Main ideas / concepts taught

  • Build a Stardew Valley–style 2D game in Godot (GDScript + Godot 4 features) by recreating core gameplay loops:

    • Player movement + animations
    • Tool system (axe, hoe, watering can, sword, fishing rod, seeds/planting)
    • Tile-based world (grass/soil/water layers, terrain auto-tiling)
    • Tool-driven world changes
      • Hoe creates soil tiles
      • Watering adds water patches
      • Seeds spawn plants on farmable soil
      • Fishing checks whether the target tile is water
      • Axe/Sword affect world objects (trees/enemies)
    • Day/night cycle
    • Plant growth + harvesting + UI/diagnostics

  • Emphasize “advanced Godot” workflows:

    • AnimationTree for scalable animation logic
    • Autotiling/terrain sets for procedural-looking tile placement
    • Resources as data containers (especially for plants)
    • Signals for decoupled communication (player ↔ level ↔ objects)
    • Performance monitoring via Godot’s hardware monitor/debug monitors
    • Tools (run code in editor) for quick scene preview/randomization

Methodologies / step-by-step systems (organized)

1) Project setup & input architecture (foundational)

  • Define project-wide settings:
    • Pixel art: default texture filter = Nearest
    • 2D collision layers (terrain, player, objects, characters)
    • Window size (example: 1920×1080)
  • Input Map includes actions such as:
    • Movement: left/right/up/down
    • Tool use: action (tool use)
    • Tool cycling: tool forwards / tool backwards
    • Build actions / diagnose (debug UI)

Lesson: Create enums + input actions early so later systems don’t depend on fragile strings.

2) Player movement & direction capture

  • In player.gd:
    • Store a global variable: var direction: Vector2
    • In a movement function:
      • direction = Input.get_vector(left, right, up, down) (axis order matters)
    • Use:
      • CharacterBody2D velocity = direction * speed
      • move_and_slide() in _physics_process
  • Add a Camera2D zoom to make the tiny player visible during dev.

Lesson: Keep direction logic centralized so animations, offsets, and tools can reuse it.

3) AnimationTree-driven animation logic (movement + tools)

Key idea: Instead of manually selecting hundreds of animations in code, use:

  • Blend spaces (directional selection via coordinates)
  • State machine (idle vs walk, one-shots for tools)
  • Possibly blend tree/root connections

3A) Movement: idle + walk via BlendSpace2D

  • Create a move state machine containing:
    • walk state as a BlendSpace2D
    • idle state as a separate BlendSpace2D
  • Add discrete animations at points in the blend space:
    • Idle down/left/right/up and walk down/left/right/up
    • Include diagonals by adding extra points, otherwise animations “fall apart”
  • In script (animate()):
    • When moving:
      • Compute a rounded direction so blend coordinates match exactly
      • Update blend position parameters for both idle and walk (so direction is retained when stopping)
    • When not moving:
      • Transition to idle state

3B) Tools: one-shot animations returning to movement

  • In AnimationTree:
    • Connect movement output to a root output
    • Add a tool state machine with tool animations
  • Use a OneShot node:
    • Tool animations play once
    • Then return to movement state
  • Fire the OneShot from code:
    • Set AnimationTree parameter for tool_one_shot.request = FIRE

Lesson: AnimationTree becomes the “logic engine” for animation transitions; code stays small.

4) Tool system via enums + cycling

4A) Define enums

  • Enums include a tool enum for:
    • X, hoe, watering can, sword, fishing rod, seeds
  • Use enums to avoid typo-prone strings.

4B) Cycling tools with forward/backward inputs

  • Maintain:
    • var current_tool: ToolEnum
  • On input:
    • Use direction = input_value from forward/back actions (e.g., Q/E gives -1/+1)
    • Update with wrapping:
      • current_tool = posmod(current_tool + int(direction), tool_enum_size)
  • Also support modulo behavior so values never go out of dictionary range.

Lesson: Enums + wrapping create reliable deterministic tool selection.

