Description:: Set object's up vector. Direction of the object remain unchanged. Default object's vectorUp is [0,0,1].
Groups:: Math - Vectors

Example 1:: Turn object upside down: _obj setVectorUp [0,0,-1];
Example 2:: Align object with the terrain underneath: _obj setVectorUp surfaceNormal position _obj;

: setVectorUp can only influence an object's bank. It can not influence pitch. Example: player setVectorUp [0,1,0] If the player is facing 0 degrees (north), then this will do NOTHING.
If the player is facing 90 degrees (east), then this will make him bank 90 degrees to his left.

: Command can be also used to rotate camera in all three axis (which also mean it is possible to set camera bank).

: It is possible to change both pitch and bank of an object (surfaceNormal application for instance). Assuming an ammo box in the following example is facing North (default direction is 0): _ammobox setVectorUp [0,1,0]; // box is pitched 90 degrees forward _ammobox setVectorUp [1,0,0]; // box is banked 90 degrees to the right However the above will stop working as soon as you attach the box to something. The following trick however will work in this case: _ammobox attachTo [player, [0,2,1]]; _ammobox setVectorUp [0,0.99,0.01]; // box is pitched ~90 degrees forward _ammobox setVectorUp [0.99,0,0.01]; // box is banked ~90 degrees to the right
