| No game would be complete without the AI sensing the environment to be smart or preventing actors from walking across obstacles like they are big huge blocks. Sensors are something which many games neglect although they are important. The Drag[en]gine does not only provide sensors for simplifying and improving AI and collision detection it also improves tasks which otherwise can be expensive. For this various types of sensors are provided by the Drag[en]gine. | No game would be complete without the AI sensing the environment to be smart or preventing actors from walking across obstacles like they are big huge blocks.

| Touch sensors track a given slab of space for intrusion of terrain geometry or colliders. A touch sensor is located at a position in the world and owns a set of shapes. Each shape is tracked individually for objects entering and leaving. Whenever a terrain or colliders enters or leaves a shape a notification is send to the game scripts. This is an easy way to realize triggers as in contrary to physics system colliders touch sensors register also objects passing through a shape during one frame update ( for example during slight lag ). In addition the objects in contact with a shape are stored and can be queried at any time. Especially collision testing ( collider hits, collider move hits and ray hits ) can be conducted on the content of a shape. This makes the touch sensor a very efficient collision testing facility since only a small set of the world is tested. No expensive collision tests are required. Paired with notifications fast sensing of your environment can be conducted. If possible group collections of shapes into one touch sensor to improve spacial locality. This is usually the case for characters sensing their direct surrounding. | Touch sensors track a given slab of space for intrusion of terrain geometry or colliders.
