If you are open to larger suggestions, maybe a way to add a item id/name to the config to some other items from some other mods and it could protect damage from their explosions. But I also think that might require alot more work than intended and possibly some bugs that will come around. But If you did do something like that and graduate it to more of a protection mod, I could see some very nice additions, but I do know that this is suposed to only be a IC2 addon, but I thought id run these next two things by you:
------------------------------ Suggestion if there was to be a more generic "protecion mod":
#1
I have been looking for a way to make a specific block be completely indestructible to explosions like not even disappear for a second. But only for the the certain block I am interested in protecting.
And the item I was looking to protect completely is the grave from openblocks. Because sometimes when you get killed by a creeper, the death places a grave, but the explosion from the creeper that killed you was still happening when the grave was placed so it was destroyed aswell. Which is very frustrating from both a user view and a server owner view.
(the plugin: Towny lets blocks be destroyed, to allow the affect of damages which is really cool, but then it will slowly regenerate the area back, but if the grave is destroyed/deleted the contents are destroyed, and it will get replaced after a few seconds with an empty inventory)
#2
Some other mod items that I wish my server had protection for are the rocketlauncher from MFR(Minefactory Reloaded) and the needlegun
I just ban them since I can't control the use of the explosive and fire ammo, aswell as the "anvil ammo: which is dumb as hell"(places anvils in the location that you shoot)
but the needle gun is very useful for handling the amount of zombies and monsters we have.
------------------------------
But anyways If you aren't into that idea or want to attempt something like that, Someone has already asked if it is possible to add the ic2 dynamite or any of the other ic2 dropable/right click detonate-able items to also have protection. And I think it would be very useful.
