您如何在Godot中制作类似MMO的技能快捷栏？

问题描述

我想在MMO或MOBA游戏中创建一个“快捷键”，通过按键来激活技能。

我找到了一个gdscript教程，但它使用点击而不是按键。我尝试更改代码以检查何时用housing = fetch_california_housing() X_train_full,X_test,y_train_full,y_test = train_test_split(housing.data,housing.target,random_state=42) X_train,X_valid,y_train,y_valid = train_test_split(X_train_full,random_state=42) scaler = StandardScaler() X_train = scaler.fit_transform(X_train) X_valid = scaler.transform(X_valid) X_test = scaler.transform(X_test) input_A = keras.layers.Input(shape=[5],name="wide_input") input_B = keras.layers.Input(shape=[6],name="deep_input") hidden1 = keras.layers.Dense(30,activation="relu")(input_B) hidden2 = keras.layers.Dense(30,activation="relu")(hidden1) concat = keras.layers.concatenate([input_A,hidden2]) output = keras.layers.Dense(1,name="output")(concat) model = keras.models.Model(inputs=[input_A,input_B],outputs=[output]) model.compile(loss='mse',optimizer=keras.optimizers.SGD(lr=1e-3)) X_train_A,X_train_B = X_train[:,:5],X_train[:,2:] X_valid_A,X_valid_B = X_valid[:,X_valid[:,2:] X_test_A,X_test_B = X_test[:,X_test[:,2:] X_new_A,X_new_B = X_test_A[:3],X_test_B[:3] history = model.fit((X_train_A,X_train_B),epochs=20,validation_data=((X_valid_A,X_valid_B),y_valid)) mse_test = model.evaluate((X_test_A,X_test_B),y_test) y_pred = model.predict((X_new_A,X_new_B))按下“ K”，但这没用。

这是错误：

if Input.is_key_pressed(KEY_K):

我是新手，不知道如何解决该错误。

以下是该教程的链接：https://kidscancode.org/godot_recipes/ui/cooldown_button/

这是原始代码：

E 0:00:40.192   emit_signal: Error calling method from signal 'pressed': 'TextureButton(AbilityButton.gd)::_on_key_pressed':
Method expected 1 arguments,but called with 0..<C++ Source>  core/object.cpp:1228 @ emit_signal()

这是我的代码：

extends TextureButton

onready var time_label = $Counter/Value

export var cooldown = 1.0


func _ready():
    print_tree_pretty()
    time_label.hide()
    $Sweep.value = 0
    $Sweep.texture_progress = texture_normal
    $Timer.wait_time = cooldown
    set_process(false)


func _process(delta):
    time_label.text = "%3.1f" % $Timer.time_left
    $Sweep.value = int(($Timer.time_left / cooldown) * 100)


func _on_Timer_timeout():
    print("ability ready")
    $Sweep.value = 0
    disabled = false
    time_label.hide()
    set_process(false)


func _on_AbilityButton_pressed():
    disabled = true
    set_process(true)
    $Timer.start()
    time_label.show()


func _on_key_pressed():
    pass

解决方法

错误消息说明了一切：Method expected 1 arguments,but called with 0。

这意味着绑定到信号的方法是用一个参数定义的，但是信号发送0个参数并且引擎会大喊。

您可以在BaseButton文档中检查信号发送的自变量（0）。

尝试删除event：

func _on_key_pressed(event): → func _on_key_pressed():

祝你好运！
