HIERARCHICAL STATE MACHINE

  • Based on basic finite state machine, but more scalability and more provide to make various states with organic transition with other states.

​

  • The Structure looks like Base State -> Type state -> Implement state.

​

  • Base State is for organizing and managing with another state.

​

  • Type state is more concept state for implementing concrete state.

​

  • Implement state is really acting which I want to play or do some actions.

FLOATING CAPSULE

  • Two types of player standing with ground which is Floating Capsule and using Capsule collider fully charge of player’s height.

​

  • I used floating capsule for fixing sophisticated movement parts which are slope, stairs, terrain, and other ground environment.

​

  • Using some mathematical code, Calculate whether the player can stand on the ground.

CAMERA RECENTERING

  • Motivated by the Genshin Impact game.

​

  • Simple concept is if player move to horizontally then the camera will recentering to player.

​

  • This will make if player move horizontally then the player will move as a circularly.

ROOT MOTION

  • More make realistic movement with animation.

​

  • The animation affected to character transform.

​

  • But it can make some bugs with control transform code, so we should be taking care of this problem.

​

  • Also, the character physics is affected by the animation which means that the collider can be changed position, rotation, and scale.

BLEND ANIMATION

  • More make animation smooth when transitioning with other states.

​

  • Different animation will blend smoothly.

​

  • More make character animation looks cool.

IK SYSTEM

  • Change character bones with code.

​

  • Makes more realistic interaction with physics object.

​

  • Access to character model’s bones and change the model’s transform with code.
