-------------------------------------------------------------------------------- 1 | Navmesh数据导出工具 2 | ==== 3 | ![](picture/photo1.png) 4 | ![](picture/photo2.png) 5 | ------- 6 | ### 说明 7 | unity自带的navmesh由于算法没公开，服务端要判断该移动点是否合法比较困难，很多时候需要自己实现一套A*费时费力， 8 | 本工具就是导出navmesh的各个三角形坐标数据，然后服务端只需要判断该点是否在三角形内就为之合法。
9 | 10 | ### 如何使用 11 | 1.首先你需要自己在unity里编辑好可行走范围
12 | 2.然后点击菜单Tools/Export NavMesh Data即可
13 | 14 | ### 如何测试 15 | 1.首先把navmesh目录下生成的mesh拖进场景
16 | 2.然后点击菜单Tools/NavMesh Data Test即可 (移动TestPoint即可)
