I am working on an example mod to examplify how to add blocks, entities, and simple things of that nature such as a block I have coded which faces in all six directions with custom hitboxes.
The only entity modeler I can find is Tabula. Although, I once had this coded somewhere I have looked for about a week or so and went at it at various different angles to add a 2D thrown entity with item although I have accomplished adding 3D ones.
I have a mod that gives you the ability to craft spheres which have entities.
When you right click the item, the entity is thrown and one is subtracted from the item stack.
Here is that src, which is the src for The Basic Elements:
All you have to do is drag the src file into where you've extracted forge and run the build command and the mod builds.
I figure since my mod has spheres someone could work with the code example and add a 2D throwable pebble of some kind or another.
If anyone has any extra time or would like to check out some new code or something and post a src on here with the 2D thrown entity that'd be cool.
The mod I'm working on now has a 3D throwing projectile, an alien blue block, and will feature a extra snowball item and a dagger with a couple of power blocks, that being the goal. I've also recoded the original spike block from Xbox Live way back when and got it working with pistons and sticky pistons both. Which faces in all six directions with custom hitboxes added for alignment in each direction. Also being something I have coded for this individual project.
The difference between my code and the snowball code is that entitySnowball extends entityThrowable.
