I have provided some blocks that you will need in to implement the game. You will need to fill in the body of these loops and conditionals. Additionally you will need to think about how to combine all of the loops and conditionals so that your game of Tag executes properly&#xD;&#xD;The basic control flow for Foo is like this:&#xD;Do the following forever:&#xD; if the game is not frozen:&#xD; if Foo is the runner:&#xD; point and move towards Bar&#xD; if on edge bounc&#xD; otherwise:&#xD; move forward&#xD; if a random number between 1 and 40 = 20&#xD; point in a random direction&#xD; if on edge bounce&#xD; &#xD; If Foo is chasing Bar and Foo is touching Bar:&#xD; Go to a random position&#xD; Change it so that Bar is now chasing Foo&#xD; Increase Foo&apos;s number of tags by 1&#xD; &#xD;&#xD;We have created two variables for you: frozen, and Foo Runner. Frozen is meant to keep track of whether the game is frozen or not. The sprites should only be able to move if the game is not frozen. Pressing the spaebar should switch whether the game is frozen or not. &#xD;&#xD;The other variable, Foo Runner, keeps track of whose turn it is to chase. If it&apos;s true then Foo will chase Bar; otherwise Bar will chase Foo.&#xD;&#xD;&#xD;You may want to create another variable or two – what do you think that is? </comment><script x=”18″ y=”60″><block s=”receiveGo”></block><block s=”doForever”><script></script><comment w=”268″ collapsed=”false”>Main loop with the instructions for playing the game of tag.</comment></block></script></scripts></sprite><sprite name=”Bar” idx=”2″ x=”24.856459330143455″ y=”-152.56937799043064″ heading=”90″ scale=”1″ volume=”100″ pan=”0″ rotation=”1″ draggable=”true” costume=”0″ color=”96.9,193.8,0,1″ pen=”tip” id=”33″><costumes><list struct=”atomic” id=”34″></list></costumes><sounds><list struct=”atomic” id=”35″></list></sounds><blocks></blocks><variables></variables><scripts><script x=”20″ y=”20″><block s=”receiveGo”></block><block s=”doForever”><script></script><comment w=”404″ collapsed=”false”>Main loop with the instructions for playing the game of tag.</comment></block></script><script x=”20″ y=”112″><block s=”doIf”><block s=”reportNot”><block var=”frozen”/></block><script></script><comment w=”347″ collapsed=”false”>If the game is frozen, we do nothing.
