So fügen Sie dem Character Controller in Unity Unterstützung für bewegliche Plattformen hinzu

Dieses Tutorial zeigt, wie man eine bewegliche Plattformunterstützung für den CharacterController in Unity hinzufügt.

Also fangen wir an!

Schritte

• Platzieren Sie Ihren Character Controller in der Szene
• Erstellen Sie ein neues Skript, nennen Sie es "SC_MovingPlatform" und fügen Sie den folgenden Code ein:

SC_MovingPlatform.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SC_MovingPlatform : MonoBehaviour
{
    public Transform activePlatform;

    CharacterController controller;
    Vector3 moveDirection;
    Vector3 activeGlobalPlatformPoint;
    Vector3 activeLocalPlatformPoint;
    Quaternion activeGlobalPlatformRotation;
    Quaternion activeLocalPlatformRotation;

    // Start is called before the first frame update
    void Start()
    {
        controller = GetComponent<CharacterController>();
    }

    // Update is called once per frame
    void Update()
    {
        if (activePlatform != null)
        {
            Vector3 newGlobalPlatformPoint = activePlatform.TransformPoint(activeLocalPlatformPoint);
            moveDirection = newGlobalPlatformPoint - activeGlobalPlatformPoint;
            if (moveDirection.magnitude > 0.01f)
            {
                controller.Move(moveDirection);
            }
            if (activePlatform)
            {
                // Support moving platform rotation
                Quaternion newGlobalPlatformRotation = activePlatform.rotation * activeLocalPlatformRotation;
                Quaternion rotationDiff = newGlobalPlatformRotation * Quaternion.Inverse(activeGlobalPlatformRotation);
                // Prevent rotation of the local up vector
                rotationDiff = Quaternion.FromToRotation(rotationDiff * Vector3.up, Vector3.up) * rotationDiff;
                transform.rotation = rotationDiff * transform.rotation;
                transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);

                UpdateMovingPlatform();
            }
        }
        else
        {
            if (moveDirection.magnitude > 0.01f)
            {
                moveDirection = Vector3.Lerp(moveDirection, Vector3.zero, Time.deltaTime);
                controller.Move(moveDirection);
            }
        }
    }

    void OnControllerColliderHit(ControllerColliderHit hit)
    {
        // Make sure we are really standing on a straight platform *NEW*
        // Not on the underside of one and not falling down from it either!
        if (hit.moveDirection.y < -0.9 && hit.normal.y > 0.41)
        {
            if (activePlatform != hit.collider.transform)
            {
                activePlatform = hit.collider.transform;
                UpdateMovingPlatform();
            }
        }
        else
        {
            activePlatform = null;
        }
    }

    void UpdateMovingPlatform()
    {
        activeGlobalPlatformPoint = transform.position;
        activeLocalPlatformPoint = activePlatform.InverseTransformPoint(transform.position);
        // Support moving platform rotation
        activeGlobalPlatformRotation = transform.rotation;
        activeLocalPlatformRotation = Quaternion.Inverse(activePlatform.rotation) * transform.rotation;
    }
}

• Hängen Sie das SC_MovingPlatform-Skript an das Objekt mit der Character Controller-Komponente an

Die bewegliche Plattformhalterung ist jetzt fertig:
