原点在图片外面？不会吧……运动后它的角度怎么办？

这种孤线运动轨迹，思路是什么呢？

@fangyc 原点设在哪都阻止不了红球的自转吧？红球好像是不应该自转的……注：那个红球之外的是不动的，球是要动的……

　　　　PS：只是用素材……续写轨迹什么的，我文字不好……乱入下轨迹的世界观还是可以的……

可以调用Sprite的angle（旋转角度）方法来旋转图片，原点（ox，oy）设在图片中心（width/2, height/2）
话说楼主在做轨迹的游戏吗？

那你得吧图切开用不同的sprite来显示吧

1、参考圆的方程(初中数学水平)，然后确定x,y
2、参考六边形，做法也不难但效果也不差

圆的话，事先生成一个数组，数组包含坐标信息

PRECISION = 360
RADIU = 100
a = (0...PRECISION).inject([]){|a,b|a<<[(RADIU*Math.cos(b*2*Math::PI/PRECISION)).to_i, (RADIU*Math.sin(b*2*Math::PI/PRECISION)).to_i]}

复制代码

PRECISION表示划分的精度，RADIU代表半径
这样a里面保存的就是坐标信息，可以在游戏开始设为常量。这样何以匀速转动，如果非匀速的话，
可以把PRECISION设置高点，用一个浮点变量作为位置信息，使用时取整就行

这个用六边形的移动方法就差不多了

做动画一帧一桢贴上去

用极坐标系记录位置，刷新的时候用三角函数转换 oxoy要放在图片中心
强烈求素材，当初做过这种菜单，没素材不好看就放弃了

#==============================================================================
#
# - INTRODUCTION -
#
# This system implements a Plug 'N' Play Ring Menu
# Movement based off XRXS, Dubealex & Hypershadow180's original XP Ring Menu,
# which was devised through some simple, but clever trigonometry
#
#------------------------------------------------------------------------------
#
# - USAGE -
#
# Any additional scenes that are added to the menu require an icon
# Place them in the pictures folder, they are advised to be 48x48 pixels
#
# The name of the icons must be of the form:
# [Command Name] Icon
#
# For example 'Items Icon.png' or 'Equipment Icon.png'
#
# If you are unsure what it needs to be called, wait for the error message,
# then call it the name of the file it can not find
#
#------------------------------------------------------------------------------
#
# - COMPATIBILITY -
#
# Additional scenes should be automatically added assuming thier creators
# utilise the 'add_original_commands' feature in Window_MenuCommand
#
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#
# This script redefines the following methods:
# * create_status_window (Scene_Menu)
# * on_formation_ok (Scene_Menu)
# * on_formation_cancel (Scene_Menu)
# * draw_character (Window_Base)
#
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