4C) Prevent movement while tool animation plays

  • Add can_move: bool = true
  • In _physics_process:
    • Only apply movement if can_move
  • In AnimationTree:
    • Connect animation started → can_move = false
    • Connect animation finished → can_move = true

5) Level creation with TileMap layers + Terrain autotiling

5A) Use TileMapLayers (not deprecated TileMap)

  • Create separate layers:
    • grass layer
    • soil layer
    • water layer (includes animated tiles)
  • For each layer:
    • Create TileSet
    • Create atlas texture (except the animated water case)
    • Configure terrain sets:
      • Mode: match corners/sides or match corners and sides
      • Define terrain type and tiles
      • Connect rules so Godot auto-selects correct neighbor tiles

5B) Add water animation

  • For water.png tile set:
    • Enable animation frames/columns (e.g., 4 frames)
    • Speed tuned by frame duration
  • Place only the leftmost tile; Godot handles the frame sequence.

5C) Collisions for terrain tiles

  • Create physics layer definitions in TileSet:
    • Enable collision tiles on grass border/land
  • Enable debug display for visible collision shapes and adjust coastline shapes.

6) Tool-to-world interaction using signals (decoupling)

6A) Player emits tool usage

  • From player animation events (frame-accurate):
    • Emit signal:
      • tool_use(tool_enum, position: Vector2)
  • In _player:
    • Fire it at the correct animation frame (timing fix)

6B) Level listens and applies effects

  • In level.gd:
    • Connect player tool_use to level logic
    • Convert pixel position → grid coordinate:
      • grid = Vector2i(int(pos.x / tile_size), int(pos.y / tile_size))
    • Use match(tool) to apply per-tool behavior.

7) Hoe/Watering/Seeds mechanics (tile + object spawning)

7A) Hoe: create soil terrain

  • On hoe:
    • Ensure the tile is farmable (custom data layer farmable_bill on grass)
    • Also ensure the target cell is valid (avoid null custom data)
  • Convert grid coordinate and place terrain:
    • Use set_cells_terrain_connect on soil layer

7B) Watering can: add water patches only on soil

  • On watering:
    • Check if there is soil on that tile:
      • Use get_cell_tile_data() to confirm presence
    • If soil exists:
      • Place a water patch in soil_water layer
      • Choose among atlas coordinates randomly (one of 3 patches)

7C) Fishing rod: water check

  • On fishing:
    • Determine if target tile is NOT water:
      • Compare against grass used cells or check water layer usage
    • If tile isn’t in water:
      • print “not fishing”
    • If tile is water:
      • print “fishing”
  • Includes fixes:
    • Collision shape adjustments and negative-grid offset bug correction (debug layer used to visualize targeting)

7D) Seeds: spawn plant objects on soil + avoid duplicates

  • On seed placement:
    • If soil exists AND no plant already exists in that grid cell:
      • Spawn plant scene
  • Maintain:
    • used_cells: Array[Vector2i]
  • Only allow one plant per grid coordinate.

8) Plant growth system using Resources (data-driven)

8A) Resource architecture

  • Create a PlantResource (extends Resource) containing:
    • texture (or atlas texture/plant textures)
    • grow_speed
    • h_frames (max growth stages)
    • def_max (days to decay without watering)
    • (later) name + icon texture for UI
  • Create instances dynamically based on database entries.

8B) Plant scene as “shell”

  • plant.tscn:
    • StaticBody2D + sprite (or flash sprite)
    • Collision shape
    • Stores:
      • grid coordinate
      • reference to plant_resource
      • age/health derived from resource values
  • Methods:
    • setup(grid_coord, parent, plant_resource)
    • grow(watered: bool, sprite)
      • if watered: age increases using grow speed
      • else: decay counter increases; remove plant at threshold

8C) Day reset / watering clearing

  • On day reset:
    • Clear water tiles (soil water layer)
    • Iterate plants in group plants
      • If watered that day: grow
      • If not watered: decay/remove when needed

