Using rows to make advanced menus

[Hblade]

Hey guys its me again and I found a way to make advanced menus by using rows. First, make 2 variables called rowx and rowy, now make an actor, (preferd half the size of the window your selections are in... before I get started let me explain what this does. Look at this screenshot

Now, before we get started, you need to know how many rows your selection has, for example mine had 2 rows x, and 4 rows y, so you have to make sure that you dont set too many or too less rows.

Now that you have your rows memoriesed, let me go over this code with you
When down is pressed

Code: Select all

rowy++;
if (rowy == 4)
{
    rowy = 0;
    y = y - 20*4;
}
y = y + 20;


The first part,

Code: Select all

if (rowy == 4);

tells the program that when it's at the botom of the selection, it resets the rows to 0. (Mine is 4 rows y, so I used 4.), The second part, y = y - 20*4, again remember that my max rows are 4, so if you have 5 rows, you'd say y = y - 20*5;.

But wait, whats the 20 for?
The 20 is my text's height, play around with the numbers untill you get your text's size.

What about left and right?
Left and right are the same thing, I'll go over the code for the left and right, too.

Code: Select all

rowx++;
if (rowx == 2)
{
    rowx = 0;
    x = x - 306 * 2;
}
x = x + 306;


My max rows x is 2, so I used 2.

But wait, whats the 306 for?
The 306 is half the width of the menu that holds my selections, this is so it matches the widnow perfectly.
