Prologue: Whats the problem? What I want to do now is simualte the flight for a self propelled unguided rocket like titan or rpg. The values I need r given by CfgAmmo an here they are: initTime - How long (in seconds) the projectile waits before starting it's motor. maxSpeed - Declares the maximum speed (metres per second). thrust - Engine power for missiles and rockets. thrustTime - Engine burn time for missiles and rockets. but as I tried to get it all from CfgAmmo I got the following values for titan and RPG: weapon initTime maxSpeed thrust thrustTime ---------------------------------------------------- titan | 0.25 s || 200 m/s | 130 ? | 3 s ---------------------------------------------------- RPG | 0 ||||||||| 140 ||||| 0.1 ||| 0.1 the values for titan r looking good but I cant do anything with the values for RPG... How can I get the correct values for every self propelled weapon? An another big question, what is the unit of thrust?
