The survival system you wish you had yesterday

You start building a survival game.
You “just need health, hunger, and thirst.”

A few hours later:

• timers everywhere

• UI polling every frame

• systems fighting each other

• edge cases when the player dies

And you haven’t even started the actual game.

SurvivalNeeds fixes that.

Drop it in. Press Play. It works.

Add the component. Assign a config. Hit Play.

You immediately get:

• Health with regeneration and fall damage

• Hunger with starvation damage

• Thirst with dehydration damage

• Events for everything

No setup. No digging. No guessing.

One config. Full control.

Every number lives in one place:

• Drain rates

• Damage timing

• Thresholds

• Regen behaviour

Duplicate configs for difficulty levels or characters.
Swap them at runtime. No code changes.

No Tick. No polling. Just events.

Everything is event-driven:

• OnHealthChanged → update UI instantly

• OnLowHungerEntered → trigger warnings

• OnDeath → fire gameplay logic

No wasted performance. No constant checks.
