R0T 1 Posted June 12, 2014 (edited) Hey Folks, i wrote a skript for a random patrol but now stuck on a expression that the game throws at me and i can't find my mistake :confused: the error if (((getPos leader _Pat)distance _posNew)< 35) then { if (_wait) then {> Error position: <_posNew)< 35) then { if (_wait) then {> Error Undefined variable in expression: _posnew File C:\Users\Sam.N.Raub\Documents\Arma 3\missions\JSP_JustSimplePatrol.Altis\JSP.sqf, line 212 Error in expression <; }; My problem is this error occurs just for the first run after i started arma 3 and run the skript the first time. The second time i run the skript the error is gone.For me it looks like i don't have defined the variable _posNew (is a array that have a position in it [x,y,z]) not right but i did it at the beginning of the skript. I hope someone can help. Im really at the beginning with scripting. When anybody see something that could be improved ... pleas gimmi a hint so i can learn somthing new. Her is the whole skript /*--------------------------------------------------------------------------*/ /*------------------------------- - JSP.sqf - ------------------------------*/ /*--------------------------- - JustSimplePatrol - -------------------------*/ /*------------------------------- - by R0T - -------------------------------*/ /*--------------------------------------------------------------------------*/ //Chance her if you want them to wait longer or shoorter on the Waypoint. _randomWait = 10;

Tajin 348 Posted June 13, 2014 Try adding this at the beginning: waitUntil {!isNil "SHK_pos"}; I assume the error occurs because it tries to get a position from SHK_pos, before that function is initialized. Share this post Link to post Share on other sites
R0T 1 Posted June 13, 2014 Hey Tajin thx allot that fixes my prob. I thought the init.sqf would be faster then the init field of a unit. But hey new stuff learned - CHECK :D Share this post Link to post Share on other sites
