Bots are known to hesitate when crossing narrow streets or overgrowth or ditches.
I've done two simple things:
Changing values in ai.ai
aiPathfinding.setActiveMap Vehicle
aiPathfinding.map.maxSlope (28)
aiPathfinding.map.addVehicleForClusterCost Tank
aiPathfinding.map.addVehicleForClusterCost ArmedCar
Changing values in aipathfinding.ai
aiPathfinding.createMap Vehicle
aiPathfinding.map.maxSlope (20)
aiPathfinding.map.headClearance (3.5)
aiPathfinding.map.radius 2.5
aiPathfinding.map.allowedHeightDiff (5)
And at least, in my PC they successfully do this in Goodwood:
I dunno if this is the result i should have expected when increasing the encased () values.
The hanomag in first pic, finally crosses the underpass smoothly with little hesitation. The Goodwood Panther drive through the railway now, they don't reverse and forward too many times. Lastly, the Panzer 4 was shown to be able to cross the underpass too, not only the hanomag!
