Line of Sight

[ibmjackson]

I'd like to see a line of sight function added to the core.  The user would pick two objects and the function would check the line of sight between those two objects.  The results could be a graph of elevation changes vs distance between the two objects (which would be most useful) or a simple green or red check indication the line of sight was either clear or blocked.  Objects could be steer points (making sure no mountains were in the way for example) or vehicles on the ground (can this group/unit see another group or unit and attack).
