跳跃状态检测与RootMotion跳跃
添加跳跃状态。
public
enum
PlayerState
{
Idle
,
Move
,
Jump
}
添加跳跃的转换逻辑。
//PlayerController
public
void
ChangeState
(
PlayerState
playerState
)
{
switch
(
playerState
)
{
case
PlayerState
.
Idle
:
stateMachine
.
ChangeState
<
PlayerIdleState
>
(
)
;
break
;
case
PlayerState
.
Move
:
stateMachine
.
ChangeState
<
PlayerMoveState
>
(
)
;
break
;
case
PlayerState
.
Jump
:
stateMachine
.
ChangeState
<
PlayerJumpState
>
(
)
;
break
;
default
:
break
;
}
}
创建PlayerJumpState。
public
class
PlayerJumpState
:
PlayerStateBase
{
public
override
void
Enter
(
)
{
player
.
PlayAnimation
(
"Jump"
)
;
player
.
PlayerModel
.
SetRootMotionAction
(
OnRootMotion
)
;
}
public
override
void
Update
(
)
{
//第一次执行Update时，也许当前动画还不是Jump
//确定当前是播放Jump动画
AnimatorStateInfo
stateInfo
=
player
.
PlayerModel
.
Animator
.
GetCurrentAnimatorStateInfo
(
0
)
;
if
(
stateInfo
.
IsName
(
"Jump"
)
)
{
//获取动画的进度
float
animationTime
=
stateInfo
.
normalizedTime
;
if
(
animationTime
>
0.1f
&&
animationTime
<
0.6f
)
{
}
else
if
(
animationTime
>=
0.9f
)
{
player
.
ChangeState
(
PlayerState
.
Idle
)
;
return
;
}
}
}
public
override
void
Exit
(
)
{
player
.
PlayerModel
.
ClearRootMotion
(
)
;
}
public
void
OnRootMotion
(
Vector3
deltaPosition
,
Quaternion
deltaRotation
)
{
player
.
CharacterController
.
Move
(
deltaPosition
)
;
}
}
-
在进入跳跃状态时播放跳跃状态，并将跳跃的RootMotion逻辑(和移动是一样的)传递给PlayerModel的RootMotionAction执行。
-
在跳跃动画播放进度10%~60%时允许移动等其他逻辑，注意判断当前动画是否为跳跃动画，进入跳跃状态后，还有可能处于动画切换的过程。
-
在跳跃动画播放进度超过90%时，切换回Idle状态。
-
退出时清空RootMotionAction。
//检测玩家跳跃
if
(
Input
.
GetKeyDown
(
KeyCode
.
Space
)
)
{
player
.
ChangeState
(
PlayerState
.
Jump
)
;
return
;
}
分别给PlayerMoveState，和PlayerIdleState添加跳跃状态的检测。
空中位移和旋转
首先设置空中跳跃的高度，给RootMotion位移乘一个系数。
public
void
OnRootMotion
(
Vector3
deltaPosition
,
Quaternion
deltaRotation
)
{
deltaPosition
.
y
*=
player
.
jumpForce
;
player
.
CharacterController
.
Move
(
deltaPosition
)
;
}
对应添加跳跃力和空中位移速度的配置量。
//PlayerController

public
float
gravity
=

9.8f
;
public
float
rotateSpeed

public
float

1f

public
float
jumpForce
=

float
moveSpeedForJump

给跳跃进度10%~60%之前添加位移旋转逻辑，类似移动控制，并由配置量控制位移速度。
public
override
void
Update
(
)
{
//第一次执行Update时，也许当前动画还不是Jump
//确定当前是播放Jump动画
AnimatorStateInfo
stateInfo
=
player
.
PlayerModel
.
Animator
.
GetCurrentAnimatorStateInfo
(
0
)
;
if
(
stateInfo
.
IsName
(
"Jump"
)
)
{
//获取动画的进度
float
animationTime
=
stateInfo
.
normalizedTime
;
if
(
animationTime
>
0.1f
&&
animationTime
<
0.6f
)
{
//处理空中位移
float
h
=
Input
.
GetAxis
(
"Horizontal"
)
;
float
v
=
Input
.
GetAxis
(
"Vertical"
)
;
Vector3
input
=
new
Vector3
(
h
,
0
,
v
)
;
if
(
h
!=
0
||
v
!=
0
)
{
//处理旋转
//获取相机的旋转值y
float
y
=
Camera
.
main
.
transform
.
rotation
.
eulerAngles
.
y
;
//让四元数和向量相乘，表示这个向量按照这个四元数所表达的角度进行旋转后得到的向量

targetDir
=
Quaternion
.
Euler
(

,
y
,

)
*
input
;
//Slerp插值
player
.
PlayerModel

transform
.
rotation
=
Quaternion
.
Slerp
(
player

.
rotation
,
Quaternion
.
LookRotation
(

)
,
Time
.
deltaTime
*

.
rotateSpeed
)
;
}
Vector3
dir
=
Camera
.
main
.
transform
.
TransformDirection
(
input
)
;
//Vector3 dir2 = Quaternion.Euler(0, Camera.main.transform.rotation.eulerAngles.y, 0) * new Vector3(h, 0, v);
//player.CharacterController.Move();
player
.
CharacterController
.
Move
(
player
.
moveSpeedForJump
*
Time
.
deltaTime
*
dir
)
;
}
else
if
(
animationTime
>=
0.9f
)
{
player
.
ChangeState
(
PlayerState
.
Idle
)
;
return
;
}
}
}
最终效果如下，实现跳跃，位移以及空中转向。
