Sorry it took me a while, but I eventually got everything working.
This is a big internal update, you hopefully won't notice much of a change.
But let me know if you find any new issues, because I'm pretty sure I missed alot. ;p

I added a new configuration option, so be sure to
/throwablefireballs updateconfig after you update the plugin.

If you want to add it manually:

Code (YAML):

# Don't want it to look like a FireCharge?
# Change the type of the Fireball item.
FireballItem : "fire_charge"

 

That is the Item MATERIAL name, if you enter an invalid type, the plugin will default to Material.FIRE_CHARGE

I finally solved a huge issue where thrown fireballs with your back to a wall or corner, would cause it to explode in your face instead of throwing it outwards.

There is a known problem where the protected blocks won't explode even if triggered by tnt or another plugin/mob throwing an explosive.
I can't solve this because of limitations in the Spigot API. So if you don't want certain blocks to be completely immune to explosions, just clear the list in the config.

That's about it! If you enjoyed please leave me a rating and follow me on spigot for more updates and plugins.

Have a wonderful week!
