Remember Event Position

​

​

Introduction

If you move an event on the map, then leave the map and return, the event, by default, goes back to its original place (where you put it when designing the map).  To get around that, you have to have another parallel process event run every time the map loads, to see if the event has been moved, and if so, put it in its correct position.  If you have a lot of these in your game, that's a lot of additional events just checking where events should be.  I dislike lots of "setup" events sitting around on maps, so devised this little script to let you tell an event to save its position, and go back to that position next time the map is loaded.

How to Use

Paste this script into its own slot in the Materials section.

Script

7. # Description: This script lets you set the position and direction
8. #              where an event will appear next time the map is
9. #              loaded.  Events will appear in this new position
10. #              rather than the place they were put during design.
11. #
12. #--------------------------------------------------

14. # Installation:
15. #
16. # Copy into a new script slot in the Materials section
17. #
18. #--------------------------------------------------
19. #
20. # Use:
21. #
22. # Examples below show syntax for an Event Command on an Event Tab.
23. #   You can use @event_id for the current event, or specify an event number.
24. # To execute from within a Set Move Route command, omit the
25. #   $game_map.events[@event_id]. part, and just use save_pos() and forget_pos().
26. #
27. # To tell an event to move to its current position the next time
28. # the map is loaded, execute the following in a script call:
29. #   $game_map.events[@event_id].save_pos()
30. #
31. # To tell an event to move to a particular position (not its
32. # current position) the next time the map is loaded,
33. # execute the following in a script call:
34. #   $game_map.events[@event_id].save_pos(1, 2, 8)
35. # - the above will move the event to x=1, y=2, facing up
36. #
37. # To tell an event to forget its previously remembered position
38. # and go back to its default position the next time time map
39. # is loaded, execute the following in a script call:
40. #   $game_map.events[@event_id].forget_pos()
41. #--------------------------------------------------
43. class Game_System

52. end
54. # Check to ensure $game_system.event_positions exists (save files created
55. # prior to this script being added would not have it initialized)

75.     if $game_system.event_positions.has_key?([map_id, @id])
76.       mvx, mvy, mvdir = $game_system.event_positions[[map_id, @id]]
77.       moveto(mvx, mvy)
78.       set_direction(mvdir) if mvdir
79.       @stop_count = 0
80.       refresh
81.     end
82.   end
84.   def save_pos(x = @x, y = @y, dir = @direction)
85.     $game_system.event_positions[[@map_id, @id]] = [x, y, dir]
86.   end
88.   def forget_pos
89.     $game_system.event_positions.delete([@map_id, @id])
90.   end

How to Call

SpoilerTo save the current event's position after a move route:



                Code:       

1. Set Move Route: This event (Wait)
2.               : $>Move away from Player
3.               : $>Script: save_pos()

复制代码

To save the current event's position, but not within a move route:

(Conditional branch only used as part of the example - only the last line is relevant)



                Code:       

1. Conditional Branch: Switch [0001: Move Away] == ON
2.   Set Move Route: This event (Wait)
3.                 : $>Move away from Player
4. Else
5.   Set Move Route: This event (Wait)
6.                 : $>Move toward Player
7. Branch End
8. Script: $game_map.events[@event_id].save_pos()

复制代码

To make a different event move to a set position when the map is next loaded:



                Code:       

1. Script: $game_map.events[4].save_pos(15, 6)
