Welcome to this tutorial!
In this, i will teach you how to create better dialogues through cutscenes, timeouts and color codes.

I: How long dialogues should start
First of all, a dialogue may start (notice may, you can start it with a timeout instead) using a cutscene.
Dialogues usually last for 5-10 seconds depending on how long the actors' speeches are.
I make dialogues last usually 7 or 5 seconds.

II: How the camera is facing the actor
To give the actors a "thrilling" view, the camera should face the actor very near or sideways.
To give them a regular view face the camera in such a way that it can see the torso, but not the legs.

III: How to write a very good dialogue
Dialogues are more effective when there are plenty of actors the camera is facing at, and you don't know who's saying the speeches.
I write dialogues using this code:

(~b~(r if he/she is an enemy, g if he/she is a friend and y if he/she is neutral.)Actor's Name Here~w~)
Dialogue here

If in case you didn't understand, here's an example

(~r~Terrorist~w~) Get down here, you fool!

In case you don't know, those ~ are codes which you can use to color the words.
To color the word "CJ" blue, here is the code

~b~CJ~w~

I did say the word "CJ" ONLY, right?
If you want all words colored blue, remove the ~w~

Here is an example of making words with different colors

~g~Good~r~Bad~y~Neither

If you want to add more words add another tag and if you want the next words to become white just add ~w~

Here are the most common colors i use:

~g~: Green
~w~: White (Default color)
~b~: Blue
~y~: Yellow
~p~: Pink

There are lots more, but i don't use them.

IV: Finishing your dialogue
Checking should be done after finishing the dialogues.
Here is an example of a cutscene dialogue:

Camera facing quite near and sideways at the actor
Length: 6 seconds
Text: (~b~CJ~w~) You'll be the first one i'll get, watch your back, kid.

Thanks for reading my tutorial.
I'll make a mission about this soon.
