<desc>Works like <emlink href="script/fn/PathFree.html">PathFree</emlink>, but instead returns an array containing the coordinates of the first solid pixel found on line. Returns nil if the path is free.</desc>
<remark>All coordinates are global, even in local calls.</remark>
<examples>
<example>
<code>var x = <funclink>Random</funclink>(<funclink>LandscapeWidth</funclink>()),
pos = PathFree2(x, 0, x, <funclink>LandscapeHeight</funclink>());
if(pos)
<funclink>CreateObject</funclink>(Idol, pos[0], pos[1]);
</code>
<text>Creates an Idol somewhere on the surface of the landscape.</text>
