ai_debug_nav

The ai_debug_nav console command is a debugging tool used to examine navigation problems in NPCs. When enabled, NPCs will report their navigation decision making process to the console. It's primarily a tool used by programmers to determine where navigation problems lie. Some familiarity with the AI navigation system is needed to make use of the output.

Example

Among other output, ai_debug_nav provides useful information for the following events:

• NPCs creating navigation goals. Provides a detailed breakdown of the goal parameters.
• NPCs building routes, both succeeding & failing.
• NPCs modifying their route while walking it, usually due to simplification.
• NPCs attempting to stop their movement.
• NPCs jumping.
• NPCs disabling collision with vphysics simulated entities.

• ai_debug_nav 1
  • Turns navigation debugging output on.
