And uh, accelerator...
But no, they don't
You'd just have to make a device that acts as ammo for tha cannon!

I say you make it... NAO!

... SOooo... If we do make a W&OADTS (Weapons & Ordanance Acceleration Driven Transit System)... Then I am so making a looping dynamic grenade defense system... =D

Nades going through all at the same time... lawlwin

I'll think about contributing sprites to an in-base transport system if someone can devise a way to defy gravity and lag without shredding brains and actors through walls (buggy high velocity objects and particles).

I already have sprites, and a method for avoiding actor shredding.

I'll make it when my exams finish.

Emitters on the floors? If that's the case, my only concern would be lag in larger setups.
