Cisano Posted July 9 Share Posted July 9 Hi. I have a problem with my last game. I use RESMP0 to lock and unlock the missile with GRP0. When I shot the missile HMM0 is #%10010000 and NUSIZ0 is #%00110000 and all work great. My problem is the missile starts far from its GRP0 (see the pic) Is it normal that distance? Thanks.
