这段时间工作比较空闲,想做个抽奖系统,发现网上的抽奖系统看不懂,然后自己做了一个可以随意定义奖品概率,不管什么时候停下来指针最终都会转到指定的奖品哪。
废话不多说,动手一步一步来。
这个抽奖系统就使用了两张图片,一个指针,一个圆形的图片。
然后做一个预制体,图片就是圆形图片,image type选择filled,fill amount控制这个图片的面积大小,同时也是该图片的概率,text组件是该奖品的名称。
再接下来就做一下界面布局的工作
bg就是那个灰色的图片,rotate是个空物体,用来挂在脚本的(dialrotate.cs和slot.cs),cloneparent也是个空物体,作为预制体的父物体,要注意的是cloneparent中心那个蓝色的圆圈要和rotate的蓝色的圈的位置一致,界面布局工作完成。
接下来到代码了,slot.cs脚本,一开始会实例化奖品,k键和l键可以随意修改奖品名称,概率(这里概率做了限制,需要使用的自己修改一下代码即可),空格键会随机抛出物品,并且开始旋转,鼠标右键是停止转动(想什么时候停下来都行,最后都会得到所抛出的物体)dialrotate.cs脚本用于处理旋转的。这两个脚本涉及到一些数学计算,慢慢理解即可。
以下是这个工程的脚本,需要的话直接复制黏贴即可使用
slot.cs
