Non-living Entities not spawning correctly

Shadow Ryusaki · August 30, 2012

I recently switched to Forge, since I was running out of space for icons and such so I am a little new with this. However, my Error seems to be a little strange. Whenever something like my custom bow or a knife is thrown it doesn't spawn into the world correctly. if I leave !world.isRemote like it is I can't see my arrows/throwables, but they still work like they are supposed to. However, if I take out the ! then I can see my pictures, however they do no damage whatsoever. They even just bounce off the mobs or if they explode they do no damage. I have a lot of items, so I will just post the three important ones.

This same problem goes for items that use icons to render, although the icons that are used sometime appear as something completely different... like Chain Boots. Hopefully this is enough information to help. This and my teleporting glitch is screwing up my game without giving actual errors, but that other glitch is for another time.

I see nothing showing you registering your entities for tracking.

And make sure you're on the latest forge before reporting anything.

And make sure you've follow the proper tutorials for things.

I see nothing here that shows me:

Registering your Entity tracker info

Setting your textures

Shadow Ryusaki · August 30, 2012

There we go, edited my first post. Hopefully that is the correct one (unless I am missing one more thing for that....) As for the textures, inside ItemBlueKnife there is the normal getTextureFile. I have it to where my public static is looking into the file I created for it.

public static final Item blueknife = new Itemblueknife(3050).setIconIndex(36).setItemName("Blue Knives");

Seems I did forget to Register it as a tracker. I did it now, I think, but still get no damage.

Edit: And I do have the latest Forge installed.

Editedit: Or so I thought... seems There was an updated build not too long ago. Let me try it.
