Is there any efficient stock to determine distance to ground from the entity's origin? Currently I am using traceline native to achieve that. Basically I get origin of the entity, substract around 8000 from Z axis (origin[ 2 ] -= ..), do the trace line native and finally get hit origin. Then I can determine distance to ground by vector_distance. Is there anything more efficient?

That's good. Even pfnDropToFloor (EngFunc_DropToFloor, drop_to_floor) does it in a similar way, but still does tracing.
