Migration guide for level builders

TR1X

Version 4.9 to 4.10

  1. Update fog configuration
    If you wish to force your fog settings on player:

    • Rename draw_distance_fade to fog_start
    • Rename draw_distance_max to fog_end

    If you wish to give the player agency to change the fog:

    • Remove draw_distance_fade and draw_distance_max

Version 4.7 to 4.8

  1. Rename basic keys

    • Replace file key with path for every level.
    • Replace music key with music_track for every level.

  2. Update level enumeration structure:

    • The "type": "title" property is no longer supported. Instead, the title level needs to be placed in the top-level "title" key.
    • The "type": "cutscene" property is no longer supported. Instead, the cutscenes need to be placed in the top-level "cutscenes" array.
    • All FMVs need to be placed in its own top-level "fmvs" array.

  3. Update individual level sequences

    • start_game should be removed.
    • exit_to_cine should be removed.
    • exit_to_level should be replaced with level_complete. No parameter needed.
    • display_picture no longer takes a picture_path argument and instead just takes a path.
    • loading_screen no longer takes a picture_path argument and instead just takes a path.
    • level_stats no longer takes a level_id argument.
    • total_stats no longer takes a picture_path argument and instead takes a background_path.
    • play_fmv no longer takes a fmv_path argument and instead takes a fmv_id.
    • play_synced_audio is renamed to play_music and takes a music_track argument rather than audio_id.

  4. Update strings
    The game strings are now placed in a separate file, TR1X_strings.json5 in preparation to eventually support internationalization. Elements such as item titles or item names need to be configured entirely in the new file, so all "strings" keys can be safely removed from the game flow. Refer to game strings documentation for more details.

TR2X

Version 1.2 to 1.3

  1. Rename objects

    • Replace "detonator_1" with "gong".
    • Replace "detonator_2" with "detonator_box".

  2. Re-add pistols
    Pistols are no longer added automatically to a level that follows one in which Lara previously lost her weapons. A game flow entry to re-add pistols will be required - refer to the Diving Area level in the default game flow.

  3. Bears, wolves and ice warriors
    If you wish to use the bear, wolf or ice warrior (monk with no shadow) from The Golden Mask while still being able to use big spiders, small spiders and other monks, use the following object slots.

    • Bear: slot 265
    • Wolf: slot 266
    • Ice warrior: slot 267

  4. Disabling gym The option gym_enabled is no longer available. If you need to remove the access to Lara's Home, please either remove the relevant level from the game flow (this may break existing saves), or change its type to "dummy" to get it ignored (this will work with existing saves).

Version 1.0.2 to 1.1

  1. Update first level inventory allocation
    The first level no longer hard-codes the shotgun, flare and small/large medi pack allocations. To continue to have Lara start with these items, refer to the shipped game flow file's Great Wall sequences, specifically the give_item entries.
