some planned screen anvancement and let functions of screen support crafter.

[17183248569]

i want to try my best to do that....... maybe i will need others help in the future....

• get_current_screen()
• event of player opening GUI

that pr is to add a scarpet usage like this:

/script run __on_player_open_screen(player, screen_type)->get_current_screen(player [, a lambda callback could be here] )

to make script can touch vanilla screens. (after getting the screen object, users can use it.)
because the user may want to append a callback to the returned screen, i let the 2nd argument of __on_player_open_screen be screen_type instead of a screenvalue itself.

=================================

it supports crafters now.
use create_screen(player(),'crafter_3x3', 'screen name') to create one.
which has following property:
crafter_slot_disable_0
crafter_slot_disable_1
...
crafter_slot_disable_8 (the slots "lock")

crafter_enable (the red arrow in the middle of the GUI) (should it be called red_arrow directly?)

===================================

example 1:
/execute as @p run script run create_screen(p,'crafter_3x3','333',_(s,p,x,y)->(if(!s,return());screen_property(s,'crafter_slot_disable_0',screen_property(s,'crafter_slot_disable_8'))))

===============
example 2:

/script run __on_player_open_screen(p,s)->get_current_screen(p,_(s,p,x,y)->(if(!s,return());screen_property(s,'crafter_slot_disable_0',screen_property(s,'crafter_slot_disable_8'))))

the script creates an callback function to be run on player opens a vanilla screen. and in which, another callback is added to that vanilla screen.

I would not use a map, since you aren't gonna know whether a screen will ever be retrieved from get_current_screen at all. It just creates additional overhead, that would be required even if no scripts are running. Setting it to null and returning a null value when querying name is probably the best option IMO.

ok. i let it be null now.
