Arrow Rendering

[yesod30]

Hi all, i have a problem with rendering a custom arrow entity. If i shoot it 6 block or near the block i aim, the arrow is rendered in the wrong position. In the spoiler i put two image to explain myself better.

EntityArrow Class: http://pastebin.com/wNX8imZy

RenderEntityArrow Class: http://pastebin.com/Sp0yL7qF

 

i registered the entity with:

EntityRegistry.registerGlobalEntityID(EntityExplosiveArrow.class, "explosiveArrow", EntityRegistry.findGlobalUniqueEntityId());
EntityRegistry.registerModEntity(EntityExplosiveArrow.class, "explosiveArrow", 1, Yesodmod.instance, 100, 50, true);

change your number 50, to 1 and get rid of your find unique entity id.

Still have the issue, after they hit or after 1 sec they hit they are rendered in the wrong position.

What version

Try add these code at the begin of your onUpdate() method. That means, Do not move your arrow entity at the first tick it spawns.

	if(this.ticksExisted == 1) {
		if(!worldObj.isRemote) {
			this.throwerLastX = thrower.posX;
			this.throwerLastY = thrower.posY;
			this.throwerLastZ = thrower.posZ;
		}
		return;
	}

This actually work, ty. Just a question: why without it the arrow was rendered in the wrong position?

I don't know whether it's a bug or intentional. I used to meet this problem, and read the codes, trying to find out why this happens. Finally I found it. In a words, an entity except EntityArrow doesn't transfer its moving information to client in its first tick. So if it moves, entity in client is always behind that in server, which causes a wrong position.

It's strange, since i actually copied the code from vanilla arrow . Well, it works, so it's ok i suppose
