Survival Crafting

生存制作游戏设计手册

A playbook for survival-crafting games — the gather → craft → build loop, survival needs, the crafting/tech progression, and base building. This is a compositional skill: it orchestrates inventory data, world content, persistence, and threats. It does not re-teach those primitives; it defines the loop and the pressure systems (needs, scarcity, escalation) that make survival tense rather than tedious.

这是一份生存制作类游戏的设计手册——涵盖收集→制作→建造的核心循环、生存需求、制作/科技进阶以及基地建造内容。这是一项组合式技能：它统筹物品栏数据、世界内容、存档机制以及威胁系统。本手册不会重新讲解这些基础概念，而是定义让生存体验充满紧张感而非乏味感的循环机制与压力系统（需求、资源稀缺性、难度升级）。

When to use

适用场景

Use when the player gathers resources, crafts items/structures, manages survival needs, and builds a base against escalating threats: survival sandbox, crafting/base-building game.
Use when designing needs (hunger/thirst/temperature), a crafting tech tree, gathering loops, or base placement/building.

When not to use: crafting as a minor RPG feature →

rpg

. Permadeath grid dungeon →

roguelike

. For inventory/items as data assets, use

godot-resources

unity-scriptableobjects

; for world generation,

procedural-gen

当玩家需要收集资源、制作物品/建筑、管理生存需求并建造基地以应对不断升级的威胁时使用：适用于生存沙盒、制作/基地建造类游戏。
当设计生存需求（饥饿/口渴/温度）、制作科技树、收集循环或基地选址/建造系统时使用。

**不适用于以下场景：**制作仅作为RPG次要功能时→使用

rpg

技能。永久死亡类网格地牢游戏→使用

roguelike

技能。若将物品栏/物品作为数据资产处理，请使用

godot-resources

unity-scriptableobjects

；若涉及世界生成，请使用

procedural-gen

技能。

Core loop

核心循环

Gather raw resources → craft tools/items → build and upgrade a base → manage survival needs → explore farther for better resources → survive escalating threats → repeat at a higher tier. Each loop should unlock the next loop (better tools → reach new biomes → new resources → better crafts). When that ladder breaks, the game becomes a grind.

**收集原始资源→制作工具/物品→建造并升级基地→管理生存需求→前往更远区域探索获取更优质资源→应对不断升级的威胁→进入更高阶段循环。**每个循环都应解锁下一个循环（更高级工具→抵达新生物群系→获取新资源→制作更高级物品）。一旦这个进阶阶梯断裂，游戏就会沦为乏味的刷资源行为。

Must-have systems

必备系统

Resource nodes + gathering — harvestable world objects; tool requirements/tiers; respawn.
Inventory — stacks, capacity (slots or weight), drop/transfer, hotbar.
Crafting — recipes (inputs → output), a crafting station/tech gate, a tech tree.
Survival needs — hunger, thirst, temperature, stamina, health, with decay + consequences.
Base building — placeable structures, a build grid/snapping, storage, crafting stations.
World + day/night — biomes/resources (often procedural); a time cycle driving threats.
Threats — hostile creatures/weather/events that escalate; combat or avoidance.
Save/load — world state, inventory, base, needs, progression; large-world persistence.

资源节点与收集系统 — 可采集的世界对象；工具需求/等级；资源重生机制。
物品栏系统 — 物品堆叠、容量限制（格子数或重量）、丢弃/转移功能、快捷栏。
制作系统 — 配方（输入→输出）、制作台/科技解锁门槛、科技树。
生存需求系统 — 饥饿、口渴、温度、耐力、生命值，包含数值衰减机制与对应后果。
基地建造系统 — 可放置的建筑、建造网格/对齐功能、存储设施、制作台。
世界与昼夜循环系统 — 生物群系/资源分布（通常为 procedural 生成）；驱动威胁的时间循环。
威胁系统 — 不断升级的敌对生物/天气/事件；战斗或躲避机制。
存档/读档系统 — 世界状态、物品栏、基地、生存需求、进度的保存；大型世界的持久化存储。

Design knobs

设计调节项

Knob	Effect	Notes
Needs decay rates	pressure cadence	Slow enough to explore, fast enough to matter.
Need-failure consequence	stakes	Damage over time, not instant death.
Resource scarcity / respawn	exploration push	Scarce near base → travel for more.
Tool tiers / gating	progression ladder	Better tool → new node types.
Recipe complexity / tech depth	long-term goals	Multi-step chains, not flat lists.
Inventory limit (slots/weight)	logistics tension	Forces base trips and storage.
Threat escalation curve	difficulty over time	Night/seasonal/event ramps.
Day length	rhythm	Day = gather, night = defend.

调节项	效果	说明
需求衰减速率	压力节奏	慢到足够玩家探索，快到让需求产生实际影响。
需求未满足的后果	风险程度	造成持续伤害，而非直接死亡。
资源稀缺性/重生机制	探索驱动力	基地附近资源稀缺→促使玩家外出寻找更多资源。
工具等级/解锁门槛	进阶阶梯	更高级工具→可采集新类型资源节点。
配方复杂度/科技深度	长期目标	多步骤制作链，而非扁平化列表。
物品栏限制（格子数/重量）	后勤压力	迫使玩家返回基地存放物品。
威胁升级曲线	随时间变化的难度	夜晚/季节/事件驱动的难度提升。
昼夜长度	游戏节奏	白天=收集资源，夜晚=防御基地。

