Introduction
In this tutorial, I will show you how to make dynamic dialog-based tutorial system.
What is it?
It's a message box dialog, which title and content updates dynamically through the usage of arrays. It consists of two buttons which is Next and Previous.
Why it's needed?
It's needed for time consuming and code optimization.
So, let's get started now. Please note that I'll be explaining most of the things in comments if I haven't did on normal text. First of all, put this on top of your script(usually the place where you write the constants).
As you can see that I've wrote only 1 dialog because it will be updated dynamically. Now, go to the place where you declare your variables and put this under your variables.
As I mentioned earlier, that the comments will explain you everything you need to know. Now, what we are going to do is to show the dialog. So, put this anywhere you like which will show the tutorials dialog to the player.
The tutorialindex variable is used to determine which tutorial to be shown to the player with the help of player addressing. Now go to the OnDialogResponse callback and inside the block put this code.
If you have any question, please post below so I can help you.

{

else tutorialindex[playerid] = 0; // If it's less than 0 then we will set the tutorial index to 0 because the value cannot be negative as it starts from 0.
ShowPlayerDialog(playerid, DIALOG_TUTORIALS, DIALOG_STYLE_MSGBOX, tData[tutorialindex[playerid]][title], tData[tutorialindex[playerid]][content], "Previous", "Next"); // Then he will be shown the dialog with the previous tutorial as you can see on the index.
}
else // If next button has been clicked
{
if(tutorialindex[playerid] >= (sizeof(tData))-1) //This checks to see if the tutorial index is greater or equals to the maxmium number of tutorials which means that the player has finished watching all the tutorials.
{
//After player finish the tutorial, the code here will run.
}
else //If he is not yet finish the tutorial
{
tutorialindex[playerid]++; // Increase their tutorial index.
ShowPlayerDialog(playerid, DIALOG_TUTORIALS, DIALOG_STYLE_MSGBOX, tData[tutorialindex[playerid]][title], tData[tutorialindex[playerid]][content], "Previous", "Next"); // Then he will be shown the dialog with the next tutorial as you can see on the index.
