[Resolved] Cannot convert nil into string

[MDC123]

I'm really no good at scripting, and this error is really starting to annoy me.

I am using a script which gives custom Battle Backgrounds and at first it worked fine, then the next time i tried it i get the error

Script 'Cache' line 75: TypeError occured.

cannot convert nil into String

Any way of fixing this?

Post your scripts.

What it is doing is trying to load from the cache, but something is sending a nil argument. My best guess it's sending an instance of an object, but the instance is undefined and sending nil instead.

Seems like you have to modify this part with your map-battleback associations:

  # Picture (Only required if BB_TYPE = 2)
  M_B_BACK = {
    # Map ID => "Picture File Name(Graphics/System)"
    1 => "Mountains"
  }

1. Put your battle backdrop files in the Graphics/System/ folder.
2. For each map, add a key => value pair to that part of the script I highlighted. For example, if map with ID 1 uses a background file called Mountains.png, map 2 uses a background file called Forest.png, and 3 uses Grasslands.png, you'd have something like:

  # Picture (Only required if BB_TYPE = 2)
  M_B_BACK = {
    # Map ID => "Picture File Name(Graphics/System)"
    1 => "Mountains"
    2 => "Forest"
    3 => "Grasslands"
#... and so on
  }

Right now it probably looks for battle backdrop for a certain map (say number 3) and can't find any associated backdrop because you didn't define it; so it gives you an error.

Ok, tried that, but now i get

Script 'Battleback' line 24: SyntaxError occured.

as soon as i start the game  :crazy:

Line 24 would be   2 => "Forest" in the example, but in my case it is 2 => "Goblin"

Sorry to be such a pain  :sad:

Make sure you have:

  M_B_BACK = {
    # Map ID => "Picture File Name(Graphics/System)"
    1 => "Mountains",
    2 => "Goblin"
  }

Not

  M_B_BACK = {
    # Map ID => "Picture File Name(Graphics/System)"
    1 => "Mountains"
    2 => "Goblin"
  }

Oh, sorry, add commas between each pair... like this:

  # Picture (Only required if BB_TYPE = 2)
  M_B_BACK = {
    # Map ID => "Picture File Name(Graphics/System)"
    1 => "Mountains",
    2 => "Forest",
    3 => "Grasslands"
#... and so on
  }

Edit: SephirothSpawn beat me to it.
