SetHologramPosition()

bool Hologram::SetHologramPosition ( vector startPosition, float minProjectionDistance, float maxProjectionDistance, inout vector contactPosition )

inlineprotected

Sets hologram position based on player and projection distance.

Аргументы

startPosition	start position
minProjectionDistance	lower distance limit
maxProjectionDistance	higher distance limit
inout	contactPosition is position of the hologram contact with ground/object

Возвращает

true if hologram is floating (is on the near or far edge)
