Self switches help

[wlzza]

Hi there just wondering how I could incorporate arrays to self switches. I'm noob at scripting.

for k in 1...5
if $game_self_switches[[2, $game_map.events[k], 'A']] == true
  do this
else
  do that
end
end

What have I done wrong?

I don't understand what you're trying to do. Can you please be more precise?

 

[wlzza]

Sorry. I have lots of events on the map and what I'm trying to do is that I need a way to check if these events have self switch A on or off. Having that many events I assume using arrays would be the best way. The problem is, I'm having difficulties in getting it to work.

The syntax to check Self Switches is $game_self_switches[map_id, event_id, switch]

map_id is the id of the map in which your event is
event_id is the id of the event you want to test
switch is "A","B","C" or "D"

In your case

for i in 1...5
  if $game_self_switches[2, k, 'A']
    your code 1
  else
    your code 2
  end
end

I've tried that but got errors. Not just the i and the k.

I even tried:

for k in 1...5
  if $game_self_switches[[2, k, 'A']] == true
    code 1
  else
    code 2
  end
end

 

[Dargor]

use $game_self_switches[2, k, 'A']

not $game_self_switches[[2, k, 'A']]

I know, that's the problem single or double square brackets it doesn't work. In VX if you use $game_self_switches[2, k, 'A'] i get this error "wrong number of arguments (3 for 1)". While if I use $game_self_switches[[2, k, 'A']] it doesn't do anything.

When I use a fixed variable such as $game_self_switches[[2, 2, 'A']] it works but defeats my purpose.

I appreciate your help Dargor.

 

[Dargor]

Oh, I'm sorry, you were right, it requires an array. I worked with self_switches only once a while ago.
I did it that way:
key = [map_id, event_id, switch]
if $game_self_switches[key]
...

and I have tested your method:
for i in 1..5
  p $game_self_switches[[1,i,'A']]
end
And it works fine. It prints 5 false.

One VERY easy thing to overlook....

$game_map.needs_refresh = true

So, when its "Doing nothing", yes the switch most likely had changed in the event yet the event's graphic/behavoir doesn't change without that line. At least thats how it works in XP, VX might be different but I think its the same in this case.

 

[Dargor]

I think it works the same in VX. Correct me if I'm wrong, but, your goal was to test if a self-switch is on/off, right?
If you wanted to turn a self-switch on/off, then you will need to do as Kain told and add

$game_map.needs_refresh = true

After you change your self-swith.
