Custom level creation/meta.txt

Help expand it

This page descibes the early access verion 0.1346 save_breaker. It may not be completely correct for the the current stable version, nor the latest unstable version. Help us update it, and you get a cookie.

meta.txt is a text file that lists a number of fields that describe the level, each field should start on a new line. While most of these are optional you should set at least:

• kind
• size
• title
• dialogue

Fields

• kind: LevelKind
  • One of misc, combinational, sequential, architecture, factory
• immutable_program: Bool
  • Player cannot edit the program in assembley enabled RAM & ROM
• immutable_spec: Bool
  • Player cannot edit the spec.isa
• overwrite_assembly: Bool
• no_score: Bool
• tests: SInt
  • Number of tests to run, defaults to 1
  • Will stop after first time check_output() returns fail.
• title: String
  • Pretty name for display in game
• default_isa_spec: String
• default_assembly: String
• no_panel: Bool
• no_state_ui: Bool
• no_controls: Bool
• size: (S16,S16,S16,S16)
  • Coordinates of the edges of the allowed draw area (left, top, right, bottom)
  • Ignored for architecture levels
• unlocks_components: [ComponentKind]
• components_available: {ComponentKind: SInt}
  • This overrides the default component list based on the level progression
  • Maximum number of allowed instances of ComponentKind
  • -1 means unlimited
  • If this option is specified then custom components will NOT be available unless the IO pins (com_cc_input: -1, com_cc_output: -1) are also listed.
• add_components: {ComponentKind: SInt}
  • This adds to the default component list based on the level progression
  • -1 means unlimited
• remove_components: [ComponentKind]
  • Exclude these Components from the build menu
• tick_past_fail: SInt
  • Run this number of ticks, even after detecting a failure.
  • check_output() must return win on the last tick or the level cannot be completed. An early return win ignores this and can cause the level to succeed before then.
• output_history_pins: SInt
  • Legacy, DO NOT USE for new levels.
  • For older levels that do not use ui.txt configures the display of IO pins on the bottom panel.
• copy_solution_to_level: [String]
  • Note: Potentially broken parsing code, might copy stuff to weird locations on small mistakes
• copy_solution_to_architecture: String
• save_solution_as_custom: String
• unlocks_info: String
• input_labels: [(String,)|(String,String)|(String,String,String)]
  • Same Note, but less danger, just messed up names
• output_labels: [String]
  • Same Note
• unlocks_pages: [String]
  • Same Note
• unlocks_special: [String]
  • Same Note
• background: UInt
• arch_input_word_size: SInt
• next_level: String
• dialogue: Dialogue
• post_mortem_first_win: Dialogue
• post_mortem: Dialogue

Dialogue

The <Dialogue> format is TODO.

Hints

To disable all custom components specify components_available with all of the allowed built-in components, excluding the IO pins.
