Since the rules on page 55 of Total Warfare for sideslipping don't mention buildings would they follow the rules listed there as per other terrain types?
Rule section in question:
WiGE vehicles entering a hex greater than one level above their current hex likewise crashFrom the previous clarification: "Buildings add - for the purposes of WiGE movement - their number of levels to the height of the underlying hex." Given that, if a WiGE sideslips into a building hex which has a total combined (ground level + building level) greater than that of the hex the WiGE started in, it crashes. It cannot spend additional thrust to try & climb.
Which brings to mind a further clarification of if a building in the side slip path is a level too tall but has insufficient CF to support the WiGE I would assume that it would still result in a collision rather than the WiGE collapsing the building by a level correct?
Correct. CF of the building is irrelevant; if you side slip into a taller building, you crash.
And just thought of one more possible edge case scenario that the new ruling may effect that is not addressed in the side slipping rules on page 55 of Total Warfare.
If a WiGE sideslip does take it into a hex with a building that rises only one level above the underlying terrain but does not have sufficient CF does it immediatly collapse?
Side-slipping WiGEs can't gain altitude, so they crash.
Edge case - forward flight. Imagine a straight row of L1, CF10 buildings on flat terrain. A Pandion starts with one building just ahead of it.
It pays the extra MP to climb, then moves forward one. The building then collapses, taking it back to above L1. So it has to spend extra to enter the second hex, which also collapses, and so on ... the image amuses me. Of course, if it tries to enter the last hex without the extra MP required to climb, it crashes. ore amusing. :)
