Class prefix: v

• Required parameters:
  • key,
  • loc_txt or localization entry (reference)
• Optional parameters (defaults):
  • atlas = 'Voucher', pos = { x = 0, y = 0 } (reference)
  • config = {}, unlocked = true, discovered = false, no_collection, prefix_config, dependencies, display_size, pixel_size (reference)
  • pools: List of keys to ObjectTypes this center should be injected into
    • Expects a list of keys like this:

     	{
     		["Foo"] = true,
     		["Bar"] = true,
     	}

  • cost = 10,
  • requires: specify a list of one or more vouchers by their full key (e.g. 'v_grabber' for vanilla vouchers, or 'v_pref_myvoucher' for a modded voucher from the mod with prefix 'pref')

• calculate(self, card, context) (reference)
• loc_vars, locked_loc_vars, generate_ui (reference)
• redeem(self, card)
  • Defines the behavior of a Voucher when redeemed.
• set_ability(self, card, initial, delay_sprites)
  • Set up initial ability values or manipulate sprites in an advanced way.
• add_to_deck(self, card, from_debuff)
  • Modify the game state when this card is obtained.
  • Cards are considered added when they become undebuffed (in this case, from_debuff will be true).
• remove_from_deck(self, card, from_debuff)
  • Modify the game state when this card is sold, destroyed, or otherwise removed.
  • Cards are considered removed when debuffed (in this case, from_debuff will be true).
• in_pool(self, args) -> bool, { allow_duplicates = bool }
  • Define custom logic for when a card is allowed to spawn. A card can spawn if in_pool returns true and all other checks are met.
  • allow_duplicates allows this card to spawn when one already exists, even without Showman.
  • When called from generate_card_ui, the _append key is passed as args.source.
• update(self, card, dt)
  • For actions that happen every frame.
• set_sprites(self, card, front)
  • For advanced sprite manipulation that happens when a card is created or loaded.
• load(self, card, card_table, other_card)
  • For modifications to sprites or the card itself when a run is reloaded.
• check_for_unlock(self, args) -> bool
  • Configure unlock conditions. Refer to the function check_for_unlock in Balatro's code for more information.
• set_badges(self, card, badges)
  • Add additional badges, leaving existing badges intact. This function doesn't return; add badges by appending to badges.
  • Avoid overwriting existing elements. It will cause text to appear on the top left corner of your screen instead.
  • Function for creating badges: create_badge(_string, _badge_col, _text_col, scaling)
    • _string: Text displayed on the badge.
    • _badge_col = G.C.GREEN: Background colour.
    • _text_col = G.C.WHITE: Text colour.
    • _scaling = 1: Relative size of the badge.
  • Example:

   {
   	set_badges = function(self, card, badges)
   		badges[#badges+1] = create_badge(localize('k_your_string'), G.C.RED, G.C.BLACK, 1.2 )
   	end,
   }

• set_card_type_badge(self, card, badges)
  • Same as set_badges, but bypasses creation of the card type / rarity badge, allowing you to replace it with a custom one.
• draw(self, card, layer)
  • Draws the sprite and shader of the card.
