前言
Godot 官方 教程
Godot 2d 官方案例C#重构 专栏
Godot 2d 重构 github地址
实现效果
难点介绍
Godot GDScript和C# 对应关系大部分靠猜
文件导入
- 资源地址：默认为res://开头
- 2D贴图导入类型：Texture2D
public Texture2D Bullet_Image = new Texture2D();
Bullet_Image = GD.Load<Texture2D>("res://bullet.png");
2D属性赋值，PhysicsServer
PhysicsServer 用于给赋值属性和属性初始化
Shape = PhysicsServer2D.CircleShapeCreate();
PhysicsServer2D.ShapeSetData(Shape,8);
刷新UI
在_Process里面调用QueueRedraw
public override void _Process(double delta)
{QueueRedraw();
}
绘制UI
生成2D贴图
DrawTexture(Texture2D img, Vector2 position);
重载_Draw函数
public override void _Draw(){var offset = -Bullet_Image.GetSize();//Godot重载了对应的运算符offset = offset /2;foreach (var item in bullets){DrawTexture(Bullet_Image, item.position + offset);}base._Draw();}
离开页面销毁
销毁
PhysicsServer2D.FreeRid(item.body);
离开页面销毁
public override void _ExitTree(){foreach (var item in bullets){PhysicsServer2D.FreeRid(item.body);}PhysicsServer2D.FreeRid(Shape);base._ExitTree();}
定位到鼠标位置
重载 _Input函数，获取鼠标参数
public override void _Input(InputEvent @event)
{if(@event is InputEventMouseMotion){var mouseEvent = (@event as InputEventMouseMotion);Position = mouseEvent.Position;}base._Input(@event);
}
