This plug in is fabulous. I spent a night trying to make a nice launch sequence to launch my 3 staged rocket. I ran into some problems because I attempted to do an auto-staging but, was quite hard to get it working. I had to set variable for liquid fuel being used or not at the current stage because the initial solid fuel boosters were staged by the liquid fuel routine and same for the liquid one. Took me some time to understand what was happening! I had to rotate my ship because the tutorial way made my rocket not rolling to the correct pitch but doing a turn and so being of trajectory... I got another issue trying to mess out with the heading thing and my rocket this time does a 270° turn... so I finally ended up rotating it and using vectors rather than the shortcuts. I would like to know if there's a better way to handle this, maybe i didn't spent enough time reading the documentation. As well, I would like to know if there's a way to set the throttle to 0 or check if it's at 0 before launch, if I don't, when the program terminate, it revert to the previous setting, so you could screw your orbit. Below is the code, please tell me what you think of it. (was my first attempt). P.S. The Ignition/Launching part is to release the clamps 1sec after ignition. CLEARSCREEN. PRINT "Launching sequence. Set your throttle to 0...". WAIT 5. SET cd TO 5. PRINT "Launching in...". UNTIL cd = 3 { PRINT "..." + cd. SET cd TO cd - 1. WAIT 1. }. PRINT "...3 - Throttle and steering locked.". LOCK THROTTLE TO 1.0. LOCK STEERING TO R(0,305,180). WAIT 1. PRINT "...2". WAIT 1. PRINT "...1 - Ignition...". STAGE. WAIT 1. PRINT "...0 - Launching...". STAGE. WAIT 5. PRINT "Rotating...". LOCK STEERING TO HEADING(90,90). SET Liquid TO 0. WHEN STAGE:SOLIDFUEL < 0.10 THEN { IF Liquid = 0 { PRINT "Staging now...". STAGE. SET Liquid TO 1. }. }. WHEN SHIP:ALTITUDE > 10000 THEN { PRINT "Initiating turn. Aiming to 45° pitch...". LOCK STEERING TO HEADING(90,45). }. WHEN STAGE:LIQUIDFUEL < 730.00 THEN { IF Liquid = 1 { PRINT "Staging now...". STAGE. SET Liquid TO 2. }. IF Liquid <= 1 { PRESERVE. } }. WHEN SHIP:ALTITUDE > 40000 THEN { PRINT "Initiating turn. Aiming to 90° pitch...". LOCK STEERING TO HEADING(90,0). }. WAIT UNTIL APOAPSIS > 100200. PRINT "Expected apoapsis altitude > 90km...". LOCK THROTTLE TO 0.0. LOCK STEERING TO PROGRADE. WAIT 2. PRINT "Waiting for circularisation...". WAIT UNTIL ETA:APOAPSIS < 15. PRINT "Beginning circularisation...". LOCK THROTTLE TO 1.0. WAIT UNTIL PERIAPSIS > 99500. PRINT "Circularisation complete...". LOCK THROTTLE TO 0.0. PRINT "CAUTION: Be sure your throttle in off. Terminating in 10 seconds". WAIT 10.
