Your y# doesn't change, try this:




Or this, which is tidier but harder to read:

You need to get the yangle and store it in yr# in the do loop



Otherwise yr# will always be 0 and the reason it rotates a bit is because he reads this:

Wrapvalue simplay takes a number and converts it to an angle within 0-360 degrees.

Example:

wrapvalue(50) will return 50
wrapvalue(-10) will return 350 (360-10)
wrapvalue(400) will return 40 (400 is 40 degrees too high, round it off)

Here's how the wrapvalue command works.


Where "%" represents the modulus symbol. (i dont think DB has that)

ye can make a mod function easily:

function mod(nr#,nrr#)
endfunction nr#-(int(nr#/nrr#)*nrr#)

My code is messed up. i can't even remember if modulus returns the remaind of a division, or the number of times number2 goes into number1. But the following code works as a wrapvalue command.
