[1.12] Custom Entity lagging while moving every once in a while

[AleMax]

Hello,

I've got a problem.

I made a completely custom Entity, and got it to move smoothly,

unfortunatly every few seconds it laggs (it ports ~1 block back and immediatly returns).

When i accelerate (changing the speed every tick) the Entity, it will even lag more often and when i ride it then as well, it probably laggs two or tree times a second.

I also noticed that the player riding the entity wont get ported back, the player just continues normally, so my guess is that this is only a render issue on the client side and probably desync is a issue.

Someone knows what the problem could be?

No one would know without your code.

Jup i thought that but seriously, its probably the most basic it can get i guess.

Well, thats the onUpdate()-Method of the entity:

	 public void onUpdate() {
	    this.prevPosX = this.posX;
	    this.prevPosY = this.posY;
	    this.prevPosZ = this.posZ;
	    super.onUpdate();
	    speed = 0.1;
	    this.motionZ = speed;
        
	    this.move(MoverType.SELF, this.motionX, this.motionY, this.motionZ);
    }

It doesnt really do anything special.
I actually did overwrite the move function, but it does exactly the same thing in the end, and it cant really be becaus of this, i already tried with the original move function and the same lag happened.

If the problem probably isn somewhere else the rest of my code is here but it is a real mess right now because i added a bunch of things which i didnt finished yet. (The entity i made should be EntityTrain)

Try calling super.onupdate()

Apparently I'm blind sorry.

So well i did some debugging and if i did nothing wrong it just looks like that everything in the onUpdate()-Method gets set properly (like the position variables and stuff), but then the game deicides just randomly every few seconds that in the next onUpdate() call all those changes from the previous call are like reverted and didnt happen (like as the second call would take place before the first which is obviously not the case). This is extremly strange and i wonder how this is even possible, because i dont think i access the entity from somewhere else. Somenone know why this could happen?

Are you sure that you're not looking at a client side update and a server side update?

Yes, it actually happens on the Server Side, so it cannot be a syncing issue as well, but when it happens on the server side it does on the client on the exact same tick as well everytime.

What I mean is, just because the code updated on the server side does not mean that those values have propagated to the client.

Yes i know. I'm sorry, I think i have expressed myself too ambiguous.

I looked at both sides independently and the problem persist between two calls on the same side.
