        rotation *= Time.deltaTime;

            animator.SetTrigger("isJumping");
        }

if(translation != 0)
        {
            animator.SetBool("isRunning", true);
            animator.SetBool("isIdle", false);
        }
        else
        {
            animator.SetBool("isRunning", false);
            animator.SetBool("isIdle", true);
        }
    }

// Custom action method
    public void PerformCustomAction(string actionName)
    {
        animator.SetTrigger(actionName);
    }
}
```
This script creates a basic third person character controller. You can add custom actions by calling the `PerformCustomAction` method and passing the name of the trigger in the animator controller.
