I have a rocket similar to a Delta 4. The side boosters and core stage ignite as one on the pad. Once the side boosters run out of fuel, they are discarded. Once the core stage runs out, it's discarded and the second stage takes over. Has anyone written a launch program for that rocket? What I need to know is how to write commands for the boosters and core to ignite on the pad and burn for 5 seconds before being released from the pad. My rocket is attached to the pad with an interstage section.

    @Oski to check when the boosters run out you can just wait untill the max engine thrust drops below the value you would have with all engines active.

    @Oski Thanks, I'll try that with a simpler launch vehicle and see what I can get done.

    Umm,
    Activate stage (engines)
    Wait 5 seconds
    Activate stage (release)
    To make the boosters separate manually launch the rocket and see what's the TWR after they run out, input:
    Wait untill TWR > the number you get
