actionscript 3 - how does the "for each in" loop work? -


for reason code not work intended, i've cut out of program but, think need tell have tree array, , trying make collisions said trees thought work:

function collisions(loopevent:event):void {     each (var a:tree in treearray)     {         if (brettmc.right1.hittestobject(a.stump))         {             rightcoll = false;         }         else         {             rightcoll = true;         }          if (brettmc.left1.hittestobject(a.stump))         {             leftcoll = false;         }         else         {             leftcoll = true;         }          if (brettmc.up1.hittestobject(a.stump))         {             upcoll = false;         }         else         {             upcoll = true;         }          if (brettmc.down1.hittestobject(a.stump))         {             downcoll = false;         }         else         {             downcoll = true;         }     } }

i pretty sure problem for each loop messed up.

i don't see issue loop itself

except

is treearray actual name of variable? or it's type?

if that's actual variable, can trace length of before loop?
