Strange trigger ability

[baj6]

Hi i need help making an ability via triggers and im hopeless on triggers it's impossible for me to do without instructions..
anyway, it goes like this:

I have 2 types of enchanted gemstones that is blokking the way through the mess in a logical way.
One pedastal of the horn that switches which one of the types that is: invisible, walkable and not walkable. (if the first one is on, the other one disappears, and the other way aroung.) I need some suggestions on how i should do this..

i tried to attach a drawing where there is s for start and e for exit. purple and yellow circles for the "blokkers" and a blue cross for the "Changer"
When you reach the Changer it changes from yellow to purple and form purple to yellow if thats the chase.. As you can see there is a logical solution but on my map it's bigger and more confusing.. just need the trigger.. if you can help ?? thx in advance..

Just Move/Create path blockers at the center of your "yellow" or "purple" spots, and add a bolean cheking variable ?

Like you activate the yellow switch :

Check if Yellow isnt already up in "If YellowBlocked = TRUE"
, Open the yellows, Block the purples
Set Yellowblocked = False
