实现物体绕不同轴旋转 并调用外部函数unity3d插件 (2).doc

实现物体绕不同轴旋转 并调用外部函数第一个和第二脚本赋给目标物体；第三个脚本赋给任何一个物体作为测试物体使用。代码目的是方便外部调用和函数重用。注意isRotating参数的使用。第一个文件，声明枚举类型，分别为均匀变化和加速变化using UnityEngine;using System.Collections;public enum CTRotationTypeUniform,AccelerateUniformly第二个文件：主函数，实现围绕轴变化的两个函数，分别为均匀变化和加速变化using UnityEngine;using System.Collections;public class CTRotation : MonoBehaviour / Use this for initializationvoid Start () / Update is called once per framevoid Update () if (isRotating)executeRotate();bool isRotating = false;Quaternion definedRotation = new Quaternion(0, 0, 0,0);Vector3 rotateVector = new Vector3(1,0,0);float rotateVelocity = 0;float accelerateDuration = 0;float leftDuration = 0;float rotateDuration = 0;int rotateAxis = 0;float angleRange = 0;float deltaRotate = 0;/0;/ acceleration when it is in the accelerating process.float rotateAcceleration = 0;CTRotationType rotateType;/int RotateType = 0;private void initRotateArgument( float _initAngleRange, int _initRotateAxis, float _initRotateDuration)rotateAxis = _initRotateAxis;rotateDuration = _initRotateDuration;leftDuration = _initRotateDuration;angleRange = _initAngleRange;rotateType = CTRotationType.Uniform;public void RotateTo(float _angleRange, int _axis, float _duration)print(“in the rotateto”);isRotating = false;rotateType = CTRotationType.Uniform;/RotateType = 0;initRotateArgument(_angleRange, _axis, _duration);switch(rotateAxis)case 0: /rotate around X axisrotateVector = Vector3.right;break;case 1:/rotate around Y axisrotateVector = Vector3.up;break;case 2:/rotate around Z axisrotateVector = Vector3.forward;break;default:break;deltaRotate = angleRange/rotateDuration;isRotating = true;public void RotateTo(float _angleRange, int _axis, float _duration, float _accelerateDuration)isRotating = false;rotateType = CTRotationType.AccelerateUniformly;/RotateType = 1;rotateAcceleration = 1/(rotateDuration - accelerateDuration)*accelerateDuration);initRotateArgument(_angleRange, _axis, _duration);switch(rotateAxis)case 0: /rotate around X axisrotateVector = Vector3.right;break;case 1:/rotate around Y axisrotateVector = Vector3.up;break;case 2:/rotate around Z axisrotateVector = Vector3.forward;break;default:break;accelerateDuration = _accelerateDuration;/ deltaRotate = angleRange/(_duration - _accelerateDuration*2);isRotating = true;void executeRotate()switch (rotateType)/case 0:/CTMoveType.Uniform:case CTRotationType.Uniform:uniformRotate();break;/case 1:/CTMoveType.AccelerateUniformly:case CTRotationType.AccelerateUniformly:accelerateRotate();break;leftDuration -= Time.deltaTime;/* if (leftDuration (rotateDuration - accelerateDuration)rotateVelocity = (float)(angleRange*(rotateDuration - leftDuration)*rotateAcceleration);/ transform.Rotate(rotateVelocity * Time.deltaTime*rotateVector, Space.World);transform.Rotate(rotateVelocity * rotateVector*Time.deltaTime, Space.World);else if (leftDuration accelerateDuration)rotateVelocity = (float)(angleRange*accelerateDuration)*rotateAcceleration);transform.Rotate(rotateVelocity*rotateVector*Time.deltaTime, Space.World);else if (leftDuration 0)rotateVelocity= (float)(angleRange*leftDuration)*rotateAcceleration);transform.Rotate(rotateVelocity*rotateVector*Time.deltaTime, Space.World);elseisRotating = false;private void uniformRotate()print(leftDuration);/if(leftDuration)if(leftDuration 0)transform.Rotate(rotateVector*deltaRo
