Can you help me to analyze this problem? I'm thinking about make a script that can calculate the vector of thrusting, so when I combine the use of IR, it can make the thrust vector adaptive to the center of mass. As what I know, probably I can do it by collecting the facing and current thrust data of all active engines, and calculate the resultant vector. So, do you agree with it? and can it be more simple? or, is there a function I missed that can get that?
