Lose Ammo = Notification Sent

How do i make it so if a player loses shards on a weapon, a notification sends them to refill their shards?

Bonus Question

How do i also make it so when a player is at 12 light or medium shards, they’re reminded to refill their shards or else they’ll reach 0 ammo?

Do you mean when it hits 0, or everytime it goes down?

When it hits 0.

The player uses energy to move.

Have a constant checker that checks said item. You can do this with wire repeaters. It checks if you have 0 of said item, and if it passes, you get sent the notification?

I’ll try that later - breakfast time.
