So I am using this code to check if a player is flying: Code (Text): if (sender.isFlying() == true) { sender.setFlying(false); } else { sender.setFlying(true); } The problem is when they are in SURVIVAL mode it will error out in game 'An internal error occurred when attempting to perform this command' - It works if they are in CREATIVE although they can just double jump and then they're back into fly mode instead of typing /fly. EDIT: I've also tried removing the == true, still same error.
When you see this error in game it means you need to look in cosolen to get detailed information about the issue. There will be a nice stacktrace outlining exactly what went wrong, and where.

THANK YOU! Fixed, I better start reading the errors more edit: I have this weird glitch where if they are standing still and they do /fly it will always enable it for them?
@ Moderance also u can check the error line : at test.moderance.commands.Fly.onCommand(Fly.java:36) ~[?:?] its very very usefull ^^
