional Buttons
  #--------------------------------------------------------------------------
  def move_by_input
    return unless movable?
    return if $game_map.interpreter.running?
    case Input.dir8
    when 1;  move_lower_left  #new
    when 3;  move_lower_right #new
    when 5;  move_upper_right #new
    when 7;  move_upper_left  #new
    when 2;  move_down
    when 4;  move_left
    when 6;  move_right
    when 8;  move_up
    end
  end

Basically, it's adding four more directions of overworld movement that are already programmed for, and it works great--for three of the four. When trying to move_upper_right, the character just stops and doesn't move anywhere.

The character also stops when trying to move diagonally along a straight wall, but that at least is expected.

The bolded part has not yet been solved
And while I'm asking such a small question, where's the script that causes the player character (or any overworld character, I guess) to stop animating when they stop moving? I've found some suspects, but nothing definitive.

Thanks!

Ever wondered why down is represented as 2 or up as 8? Look at the NumPad on your keyboard.

In short, change the 5 to a 9.

Can't help with the second problem since I don't use VX.

OHHHH okay that makes a lot of sense, thanks! I didn't think of that since I'm on a laptop.

I suppose since the main issue is solved, I'll go ahead and change the topic title, thanks again!
