Help using NBT blocks

You can not alter existing NBT tags yet without custom code. In 1.9.1, you will be able to using command procedure block.

I believe there are commands that allow this, check Minecraft Wiki would be my recommendation.

Hey klemen, I created the following procedure:

On Block Right Clicked:

Set Local: (string)Command to Create text with "/effect "

                                               Create text with Get Display name of provided entity

                                                                                                                                                                    " minecraft:health_boost 10 5 true"

Execute command / Get Local: Command at x,y,z

I did it both with "/effect " and "effect ". Upon adding send to chat of all players Get Local: Command, it appeared that the command was exactly right, but yet it didn't go off.

Typing in exactly that string as it was printed in chat manually however did play the command. Am I missing something?

Try using entity selector @p

Thanks, that worked! I'll make a quick video tutorial on it because i predict this will be asked about multiple times from here on.

Cool, thanks!