8D) Collecting plants when complete

  • Plant has an Area2D circle:
    • Detects player overlap
  • When complete:
    • flash effect
    • remove plant after flash via a callback in flash sprite

8E) Resource changed signal for UI/cleanup

  • In resource:
    • emit changed (or specifically when death occurs)
  • In plant info UI:
    • connect to resource changes to update UI and hide when dead

9) Dynamic plant resource creation from a database

  • data.gd contains:
    • plant data dictionary keyed by seed enum
    • values include:
      • texture paths
      • icon texture
      • grow speed
      • h_frames
      • def_max
  • On planting seeds:
    • create PlantResource.new()
    • call plant_resource.setup(seed_enum, data)
    • pass resource into plant scene

Debugged lesson: Incorrect resource data types (float grow speed being coerced to int → rounding down to 0) can break growth logic; ensure floats are stored correctly (e.g., 1.0 not 1 depending on resource variable type constraints).

10) Day/night cycle (lighting + restart transition shader)

10A) Daytime color via CanvasModulate

  • Use:
    • CanvasModulate node
  • In level.gd:
    • Export gradient daytime_color
    • A timer defines day length
    • Sample gradient using normalized time:
      • daytime_point = 1 - (time_left / day_length)
    • Set modulate color accordingly

10B) Day transition overlay shader

  • Create a CanvasLayer overlay with a shader (circle wipe)
  • Animate shader uniform progress using tween from 1→0 (and back)
  • Trigger restart with input action day_change (temporary)
  • On restart:
    • reset day timer
    • call level reset for content refresh:
      • apples respawn for living trees
      • plants update later based on watering rules

11) Environment props with “Tools” for editor-time preview/randomization

  • Create a simple object scene marked as a Tool:
    • runs in editor (and at runtime)
  • Randomize:
    • sprite frame selection for bushes/rocks
    • exported parameters (size, style enum)
    • optional randomize boolean
  • Add editor UI button via export tool button:
    • call a callable function to randomize instantly in editor

12) UI: tool selection and plant info overlay

12A) Tool UI scaling + auto-hide

  • Create tool UI scene with:
    • container holding tool textures (created dynamically from enum)
  • On tool change:
    • show container for 1 second via Timer
    • highlight currently selected tool by tweening size up/down

12B) Seat UI (parallel system)

  • Extend UI for seats:
    • similar enum mapping
    • separate container but shared logic for reveal/highlight
  • Ensure tools and seats never display simultaneously.

12C) Plant info panel

  • Create:
    • plant info scene: icon, name label, growth bar, death bar
    • plant info container: scrollable list at top-left
  • When planting:
    • instantiate a plant info panel for that plant
    • set label/icon from plant resource
    • update progress bars via plant resource values
  • Toggle display via diagnose input (N key)
  • Hide plant info when plant decays/is collected.

13) World combat: trees and (basic) enemies

13A) Tool-based hit detection

  • On tool use:
    • iterate objects in group objects
    • if distance < threshold:
      • call hit(tool) on that object

13B) Tree behavior

  • tree static body with:
    • flash sprite using a shader-driven flash
    • apples spawn points
    • apples are random-position sprites
    • health; on death replace with stump + update collision shape
  • On hit:
    • if tool is axe:
      • flash + remove one apple
      • reduce health
    • always reduce health when appropriate tool logic is applied
  • Day reset:
    • trees reset health to allow infinite harvesting cycle until cut down

13C) Enemy blob (basic exercise-driven system)

  • Moves towards player
  • Flash when hit by sword
  • Push away with tween
  • Explosion animation on defeat

Enemy full gameplay beyond movement/flash/explode is indicated as coming later.

14) Performance monitoring methodology (hardware monitor)

  • Use Godot monitors:
    • FPS is the main metric (target ≥ 30)
    • Watch CPU/GPU processing times
    • Watch RAM/VRAM usage
    • Watch object counts and video memory
  • “Bad practice” example:
    • creating new sprites every frame → FPS drops + memory rises (leak-like behavior)

Lesson: Monitor continuously; fix bottlenecks early.
