Wow thanks heaps Geti that spelt it out rather well
Thank you to Coop you set me on the right track so in the meantime between yours and Geti's post i did some reaserch and now i mostly know what he was talking about.
To true the vanilla C4 doesn't cut it (way to CPU intensive with the fire, for me at least). Nor the explosive charge really. So i am on a quest to make my own, plus bombs are way cool!
Blow ♥♥♥♥ up!! With some luck i may be back with some sort of mod to post if its any good, but that will probably be a century later knowing the countless nooby hurtles that lay ahead haha.
