OR and AND Gates

They are logic gates used in MCreator, scratch, any type of programming and maths.

OR means that one of the two "things" (well, I'm not English so I don't know how to call them) should be true, but it works if both of them are true too.

AND means that both of the "things" should be true

Examples:

If (has item in player inventory = tnt) OR (has item in player inventory = fire_charge)

do explode

This way when the player has a tnt, a fire charge or both of them in his inventory, he explodes.

If ( is thundering) AND (has player item in inventory = fire_charge)

Strike lightning

Remove 1 item from player inventory (fire_charge)

This way, if the weather is lightning and you have a fire charge in the inventory, the fire charge will be removed and you will strike a lightning

If the weather is not lightning or if you don't have fire charge in your inventory you won't do any lighting

I hope it helped

(Sorry for bad English)

Nice
