Unity3D 一個設置方向鍵移動和空格起跳的腳本

Unity3D 一個設置方向鍵移動和空格起跳的腳本：

1. /// This script moves the character controller forward
2. /// and sideways based on the arrow keys.
3. /// It also jumps when pressing space.
4. /// Make sure to attach a character controller to the same game object.
5. /// It is recommended that you make only one call to Move or SimpleMove per frame.
7. var speed : float = 6.0;
8. var jumpSpeed : float = 8.0;
9. var gravity : float = 20.0;
11. private var moveDirection : Vector3 = Vector3.zero;
13. function Update() {
14. var controller : CharacterController = GetComponent(CharacterController);
15. if (controller.isGrounded) {
16. // We are grounded, so recalculate
17. // move direction directly from axes
18. moveDirection = Vector3(Input.GetAxis("Horizontal"), 0,
19. Input.GetAxis("Vertical"));
20. // 這裡獲取了鍵盤的前後左右的移動，但注意，這是相對於自己的。
21. moveDirection = transform.TransformDirection(moveDirection);
22. // 還有一個TransformPoint。這裡是把相對於自己的
23. // 坐標轉換為相對於世界的坐標。
24. moveDirection *= speed;
26. if (Input.GetButton ("Jump")) {
27. moveDirection.y = jumpSpeed;
28. }
29. }
31. // Apply gravity
32. moveDirection.y -= gravity * Time.deltaTime;
34. // Move the controller
35. controller.Move(moveDirection * Time.deltaTime);
36. }
