How to Verify the Addon and Base Mod Are Active

Damagesource is Not Null Mod is an addon rather than a standalone mod, meaning it requires DSNNULL Basic to function. Checking that both mods are loaded properly ensures the runtime safety layer is active before you enter a heavily modded world.

Checking Required Mods

1. Open your Minecraft mods folder before launching the game and confirm that DSNNULL Basic is present alongside Damagesource is Not Null Mod.

2. Launch Minecraft to the title screen. If the game warns you about a missing dependency, close the game and add DSNNULL Basic to your mods folder.

3. Click the Mods button on the title screen and scroll or type in the search bar to verify DamageSource Is Not Null appears in your active mods list.

Confirming In-Game Protection

1. Load into a single-player world and confirm combat works normally against standard mobs like Zombies or Creepers as well as third-party modded creatures.

2. You do not need to press any keybind or equip any item to turn the shield on; the addon runs automatically in the background as a runtime safety layer.

3. To double-check that the addon's command system is responding, open chat with cheats enabled and type /dsnnull debug testall.

Once verified in the Mods menu and in-game chat, the addon will silently replace null DamageSource errors with safe damage information whenever third-party mods misfire.
