I have made some magic armor (gravitite) that allows you to fly, but when I take it off, I can still fly.  I want it to be able to work with other ways of flight though (like Thaumcraft's Thermostatic Harness or Ars Magica's Flight Spell).

Edit: it works properly if I take the gravitite chestplate off and put the Earth chestplate on instead.

My code is:

Any help will be greatly appreciated.

Would you place the code between

?

private boolean isWearingGravitite;

is never set to false.

But you can do without that variable anyway.
