Hello, i want to make a animation, but i need to know if a entity is attacked by another entity. How to achieve this?

Have you looked at how vanilla animals (e.g. pig or sheep) do it?

 

Mob entities (which include animals) have goals, which are registered and run by the entity's GoalSelector object.  Every mob entity has a goal selector, which is public, and the goal selector has a getRunningGoals() method to get all of the currently-active goals.  Take a look at e.g. PigEntity and find the obviously-named goal which controls panic behaviour. That should be all the info you need.

 

It might actually be simpler just to check that the animal has a non-null getRevengeTarget()... depends on how much control you want over the process.  An animal can have a revenge target but not have a running panic goal if it can't find somewhere to flee to, for example.

@desht, wow, thanks a lot! I simply cant see the Vanilla code, but thank for your help!

If you can't view vanilla code from your IDE, get that fixed ASAP. It's absolutely critical to be able to see how vanilla and Forge code does stuff, not to mention being able to set debugging breakpoints.

So, with the school i not have much time, but i tried to do what i can. I searched a lot about streams and optional, and this is what i actually have:

 

https://github.com/DragonGamerDevelopers/NewFantasyMod/blob/1.15.2/src/main/java/mod/dragonita/fantasymod/entities/UnicornEntity.java#L45

 

Now it say me that the optional was empty, i really not know why, as my entity walk, look me, if i attack it it flee (The panic), etc…. So i need help. I have done all what i have can do in the Java basic side, but i think that this was a problem more related to modding as Java basic. I have see the Vanilla of getRunningGoals, so normally it should work, so why it don‘t work?

Pls, i really need help!

return entity.goalSelector.getRunningGoals().anyMatch(prioritizedGoal -> prioritizedGoal.getGoal().getClass() == TargetGoal);

@loordgek, thanks for replying! I not am a expert in Java, but it always return false. It not should be the case. I am trying to make a animation if the entity was attacked and the Panic Goal was activated, i kill all my entity (i not have add a regular spawn) and attack the entity, but the Logger always say me that it was false, but i attacked the entity, so it can‘t be was false (as it run in a random position, so it was false), so i not understand why it was always false.

getRunningGoals is empty, i dnot know why

 

@loordgek It can‘t be possible, so i not understand.

I think it's a Mojang problem, or am I using it wrong? Because otherwise it's impossible to get a goal, and the function «getRunningGoals()» is also useless

@desht, my entity extends Agreableentity, like a pig, and i don‘t think that a passive entity has a revengetarget.

it is server side probably, you need to send a packet

i dont know for sure

 

edit: did a test and it is server side only

Edited March 16, 20205 yr by loordgek

@loordgek, so i need to use @OnlyIn(Dist.SERVER)? So thanks, i will try!

What is a packet? Ok, now i am lost.

Edited March 17, 20205 yr by DragonITA

Is this a PacketBuffer.

How do you know this?

Not sure if this is 100% correct, but unless something is graphics, sound, or input, I would pretty much guess that it's server-side, otherwise the client could corrupt/hack stuff.

@Ugdhar, i should send a PacketBuffer, but i have a many questions: why and how.

Unfortunately, not something I've messed with yet, so I can't help you. I was just explaining how (I'm guessing) the other person was figuring it was server side..

Ok thanks, but now where can i find a tutorial about PacketBuffer: @Ugdhar, @Cadiboo, @desht or @loordgek???

https://mcforge.readthedocs.io/en/1.13.x/networking/simpleimpl/

@loordgek 1.13 is outdated, and i have see this site, but it not helped me out.

that is the current way how to do it

and stop ping everybody it is annoying
