src | 拖动的源点。 |
dest | 拖动的目标点。 |
srcPosition | 被拖动对象在 src 射线上的 3D 位置。 |
constraintDir | Normalized 3D direction of constrained movement. |
float 沿 constraintDir 移动的距离。
将鼠标拖动映射到沿 3D 空间中一条直线的运动。
某些类型的 Handle(例如箭头)会涉及沿 3D 空间中一条直线的运动。例如,在拖动鼠标时,变换组件的位置箭头会沿其本地 X、Y 或 Z 轴方向移动对象。CalcLineTranslation 函数按照 Unity 内置工具的惯用方法将鼠标的移动转换为沿一条 3D 线的受约束移动。
