# Mouse System
# By Jet10985(Jet)
# Some code by Daniel Martin
#===============================================================================
# This script will allow full use of the mouse inside of Ace for various
# purposes.
# This script has: 13 customization options.
#===============================================================================
# Overwritten Methods:
# Game_Player: move_by_input
# Window_NameInput: item_max
#-------------------------------------------------------------------------------
# Aliased methods:
# Scene_Title: start
# Scene_Map: update, terminate, update_transfer_player
# Input: update, trigger?, press?, repeat?, dir8/dir4
# Window_Selectable: update
# Scene_File: update, top_index=
# Game_Event: update, setup_page
# Game_Player: check_action_event, get_on_off_vehicle
# Game_System: initialize, on_after_load

Showing text above event when mouse hovers:

If you want a message to appear over an event's head if the mouse is hovering
over the event, put this comment in the event:

MOUSE TEXT MESSAGE HERE

everything after TEXT will be the hovering display.
--------------------------------------------------------------------------------
Change mouse picture above event when mouse hovers:

If you want the mouse's picture to temporarily change whne over an event, put
this comment in the event

MOUSE PIC NAME/NUMBER

if you put a name, the mouse will become that picture, but if you put a number
then the mouse will become the icon that is the id number
--------------------------------------------------------------------------------
Specific mouse click movement routes:

If you want the player to land specifically in a square around an event when
they click to move on the event, put one of these comments in the event:

MOUSE MOVE UP/LEFT/RIGHT/DOWN

only put the direction that you want the player to land on.
--------------------------------------------------------------------------------
Click to activate:

If you want an event to automatically start when it is clicked on, place
this in an event comment:

MOUSE CLICK
--------------------------------------------------------------------------------
Ignore Events:

To have an event be ignored when the mouse makes it's movement path(as if the
event isn't there), put this comment in the event:

MOUSE THROUGH
--------------------------------------------------------------------------------
You can do some extra things with the mouse using event "Script..." commands:

Mouse.set_pos(x, y) will set the mouse's position to the x and y specified.

Mouse.area?(x, y, width, height) will check if the mouse is inside the given
rectangle, on-screen. This does not account for a scrolled map.

Mouse.grid will return where on the screen the mouse is, not accounting for
a scrolled map. Returns an array: [x, y]

Mouse.true_grid will return where on the map the mouse is, accounting for a
scrolled map. Returns an array: [x, y]

Mouse.click?(1 or 2) will return true/false depending on if a mouse button was
clicked, in only the current frame. Use 1 for left-click, 2 for right-click.

Mouse.press?(1 or 2) will return true/false depending on if a mouse button is
currently being pressed. Use 1 for left-click, 2 for right-click.

swap_mouse_cursor(data) will change the idle look of the mouse icon, and it will
persist on the savefile. data is either the name of a picture eg "cursor-icon2"
or the number of an icon eg 12. Images should be in quotes, whereas icons should
just be the number.
--------------------------------------------------------------------------------
Extra Notes:

You can activate action button events by standing next to the event and clicking
on it with the mouse.
