[GM]Array Tutorial, Game Maker, or anything with C scripting Options

[Rukiri]

This tutorial will cover arrays, I'm basically going to show you how to right a menu system using arrays. Of course, this is just text, not the menu itself. "Think I'd give you that much code?"

Variables:

selected = 1; // Option selected
page = 0; // in 2D arrays it's wise to create a variable for the page number.

Array:

menu[0,0] = 3; // The max options for the array
menu[0,1] = "Stats";
menu[0,2] = "Save";
menu[0,3] = "Quit";

Drawing the array:

for (i=0; i<=menu[page,0]; i+=1)
{
draw_text(x,y+(i*16)-16,string(menu[page,i]
}

If you want to color your text, for the selected option, just use a simple method like this.

if (selected = i)
{
draw_set_color(c_aqua);
}
else
{
draw_set_color(c_white);
}

^. Place above draw_text.

Example of such a menu:

That is a very good example. I usaully do my menus differently, but your way takes a lot less code, not to mention uses arrays. This also gave me an idea of something I can do in C#.

Huh, I never really thought of using an array for the menu. Although I've never really tried to make one before anyway, so I dunno what I would have come up with.

Nice idea, nice tutorial!

Arrays in various languages:

CODE

# C++
int myNumbers[100]

# Pascal
myNumbers :array[0..10] of integer

# Ruby
myNumbers = [ ]

# Java
I really don't know. Learning java, still a big noob.
