计划是做魔法阵生成器的,后来仔细研究,需要大量的解析几何 数据结构 拼凑算法 随机算法 等等相关内容,所以不可能一次性解决问题了.所以发来当前进度描述一下过程以及想法.不一定能坚持写下去,到了后面的规则制定我头都大了.
--------------------------------------------------------------------------
用途:计算2D飞行游戏弹道,比如彩京那样的,放置游戏人物,屏幕保护,媒体播放器的视觉效果.
一个6边形,根据r扩散.取r两次.则有两个顶点列表.根据这两个停电列表可以表示弹道轨迹.然后旋转魔法阵,得到新的顶点列表,重复上述操作,可以得到任意发散的子弹图形
如果对两个子弹的弹道加上初始速度以及加速度,则可以表示变速直线运动,创造更华丽的子弹组合效果.
如果有了随机生成魔法阵算法,理论上游戏人物的初始位置排列都可以生成
虽然可以随机出现,但是如果用魔法阵顶点来做,会更有规律,生成的敌人组合排列更强,更加合理.因为魔法阵的生成都是有规律的,攻击型的图形表示可以放攻击型人物等等
因为牵扯随机算法,就是给出要求("比如咒语"),然后根据条件生成魔法阵的过程,就是要求根据"指定规则"后的映射
比如你给出一系列条件:攻击型5个,防御性一个,防御为主,同时复杂程度不超过N(魔法阵外层常量)....其他条件等等.然后根据算法,提取出数字,用作权值.生成魔法阵
N的取得是根据权值而定,就是N越大,魔法阵面积越大,外围图形越多(有隐形的辅助线) 而且如果敌人有人死亡,比如攻击的减少了一个,而且还是防御为主..那么再次带入还能生成新的魔法阵 重新排列防守阵型
强烈怀疑,一开始提出魔法阵的人,绝对不是因为好看!!只不过没有人认真研究罢了.这个很像八卦阵的,全都是数学以及数据关系
---------------------------------------------------------------------------
不废话了...
魔法阵生成系统的第一步 画一个正N角星
这个是基础的基础,正N角星包含正N边形,当N大于一定程度的时候可以近似表示圆,我们需要的顶点列表都可以被线性表描述出来,从而根据下标筛选所需的点.
对于正N角星,基础就是所在外接圆,然后通过极坐标->平面坐标转化求出顶点
这个就很简单了,高中内容
-------------------极坐标 到 平面坐标的转化--------------
Function Trans(ByVal jizuobiao As CAPI, Optional ByVal StartX As Integer = CStartX, Optional ByVal StartY As Integer = CStartY) As System.Drawing.Point
Dim P As System.Drawing.Point
'P(x,y)就是极坐标的 (Sin a)x 半径r 以及cos a x半径r
P.X = StartX + CLng(Math.Sin(jizuobiao.a) * jizuobiao.r)
P.Y = StartY + CLng(Math.Cos(jizuobiao.a) * jizuobiao.r)
Trans = P
End Function
----------------------------------------------------------------------
另外微软提供的arraylist似乎没有环形链表,尝试用他的queuq的时候,也不好改动,于是我索性干脆自己写了一个.其中包含以下要素:
-------------------------------
Public Class Node
'下一个节点
Public NextNode As Node
Public Container As RoundQueue
'上一个节点
Public PrevNode As Node
'元素信息,用Object表示
Public objData As Object
Public visitFlas As Integer
'插入节点
Public Function InsertNextByData(ByRef d As Object) As Node
Public Sub deleteNode()
Protected Overrides Sub Finalize()
End Class
Public Class RoundQueue
'Public EnableBack As Boolean
'虚拟的头节点
Public Root As Node
Public TotalNodes As Long '总数
Public CurrentNode As Node '当前指针
Public Sub New()
Public Sub New(ByRef L As ArrayList)
Public Function InsertNode(ByRef tarNode As Node, ByRef newNode As Node) As Node
Public Function InsertNode(ByRef tarNode As Node, ByRef newNode As Node, ByRef DataOfNewNode As Object)
Public Function MovePrev() As Node
Public Property GetData() As Object
Protected Overrides Sub Finalize()
Public Sub Dispose()
End Class
--------------------------------------------------
有了以上材料作为基础,开始研究算法.
网上找到的大部分都是LOGO语言的,没办法,人家天生适合画这个.
给出函数
DrawAngle(ByVal Num As Long, ByVal Steps As Long, ByRef map As Bitmap, ByVal x As Long, ByVal y As Long, ByVal r As Long, ByVal basea As Single, ByVal penA As Drawing.Pen)
提供角的数量,跨越点数,目标图像,圆心半径起始角度(用于旋转),以及画笔(颜色,粗细)绘制图形
1 所有的大于2的奇数的正N角星都能一笔画出
(也就是我们可以一直用.nextnode来画)
2 除了六角星以外 所有大于3的正N角星都能一笔画出
(一笔画出就是没有跳跃间断点)
3 大于5的正N角星,会有 ((边数-1)/2)上取整种有效画法
不仅仅是一种画法,当边数等于0或者自身的时候无意义,重复的图形无意义
4 间断点位置,(当角的数量/间隔点差(包含自身))=K的余数为0的点就是断点.
5 当断点出现的时候,当前图形就是基本图形,整个图形在此基础上错位 K次就是整个图形
6 基本图形错位K次的结果不会有任何重复线段以及顶点,而且可以遍历整个节点
以下以正8角星为例(3,4,5,6都有特例,所以不好办) 如图
------------------------------------
算法:
1 创建m的元素的数组
2 根据m的个数,取得间隔的角度a
3 根据极坐标转化,得到第一个顶点的位置
4 依次类推取得全部顶点
5 将顶点加入环形链表(严格的说,不算队列)
6 绘制,检测错位
