   AI Content Examples

The following AI content examples are provided as a stepping off point from visual example to documentation article. You will find various topics such as pathfinding and complex setups like the Tactical Point System for environment evaluation.


The AI system that ships with CRYENGINE is a proprietary solution that extends from specific engine modules. The basis of the AI system is housed around the mechanics that stem from the core gameplay of the Crysis series. This allows for you to have numerous types of AI that can extend in both complexity and memory footprint. The system has a few core components that are named pathfinding, behavior trees, and query systems. Utilizing these three resources you are able to have an AI that not only has a behavior with specific animations, but also has the ability to evaluate the dynamic environment it is in and make educated choices. On top of this we are given tools that allow for cover, along with Smart Objects that allow for off-mesh navigation to make your AI even more dangerous.
