#===============================================================================​
# Mouse System (RGSS3 - VX Ace)
# By Jet10985(Jet)
# Tłumaczył: GmenGul
# Some Code by: Woratana, Berka
# Uses: ListRA-92's Path Finding
# Super Heavy Testing/Debug Help/Requested By: Nathanial(Beleren)
#===============================================================================​
# Skrypt ten pozwoli ci w pełni korzystać z myszy w grze stworzonej w RMVX Ace
# dla różnych Celów.
# Ten skrypt zawiera: 7 dostosowywań opcji.
#===============================================================================​
# Overwritten Methods:
# Game_Player: move_by_input
#-------------------------------------------------------------------------------
# Aliased methods:
# Scene_Map: update, terminate, update_transfer_player
# Input: update, trigger?, press?, repeat?, dir4, dir8
# Window_Selectable: update, top_row=
# Scene_File: update
# Window_NameInput: update
# Game_Temp: initialize
# Game_Event: initialize, update
#===============================================================================​
#Tego poniżej nie tłumaczę, bo myślę że to nie potrzebne :)

=begin
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
--------------------------------------------------------------------------------
Don't stop the player when walking over a touch event:

By default, this script will stop a mouse-caused movement if the player walks
over/under a player touch/event touch event. If you want the event to activate,
but for the player to keep walking to their destination, put this comment in the
event:

MOUSE NOSTOP
--------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------
Dodatkowe Uwagi:

Z wyboru okna np. przedmioty, które mają więcej rzeczy niż to, co pokazano,
gracze mogą:
-albo umieścić kursor pod oknem, aby przewinąć w dół ,lub
-użyć kółka od myszy, bądź (tego co jest między LPM a PPM)
do przewijania w górę / w dół.

Możesz włączyć zdarzenia przyciskiem akcji przez stojące obok zdarzenie i
kliknięcie na nie myszką.
