Since 1.12, (at least) the entityPlayerMP.theItem...blah blah... Something or other.... Seems to have been removed to test the players gamemode. So how can I do this in 1.12? Trying to make a cobweb-like object, but with a lesser effect. Also needs to not slow down players in creative. The slow down works fine though.

I am sorry, but I can't seem to find anything on EntityPlayer::capabilities at all. Nothing is showing up if I hit ctrl+space and if I manually type it out, it says "The target type of this expression must be a functional interface". Would you care to enlighten me on what and how to use the two colons, and why capabilities is not showing up?

No, you just use a dot in place of the :: or #, like this: player.capabilities.isFlying.

 

It's just that when talking about methods and fields, it's useful to be able to distinguish at a glance whether we're talking about something static where you actually call it on the class (like EntityPlayer.staticVariable), or about something which must be called on an instance (like player.capabilities).

 

Because an instance of something is (usually) stored in a variable, and a variable could have any name, it's potentially ambiguous to invent a variable name without specifying what class the object is an instance of. I could say "you need to use variable.capabilities", and you might rightly ask "but what is variable?". Or I could say "you need to use EntityPlayer.capabilities", and then you might come back and say "my IDE tells me I can't access a non-static field statically", because you'd get errors if you typed in exactly that. So the alternative to these two possibly-confusing approaches is to use the class name (which makes it clear what kind of object we're using) and use a hash or double-colon in place of the dot (which represents the fact that it should be called on an instance of the class).

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
