[Failender]

that sounds cool

[Failender]

You extend the class EntityArrow just to copy paste all of it.. So this will sound rude buuuuuut.. learn java.

[nicolas1410]

Can't you just even say "Do that.." than say things like learn java.

 

Just explain a bit to let me understand.

 

[Failender]

If you would know what extending a class means you wouldnt be asking this to me right now.

The point is you cant write a propper minecraft mod without knowing java.

[nicolas1410]

I know the base of java, I just don't always understand how minecraft works. Is there bad intention for asking help?

Plus, it's my first mod ever.

[coolAlias]

What is your question? It's not clear from your post what exactly isn't working as intended.

 

Also, as others have pointed out, you would benefit greatly from learning more about Java - in this casae specifically, I'd recommend learning about inheritance. Then you'll understand why it doesn't make any sense to 'extend EntityArrow' and the copy the entire contents of EntityArrow into your class.

[nicolas1410]

Thank you for your answer. I know why I should extends.

 

My problem is : My entity arrow doesn't spawn correctly, it appears on me.

[coolAlias]

If you know why you should extend a class, then you should know why you would get rid of 90% of that code and replace it with calls to super or not override the method at all.

 

If the arrow is spawning on you, that is a problem with how you create and initialize the entity instance, either in your constructor(s) or in the code that spawns the entity.
