Next time please use the Code Playground and post a link to it instead of writing the code out.

Sololearn has code playground for a reason. It can run basic codes. Perhaps you can post questions asking here "Why does my code not work" if it doesn't work

You need at least declare flying,dagger vars before passing them as parameters.
