#Kismet

Set of scripts that facilitate vector math in kismet!

5 scripts, all kismet nodes that help with vector math stuff. Base kismet lacks vector math nodes so I made a few.

  • Add vector
  • Multiply vector
  • Get direction vector (returns a vector that points from start to end location)
  • Lerp float
  • Normalize vector

All pretty self explanatory! If you enjoy building game-play in kismet (like I often do) then you will probably find these scripts useful!
