In this tutorial series, we are going to work on a first person rappel system. Here we will create a special actor blueprint that will act as a rappel point and we can place it in the game world anywhere we like. In the runtime, player will be able to attach a rope to these points and climb up or rappel down on the rope.
If player reach the bottom of the wall, or any time at the middle, player can release the rope and fall on the ground.
