Mappet

Mappet is a toolset for building Minecraft adventure maps, with features that can also support scripted roleplay and machinima. Its in-game dashboard lets map makers manage NPCs, quests and quest chains, dialogues, events, crafting tables, region blocks, and factions. NPCs can serve as traders, conversational characters, quest givers, companions, enemies, or bosses, and their appearances can be customized with morphs. Node-based dialogues can branch and trigger actions according to a player's state, while quests and quest chains organize objectives, rewards, and story progression. Node-based events let creators build logic that affects the world, players, or NPCs without writing code, and JavaScript or Kotlin scripts provide another way to program custom game logic. Trigger blocks respond to player interaction, while region blocks can react to players entering or leaving an area; these can start conversations or events, complete quests, activate scenes, or control access. Conditions, expressions, and stored global, player, or NPC states let creators make behavior depend on game context and track story progression. Virtual crafting tables let players exchange specified ingredients for outputs, supporting systems such as making gear from items dropped by mobs. Creators can display custom HUD scenes for information such as mana, energy, or scores, and use temporary world morphs for visual effects or animations. The mod also supports custom graphical interfaces through its scripting API and lets map makers load custom sound files for use in their worlds.
