Custom TNT Start Point?

[Krazy]

Hi, I'm looking to make some custom tnt, when it blows up special effects happen. I literally have no idea how I would start with this, I tried using metadata but it didn't seem to work very well. I tried saving to a variable tied to its location when you place, but then there's issues when the tnt is primed it could move or etc. Anyone that has done this/has an idea of what to do? Thanks!

That would do the custom stuff for every piece of tnt..

I did something along the same lines of custom explosions here.

I used metadata, but I was only able to add metadata to the entity if I used the "spawn" expression- not when i used the "shoot" expression. Hopefully this may give some insight on the subject.
