Why I can't hit in the air in MInecraft or why I can't hit other people but mine blocks?

If I want to beat other people in the PVP it is not possible, but I can remove blocks. Is that because I installed Labymod?

In the air?

It may be due to the mods you have installed, but PVP on servers is always possible if the host has not turned it off.

I actually only play on GommeHD

I have no idea who or what that is.

And because of the question in the air, no on the ground in Gm2

Because FriendlyFire is activated and PvP deactivated, I would guess.

And do you play MCPE, or why is it in the tags?

For about 7 years the largest German Minecraft server. Bruh.

You don't have to know.

Well then, as I said, PVP is deactivated… Ask other players.

Yes, you have to - at least if you answer questions about Minecraft, or if you play the game from time to time. Otherwise you come across like a noob.

No. I just don't play on well-known servers and that's why I haven't been a noob for a long time.

So I had that on Java and PE, with both. The funny thing is in single player it's over too.
