Features

You can:

• Define how strong any block types resist the explosion.
• Define which blocks allow to propagate the explosion but do not get destroyed.
• Define which explosions to replace.
• Modify the explosion radius and damage.
• Confine the explosion to a range of y coordinates (0.2.0), also per world settings.
• Modify radius and extra damage for living entities to get damaged.
• Modify how strong armor depletes if hit by explosions.
• Damage entities only in places where the explosion really reaches to (not behind obsidian walls for instance, if configured so).
• Remove items (random yield).
• Explosions can influence projectiles and arrows (items). But also trigger other tnt (both blocks and items).
• Tnt items can also become primed tnt if ignited (lava, fire... configurable.)
• Currently explosions can not propagate diagonally (technically), so no need not fill every corner to create a safe spot.
• Rely on protection plugins: Block destruction and damage to entities are all treated by firing ordinary events which other plugins can intercept and deny (EntityExplodeEvent, EntityDamageEvent).
• Define what entities in which worlds to handlem or to prevent their explosions, in fact all explosion settings can be set individually for entities/worlds.
• panic command.
• Possibly other...

You might not (yet):

• Exact vanilla minecraft behavior! (probably never...)
• Just control explosions instead of replacing the whole algorithm. (possible: prevent / handle)
• Some other stuff

You might want:

• To customize the configuration entries according to your needs, like multipliers for radius and damage, and block resistence, possibly others - The current configurations is based on wild guessing and probably will not please you !
• Anything else ? Leave a note !
