Any solid body turned to an energy type in lua will stay without motion.
I just recently found out if you turn a solid that isn't in motion into neut or phot or elec won't move and will be still no matter what heat or pressure you add to it.
@ZER02541714(View Post) Yes, motion is controlled by VX and VY, if the particle is a solid both values are zero. Energy moves because it spawns with VX or VY variables greater or lesser than zero.
