Unity笔记-29-ARPG游戏项目-06-弓箭
基本要求说明
点按R键,进入弓箭视角,点按鼠标左键进行射击,射击距离,伤害以及削韧效果根据蓄力时间而定,每次拉弓到射击的持续时间会不断蓄力,射击距离伤害,削韧效果具有上限,一直蓄力不会无限制的增加距离,伤害,削韧效果;
弓箭视角下的移动不会改变人物朝向,人物朝向一直朝向前方,通过再次点按R,跳跃,翻滚等操作可以退出弓箭视角,受到攻击造成硬直时也会退出弓箭视角
进入弓箭视角时,屏幕中央会出现射击符号,退出则消失,同时人物的动作朝向应当指向射击符号的位置
处于受击硬直,空中,攀爬时无法进入弓箭视角
展示图如下:
基本思路
点按R时,装备弓箭,并播放拉弓动画,再次点按放箭,播放放箭动画,暂时不配置弓箭拉绳的弯曲动画,可能比较奇怪,暂时以实现功能为主。箭的运动需要通过箭的脚本控制,由于这里我们将人物模型放在的屏幕的右边,因此如果不去修正箭的运动的话,只是让箭沿着朝向进行抛物线运动,它是不会飞向屏幕中央的,实际体验下很难射中目标,因此,还需要通过代码修正运动路径。
代码
仅说明箭的运动路径修正代码

箭还未发射时,箭对象没有碰撞体也没有刚体,如果这时候就给到这些组件,在人物移动时,箭就不会跟随人物移动。
执行放箭执行前,首先赋予箭碰撞体和刚体,并关闭重力,通过代码去赋予Y轴加速度,并赋予与朝向方向相同的初速度,发射后,通过计算摄像机朝向与箭朝向的角度,不断修正箭的角度与摄像机朝向相同,但不是瞬间,通过类似Lerp函数的方法不断修正,通过不断调试即可修正运动路径。
动画状态机
放箭通过触发控制
