默认情况下,不同场景中的导航网格未连接。使用 Application.LoadLevelAdditive() 加载另一个关卡时,需要使用网格外链接 (Off-Mesh Link) 连接不同场景中的导航网格。
在此示例中有两个场景:_Scene 1_ 和 Scene 2。Scene 1 有一个网格外链接从一个可行走区域开始,并在 Scene 2 中的一个可行走区域上着陆。可根据需要设置多个连接场景的网格外链接。
在创作时,连接场景的网格外链接的另一个端点是未连接的。加载新场景后将重新连接网格外链接。
如果多个场景的导航网格在同一区域重叠,则位置选取对象可能是该位置的任意导航网格。此情况适用于使用导航网格 API 的代理、网格外链接和位置选取。应该创建跨越网格外链接的场景,使这些链接仅在一个导航网格上明确开始和结束。重叠的导航网格区域不会自动连接。
