Map System (General Feature Information)

[Toxocious]

Description

Ideally we'll implement a map system similar to the map engine that the Gen 3 Pokémon games (Emerald, Ruby, and Sapphire).

Dependencies

• Phaser (https://phaser.io/)
  • Javascript based rendering engine for games

Features

• Render Tiled files as maps
  • Phaser has innate support for this if exporting the map as a .json file
• Support for a variety of entities/objects
  • NPCs
    • Custom overworld sprite
    • Custom dialogue
    • Movement property
  • Player Entity
    • Sets player spawn position for the map
  • Warp Tiles
    • Sets destination for the map it leads to
  • Encounter Tiles
    • Tile integer denotes encounter zone to draw encounters from
  • Layer Transition Tiles
    • Needed to handle transitioning to other map layers
      • Ex. ground layer to mountain layer (over-simplified)
• Animate player movement
  • Walking
  • Surfing
  • Fishing
• NPCs can move
• NPCs have custom dialogue
• Move from map to map
• Surfing on water
• Sliding on ice
• Procedural map generation
  • Useful for PMD-like dungeons
• Map Exp/Level
  • Earnable via catching/fighting/releasing wild encounters
  • Encounter odds of wild encounters influences earned Map Exp
  • Map Level increases odds of finding Shiny Pokémon
• Itermfinder
  • Ping for 'hidden' overworld items
  • Manual Mode
    • High-range
      • 8-tile radius around the player
  • Automatic Mode
    • Low-range
      • 4-tile radius around the player
• Overworld Bosses
  • n% chance to spawn per frame
  • Can be fought a single time per spawn
  • Can not spawn if an overworld boss is already active

Technical Requirements

• Render Tiled .tmx files via Phaser
• Parse and set collision tiles
• Handle player interaction w/ NPC objects
• Parse and set encounter tiles
• Program surfing logic
  • Check for water tiles
  • Check for current player movement method
    • Walking
    • Surfing
    • Sliding
    • Warping
• Program sliding on ice logic
  • GridEngine has innate support for this
    • https://annoraaq.github.io/grid-engine/examples/ice-movement.html
• Allow custom keybinds
  • Store/Update these in the database
  • Movement Keybinds
    • Left
    • Right
    • Up
    • Down
  • Interaction Keybinds
    • Interact
    • Fishing
    • Use Key Item

Map Creation README

A README will need created as a guide on how to create maps, and will cover layer naming, object layer naming, supported objects, and tilesets.
