How to predict falling off edge of SM?

Below is how you do it on AnimBP. I used the ThirdPerson template and add the Jump From Ledge anim state:

  1. From ThirdPersonCharacter blueprint:

  • Add IsJumping boolean variable

  • Implement OnJumped event of CharacterMovementComponent

  • Implement OnLanded event of CharacterMovementComponent

  • Together with CharacterMovementComponent’s IsFalling check, we can differentiate falling from ledge vs falling after jump.

  1. From AnimBP Event Graph:

  • Create IsJumping? variable. This is a counterpart variable from IsJumping from the character blueprint

  • At the end of existing anim event graph, add CastToThirdPersonCharacter node, then get its IsJumping variable to set AnimBP’s IsJumping? counterpart variable

  1. From AnimBP AnimGraph → Default

  • Expand the existing AnimGraph

  • Add Conduit conduit node. Conduit lets you branch out to multiple node with similar transtition.

  • Add FallOfLedge state. Set animation to your Fall Off Ledge animation.

  • Connect Idle/Run into Conduit conduit (transition = IsInAir?)

  • Connect Conduit into JumpStart state (transition = IsJumping?)

  • Connect Conduit into FallOfLedge state (transition = NOT IsJumping?)

  • Connect FallOfLedge into Idle/Run state (transition = Time Remaining (ratio) < 0.2)

That should do it. Your Jump and FallOffLedge animation should play properly apart from each other.
