首先用 Inverse Transform Location 把一个世界位置的向量转换成一个物体的本地坐标的向量。变换完了之后呢,我们不需要 z 轴只需要 x 和 y,其实直接把这个 x 和 y 赋值就可以看到效果了,但是我们还得乘一下这个 DPI Scale(1/Viewport Scale) 这东西是给多平台 UI 做缩放用的,我也不太了解,具体内容去
FTransform.InverseTransformLocation(FVector Location) 父空间坐标转局部空间坐标。 FTransform.TransformLocation(FVector Location) 局部空间坐标转父空间坐标。 FTransform.TransformRotation(FRotator Rotator) 局部空间旋转转父空间旋转。 MakeRotFromX(FVector X) 假设目前X轴向量为(1,0,0),现在要使它变成输入的新向...
