Lingo: Boolean Logic & Big Cursor READING: Manual pages of the commands described here File "arttest.dir"System cursors are cool, but very restricted in size and color. What if you want to have your very own cursor, colorful and big (like a pencil that you would use in order to take a multiple choice test)? You can simulate such a cursor by having a cast member "stick" to the tip of the cursor after hiding the system cursor. For more realistic impression we can offset the simulated cursor (like the pencil we mentioned). First you have to hide the regular cursor temporarily. on startMovie global result result = 0 cursor 200 -- hide cursor so that the tip of the pencil becomes the cursor end on stopMovie cursor -1 -- back to mouse pointer end Now, while you are at that frame, you can have your own cursor follow the mouse - like with the cursor chase example. But for simulating a pencil there is a catch: You want to check the checkboxes with the answers with the tip of the pencil. But the locV and locH will give you the coordinates of the registration point. So, you need to offset the pencil so that the cursor is at its lower left corner. --HandleChase: on HandleChase -- sprite 8 is the pencil. sprite(8).locH = the mouseH + 60 -- push pencil to the right sprite(8).locV = the mouseV - 75 -- and up, so it is at the tip of the mouse end HandleChase
To find the exact coordinates, select the mouse cursor and check the difference between registration point and lower left corner of the enclosing rectangle, that is, between X and L(eft), and Y and B(ottom) in the sprite properties. Boolean LogicThe application as it standschecks the correctness of Q1 on the test. To see if a checkbox is selected, you test to see if its hilite property is true. This can be done in an if-statement:
on mouseUp
if member(14).hilite then
alert "good job"
else
alert "you fail"
end if
end
This is not correct, though: Only answer a (member 15) is correct and should be checked. The other two answers (members 16 and 17) should not be checked for the first question to get the "good job" comment. Q How would you correct the code to evaluate correctly the first question? Q. Create checkbox responses for the other two questions. Then augment the code so that it evaluates all three questions of the exam.
