<p>the "Distance to" integer function will now drag to "if true", but it generates the code line:</p>
<p> </p>
<p> if penguin distanceTo flagpole</p>
<p> </p>
<p>and does not give the user a choice of logic comparisons that dragging an integer variable would. The desired line should read:</p>
<p> </p>
<p> if penguin distanceTo flagpole < 1</p>
<p> </p>
<p>I will create a simple version of the a2w world that shows the problem.</p>
<p> </p>
<p>When I clicked on the Outermost arrow next to the flagpole it indicated an error. Here is the stack trace for the error:</p>
