@H_403_1@搅拌机系统在r73中推出,我一直在尝试将我的游戏更新到这个新系统.
除了一件事我还在ALMOST.某些具有某些几何形状的动画的交叉渐变在r72中不存在轻微的延迟.我劫持了r72的BlendCharacter和Animation功能,以允许回调,它的效果很好.在73中,这不是必需的,它通过事件触发器内置此功能.
在下面的小提琴中,一切都按照预期(r72)奏效.

除了一个动画(Magic Attack)(Magic Attack),返回到空闲动画之前,这个(r78)的作品几乎是很好的.在其他型号上,这是近战动画,有些动画根本就没有问题.超级混乱,因为它们都在72中正常工作.

为什么会发生这种情况？
更新：我注意到这个问题并不局限于混合动画.我现在刚刚循环的动画有一个延迟！
