If you’re looking to make your Sims completely invincible and free from basic needs in The Sims 4, there are a number of cheats and mods that can help. Whether you’re storytelling, experimenting, or just want to skip the micromanagement, this guide covers everything you need.

Step 1: Enable Cheats

Before using any of these commands, you need to enable cheats in the game.

1. Press Ctrl + Shift + C (or Command + Shift + C on Mac) to open the cheat console.
2. Type: testingcheats true
3. Press Enter.

Once cheats are enabled, you’re ready to proceed.

How to Make Sims Invulnerable

Disable Death Completely

To turn off death for all Sims in the game, type: death.toggle false.
To turn death back on later, use: death.toggle true.

Add Traits That Prevent Death

You can assign traits to Sims that block certain types of death.

To make a Sim immune to fire, use: traits.equip_trait BurningMan.
If you have the Realm of Magic pack, you can make a Sim immortal by typing: traits.equip_trait Trait_Magic_Marketability.

These traits make your Sims more resilient to specific in-game hazards.

Use Mods for Full Invincibility

For more advanced control, especially if you want Sims to be immune to all possible death triggers (including debug interactions), consider installing these mods:

• MC Command Center (MCCC) – Offers control over death, aging, autonomy, and more.
• UI Cheats Extension – Allows you to right-click to change needs, moodlets, traits, and more directly in the user interface.

These tools provide more flexibility than base game cheats.

How to Max Out or Freeze Needs

Max Out All Needs Instantly

To instantly fill every need for a Sim, type: sims.fill_all_commodities.

To target a specific need, use the command fillmotive motive_ followed by the need you want to fill. For example:

• Hunger: fillmotive motive_hunger
• Energy: fillmotive motive_energy
• Bladder: fillmotive motive_bladder
• Hygiene: fillmotive motive_hygiene
• Social: fillmotive motive_social
• Fun: fillmotive motive_fun

Freeze Needs Using Shift-Click

If you want your Sims’ needs to stop decaying over time, hold Shift, click on your Sim, and choose Cheat Need > Disable Need Decay.

To return needs to normal, select Cheat Need > Enable Need Decay.

Make Needs Static for All Sims

To disable needs or autonomy across your entire household, use the command: households.autonomy_mode no_autonomy.

This will keep all Sims in a passive state without requiring your intervention.

By using these cheats and tools, you can make your Sims truly invincible and free from basic needs. This is ideal for creative storytelling, long-term saves, or simply enjoying the game without interruptions.
