You might wonder why I check whether the method is static at the start of my parameter size calculation, then initialize the stack frame slot to zero if it is (as opposed to one if it is not).
您可能会奇怪为什么在开始参数大小计算时要检查方法是否是静态的，如果是静态的，将堆栈帧槽初始化为零(不是静态正好相反)。
The next loop section controls setting pixels coordinates only if the frame at that position is greater than the start frame.
循环的下一部分控制像素坐标的设置，条件是当前时间帧在起始帧之后。
From the name you would think it controls a random starting frame but it does not, it just causes the animation to start at the specified frame.
从这名字看来，你会想，这是控制一个随机启动帧，但其实不是的。它是控制动画从指定的帧开始的。
