本文章给大家分享一下如何实现基本的移动和进阶的跳跃（跳跃缓冲、可变跳跃、土狼时间）以及相对应的重力代码，大家可以根据自己的需要自行修改
实现效果
场景搭建
因为Godot不像Unity，一个节点只能绑定一个脚本，所以我们可以创建一个节点，用来存放绑定各种脚本，这样能大大规范化我们的代码，毕竟一个脚本写几千行代码相信大家也不想经历（本人曾经深受其害）
有一点，玩家的碰撞体最好用胶囊或者其他的边角圆润的形状，否则我们直接绑的一个方块，会导致跳跃到平台边缘根本上不去
其中的RayCast2D节点是我用来判断玩家顶头的，大家可以根据需要调整，下面我给大家分享一下代码
代码
Player
using Godot;
using System;public partial class Player : CharacterBody2D
{[ExportCategory("Item")][Export] public float _moveSpeed; // 玩家移动速度[Export] public float _jumpForce; // 跳跃初始力度（用于起跳）[Export] public float _jumpCumulative; // 可变跳跃额外加速度（持续跳跃时叠加）[Export] public float _downSpeed; // 快速下落的速度（按下下落键时使用）[Export] public float _gravity; // 重力加速度（用于下落）[ExportGroup("Time")][Export] public float _jumpBufferTime; // 跳跃缓冲时间（提前按跳跃键后多长时间内仍有效）[Export] public float _jumpCumulativeTime; // 跳跃蓄力时间（可变跳跃持续多久）[Export] public float _coyoteTime; // 土狼时间（离地后多久内仍可跳跃）[ExportGroup("Node")][Export] public RayCast2D RayHead; // 检测头顶碰撞的射线（用于防止跳跃时顶头）public override void _PhysicsProcess(double delta){MoveAndSlide(); // 移动函数（实际处理碰撞和滑动）}
}
PlayerMove
using Godot;
using System;public partial class PlayerMove : Node2D
{private Player player; // 引用 Player 脚本，用于访问属性和控制玩家public override void _Ready(){// 获取 Player 脚本（父节点 -> 父节点 -> Player）player = GetParent().GetParent<Player>();}public override void _PhysicsProcess(double delta){Move(); // 每帧执行移动逻辑}private void Move(){float directionX = 0f; // 水平方向，右为 +1，左为 -1if (Input.IsActionPressed("Right")){directionX += 1f;}if (Input.IsActionPressed("Left")){directionX -= 1f;}// 设置玩家水平速度，垂直方向保持不变player.Velocity = new Vector2(directionX * player._moveSpeed, player.Velocity.Y);}
}
PlayerJump
using Godot;
using System;public partial class PlayerJump : Node2D
{private Player player;// 跳跃数值参数private float _jumpForce; // 跳跃初始力度private float _jumpCumulative; // 可变跳跃额外力度private float _downSpeed; // 下坠加速度private float _gravity; // 重力值// 时间控制参数private float _jumpBufferTime; // 跳跃缓冲持续时间private float _jumpCumulativeTime; // 可变跳跃持续时间private float _coyoteTime; // 土狼时间（离地后仍可跳的时间）// 跳跃状态计时器private float _jumpBufferTimer; // 当前跳跃缓冲计时private float _jumpCumulativeTimer; // 当前可变跳跃剩余时间public float _coyoteTimer; // 当前土狼时间计时器private float _downTempSpeed; // 临时下坠速度（用于中断跳跃）private bool _isJumping; // 是否处于跳跃状态（长跳过程）public override void _Ready(){// 获取参数引用player = GetParent().GetParent<Player>();_jumpForce = player._jumpForce;_gravity = player._gravity;_jumpCumulative = player._jumpCumulative;_downSpeed = player._downSpeed;_jumpBufferTime = player._jumpBufferTime;_jumpCumulativeTime = player._jumpCumulativeTime;_coyoteTime = player._coyoteTime;}public override void _PhysicsProcess(double delta){Jump((float)delta);}private void Jump(float delta){if (Input.IsActionJustPressed("Jump")) //跳跃缓冲{_jumpBufferTimer = _jumpBufferTime;}else{_jumpBufferTimer -= delta;}if ((player.IsOnFloor() || _coyoteTimer > 0f) && _jumpBufferTimer > 0f) //设置跳跃{_isJumping = true;_jumpCumulativeTimer = _jumpCumulativeTime;}if (Input.IsActionPressed("Jump") && _isJumping && _jumpCumulativeTimer > 0f) //可变跳跃高度{player.Velocity = new Vector2(player.Velocity.X, -_jumpForce - _jumpCumulative * delta);_jumpCumulativeTimer -= delta;_jumpBufferTimer = 0f;}else if (Input.IsActionJustReleased("Jump")){_isJumping = false;}if (player.IsOnFloor() && MathF.Abs(player.Velocity.Y) < 0.1f) //土狼时间{_jumpCumulativeTimer = 0f;_downTempSpeed = 0f;_coyoteTimer = _coyoteTime;_isJumping = false;}else{_coyoteTimer -= delta;}if (player.RayHead.IsColliding()) //判断顶头{_jumpCumulativeTimer = 0f;player.Velocity = new Vector2(player.Velocity.X, _gravity / 4);}if (!player.IsOnFloor()){PlayerGravity(delta);}}private void PlayerGravity(float delta){player.Velocity = new Vector2(player.Velocity.X, player.Velocity.Y + _gravity * delta);}
}
总结
给大家的代码还算比较完整，我实践测试感觉手感还是不对，大家根据自己的需要进行修改优化吧
