friendly.

After wanting some typewriter text for my game (so the text gradually 
appears one letter at a time) I did some searching for a tutorial and 
quickly found every example I came across was encased in a bunch of RPG 
'extras' such as dialogue boxes and multiple answers. All I wanted was 
the bare-bones and after a bit of trial and error it turns out it's 
pretty damn easy.

So first of all you'll need to create an object that will be responsible
for writing the text on screen. Inside the object's Create Event add the
following:

Create Event Code:

    vText = "Show Me"; //This is the text we want to display
    iText = 0; //This variable controls how many letters are currently shown (e.g. if iText = 8 then the first 8 letters of vText will be shown
    alarm[0] = 1; //Here we set the whole script in motion


In the object's alarm[0] event add the following:

Alarm0 Event Code:

    //We use an if statement here so the alarm stops once the full text is displayed
    if iText <= string_length(vText)
    {
      iText += 1; //Here we simply add 1 to iText to show one extra letter
      alarm[0] = 10; //This controls how fast the text is written. Increase this if you want it slower
    }


And finally we need to show the text, so in the object's Draw event add 
the following:

Draw Event Code:

    draw_text(x,y,string_copy(vText,1,iText));


And there you have it, job done!

Currently that will only display a single text string, however it's very
easy to modify it so you can have a single object control many different
strings. The obvious examples for this would be a dialogue or an 
inventory screen where the text is changed based on the highlighted 
item. In these cases all you would need to do is change the vText to the
new text, reset the iText back to 0 and restart the alarm[0].
