RMDC #1: Dynamically Ordered Choice Selections

I’m not exactly sure how this would be achieved (I’m not a coder), but here’s some pseudocode/flow of events.
First we need a few things.

mapsVisited = 0
mapsOrder[]
mapsName[]


For RM’s sake (and my incompetency), let’s say these three are actually $game_variables[10], $game_variables[11], $game_variables[12] respectively.

Create an autorun event on each map that is teleport-enabled, that only runs once.
Have the autorun call a common event (for convenience) that writes the map’s ID and name, to the mapsOrder and mapsName array, like so:

$game_variables[11][$game_variables[10]] = $game_map.map_id
$game_variables[12][$game_variables[10]] = $game_map.name


This records the map’s id and name that you just visited, and stores it into their Arrays.

$game_variables[11][0] is the ID of the first map you visited,
$game_variables[11][1] is the second, etc.


Then, have the event increments mapsVisited by 1.

$game_variables[10] = $game_variables[10] + 1


Make sure the autorun turns on a self-switch to disable it from running again.
This makes it so it “saves” the map order, letting you write the next map into the second/third slot and so on.

Now, on your teleporter NPC script call:
This is a script call to create choices. It’s recommended against, so probably scripting a Command Window would be much more efficient.

i = 0
max = $game_variables[10]
params = []
choices = []
while i < max do
choices.push($game_map.$game_variables[12][i].to_s)
i += 1
end
choices.push("Cancel")
params.push(choices)
params.push(max+1)
setup_choices(params)


This sets up the choices. The loop generates choices pulling them out of the array until the max is reached. Remember, $game_variables[12] is the mapsName array. The cancel command is placed after all the warp choices are created.

This next part I’m not entirely sure on, and may need to be scripted.
I know the choice command returns 0/1/2/3/whatever depending on which choice is selected. Let’s say this variable is called warp_choice_id. When the choice is executed:

$game_player.reserve_transfer($game_variable[11][warp_choice_id], 50, 50, 2)


This script call will move the player to the set map_id, at 50, 50, facing downwards. In this way, the first choice would return 0, which is the first map we’ve visited. 1 is the second. So on. The coordinates to be warped to can be also stored in another array, assuming all portals aren’t at 50, 50 on their respective map.

I hope this somewhat makes sense, it’s not a full solution, however.
