[Godot] C#简单实现人物俯视视角的控制和动画

实现效果

场景搭建

本文章只分享了关于移动和动画的，没有给碰撞体，大家根据需要自行添加吧

相机的缩放大小可以根据自己的需要调整

我的人物动画结构是这样的，待机动（ idle ）}和移动动画（ walk ）

脚本实现

移动

首先，我们需要声明一个移动速度变量，然后将移动代码写在Process函数中

using Godot;
using System;
 
public partial class Player : CharacterBody2D
{
    [Export] public float moveSpeed;
 
    public override void _Process(double delta)
    {
        Move((float)delta);
    }
 
    void Move(float delta)
    {
        Vector2 direction = Vector2.Zero;
 
        if (Input.IsActionPressed("right"))
            direction.X += 1;
        if (Input.IsActionPressed("left"))
            direction.X -= 1;
        if (Input.IsActionPressed("down"))
            direction.Y += 1;
        if (Input.IsActionPressed("up"))
            direction.Y -= 1;
 
        direction = direction.Normalized();
        Velocity = direction * moveSpeed;
        MoveAndSlide(); //根据速度滑动式移动角色，并自动处理碰撞
    }
 
}

构建场景，在人物面板设置变量值，然后在面板里面添加按键映射，我们可以就能正常的移动人物了

动画

接下来是动画部分，我用枚举实现了一个简单的状态机，并且在移动代码里面添加了水平翻转的代码

using Godot;
using System;
 
public partial class Player : CharacterBody2D
{
    private enum AnimState
    {
        idle,
        walk
    }
    AnimState animState = AnimState.idle;
 
    private AnimatedSprite2D _playerAnim;
 
    public override void _Ready()
    {
        _playerAnim = GetNode<AnimatedSprite2D>("./AnimatedSprite2D");
    }
 
    public override void _Process(double delta)
    {
        Move((float)delta);
 
        AnimStateSwitch();
    }
 
    void Move(float delta)
    {
        ...
 
        if (direction != Vector2.Zero)
        {
            ...
 
            if (direction.X > 0) _playerAnim.FlipH = false;
            else if (direction.X < 0) _playerAnim.FlipH = true;
        }
        else
        {
            animState = AnimState.idle;
        }
    }
 
    void AnimStateSwitch()
    {
        switch (animState)
        {
            case AnimState.idle: _playerAnim.Play("idle"); break;
            case AnimState.walk: _playerAnim.Play("walk"); break;
        }
    }
}

构建并运行场景，我们就能丝滑的控制人物的动画了

完整脚本

using Godot;
using System;
 
public partial class Player : CharacterBody2D
{
    [Export] public float moveSpeed;
 
    private enum AnimState
    {
        idle,
        walk
    }
    AnimState animState = AnimState.idle;
 
    private AnimatedSprite2D _playerAnim;
 
    public override void _Ready()
    {
        _playerAnim = GetNode<AnimatedSprite2D>("./AnimatedSprite2D");
    }
 
    public override void _Process(double delta)
    {
        Move((float)delta);
 
        AnimStateSwitch();
    }
 
    void Move(float delta)
    {
        Vector2 direction = Vector2.Zero;
 
        if (Input.IsActionPressed("right"))
            direction.X += 1;
        if (Input.IsActionPressed("left"))
            direction.X -= 1;
        if (Input.IsActionPressed("down"))
            direction.Y += 1;
        if (Input.IsActionPressed("up"))
            direction.Y -= 1;
 
        direction = direction.Normalized();
        if (direction != Vector2.Zero)
        {
            Velocity = direction * moveSpeed;
            animState = AnimState.walk;
            MoveAndSlide();
 
            if (direction.X > 0) _playerAnim.FlipH = false;
            else if (direction.X < 0) _playerAnim.FlipH = true;
        }
        else
        {
            animState = AnimState.idle;
        }
    }
 
    void AnimStateSwitch()
    {
        switch (animState)
        {
            case AnimState.idle: _playerAnim.Play("idle"); break;
            case AnimState.walk: _playerAnim.Play("walk"); break;
        }
    }
}

相机跟随

关于相机的平滑跟随，我们有一个简单的办法，设置 Position Smoothing 属性 Enabled 为 True 即可平滑跟随，可以设置 speed 来控制跟随的速度

总结

这里简单的跟大家分享了一下基础的控制人物方法，大家可以根据需要自行调整
