Up/down barriers toggled by crystal switches question

[Pineconn]

To be honest, I feel dumb asking this since a LOT of games I've played incorporate this.

The following screenshots are from Isle of the Winds by DarkFlameWolf:

When you hit the crystal switch with the boomerang, it transforms the screen to this:

Hitting the crystal switch, AGAIN, would bring this up again:

The boomerang hits the switch, raising/lowering the blocks, and you can continue toggling the switches. How do you do this? I would like to know how, if someone is so courteous as to reveal the magic! Thanks in advance. :)

You put the block up and block down in combos 16 and 17.
click on the block in 16 while holding Ctrl down and choose 17 as it's secondary flag, and do the same to combo 17 making 16 it's secondary flag, so every time secrets are triggered they toggle back and forth.

put the orb in the boomer flag and make itself it's secondary flag so it triggers every time it is hit.
You can also make the orb change colors, it requires using 3 orbs.
put blue in boomer, yellow in 18 secret combo and blue in 19 secret combo.
use secondary flags on them to advance 18 to boomer, 19 to 18, and boomer to 19, so each time you hit the orb it advances the next colored orb combo to boomerang slot.

Oh my, I didn't know anything about the secondary flags! I tried it, and it works! I thank you greatly! And, I'll even put your name in the credits of my game!

Thank you very much!

[EDIT] BTW Pineconn, don't feel dumb, everyine was a newcomer at some point, and even experienced questers can still learn new things.

Good luck out there
