(solved)Custom Fishing Rod not retracting

[Xwaffle]

Well I am making a custom Fishing rod, and the EntityHook is thrown out perfectly fine, but when I try to retract the fishing rod this is what happens.

 

 

 

 

 

It just keeps throwing out a new entity. I could use some help.

 

 

The only class I think that should be needed is the Entity Class.

I had an idea  of maybe trying onItemRightClick if Entity(or bobber? idk) != null set Entity(or bobber?) to dead.

 

[Xwaffle]

Anyone got any idea to why I got this issue?

[Xwaffle]

Got a  lot of views but n answers

[Xwaffle]

Bump

[ObsequiousNewt]

Could we see the item class? Methinks the problem lies in creating the rod.

Can do! Here is the class!

 

 

 

 

 

[Xwaffle]

Also That's not a double onRightClick thought i'd let you know

[Xwaffle]

 

was hoping it would work if I spammed it! jk

[ObsequiousNewt]

You're using EntityPlayer.fishEntity to tell whether you have a rod out (just like the normal fishing rod, but it seems you might run into problems), but you're never setting it to true when you spawn the hook. Fixify that!

[Xwaffle]

Well fishEntity is not a boolean so I can not set it to true nor false. I did try setting it  equal to null and != null but those did not work. I tried placing it in two different places

 

 

 

 

 

Another thing though fishEntity is not the rod its self it's actually an instance of a fishing rod's hook. If this isn't null, the icon image of the fishing rod is slightly different.

 

Another idea please? I really need this working.

Er, not "true". But in the constructor of EntityFishHook there is a line that says "this.angler.fishEntity = this;". Since you're missing that line, angler.fishEntity keeps showing up as null.

 

However, EntityPlayer.fishEntity is type-protected to EntityFishHook. Which you don't extend. So you will need to alter your class to extend EntityFishHook, or else use IExtendedEntityProperties.

[Xwaffle]

Alright I added the lines.

 

 

 

 

 

but NOW I get an instant crash on right click. The error is a Ticking Entity

 

 

 

 

 

EntityFishHooks lines

 

 

 

 

Here are the lines that are needed from the crash report.

 

 

 

http://and EntityOldHook lines

 

 

 

[Xwaffle]

Alright did some tinkering and well the rod works  now and it retracts, but now I have a new issue. when I run the world the first time. everything works PERFECT if I use the rod it works too, but if I close Minecraft and reopen it. The world crahes on starting the world.

[xwerswoodx]

I have same problem, I didn't want to start new topic,

 

I open the game, and I use fishing rod but not pull it off, and save game and close, but when I restart game and try to join world, it gives this crash;

187. line is;

 

187.				ItemStack itemstack = this.angler.getCurrentEquippedItem();
188.				
189.				if (this.angler.isDead || !this.angler.isEntityAlive() || itemstack == null || !isNewFishingRod(itemstack) || this.getDistanceSqToEntity(this.angler) > 1024.0D) {

and also maybe you need;
