我的統一3dfps運動正在穿過墻壁，它們都有碰撞器

我遇到的問題是當我全速運行（即按下 a 和 w 并向右看 45 度時，它不會故意使用 .normalized）撞到墻壁或其他任何允許玩家穿過它的東西，所以我的代碼是

Vector3 m_Input = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
Vector3 moveDirection = m_Input;
moveDirection = transform.TransformDirection(moveDirection);
rb.MovePosition(transform.position   moveDirection * moveSpeed);

并moveSpeed設定為0.2。我已經檢查過了，所有的對撞機都不是觸發器。任何幫助將不勝感激

首先做雙重檢查

• 你所有的對撞機和剛體都是 3d
• 一切都在同一層上（或者您的層設定為相互互動）
• 您的剛體與您的??對撞機連接到同一個游戲物件

但是，您的問題似乎是您rigidbody的設定為運動學（因為Rigidbody.MovePosition僅供運動學剛體使用）

如果您rigidbody設定為，kinematic則不會對您的物件施加任何力（例如對撞機法向力），因此它將能夠穿過墻壁。

解決方案

避免這種情況的最簡單方法是確保將剛體設定為非運動學，然后通過Rigidbody.velocity.

類似于：

Vector3 m_Input = new Vector3(Input.GetAxis("Horizontal"), 0, 
Input.GetAxis("Vertical"));
Vector3 moveDirection = m_Input;
moveDirection = transform.TransformDirection(moveDirection);

rb.velocity = (moveDirection * moveSpeed);

這應該根據物理移動您的角色，并允許與對撞機進行正確的互動。

此外，您應該知道，如果您確實想要移動這樣的剛體，您應該確保這樣做FixedUpdate并按Time.FixedDeltaTime.
