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 _jumpDeadZoneTime;    // 跳跃死区时间（短时间内跳跃输入无效）[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 _jumpDeadZoneTime;     // 按键死区（防止短按立刻进入长跳）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private float _jumpHoldZoneTimer;    // 按住跳跃键的持续时间public float _coyoteTimer;           // 当前土狼时间计时器private float _jumpCumulativeForce;  // 当前可变跳跃施加的力度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;_jumpDeadZoneTime = player._jumpDeadZoneTime;_coyoteTime = player._coyoteTime;}public override void _PhysicsProcess(double delta){Jump((float)delta);PlayerGravity((float)delta);}private void Jump(float delta){// 跳跃缓冲：按下跳跃键时记录缓冲时间if (Input.IsActionJustPressed("Jump")){_jumpBufferTimer = _jumpBufferTime;}else{_jumpBufferTimer -= delta;}// 死区检测：跳跃中按住跳跃键时间if (Input.IsActionPressed("Jump") && _isJumping){_jumpHoldZoneTimer += delta;}else{_jumpHoldZoneTimer = 0f;}// 可变跳跃高度控制（长按跳得更高）if (Input.IsActionPressed("Jump") && _isJumping && _jumpCumulativeTimer > 0f && _jumpHoldZoneTimer > _jumpDeadZoneTime){player.Velocity = new Vector2(player.Velocity.X, player.Velocity.Y - _jumpCumulativeForce * delta);_jumpCumulativeTimer -= delta;}// 提前松开跳跃键：终止可变跳跃else if (Input.IsActionJustReleased("Jump")){_jumpCumulativeForce = 0f;_isJumping = false;}// 满足缓冲与土狼时间，可以跳跃if (_jumpBufferTimer > 0f && _coyoteTimer > 0f){player.Velocity = new Vector2(player.Velocity.X, player.Velocity.Y - _jumpForce);_jumpBufferTimer = 0f;_jumpCumulativeTimer = _jumpCumulativeTime;_jumpCumulativeForce = _jumpCumulative;_isJumping = true;}// 玩家在地面或攀爬中，重置跳跃状态if ((player.IsOnFloor() || player._isClimbing) && MathF.Abs(player.Velocity.Y) < 0.1f){_jumpCumulativeTimer = 0f;_downTempSpeed = 0f;_coyoteTimer = _coyoteTime;_isJumping = false;}else{_coyoteTimer -= delta;}// 限制最大跳跃速度（防止过快）if (player.Velocity.Y < -_jumpForce){player.Velocity = new Vector2(player.Velocity.X, -_jumpForce);}// 顶头检测，取消跳跃力if (player.RayHead.IsColliding()){_jumpCumulativeTimer = 0f;_jumpCumulativeForce = 0f;player.Velocity = new Vector2(player.Velocity.X, _gravity / 4);}}private void PlayerGravity(float delta){// 空中才加重力if (player.IsOnFloor()) return;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
