World Limit

#1 I'm not sure if this exists (it might, I just haven't seen it) but you can figure this information out pretty quickly by looking at the position of the object at impact. Then you can just react accordingly.

#2 I don't think there is anything that directly tells you wich wall of the world limit was hit. But, you can probably do this in your code. For example, something like this in your ProcessTick() method:

T2DWorldLimitComponent EndOfWorld = 
_sceneObject.Components.FindComponent<T2DWorldLimitComponent>();
 
if (_sceneObject.Position.X >= EndOfWorld.MoveLimitMax.X)
     doSomething(); //hit the right wall
 
if (_sceneObject.Position.X <= EndOfWorld.MoveLimitMin.X)
     doSomething(); //hit the left wall
 
if (_sceneObject.Position.Y >= EndOfWorld.MoveLimitMax.Y)
     doSomething(); //hit the bottom wall
 
if (_sceneObject.Position.Y <= EndOfWorld.MoveLimitMin.Y)
     doSomething(); //hit the top wall

If you add this to your MovementComponent's ProcessTick() method, you should be able determine which wall you hit based on the position of the owner scene object relative to the defined world limits.

A good use of this kind of function is a scrolling map camera, where the cursor roams around the scene and then only pans to other areas of the scene when the cursor hits the edge of the viewable area. This might not be what you're looking for, but hopefully it might point you in the right direction.

#3 Excellent, thanks very much.
