Launch a stick

Simple game-mechanic that works by launching in-air the stick item giving to it a physics
you press RMB mouse key while holding the stick in your right hand, if you have a domestic dog near you, you show to him the stick and launch it in any direction, there is a chance that the dog will go to take it otherwise it will stay still and look at you in a confused manner

Launching the stick could open also other game-mechanics like redstone activation by launching a stick on strings, buttons and plates
There really endless feature by just adding something that literally copies the arrow physics but it just has less power for travel far

I leave the choice to game devs if they want the stick to deal damage or not
