/* 
Simple function that handles player options. These options simply follow the player at an offset - they do not have any trajectories of their own like spinning around the player, etc.
If the options have animations, set triggeranimation to true and adjust the number of frames + speed using delay and frameno.
If the options rotate (in place), set triggerspin to true and adjust spinning speed using spinspeed.
If the options only appear unfocused or focused, set either onlyFocus or onlyUnfocus to true. Setting both to true or false makes the options always visible.
