fires the metaphorical hook and moves

• to detected hit position under crosshair, center.

  • moves player with onUpdate via event to global

• uses key c at first and weapon swing later, global staying the same.

• usig camera package restricts this to player.

• variable active is used to prevent using hook midfly

  • and ropagating the state for frames making the script simpler

<aside> 💡

For prevent hitting the player { ignore = self } need to be used in both case

resulting to castray for weapon, using onUpdate

and for example castRenderingRay for key, needing also onFrame handler.

</aside>

• this could be improved turning the player to flying direction
  • or using self.rotation for adjusting the hook direction

hitting terrain is possible removing or commenting

if result.hitObject == nil then active = 0 return end

also need larger hitting distance, say 300 units, to prevent going trought.
