The first number (hsize) is the horizontal
size of the hull, the second (vsize) is the vertical
size, and the third (voffset) is the vertical offset
of the hull relative to the entities' origin. For instance, -narrow
32 32 0 -fat 64 48 8 gives the default hulls. All map entities should
be built with the same hull sizes as the level. 4 predefined vectors contain
the current level's hull box sizes for evaluation in functions: hull_narrowmin[3], hull_narrowmax[3], hull_fatmin[3],
and hull_fatmax[3]. They contain the x,
y, z minimum and maximum values of the narrow and fat hulls. For sprite entities, its origin is the geometric centre of the
bitmap. For map or model entities, the origin is its coordinate origin given
by the editor. If you want the model to be able to climb stairs, simply place
its origin into a higher position of its body. The highest step the model can
climb is given by the difference between its lower hull border and it's feet.
If you don't want the model to climb at all - if it's a car, by example - place
its origin into a low position. But be careful not to place it too low, otherwise
its hull may penetrate the floor, and the model won't be able to move at all.
The origin is also the reference point for model rotations.
Parameter
hsize
horizontal expansion of hull
vsize
vertical expansion of hull
voffset
vertical offset to origin
Remarks:
It's not a command it's a Map Option parameter for building the map.
