Navigation Meshses are boxes that can be placed and subsequentially adjusted to allow the player to move throughout the game world. Movement and basic gameplay is impossible without navigation meshes.
Placing Navigation Meshes
Before you place a navigation mesh make sure that you will be able to view it. You can accomplish this by pressing ctrl+alt+f, selecting debug and then checking the box marked "areas."
1) Right click inside of the editor window and close your current tool (right click and then click "Close active tool")
Errors - If the option to close your current tool does not appear then you are good to go and should proceed to step 2.
- If the only option available on right-click is "debug" then double click on a layer inside of your Scene tab.
2) Right click inside of the editor window and select "Navigation" then "Add Path Area."
3) A purple navigation mesh should have appeared. Now all you need to do is place the navigation mesh.
4) You do not want to make you navigation mesh too large. It is far better to make a series of small meshes than one large one.
5) You also must make sure the the bottom of the navigation mesh is slightly below the terrain or the mesh will not function correctly.
6) Finally the navigation mesh does not update in real time. Instead it must be generated. To do this click on the "tools" tab and then click on "navigation mesh." From there click on "collect geometry," "generate navigation mesh," and "filter mesh," in order. Every time you adjust a path area you will need to click these three buttons again.
