GML Help with typewriter effect bug, please!

[Edwin]

Hey, people. I have a simple typewriter effect for my text but it's lagging after the line break. How I can fix it?
Code:

/// Create Event
message = "Hello, World! This is my typewriter effect test!";
count = 0;

// Step Event
if (count < string_length(message)) {
    count ++;
}

// Draw Event
draw_text_ext(x, y, string_copy(message, 0, count), 20, 200);

So all I know it's happening because the width of draw_text_ext is not proportional to the room size. How can I fix it?

I would do it this way:

// Create Event
message = "Hello, World! This is my typewriter effect test!";
message_final = "";
count = 1;
type_delay = room_speed/4;
alarm[0] = type_delay;

// Alarm 0 Event
if (string_length(message_final) < string_length(message)) {
   // Get the char at count index
   var char = string_char_at(message, count);

  // Add the char to the final message
  message_final += char;

   // Increment count
   count++;

   // Reset the alarm
   alarm[0] = type_delay;
}


// Draw Event
draw_text(x, y, message_final);

I think you didn't understand my question, but thanks for this example.

It is normal, if while writing a word and this is passed the limit, this goes to the next line.
What you can do is separate the line breaks beforehand

message = "Hello, World! This is my#typewriter effect test!" ///use # to separate

or

message = "Hello, World! This is my
typewriter effect test!"
