testfor a cocoa bean in a player inventory [duplicate]

Question

I have been trying to figure this one for about an hour now, yet I still can find out how to detect cocoa beans in a player inventory in 1.11.2. The command I used was:

/testfor awesomeianman {Inventory:[{id:"minecraft:dye",Damage:3}]}

Whenever I tried this, it didn't have an output! Could someone please help me, and tell me if the command is completely wrong?

Answer 1

When testing for pre-existing data, you must specify that data as it's saved. The Damage tag is saved as a short, so you append the numerical value with an "s":

/testfor awesomeianman {Inventory:[{id:"minecraft:dye",Damage:3s}]}
