Unity3D 学习笔记 增加跳跃

补充按键 public string keyJump = “space”;
检测按键的下降沿
jump = Input.GetKeyDown(keyJump);
或者

加入Jump动画，transition条件为trigger的Jump
在动画控制脚本中
if(pi.jump)
{
anim.SetTrigger(“Jump”);
thrust = new Vector3(0,JumpFactor,0);
}
void FixedUpdate()
{
rigid.velocity = new Vector3(bodyVelocity.x,rigid.velocity.y,bodyVelocity.z) + thrust;
thrust = Vector3.zero;
}
加入跳跃控制脚本
但是空中需要按键保持速度，如果要修正为空中时不受方向控制并能保持惯性还需要其他操作。
先添加是否落地的判断。
给plane的layer设定为Ground

创建状态机进入脚本和退出脚本FSMENTER FSMEXIT
public class FSMOnEnter : StateMachineBehaviour
{
public string[] onEnterMessage;
override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
foreach(var msg in onEnterMessage)
{
animator.gameObject.SendMessageUpwards(msg);
}
}
}

在胶囊添加OnGroundSensor脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class OnGroundSensor : MonoBehaviour
{
public CapsuleCollider cap;
public float offset = 0.1f;
private Vector3 point1;
private Vector3 point2;
private float radius;
// Start is called before the first frame update
void Start()
{
radius = cap.radius - 0.05f;
}
// Update is called once per frame
void FixedUpdate()
{
//顶点1，位置加上up方向上长度radius
point1 = transform.position + transform.up * (radius - offset);
point2 = transform.position + transform.up * (cap.height - offset);
Collider[] outputCols = Physics.OverlapCapsule(point1,point2,radius,LayerMask.GetMask(“Ground”));
if (outputCols.Length != 0)
{
SendMessageUpwards(“IsOnGround”);
}
else
{
SendMessageUpwards(“IsNotOnGround”);
}
}
}
在ActorController里添加对应函数
public void IsOnGround()
{
print(“IsOnGround”);
}
public void IsNotOnGround()
{
print(“IsNotOnGround”);
}

正确显示是否在ground上

添加falling动画

添加OnGround的bool条件
设置好状态机循环哪个需要OnGround哪个不需要
在函数中添加对应的bool设置
public void IsOnGround()
{
print(“IsOnGround”);
anim.SetBool(“OnGround”,true);
}
public void IsNotOnGround()
{
print(“IsNotOnGround”);
anim.SetBool(“OnGround”,false);
}
接下来添加空中的惯性以及控制禁止操控
playerinput中添加
public bool inputEnable;

只有使能时才能计算
public void OnGround()
{
print(“On Ground”);
pi.inputEnable = true;
}
public void ExitGround()
{
print(“Exit Ground”);
pi.inputEnable = false;
}
添加inputenable的赋值
运行游戏，可以正常工作
