Hi,

I’m a beginner, i want to know if there are better way to handle this kind of situations, if in the future the game will be bigger, this kind of workflow can cause some performance issues? Thanks in advance.

if (scriptMovement.IsGrounded() && scriptMovement.horizontal == 0 && !scriptMovement.isShooting)
{
	ChangeAnimationState(Player_Idle);
}
else if (scriptMovement.IsGrounded() && scriptMovement.horizontal < 0 || scriptMovement.IsGrounded() && scriptMovement.horizontal > 0)
{
	ChangeAnimationState(Player_Run);
}
else if (!scriptMovement.IsGrounded() && rb.velocity.y < 0 && !scriptMovement.isWallSliding)
{
	ChangeAnimationState(Player_FallOff);
}
else if (scriptMovement.isJumping)
{
	ChangeAnimationState(Player_Jump);
}
else if (scriptMovement.isWallSliding && scriptMovement.WallSlide)
{
	ChangeAnimationState(Player_WallSliding);
}
else if (scriptMovement.isShooting == true)
{
	ChangeAnimationState(Player_Shooting);
	Debug.Log(1);
}

You use a finite state machine (FSM) using enums and a switch statement.
enum States{
IDLE,
RUN,
JUMP,
FALL
}

 States state;
 
 switch(state){
 case IDLE:
 break;
 case RUN:
 break;
 case JUMP:
 break;
 case FALL:
 break;
 default:
 break;
 }

kind of like that.
