Make new navigation paths for zbots.

NAV MESH EDITING

bot_nav_edit [0,1]

Setting this cvar to 1 allows hand-tuning of the bot's navigation mesh. Once edit mode has been activated, the bot_nav_* commands can be used.

bot_nav_zdraw

This value determines how high above the ground to draw the "nav mesh" when in nav edit mode. If the terrain is very irregular or highly sloped, it can be useful to increase this value to 10 or 15. The default value is 4.

bot_quicksave [0,1]

If nonzero, the analysis phase of map learning will be skipped. This is useful when iteratively hand-tuning nav files. Note that withough this analysis, the bots will not look around the world properly.

NAVIGATION MESH EDITING

Each of the following bot_nav_ commands operate on the navigation mesh, allowing hand-tuning of the automatically learned data. It is recommended that these commands be bound to keys for ease of use while editing.

CAUTION: There is no "undo" operation. Save your navigation mesh often.

bot_nav_mark

Marks the currently selected nav area for later operations.

bot_nav_delete

Deletes the currently selected nav area.

bot_nav_split

Splits the currently selected nav area into two new nav areas, along the white split line.

bot_nav_merge

Merges the currently selected nav area and a previously marked nav area into a new, single nav area. The merge will only occur if the two areas are the same size along the merge line.

bot_nav_connect

Creates a ONE WAY link from the currently marked area to the currently selected area, telling the bots they can walk FROM the marked area TO the selected area. For most areas, you will want to connect the areas in both directions. However, for some "jump down" areas, the bots can move one way, but cannot get back the other.

bot_nav_disconnect

Disconnects ALL connections from the currently marked area to the currently selected area.

bot_nav_begin_area

bot_nav_end_area

These two commands allow the creation of new nav areas. "bot_nav_begin_area" marks one corner of the area. "bot_nav_end_area" marks the opposite corner of the area and creates it. To cancel the operation, issue a "bot_nav_begin_area" command again.

bot_nav_splice

Creates a new nav area between the currently marked area and the currently selected area, and bidirectionally connects the new area. This command is especially useful for creating sloped nav areas.

bot_nav_crouch

Flags the currently selected area as "crouch", requiring bots to crouch (duck) to move through it.

bot_nav_jump

Flags the currently selected area as "jump". This is a hint to the bots that they should jump to traverse this area.

NAVIGATION MESH PROCESSING

bot_nav_analyze

Analyze the navigation mesh to determine Approach Points and Encounter Spots. This may take several minutes based on the size and complexity of the map.

NOTE: This command requires one bot to be in the game. The recommended procedure is to save the mesh, add a bot, and quickly enter bot_analyze.

bot_nav_save

Saves the current navigation mesh to disk. The navigation mesh ("nav" file) is automatically named to correspond to the current map file. For instance, if the map is de_dust.bsp, the nav file will be de_dust.nav.

bot_nav_load

Clears the current navigation mesh, and loads it from disk.
