// NET - field that shared on client across network
// Modifiers:
// [player] - all notify for this field is valid only for client entity
// [all] - valid for all ents
// [phys] - valid only for rigid bodies
// [solid] - only for solid entities
// [push] - only ents with SOLID_BSP and MOVETYPE_PUSH have affect on this field
