1. Events: mouseUp, mouseDown.

2. Normally this is placed in either a sprite script or a cast script. If the button has different reactions in different frames, then place the script in the sprite. If the button always reacts the same way (or is used only in one frame), then put the script in the cast.

3. Example:

   		on mouseUp
   			go to frame "part 2"
   		end
   

1. To get information from a field, use a script like:

   put field "Name" into theName

   where theName is either a local or global variable. You could also store the value in a field into another field.

2. You can also get information as soon as it is entered into the field by using a on keyUp handler that is placed in either the sprite or cast script for the field. In this case you should test for a specific key, like the RETURN key.

3. To determine which key was hit by the user, use the function the key which returns the value of the last key entered.

4. Example:

   		on keyUp
   			global theName
   
   			if the key = RETURN then	
   				put field "Name Entry" into theName
   			end if
   		end keyUp
   

		if the hilite of member "Choose Option" = TRUE then
			go to frame "new sequence"
		end if

1. Do this with the "rollover(x)" function.

2. Normally this is placed in an exitFrame script.

   		on exitFrame
   			if rollover(1) then go to frame "Left"
   			if rollover(2) then go to frame "Right"
   		end
   

1. You can use built in cursors or custom cursors that you make yourself.

2. 2. If you use a custom cursor, it must be 1-bit and must be no larger than 16X16 pixels.

3. Example:

   		on exitFrame
   			if rollover(1) then
   				cursor [3]
   			else 
   				cursor -1
   		end
   

4. Note that using a number without brackets in the cursor command will cause director to use a built-in cursor. Using a number in brackets will cause director to look in that numbered cast member.

5. Since a cursor is 1-bit, it is either black or white. White areas will appear transparent on the stage. To make them opaque, you must create a mask. The mask looks exactly like the cursor, except it is black in the areas that you want to appear opaque.

6. Example:

   		on exitFrame
   			if rollover(1) then
   				cursor [3,4]
   			else 
   				cursor -1
   		end
   

7. In this example, the cursor is in cast member 3, the mask in cast member 4.

To create a custom cursor (which I assume is in sprite 5), follow the two steps below:

1. make the normal cursor invisible and make your sprite a puppet. You could do this in the movie script:

   	on startMovie
   		set the puppet of sprite 5 to TRUE
   		cursor 200
   	end
   

2. Now make your custom cursor follow the old cursor by calling the user-defined handler doArrow . We'll define this handler in a minute.

   	on exitFrame
   		doArrow
   		go to the Frame
   	end
   

3. In this case you must create the handler doArrow . Put this in the movie script:

   	on doArrow
   		set the locH of sprite 5 to the mouseH
   		set the locV of sprite 5 to the mouseV
   		updateStage
   	end
   

1. You will use the keyUp handler to achieve this interactivity.

2. Often it is best to use a primary event handler to catch this message. For example, the keyUpScript and keyDownScript are good places to catch a keystroke that you want to always be caught in the movie.

3. Example:

   		on startMovie
   			set the keyUpScript to "checkForTab"
   		end
   
   		on checkForTab
   			if the key = TAB go next
   		end
   

   the checkForArrow is a name of a handler that you must place in the movie script.

4. Primary event handlers are tricky to program.

5. As an alternative, you can catch the key stroke in a movie script. This is easier to program. Since the movie script is at the top of the message hierarchy, a key stroke will always be caught.

6. Example: in a movie script put the following:

   	on keyUp
   		if the key = TAB then go next
   	end
   

   7. Note that the TAB used here is a predefined constant. That means that director already knows about it....you don't have to assign a value to it. The predefined constants in director a re:

   	BACKSPACE	EMPTY	ENTER	FALSE	QUOTE
   
   	RETURN		TAB		TRUE
   

   8. To check for any other character, youÕll have to know its ASCII encoding.

1. To make a sprite moveable, you can either check its moveable box in the score, or you can make it moveable via Lingo.

2. If you use Lingo, you must determine in which frames the sprite will be moved. If it is to be moved in all frames in the movie, make it moveable in the startMovie script:

   		on startMovie
   			set the moveableSprite of sprite 2 to TRUE
   		end
   

3. If the sprite is only to be moved in a particular frame, make it moveable when you enter the frame and unmovable when you exit:

   		on enterFrame
   			set the moveableSprite of sprite 2 to TRUE
   		end
   
   		on exitFrame
   			set the moveableSprite of sprite 2 to FALSE
   		end
   

4. You can then determine whether the user has moved the sprite over another sprite using either the intersects or the within tests.

5. Example:

   	on exitFrame
   		if sprite 2 intersects 4 then go to frame ÒanimateÓ
   	end
   

1. There are two parts to this. First, you must create the menu. This can be done anywhere. If you want the menu to last the whole movie, put it in the startMovie script. If you want the menu only to be present in a particular frame, put it in the enterFrame script.

2. To create the menu use the installMenu command:

   	on startMovie
   		installMenu 17
   	end
   

   where 17 is the number of the field cast member that contains the menu's items and their definitions. Note that you must use the cast number, not a name.

3. You must create a field and place the information for the menu in the field. For example, the field in cast 17 might contain the information:

   	menu:Volume
   	Loud|go to frame "Loud"
   	Medium|go to frame "Medium"
   	Soft|to to frame "Soft"
   

4. You can put more than one menu into a menubar.

5. You remove a menu with the command:

   	on startMovie
   		installMenu 0
   	end
   

	if boolean-expression then
		some Lingo commands
	else
		some other Lingo commands
	end if

1. You test the value when the user hits the return key. In this case, you could put a

2. You loop in the frame, testing the value in the field each time you exit the loop.

1. Repeat structures. Repeat structures can be used for many different effects in Lingo. Remember that other types of interactivity cannot
2. One example: printing the mouse location.

3. Controlling sound.

4. Controlling the tempo.

5. Playing Video.

6. Controlling palettes.
