Custom arrow spinning madly

[Bedrock_Miner]

Heyho Guys!

I created a custom bow for custom arrows. The problem with this thing is, that the arrows rotate while they are flying, but only if the player is in survivalmode. Basically the entity just extends EntityArrow without changing any thing of the movement. I didn't attach a renderer, the default one is used instead.

Code of the Arrow:

public class EntityMagicArrow extends EntityArrow {

public EntityMagicArrow(World world) {
	super(world);
}

public EntityMagicArrow(World world, double x, double y, double z) {
	super(world, x, y, z);
}

public EntityMagicArrow(World world, EntityLivingBase source, EntityLivingBase target, float f1, float f2) {
	super(world, source, target, f1, f2);
}

public EntityMagicArrow(World world, EntityLivingBase source, float speed) {
	super(world, source, speed);
}

@Override
public void onUpdate() {
	super.onUpdate();
	//No Gravity
		this.motionY += 0.049999;
		this.motionX /= 0.99;
		this.motionY /= 0.99;
		this.motionZ /= 0.99;
		if (this.posY > 512)
			this.kill();
}
}

Hi

 

It looks to me like you are trying to undo the motion effects of Entity arrow by guessing what onUpdate did and then undoing it. 

The reason your arrow is still spinning is because you undo motion but not rotation.

 

I'd suggest the best way to do this is to save a copy of the motionX, Y, Z and the rotationPitch and rotationYaw and overwrite them again afterwards if the arrow hasn't stuck in the ground or bounced off an entity or been destroyed or similar

 

so eg

 

{save motion and rotatino variables}

super.onUpdate()

if (! inGround && ticksInAir != 0)

{copy variables back}

Yes, this can be the reason, thanks. Only one problem: inGround is private, so I need to use reflection again...

 

I'll try and let you know of it works.
