Question

volumes:
      # this is needed to communicate with the postgres and redis services
      - ./superset_config.py:/home/superset/superset/superset_config.py
      # this is needed for development, remove with SUPERSET_ENV=production
      - ../../superset:/home/superset/superset

*下面的代码是我尝试计算跳转次数的地方，以防止它们超过两次跳转。我的目标是创造一个双重跳跃，因此我使用了小于运算符来控制该数字* 如果jump_pressed：如果jump_count <2： jump_count + = 1 跳（）接地=假<-我不得不在下面再次复制粘贴此代码，因此我的问题没有出现错误。

# changed switch statement setup by creating a new variable and using "." operator

extends Node2D

const FLOOR = Vector2(0,-1)
const GRAVITY = 5
const DESCEND = 0.6
var speed = 100
var jump_height = -250
var motion = Vector2()

var jump_count = 0
var currentState = PlayerStates.STATE_RUNNING
var grounded = false

enum PlayerStates {STATE_RUNNING, STATE_JUMPING, STATE_DOUBLE_JUMPING, STATE_GLIDING}

func _ready():
    var currentState = PlayerStates.STATE_RUNNING
    pass

func jump():
    motion.y = jump_height

func glide():
    if motion.y < 500:
        motion.y += DESCEND

func _process(delta):
    var jump_pressed = Input.is_action_pressed('jump')
    var glide_pressed = Input.is_action_pressed('glide')

首先，我想如果您想使用KinematicBody2D，则需要使用_physics_process并在move_and_slide中执行逻辑，除此之外，您的代码几乎可以正常工作：

extends KinematicBody2D

const FLOOR = Vector2(0,-1)
const GRAVITY = 3000
const DESCEND = 0.6

var speed = 100
var jump_height = 250
var motion = Vector2()

var jump_count = 0

func jump():
    motion.y = -jump_height

func glide():
    if motion.y < 500:
        motion.y += DESCEND

func _physics_process(delta):
    var jump_pressed = Input.is_action_pressed('jump')
    var glide_pressed = Input.is_action_pressed('glide')

    motion.y += delta * GRAVITY
    var target_speed = Vector2(speed, motion.y)

   if is_on_floor():
       jump_count = 0
       if glide_pressed:
           glide()        

    if jump_pressed and jump_count < 2:
        jump_count += 1
        jump()

    motion = lerp(motion, target_speed, 0.1)
    motion = move_and_slide(motion, FLOOR)

您还需要在Godot编辑器中将节点类型更改为KinematicBody2D（右键单击该节点，然后单击更改类型）。

如何编写控制跳转并创建两次跳转动作的代码？