Patterns

设计模式

1. Needs decay with graded consequences

1. 生存需求逐步衰减并带有分级后果

python

undefined

python

undefined

Pseudocode in the per-frame/per-tick update. dt = seconds. Needs fall; failure bleeds HP.

def update_needs(p, dt): p.hunger = max(0, p.hunger - HUNGER_RATE * dt) p.thirst = max(0, p.thirst - THIRST_RATE * dt) p.temp = approach(p.temp, ambient_temperature(p), TEMP_RATE * dt)

# Consequences are graded, not binary: warnings, then attrition — never instant death.
if p.hunger == 0 or p.thirst == 0:
    p.hp -= STARVE_DAMAGE * dt          # damage over time creates urgency with recovery room
if p.temp < COLD_THRESHOLD or p.temp > HEAT_THRESHOLD:
    p.hp -= EXPOSURE_DAMAGE * dt
if p.hunger > 0 and p.thirst > 0 and not exposed(p):
    p.hp = min(p.max_hp, p.hp + REGEN_RATE * dt)   # safe + fed => heal

undefined

def update_needs(p, dt): p.hunger = max(0, p.hunger - HUNGER_RATE * dt) p.thirst = max(0, p.thirst - THIRST_RATE * dt) p.temp = approach(p.temp, ambient_temperature(p), TEMP_RATE * dt)

# Consequences are graded, not binary: warnings, then attrition — never instant death.
if p.hunger == 0 or p.thirst == 0:
    p.hp -= STARVE_DAMAGE * dt          # damage over time creates urgency with recovery room
if p.temp < COLD_THRESHOLD or p.temp > HEAT_THRESHOLD:
    p.hp -= EXPOSURE_DAMAGE * dt
if p.hunger > 0 and p.thirst > 0 and not exposed(p):
    p.hp = min(p.max_hp, p.hp + REGEN_RATE * dt)   # safe + fed => heal

2. Crafting: validate, then atomically consume inputs

2. 制作系统：先验证条件，再原子性消耗材料

python

python

undefined

Pseudocode. Recipes are data: inputs -> output, with an optional station/tech requirement.

recipe = {"id": "stone_axe", "inputs": {"wood": 3, "stone": 2}, "output": ("stone_axe", 1), "station": "workbench", "requires_tech": "basic_tools"}

def can_craft(recipe, inv, tech, station): if recipe.get("requires_tech") and recipe["requires_tech"] not in tech: return False if recipe.get("station") and recipe["station"] != station: return False return all(inv.count(item) >= n for item, n in recipe["inputs"].items())

def craft(recipe, inv, tech, station): if not can_craft(recipe, inv, tech, station): return False for item, n in recipe["inputs"].items(): inv.remove(item, n) # consume all, then add inv.add(*recipe["output"]) # atomic: no partial craft return True

undefined

recipe = {"id": "stone_axe", "inputs": {"wood": 3, "stone": 2}, "output": ("stone_axe", 1), "station": "workbench", "requires_tech": "basic_tools"}

undefined

3. Gathering gated by tool tier

3. 资源收集受工具等级限制

python

undefined

python

undefined

Pseudocode. A node yields only if the held tool meets its required tier.

def harvest(node, tool): if tool.tier < node.required_tier: return notify("Need a better tool") # e.g. stone node needs a pickaxe, not fists node.hp -= tool.power if node.hp <= 0: spawn_drops(node.drop_table) # weighted drops (see roguelike loot pattern) node.start_respawn(node.respawn_time) # node returns later; world isn't depleted forever

Pitfalls / failure modes

常见陷阱/失败模式

Needs that kill instantly → frustration and save-scumming. Make failure damage over time, with clear warnings and a recovery path (Pattern 1).
Grind without a ladder → gathering that never unlocks new gathering. Each tier must open the next (better tool → new node → new resource → better craft).
Non-atomic crafting → inputs consumed but output not granted on an edge case. Validate first, then consume-and-add as one step (Pattern 2).
Inventory with no limits → no logistics tension and no reason for a base/storage. Cap by slots or weight.
Permanently depleting the world → players strip the map and quit. Respawn nodes or regenerate resources over time.
Per-frame decay unscaled by
dt
→ needs drain at different speeds on different hardware. Scale by
```
dt
```
.
No save / fragile save of a large world → a crash wipes hours. Persist world+base+needs incrementally; version it (see
```
save-systems
```
).
Flat threat curve → no late-game pressure. Escalate via night/season/event tiers.

生存需求直接导致死亡→引发玩家挫败感与反复读档行为。应让需求未满足时造成持续伤害，并提供明确警告与恢复途径（参考模式1）。
无进阶阶梯的刷资源行为→收集资源却无法解锁新的收集能力。每个等级必须能开启下一个等级（更高级工具→新资源节点→新资源→更高级制作物）。
非原子性制作→极端情况下消耗了材料却未获得成品。先验证条件，再执行消耗材料并添加成品的原子性操作（参考模式2）。
无限制的物品栏→无后勤压力，玩家无需建造基地/存储设施。需通过格子数或重量限制物品栏容量。
世界资源永久耗尽→玩家搜刮完地图后就会退出游戏。应设置资源节点重生或资源随时间再生机制。
未按
dt
缩放的帧级需求衰减→不同硬件上需求消耗速度不同。需按
```
dt
```
缩放衰减速率。
无存档机制/大型世界存档不稳定→崩溃会导致数小时游戏进度丢失。需增量持久化存储世界+基地+需求数据，并进行版本控制（参考
```
save-systems
```
技能）。
扁平化的威胁曲线→后期游戏无压力。需通过夜晚/季节/事件等级提升难度。
