Godot 4. 为什么我的 if 条件没有完成所有过程就结束了

  • 772

我遇到了一个问题，我的 if 条件起作用了，但是很快就结束了她的功能。

var speed = 75
var dir: Vector2 = Vector2.ZERO
var enter: bool = false

@onready var camera = $"../camera"

func _ready():
    randomize()
    _choose_random_direction()

func _physics_process(delta: float) -> void:
    
    velocity = dir * speed
    
    if Input.is_action_just_pressed("accept"):
        camera.unzoomi(delta)
    
    move_and_slide()

func _choose_random_direction():
    var directions = [
        Vector2(-1, 0), Vector2(1, 0),  # Left, Right
        Vector2(0, -1), Vector2(0, 1),  # Up, Down
        Vector2(-1, -1), Vector2(1, -1),  # Top-left, Top-right
        Vector2(-1, 1), Vector2(1, 1),   # Bottom-left, Bottom-right
        Vector2(0, 0)
        ]
    dir = directions[randi() % directions.size()]
    await get_tree().create_timer(randf_range(1, 3)).timeout
    _choose_random_direction()

func _physics_process 中的 if 假设是相机的缩放具有平滑过渡，但是当我调用缩放功能时，缩放在一个实例中结束，而不是我编程的 2 秒。

这是相机的代码：

var zooming: bool = false

@onready var player = $"../player"

func _process(delta: float) -> void:
    position = player.position

func zoomi(delta):
    var end: float = 3
    
    zooming = true
    
    if zooming == true:
        zoom.x = lerp(zoom.x, end, 0.4 * delta)
        zoom.y = lerp(zoom.y, end, 0.4 * delta)

    if zoom.x > end * .8:
        zooming = false

func unzoomi(delta):
    var end: float = 3
    
    zooming = true
    
    if zooming == true:
        zoom.x = lerp(zoom.x, end, 0.4 * delta)
        zoom.y = lerp(zoom.y, end, 0.4 * delta)

    if zoom.x > end * .8:
        zooming = false

谢谢。

    zoomi()您的问题是，在和函数中，缩放过渡unzoomi()仅在调用该函数时发生一次。由于lerp()需要多个帧才能创建平滑过渡，因此您需要在 中不断更新缩放_process()。

    这是相机的代码：

    var zooming: bool = false
var zoom_target: float = 1.0  
var zoom_speed: float = 0.4  

@onready var player: CharacterBody2D = $"../player"

func _process(delta: float) -> void:
    position = player.position
    if zooming:
        zoom.x = lerp(zoom.x, zoom_target, zoom_speed * delta)
        zoom.y = lerp(zoom.y, zoom_target, zoom_speed * delta)
        if abs(zoom.x - zoom_target) < 0.05:
            zooming = false

func zoomi():
    zoom_target = 3.0 
    zooming = true

func unzoomi():
    zoom_target = 1.0
    zooming = true

    这是播放器的代码：

    var speed = 75
var dir: Vector2 = Vector2.ZERO
var enter: bool = false

@onready var camera: Camera2D = $"../camera"

func _ready():
    randomize()
    _choose_random_direction()

func _physics_process(delta: float) -> void:
    
    velocity = dir * speed
    if Input.is_action_just_pressed("zoom_in"):
        camera.zoomi()
    elif Input.is_action_just_pressed("zoom_out"):
        camera.unzoomi()
    
    move_and_slide()

func _choose_random_direction():
    var directions = [
        Vector2(-1, 0), Vector2(1, 0),  # Left, Right
        Vector2(0, -1), Vector2(0, 1),  # Up, Down
        Vector2(-1, -1), Vector2(1, -1),  # Top-left, Top-right
        Vector2(-1, 1), Vector2(1, 1),   # Bottom-left, Bottom-right
        Vector2(0, 0)
        ]
    dir = directions[randi() % directions.size()]
    await get_tree().create_timer(randf_range(1, 3)).timeout
    _choose_random_direction()
