GetPlayerCameraFrontVector

คำอธิบาย

This function will return the current direction of player's aiming in 3-D space, the coords are relative to the camera position, see GetPlayerCameraPos.

Name	Description
playerid	The ID of the player you want to obtain the camera front vector of
Float:x	A float to store the X coordinate, passed by reference.
Float:y	A float to store the Y coordinate, passed by reference.
Float:z	A float to store the Z coordinate, passed by reference.

tip

In 0.3a the camera front vector is only obtainable when player is inside a rhino, S.W.A.T tank, fire truck, or on foot. Since 0.3b the camera data can be obtained when the player is in any vehicle or on foot.
