cos.bin

Chinese, Simplified

以下的 cos 函数全部使用角度单位。
游戏用来计算余弦值的文件。其格式可在这里找到:http://will.kirk.by/labs/tt/edge/cos.bin
EdgeTool 反编译这个文件可以得到 cos.txt。这是一个有 181 行的文件,第 i 行中写的是 cos(i-1) 的值。
每个值精确到 1/256,即 0.00390625。你不能填写正负无穷大,因为每一行的数字都必须有取值范围:[-128,127.99609375],即 [ -128,128 )
如果删除这个文件,在游戏中玩家将不能通过倾斜方块来吃棱柱。
P.S. 虽然在通常情况下余弦的值域是[-1,1],但是很幸运我们可以使用一些更加大的值来实现一些神奇的功能。
