tile sets and CMS

Since it is midnight I will give a vague outline on how to do it, if you need further instructions I'll post more tommorrow.

1) Get/Make a Picture for your cursor, and import it
2) Determine where the first choice will be on the screen, coordinates-wise (easy enough to do, most image-editing programs give you the coordinates of where you mouse is, go from there). This will be variables [cursor X] and [cursor Y] by default.
3) Determine the distance between menu items. Assuming that all menu choices are evenly-placed, of course. Set as [cursor Y Distance] if it's just a one-collumn list.
4) Determine maximum list items[listMax]
5) Set the current cursor location, probably the first position, so [cursor position] will be 1 by default

The basic way to do this in pseudocode:

Code:

<> Declare variable [ cursor X ]
<> Declare variable [ cursor Y ]
<> Declare variable [ cursor position ] 
<> Declare variable [ cursor Y distance ]
<> Declare variable [ listmax ]

<>  ================================= 
<>  ================================= 
<>  ================================= 

<> Loop

	<> Show picture 1 at [cursor X], [cursor Y]
	<> Get keystroke, put in variable [grabbed key]
	
	<> if [grabbedkey] = up
		<> if [cursor position] > 1
			<>Subract 1 from [cursor position]
			<>Subtract [cursor Y distance] from [cursor Y]
		:End
	:End
	
	<> if [grabbedkey] = down
		<> if [cursor position] <[listmax]
			<>Add 1 to [cursor position]
			<>Add [cursor Y distance] to [cursor Y]
		:End
	:End
	
	<> if [grabbedkey] = enter
		<> Go to label "Selected"
	:End
	
	<> if [grabbedkey] = esc
		<> Go to label "Escaped"
	:End
	
<>  Comment: Ends the main loop
:End 

<>  ================================= 
<>  ================================= 
<>  ================================= 

<> Label: "Selected"
<> if [cursor position] = 1
	<> Blah
	<>
	<>
:End
<> if [cursor position] = 2
	<> Blah
	<>
	<>
:End
<>  Comment: Obviously however many items you have, you'd put here
<>Go to label "End"

<>  ================================= 
<>  ================================= 
<>  ================================= 

<> Label: "Escaped"
<> Play sound effect "Bzzt" or whatever
<> Go to label "End"

<>  ================================= 
<>  ================================= 
<>  ================================= 

<> Label: "End"
<> Basic cleanup goes here, like clearing all images,
<> clearing all relevant switches, etc

If you wanted to, you could modify that so that the cursor "loops" from top to bottom, but that's the basic idea - the cursor just jumps a set number of pixels based on your input, with limits on how far it can go in either direction, and when you select something, you jump out of the loop and process whatever you're on.
