I'm making a new bow/arrow for a mod i'm crating but the arrow does not render in world(its still just the default arrow texture so i cant think that thats an issue)

 

Codes and such:

[SanAndreaP]

You need to register your EntityHeroArrow with the EntityRegistry first. It doesn't know what entity it should render if you don't register it.

[dude22072]

so i would use EntityRegistry.what?

[dude22072]

Nevermind. I need to learn to google before i ask.
