hitNormal
- Returns the normal as a 3D vector relative to the world coordinates
- float list [ nx, ny, nz]
nx:
- cosine of normal to world x-axis
- cosine of normal to world y-axis
- cosine of normal to world z-axis
Ray Sensor:
- Ray Sensor is triggered when the first game object is detected.
- Ray Sensor is reset when all game objects are no longer detected.
- Triggered: One positive pulse is sent to the connected controller(s).
- Reset: One negative pulse is sent to the connected controller(s).

Sample Code

################ Get the normal of the object face
# import bge module
import bge
# get the controller
cont = bge.logic.getCurrentController()
# get the sensor attached to the controller
# my sensor is named Tripwire
sen = cont.sensors["Tripwire"]
# get the normal of object face
face_normal = sen.hitNormal
