Unity3D实现人物移动示例
### 回答1:
我们可以使用以下代码来控制3D人物在Unity中的移动://移动
transform.Translate (Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime, 0, Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime);//跳跃
if (Input.GetButtonDown("Jump")){
rigidbody.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
}//奔跑
if (Input.GetButtonDown("Run")){
moveSpeed = runSpeed;
}//贴墙跑
if (Input.GetButtonDown("WallRun")){
rigidbody.AddForce(Vector3.up * wallRunForce, ForceMode.Impulse);
}//边缘攀爬
if (Input.GetButtonDown("Climb")){
rigidbody.AddForce(Vector3.up * climbForce, ForceMode.Impulse);
}
### 回答2:
在Unity中实现3D人物控制的代码可以如下:
```c#
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CharacterController : MonoBehaviour
{
private bool isRunning = false;
private bool isJumping = false;
private bool isClimbing = false;
private bool isWallRunning = false;
private float moveSpeed = 5f;
private float jumpForce = 5f;
private Rigidbody rb;
void Start()
{
rb = GetComponent<Rigidbody>();
}
void Update()
{
// 移动
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0f, moveVertical);
rb.MovePosition(rb.position + movement * moveSpeed * Time.deltaTime);
// 奔跑
if (Input.GetKeyDown(KeyCode.LeftShift))
{
isRunning = !isRunning;
moveSpeed *= isRunning ? 2f : 0.5f;
}
// 跳跃
if (Input.GetKeyDown(KeyCode.Space) && !isJumping)
{
rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
isJumping = true;
}
// 贴墙跑
if (Input.GetKey(KeyCode.LeftControl))
{
isWallRunning = true;
// 实现贴墙跑逻辑
}
else
{
isWallRunning = false;
}
// 边缘攀爬
if (Input.GetKeyDown(KeyCode.E) && isClimbing)
{
// 实现边缘攀爬逻辑
}
}
void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.CompareTag("Ground"))
{
isJumping = false;
}
else if (collision.gameObject.CompareTag("Climbable"))
{
isClimbing = true;
}
}
void OnCollisionExit(Collision collision)
{
if (collision.gameObject.CompareTag("Climbable"))
{
isClimbing = false;
}
}
}
```
以上代码实现了3D人物的移动、跳跃、奔跑、贴墙跑和边缘攀爬功能。其中,`moveSpeed`变量控制人物移动速度,`jumpForce`变量控制跳跃力度。在`Update`函数中,根据按键输入控制人物的移动和跳跃。通过`OnCollisionEnter`和`OnCollisionExit`函数判断人物是否在地面上或者贴着爬升的物体。在按住左Shift键时,人物会奔跑;按住左Ctrl键时,人物会贴墙跑。按下E键时,人物可以边缘攀爬。
