# FAQ

## What does AreaRegen do?

AreaRegen restores selected areas after blocks are damaged or changed.

## Does it only work with TNT?

No. Explosion regeneration is one feature, but areas can also regenerate from mining, block placing, fire, and supported entity block changes.

## Can I use it for prison mines?

Yes. Create an area and add the `MINING` trigger.

## Can I make TNT arenas regenerate?

Yes. Create an area and add the `EXPLOSION` trigger.

## How do I prevent item duplication with chests?

Use container mode `EMPTY`. This restores the container block but clears the inventory.

## Should I use RESTORE mode for containers?

Only in controlled areas. `RESTORE` can duplicate items if players can take items before regeneration happens.

## Does AreaRegen support WorldGuard?

WorldGuard support is planned. Custom AreaRegen areas are currently available and will remain supported.

## Why are blocks not regenerating?

Check:

- the block is inside the area
- the correct trigger is enabled
- the material is not blacklisted
- the whitelist is not blocking the material
- the area is enabled
- the delay has passed

## What is a tick?

Minecraft runs at about 20 ticks per second. A delay of 40 ticks is about 2 seconds.
