Need some basic KOS help (loops)

[ToukieToucan]

I'm pretty new to KOS so I have a few questions:

 

Lets say we use this code

Spoiler

//hellolaunch

//First, we'll clear the terminal screen to make it look nice
CLEARSCREEN.

//Next, we'll lock our throttle to 100%.
LOCK THROTTLE TO 1.0.   // 1.0 is the max, 0.0 is idle.

//This is our countdown loop, which cycles from 10 to 0
PRINT "Counting down:".
FROM {local countdown is 10.} UNTIL countdown = 0 STEP {SET countdown to countdown - 1.} DO {
    PRINT "..." + countdown.
    WAIT 1. // pauses the script here for 1 second.
}

//This is a trigger that constantly checks to see if our thrust is zero.
//If it is, it will attempt to stage and then return to where the script
//left off. The PRESERVE keyword keeps the trigger active even after it
//has been triggered.
WHEN MAXTHRUST = 0 THEN {
    PRINT "Staging".
    STAGE.
    PRESERVE.
}.

//This will be our main control loop for the ascent. It will
//cycle through continuously until our apoapsis is greater
//than 100km. Each cycle, it will check each of the IF
//statements inside and perform them if their conditions
//are met
SET MYSTEER TO HEADING(90,90).
LOCK STEERING TO MYSTEER. // from now on we'll be able to change steering by just assigning a new value to MYSTEER
UNTIL SHIP:APOAPSIS > 100000 { //Remember, all altitudes will be in meters, not kilometers

    //For the initial ascent, we want our steering to be straight
    //up and rolled due east
    IF SHIP:VELOCITY:SURFACE:MAG < 100 {
        //This sets our steering 90 degrees up and yawed to the compass
        //heading of 90 degrees (east)
        SET MYSTEER TO HEADING(90,90).

    //Once we pass 100m/s, we want to pitch down ten degrees
    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 100 AND SHIP:VELOCITY:SURFACE:MAG < 200 {
        SET MYSTEER TO HEADING(90,80).
        PRINT "Pitching to 80 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    //Each successive IF statement checks to see if our velocity
    //is within a 100m/s block and adjusts our heading down another
    //ten degrees if so
    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 200 AND SHIP:VELOCITY:SURFACE:MAG < 300 {
        SET MYSTEER TO HEADING(90,70).
        PRINT "Pitching to 70 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 300 AND SHIP:VELOCITY:SURFACE:MAG < 400 {
        SET MYSTEER TO HEADING(90,60).
        PRINT "Pitching to 60 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 400 AND SHIP:VELOCITY:SURFACE:MAG < 500 {
        SET MYSTEER TO HEADING(90,50).
        PRINT "Pitching to 50 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 500 AND SHIP:VELOCITY:SURFACE:MAG < 600 {
        SET MYSTEER TO HEADING(90,40).
        PRINT "Pitching to 40 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 600 AND SHIP:VELOCITY:SURFACE:MAG < 700 {
        SET MYSTEER TO HEADING(90,30).
        PRINT "Pitching to 30 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 700 AND SHIP:VELOCITY:SURFACE:MAG < 800 {
        SET MYSTEER TO HEADING(90,11).
        PRINT "Pitching to 20 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    //Beyond 800m/s, we can keep facing towards 10 degrees above the horizon and wait
    //for the main loop to recognize that our apoapsis is above 100km
    } ELSE IF SHIP:VELOCITY:SURFACE:MAG >= 800 {
        SET MYSTEER TO HEADING(90,10).
        PRINT "Pitching to 10 degrees" AT(0,15).
        PRINT ROUND(SHIP:APOAPSIS,0) AT (0,16).

    }.

}.

PRINT "100km apoapsis reached, cutting throttle".

//At this point, our apoapsis is above 100km and our main loop has ended. Next
//we'll make sure our throttle is zero and that we're pointed prograde
LOCK THROTTLE TO 0.

//This sets the user's throttle setting to zero to prevent the throttle
//from returning to the position it was at before the script was run.
SET SHIP:CONTROL:PILOTMAINTHROTTLE TO 0.

from here .

 

When it enters space I want to add some code:

lock steering to prograde.
wait until eta:apoapsis < 30.
lock throttle to 1.
wait until eta:apoapsis > 50.
lock throttle to 0.
wait until periapsis = 100000.

How do I make this a loop and how do I deactivate the loop when Periapsis is = 100000?

[ToukieToucan]

GLOBAL throt IS 0.

LOCK THROTTLE TO throt.

LOCK STEERING TO PROGRADE.

UNTIL PERIAPSIS >= 100000 {

IF ETA:APOAPSIS < 30 AND throt < 1 {

SET throt TO 1. }

IF ETA:APOAPSIS > 50 AND throt > 0 {

SET throt TO 0. }

WAIT 0.

}

UNLOCK STEERING.

UNLOCK THROTTLE.

Modding question moved to the modding subforum.

You asked the exact same thing over in the kOS reddit group, and it seems to be getting more traction there.

(Just mentioning here for posterity in case anyone sees this thread and wants to know where the conversation went from here so it doesn't look like it just died and went un-responded to.)
