如何实现玩家攻击时仅小幅移动，非攻击时正常移动？

核心问题分析 #

1. 攻击状态切换逻辑错误：attack()函数中仅在一帧内就将状态切回MOVE，导致攻击状态根本无法持续，玩家自然能正常移动。
2. 攻击状态未处理移动逻辑：原代码在攻击时直接跳过物理更新，既没实现小幅移动，也导致状态管理失效。
3. 输入拼写错误：Input.get_vector中的"rihgt"应为"right"，会导致右方向输入无效。

修改后的完整代码 #

extends CharacterBody2D

@export var speed: float = 100
@export var accel: float = 10
@export var attack_speed: float = 30  # 攻击时的小幅移动速度

@export var dashing = false
@export var dashdistance: float = 300

@export var attacking = false
@export var attackdistance: float = 100

@export var dasheffect = preload("res://dasheffect.tscn")
@onready var anime = $AnimatedSprite2D

@onready var sword: Node2D = get_node("sword")
@onready var sword_anime: AnimationPlayer = get_node("sword/SwordAnimationPlayer")

enum States {
    MOVE,
    ATTACK
}

var state = States.MOVE


func _process(_delta: float) -> void:
    var mouse_direction: Vector2 = (get_global_mouse_position() - global_position).normalized()
    
    sword.rotation = mouse_direction.angle()
    
    if mouse_direction.x > 0 and anime.flip_h:
        anime.flip_h = false
    elif mouse_direction.x < 0 and not anime.flip_h: 
        anime.flip_h = true


func _physics_process(delta):
    match state:
        States.MOVE:
            move(delta)
        States.ATTACK:
            attack_move(delta)  # 攻击状态下处理小幅移动


func move(delta):
    var direction: Vector2 = Input.get_vector("left", "right", "up", "down")  # 修复拼写错误
    
    velocity.x = move_toward(velocity.x, speed * direction.x, accel)
    velocity.y = move_toward(velocity.y, speed * direction.y, accel)
    
    if velocity != Vector2.ZERO:
        anime.play("run")
    else:
        anime.play("idle")
    
    dash()
    move_and_slide()
    
    if Input.is_action_just_pressed("attack"):
        state = States.ATTACK
        attacking = true
        sword_anime.play("swing")
        anime.play("attack")


func attack_move(delta):
    # 攻击状态下允许小幅移动
    var direction: Vector2 = Input.get_vector("left", "right", "up", "down")
    
    velocity.x = move_toward(velocity.x, attack_speed * direction.x, accel)
    velocity.y = move_toward(velocity.y, attack_speed * direction.y, accel)
    
    move_and_slide()
    
    # 等待攻击动画结束后切回移动状态
    if sword_anime.is_playing() == false:
        state = States.MOVE
        attacking = false


func dash():
    var mouse_direction: Vector2 = (get_global_mouse_position() - global_position).normalized()
    
    if Input.is_action_just_pressed("ui_accept"):
        velocity = mouse_direction.normalized() * dashdistance
        dashing = true
        await get_tree().create_timer(0.2)
        dashing = false

关键修改点 #

• 新增attack_speed变量控制攻击时的移动速度，实现小幅移动效果。
• 重构攻击状态逻辑：将攻击动画播放和状态切换分离，通过监听动画是否结束来切回移动状态，确保攻击过程持续。
• 修复方向输入的拼写错误，保证右方向键正常工作。
• 在_physics_process中根据状态分别处理移动或攻击移动，不再提前return跳过物理更新。
