Genre: Survival

Resource scarcity, needs management, and progression through crafting define survival games.

Available Scripts

inventory_slot_resource.gd

Expert inventory slot pattern using Resources for save compatibility.

Core Loop

Harvest

Gather resources (Wood, Stone, Food)

Craft

Convert resources into tools/items

Build

Construct shelter/base

Survive

Manage needs (Hunger, Thirst, Environmental threats)

Thrive

Automation and tech to transcend early struggles NEVER Do in Survival Games NEVER make gathering tedious without scaling — 50 clicks for 1 wood = fun-killer. Tool tiers MUST multiply yield: Stone Axe = 3 wood, Steel = 10 wood. Respect player time. NEVER use instant death for starvation — 0% hunger → instant death = cheap. Use gradual HP drain (2 HP/sec). Player should see death coming and scramble for food. NEVER allow infinite inventory stacking — 999 stacks of everything removes resource management strategy. Use weight systems OR stack limits (64 per slot). NEVER make crafting recipes a guessing game — Trial-and-error crafting = 1990s design. Show discovered recipes. Discovery can exist, but once learned, must be persistent. NEVER let needs decay at constant rate regardless of activity — Hunger drains same speed while sleeping/running? Unrealistic. Sprint = 3x drain, idle = 0.5x drain. NEVER spawn enemies near player's bed/spawn point — Dying, respawning into 3 enemies = rage quit. Enforce safe zone radius (50m) around respawn. Phase Skills Purpose 1. Data resources , custom-resources Item data (weight, stack size), Recipes 2. UI grid-containers , drag-and-drop Inventory management, crafting menu 3. World tilemaps , noise-generation Procedural terrain, resource spawning 4. Logic state-machines , signals Player stats (Needs), Interaction system 5. Save file-system , json-serialization Saving world state, inventory, player stats Architecture Overview 1. Item Data (Resource-based) Everything in the inventory is an Item.

item_data.gd

extends Resource class_name ItemData @ export var id : String @ export var name : String @ export var icon : Texture2D @ export var max_stack : int = 64 @ export var weight : float = 1.0 @ export var consumables : Dictionary

{ "hunger": 10, "health": 5 }

1. Inventory System A grid-based data structure.

inventory.gd

extends Node signal inventory_updated var slots : Array [ ItemSlot ] = [ ]

Array of Resources or Dictionaries

@ export var size : int = 20 func add_item ( item : ItemData , amount : int ) -> int :

1. Check for existing stacks

2. Add to empty slots

3. Return amount remaining (that couldn't fit)

pass 3. Interaction System A universal way to harvest, pickup, or open things.

interactable.gd

extends Area2D class_name Interactable @ export var prompt : String = "Interact" func interact ( player : Player ) -> void : _on_interact ( player ) func _on_interact ( player : Player ) -> void : pass

Godot-Specific Tips

TileMaps

Use

TileMap

(Godot 3) or

TileMapLayer

(Godot 4) for the world.

FastNoiseLite

Built-in noise generator for procedural terrain (trees, rocks, biomes).

ResourceSaver

Save the

Inventory

resource directly to disk if it's set up correctly with

export

vars.

Y-Sort

Essential for top-down 2D games so player sorts behind/in-front of trees correctly.

Common Pitfalls

Tedium

Harvesting takes too long.

Fix

Scale resource gathering with tool tier (Stone Axe = 1 wood, Steel Axe = 5 wood).

Inventory Clutter

Too many unique items that don't stack.

Fix

Be generous with stack sizes and storage options.

No Goals

Player survives but gets bored.

Fix

Add a tech tree or a "boss" to work towards. Reference Master Skill: godot-master
