How to lock pitch with vizzy?

If you go to craft instructions there is a box that says: loch heading on None. You can change the none to whatever you want the pitch to be locked for example, target, current, north, up, down

another way you can try is - "set craft pitch" command, then "wait 1 second" (whatever time it takes the craft to respond), then "lock heading on current". that should hold the heading until you want to change it, then "lock heading on none" to stop it

If you want to make something happens more than once, you need "while" block. Without it the program would run your code only for once. Put any condition you want in while block and set the code inside of it. If you want the code run perpetually, set "while=true".
