Description

Description:

Sets object heading. Angles are measured in degrees clockwise from north, and regular range goes from 0 to 360 (0° = N, 90° = E, 180° = S, 270° = W). Negative angles represent a counter-clockwise angle.

Multiplayer:

See notes below for more details on setDir behaviour.

Syntax

Syntax:

object setDir heading

Parameters:

object: Object

heading: Number

Return Value:

Nothing

Examples

Example 1:

unit1 setDir 45; // will set unit1 to face North-East

Example 2:

unit1 setDir -675; // will also set unit1 to face North-East (= 45-360-360)

Example 3:

unit1 setDir 30; unit1 setFormDir 30;// needed for AI to keep the given direction

Though effects of this command remain local, you can do a setPos afterwards to synchronize the direction on all machines in MP. myObj setDir 90; myObj setPos getPos myObj;

In ArmA, the effect of setDir is synchronized across the network.

In OA 1.59 the comment of Manny still holds true for createVehicle'd empty vehicles by the server. For the player object a local setDir alone is enough.

In Arma 3, setDir affects vectorUp, vectorDir and velocity of the object it applied to. While this is not noticeable with stationary objects, a moving objects will have its orientation and velocity reset. So if you are planning on using setDir on a moving object, make sure you read the velocity value before and restore it after if you want the object to continue to move. _vel = velocity _object; _object setDir 45; _object setVelocity _vel; With orientation it is a bit more complicated. setDir resets vectorUp to [0,0,1] and changes vectorDir accordingly to accommodate set direction. If your object's vectorUp is not [0,0,1] and you want to keep it this way, then you have to use setVectorDirAndUp to change object's direction not setDir. This is also the reason why it is better to use setVectorDirAndUp instead of setDir on attached objects for a better control of object's orientation.

Make sure you setDir BEFORE you set position. Setting direction after set position could lead to unpredictable behaviour. For example main part of the hospital building in Arma 3 can lose collision detection near both side entrances. AI will also get confused and will stop detecting obstacles if setDir is called after setPos.

setDir is not propagated across the network when used on mines. Clients will see mines facing zero. This is especially noticeable on tripwire mines.
Use remoteExec to run the setDir command on the mine for all clients.
