GetPlayerCameraFrontVector

From SA-MP Wiki

This function was added in SA-MP 0.3a and will not work in earlier versions!

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.

Note: 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.

Parameters:

(playerid, &Float:x, &Float:y, &Float:z)

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.

// A simple command to manipulate this vector using the
// positions from GetPlayerCameraPos. This command will create
// a hydra missile in the direction of where the player is looking.

			Float:object_x, Float:object_y, Float:object_z;
 
		// Change me to change the scale you want. A larger scale increases the distance from the camera.
		// A negative scale will inverse the vectors and make them face in the opposite direction.
