Creating the player scene

With the project settings in place, we can start working on the player-controlled character. Player 对象. 单独创建Player场景的好处之一是, 在游戏的其他部分做出来之前, 我们就可以对其进行单独测试.

节点结构

是什么. 单击 “其他节点” 按钮并将 Area2D 节点添加到场景中. Godot将在场景树中的节点旁边显示警告图标. 你现在可以忽略它. 我们稍后再谈. Area2D 可以检测到与玩家重叠或进入玩家内的物体. 通过双击节点名称将其名称更改为 Player. 我们已经设置好了场景的根节点, 现在可以向该角色中添加其他节点来增加功能. Player 节点之前, 我们要确保不会通过点击它们而意外地移动它们或调整其大小. 选择节点, 然后点击锁右侧的图标；它的工具提示显示 确保对象的子级不可选择. 保存场景。点击场景 -> 保存，或者在 Windows/Linux 平台上按下 Ctrl+S，在 macOS 上按下 Cmd+S。 注解 对于此项目, 我们将遵循Godot的命名约定.

• GDScript : 类(节点)使用大驼峰命名法(PascalCase), 变量和函数使用蛇形命名法(snake_case), 常量使用全大写(ALL_CAPS)(请参阅 GDScript 风格指南).
• C#: Classes, export variables and methods use PascalCase, private fields use _camelCase, local variables and parameters use camelCase (See C# 风格指南). Be careful to type the method names precisely when connecting signals.

  精灵动画

  Player node and add an AnimatedSprite2D node as a child. The AnimatedSprite will handle the appearance and animations for our player. Notice that there is a warning symbol next to the node. An AnimatedSprite2D requires a SpriteFrames resource, which is a list of the animations it can display. To create one, find the Frames property in the Inspector and click “[empty]“ -> “New SpriteFrames”. Click again to open the “SpriteFrames” panel: art 文件夹中. 将每个动画的两张图像, playerGrey_up[1/2] 和 playerGrey_walk[1/2] , 拖到对应动画的面板的 “动画帧” 处: AnimatedSprite2D node and set the Scale property to (0.5, 0.5). You can find it in the Inspector under the Node2D heading. CollisionShape2D as a child of Player. This will determine the player’s “hitbox”, or the bounds of its collision area. For this character, a CapsuleShape2D node gives the best fit, so next to “Shape” in the Inspector, click “[empty]“” -> “New CapsuleShape2D”. Using the two size handles, resize the shape to cover the sprite: Player 场景看起来应该像这样: 修改完成后请确保再次保存场景. In the next part, we’ll add a script to the player node to move and animate it. Then, we’ll set up collision detection to know when the player got hit by something.
