项目设置事件
您可以在下面设置输入地图 项目> 项目设置 > 输入映射 然后这样做：
每一帧判断事件
代码语言：javascript复制# polling - runs every frame
func _physics_process(delta):
if Input.is_action_pressed("ui_right"):
# move as long as the key/button is pressed
position.x = speed * delta按键事件回调触发
代码语言：javascript复制# input event - runs when the input happens
func _input(event):
if event.is_action_pressed("jump"):
jump()按键事件
代码语言：javascript复制func _unhandled_input(event):
if event is InputEventKey:
if event.pressed and event.keycode == KEY_J:
AudioManager.play("pistol")
if event.pressed and event.keycode == KEY_K:
AudioManager.play("laser_gun")鼠标事件
鼠标按钮
代码语言：javascript复制func _input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
print("Left button was clicked at ", event.position)
if event.button_index == BUTTON_WHEEL_UP and event.pressed:
print("Wheel up")鼠标移动
下面是一个使用鼠标事件拖放 Sprite 节点：
代码语言：javascript复制extends Node
var dragging = false
var click_radius = 32 # Size of the sprite
func _input(event):
if event is InputEventMouseButton and event.button_index == BUTTON_LEFT:
if (event.position - $Sprite.position).length() < click_radius:
# Start dragging if the click is on the sprite.
if !dragging and event.pressed:
dragging = true
# Stop dragging if the button is released.
if dragging and !event.pressed:
dragging = false
if event is InputEventMouseMotion and dragging:
# While dragging, move the sprite with the mouse.
$Sprite.position = event.position视区显示坐标
使用节点中的函数获取鼠标坐标和视区大小，例如：
代码语言：javascript复制func _input(event):
# Mouse in viewport coordinates
if event is InputEventMouseButton:
print("Mouse Click/Unclick at: ", event.position)
elif event is InputEventMouseMotion:
print("Mouse Motion at: ", event.position)
# Print the size of the viewport
print("Viewport Resolution is: ", get_viewport_rect().size)或者，可以向视区询问鼠标位置：
代码语言：javascript复制get_viewport().get_mouse_position()设置鼠标光标
代码语言：javascript复制extends Node
# Load the custom images for the mouse cursor.
var arrow = load("res://arrow.png")
var beam = load("res://beam.png")
func _ready():
# Changes only the arrow shape of the cursor.
# This is similar to changing it in the project settings.
Input.set_custom_mouse_cursor(arrow)
# Changes a specific shape of the cursor (here, the I-beam shape).
Input.set_custom_mouse_cursor(beam, Input.CURSOR_IBEAM)
