[1.6.2] Fishing Rod onUpdate, nullpointer problem

[xwerswoodx]

I copy fishing rod and edit its code. It's working good, but I have some problem. When I use fishing rod (original one) and don't pull it off, I save game and restart. When I join game, it cancelled and working without problem. However, I try same thing for new fishing rods and this.angler return null and game crashes.

 

When I use new fishing rods this works and this.angler = player, return player.

public EntityNewFishHook(World world, EntityPlayer player) {
super(world);
this.xTile = -1;
this.yTile = -1;
this.zTile = -1;
this.inTile = 0;
this.inGround = false;
this.shake = 0;
this.ticksInAir = 0;
this.ticksCatchable = 0;
this.bobber = null;
this.ignoreFrustumCheck = true;
this.angler = player;
this.angler.fishEntity = this;
this.setSize(0.25F, 0.25F);
this.setLocationAndAngles(player.posX, player.posY + 1.62D - (double)player.yOffset, player.posZ, player.rotationYaw, player.rotationPitch);
this.posX -= (double)(MathHelper.cos(this.rotationYaw / 180.0F * (float)Math.PI) * 0.16F);
this.posY -= 0.10000000149011612D;
this.posZ -= (double)(MathHelper.sin(this.rotationYaw / 180.0F * (float)Math.PI) * 0.16F);
this.setPosition(this.posX, this.posY, this.posZ);
this.yOffset = 0.0F;
float f = 0.4F;
this.motionX = (double)(-MathHelper.sin(this.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(this.rotationPitch / 180.0F * (float)Math.PI) * f);
this.motionZ = (double)(MathHelper.cos(this.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(this.rotationPitch / 180.0F * (float)Math.PI) * f);
this.motionY = (double)(-MathHelper.sin(this.rotationPitch / 180.0F * (float)Math.PI) * f);
this.calculateVelocity(this.motionX, this.motionY, this.motionZ, 1.5F, 1.0F);
}

 

But when I restart my game when the rod in use, this not working and return this.angler = null; So game crashes. How can I fix this problem? The problem is;

and the line is;

			ItemStack itemstack = this.angler.getCurrentEquippedItem();

 

I check this section and this.angler return null; So I know the problem is this.angler returns null.

 

Thanks.

It's an NPE, right? If you can, please show all your code that you think is part of the error, not just the constructor. I have an idea, but I need to see the code
