ATTACH OBJECT TO UNIT/OBJECT

To attach object to unit or another object, follow theses steps :

Place invisible heliport for exemple, and name it holder

Place object you want (for exemple a lamp) to attach to heliport and past in INIT box :

this attachTo [holder,[0,0,5]];

Your object (lamp) will be attached to invisible heliport with height of 5 meters

To rotate your attached object, place the following code :

this setDir 180;

180 is the rotation direction on 360 of your object

So you can do it for our exemple in INIT box of your lamp :

this attachTo [holder,[0,0,5]]; this setDir 180;
