+==== Movement ====
+Since the latest version of Gorilla3D (v0.8.3.1995) we support kinematic character movement.
+While previous versions worked completely on physics computation, the latest change added a more stable way.
+The true physics collision detection for characters works, but has bad sideeffects.
+The most serious problem was stuttering characters which bounced off the terrain.
+Also it was impossible to "climb" up steep hills because physics always dragged you down again.
+Even if this is more realistic, the usability was horrible for classic character movement.
+So in the latest component state the "UseRayCasting" property is activated. This changes the character controller from a dynamic rigid body to a kinematic body.
+Here we now cast a ray to detect the current position on objects instead of letting physics do the job.
+Nevertheless interaction with static or dynamic objects is still available.
+__Remark:__ In case you need the old behaviour, just switch "UseRayCasting" to FALSE.
+Control you raycast-movement by some properties like Slop, RayDirection and RayOffset.
+Especially the slopping value allows you to control f.e. the max. height of stairs to be able to walk.
+^Property^Description^
+|Slop|This only affects computation if UseRayCasting is enabled. The slop value is the maximum height a movement ray direction. Adjust this value to your specific scene, especially when walking of stairs or similar static objects. Default value is 0.5.|
+|RayDirection|The RayDirection defines in which direction the controller will be adjusted. Default direction is (0, 1, 0), which means downwards.|
+|RayOffset|Get or set ray offset from where the raycasting is started. The offset will be computed from current physics character controller position.|
