Scoring System -- How would I set it up?

[PerylDemise]

ok. Reposting, sorry. For my scoring system, on a dart board.

My dart is an oval *graphic form* and the dart board is in graphic form too. How would I calculate the distance between the two of them?

Would I use the distance formula? :

distance := sqrt[(x2-y2)-(x1-y1)]

If I do, then what goes into each of the variables?
Would the x1 and y1 be the co-ordinates of my dart or the center of the dart board, or something else?

each of your x/y pairs are the coordinates of point. two pairs, two points, one distance between them

[PerylDemise]

ok. But for the first set of co-ordinates (x1 and y1), would I get them from the dart that's randomly placed on the screen and then the other two (x2 and y2) come from the dart board position? ^^; Or would it be the opposite?

It doesn't matter, because it finds the distance, not the displacement.

Also, save yourself the trouble of creating a function for this, or implementing the forumula some other way. Use the Math.Distance (x1, y1, x2, y2 : int) : int function.

Wow. Thank you ;D That helped a lot. :3 The point system seems to be working now

Another quick question though. I have a function set up but I forget how to call upon it within the body of the code. Can anyone help on that part? ^^;

code:

yourVariable := yourFunction (yourParameters)

Or like

code:

put yourFunction (yourParameters)

Or something like that. You get that the above is just generally. Whether you store the result in a variable or display it right away is up to you.

Don't forget that in functions using more than one parameters, to call it with all the parameters specified.

code:

var tempProduct : int function getProduct (i, c : int) : int     result i * c end getProduct for i : 1 .. 5     for c : 4 .. 6         put getProduct (i, c)         %or         tempProduct := getProduct (i, c)     end for end for

Thank you so much ;D This has been a lot of help :3
