Update of bug #14550 (project wesnoth):
Status: None => Wont Fix
_______________________________________________________
Follow-up Comment #2:
1.13 supports a new tag [sync_variable] that can manually sync the position
and makes it possible to implement common usecases of needs_select= with
[sync_variable] instead of needs_select= :
For example instead of
[event]
name=start
[set_menu_item]
id=move_unit
description= _ "Move!"
image=buttons/WML-custom.png
needs_select=yes
[command]
{MOVE_UNIT x,y=$moving_unit_x,$moving_unit_y $x1 $y1}
{VARIABLE moving_unit_x $x1}
{VARIABLE moving_unit_y $y1}
[/command]
[/set_menu_item]
[/event]
[event]
name=select
first_time_only=no
{VARIABLE moving_unit_x $unit.x}
{VARIABLE moving_unit_y $unit.y}
[/event]
you can now write:
[event]
name=start
[set_menu_item]
id=move_unit
description= _ "Move!"
image=buttons/WML-custom.png
[command]
[sync_variable]
name=moving_unit_x,moving_unit_y
[sync_variable]
{MOVE_UNIT x,y=$moving_unit_x,$moving_unit_y $x1 $y1}
{VARIABLE moving_unit_x $x1}
{VARIABLE moving_unit_y $y1}
[/command]
[/set_menu_item]
[/event]
[event]
name=select
first_time_only=no
{VARIABLE moving_unit_x $unit.x}
{VARIABLE moving_unit_y $unit.y}
[/event]
To become independent from the location it is now also possible to idently the
selected unit by id and write instead:
[event]
name=start
[set_menu_item]
id=move_unit
description= _ "Move!"
image=buttons/WML-custom.png
[command]
[sync_variable]
name=moving_unit_id
[sync_variable]
{MOVE_UNIT id=$moving_unit_id $x1 $y1}
[/command]
[/set_menu_item]
[/event]
[event]
name=select
first_time_only=no
{VARIABLE moving_unit_id $unit.id}
[/event]
