whether one unit in coordiante corresponds to 20 meters?

just like the subject:whether one unit in coordiante corresponds to 20 meters in extendsim?


to be specific, like the circle moves from coordinate (20,20) to (21,20), the distance between this two successive points coresponds to 20 meters in extendsim? correct or not? thank you for sharing your ideas?

在3D中,默认的设置是20像素对应1米,不知道在2D的坐标与米之间关系是多少?

这个关系和时间关系一样,是你自己设定的,可以认为坐标上的一厘米对应 一米,也可以认为对应10米,只要统一就可以。
