Adding a composite node to autocannons with a few different uses (using different channels):
Channel 1 for number input would tell the autocannon how many meters the projectile should go before self-exploding (only works on HE and Frag).
Channel 2 for number input would set the time in seconds before it will self-explode (only works on HE and Frag).
Assuming both Channel 1 and 2 for number input have a value greater than 0, the value reached first triggers the auto-explode.
Channels 3, 4, and 5 of number input are the RGB values of the color for the projectile tracer.
Channel 1 of Boolean input will set the frag explosion-direction mode: spherical (off) or conical (on).
Channel 2 of Boolean input will set the frag smoke mode: no smoke (off), smoke clouds (on).
-Think along the lines of World War Flak Smoke clouds; those black clouds that blinded the planes and showed the cannon operators where they were hitting.
