Calling motors at the same time C++

[UnnownCanon]

I am having trouble calling all motors (spinning motors all at once) in my 6-motor drivetrain at the same time during the autonomous period in C++. My code so far is:

void autodrive(){
L1.spinFor(reverse,600,degrees)
L2.spinFor(reverse,600,degrees)
L3.spinFor(reverse,600,degrees)
R1.spinFor(reverse,600,degrees)
R2.spinFor(reverse,600,degrees)
R3.spinFor(reverse,600,degrees)
}

I then call it but it moves every motor individually.

Someone else had a similar issue before read this post

Function help, are my numbers wrong? is it something to do with that is true/false

When autonomous is used, the variables seem to not move/ not follow one another. They do one action and all the other variables are skipped. here is an example of a drive forward command and a turn right command anytime they are called, they do not do anything. we have a four motor drive train and want all the motors to work at the same time. float degreesFWD = inchesFWD*35.277; leftMotor1.spinFor(forward, degreesFWD, degrees, false); rightMotor1.spinFor(forward, degreesFWD, degrees, false);…

It has to do with passing a parameter called waitForCompletion and setting it to false.

Thank you so much! This was really helpful!
