Ok so implemented this and from my understanding this is saying " when the player comes in contact with the box object" - "Check to see first if at that time he is falling" - "IF he is falling, then check to see if he is ABOVE the box on the Y axis"
If all is true destroy the box.
when I play this - I can't get the box to destroy i'm standing on top the darn thing jumping and falling on top of it.. I'm clearly above it and clearly after jumping i'm falling
