Description:: Sets velocity vector of an object in m/s.
⚠
Since 2.06 each velocity component is limited to the range +-5000 m/s.
Groups:: Object Manipulation

Example 1:: _truck1 setVelocity [20, 0, 0];
Example 2:: Advanced method used for relative acceleration:
_vel = velocity _vehicle; _dir = getDir _vehicle; _additionalSpeed = 10; // in m/s _vehicle setVelocity [ (_vel select 0) + (sin _dir * _additionalSpeed), (_vel select 1) + (cos _dir * _additionalSpeed), (_vel select 2) // horizontal only ];

: 1.22 setVelocity will be affected by setDir and setVectorDirAndUp, so use it after them.
