I know that I also try that but for big Problems like that I often start with Vanilla code that works quite similar like in this case the FishingRod and FishHook similar to my Clawshot and its head to get the theory.

BTW: How would I add a signature to my posts?

I feel pretty dumb to ask but how get I an Entity by its UUID as world only has the method getPlayerEntitiesByUUID()

You'll have to loop through the loadedEntityList and look for it yourself. Since there is no method available already.

Still the Entity respawns after being setDead. What am I missing?

What happens in the if statement if the compound doesn't have a UUID saved to it. Hint: The entity will be null.

clawshot_head.setDead();

What does this do? It references a new Entity just created in this method, not yet spawned in the world, and sets it to be dead.

What it should do is gets the entity from the nbt and set that entity to be dead.

Ok, I should give more details about that:

The Entity is spawned correctly. Check.

It lives a certain time. Check. (Not exactly what I want it to do but I should already know how to fix that)

Then it dies (NOT by Right clicking again). Check

And Respawns at its original spawnPos and moves again.

But you're right about the error in the code,will fix that.

In your update method you only set it dead on the client.

    }

I give the command to kill it on both sides,am I right? So why it doesn't works?

Also setting the motion to o doesn't works. Is this also a problem with sides.

Yes.

And then it does a few things with if it's in the ground and then sets itself to be dead, but only if the above is true. Which setDead are you having a problem with exactly?

I changed the code to mainly use the UUID of the Player after thinking over Problematic code #9

Didn't solved the Problem though

My Projects:

Cruelars Triforcemod (1.12 release; 1.14 alpha soon coming)

 

Important:

As my mod is on at least 10 different third party sites without my permission, I want to warn you about that with a link to StopModReposts

I found something that might give a hint to the core of the problem:

I'm calling shoot in the constructor and in the readSpawnData()

If I remove it in the constructor the Entity can't move.

If I remove it in readSpawnData() the behavior doesn't change

I noticed it by reading the output of shoot() when I Right click to shoot:

A minor thing would be that I want to have a chain or at least a line between the entity and the item and don't know how to do that.

So I just managed to set up the breakpoints. Seems like I've done something wrong before.

But still The Entity is only set dead when I reload the world. All other conditions than entityplayer==null seem to be false all the time.

I'll appreciate any help. (Code is in my older posts)

Also the Entity starts after a short time at its startposition with its new movement speed.

How can my Entity "die" without causing one of my Breakpoints? The only Output I get is on Loading a World cause off EntityPlayer being null

Override set dead, return super & set a breakpoint there

[11:13:43] [main/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:209]: EntityPlayerSP['Player636'/283, l='MpServer', x=250.85, y=72.79, z=261.42]
[11:15:01] [main/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:onUpdate:92]: ln:92 got called

It dies from me being to far away. Remaining Problems:

I can't retract it and can't use the Item more than one time.

I would like to have a line drawn between the Entity and me. Quite similar to the fishing hook.
