It is possible to make RPG's with AGS; but you will need some coding experience.

Firstly, I should say that there are many ways to script RPG's with AGS. I will tell the way I use while I was developing Asporia: Hidden Threat in this tutorial (all the screenshots are from the source code of the game.)

Let's prepare our GUI where we can learn how many health, mana and exp. we have.

So the variables in the game should have been displayed in the GUI.

If an enemy can attack you, then you should be able to die in the game. Type this scripts in the repeatedly_execute section:

Wait(40);
NewRoom(28);

The room 28 is the "Game Over" screen. You should also use the scripts in Players Enters Screen (before fadein)

'''Level Up:'''
==Level Up:==


You can level up in the game after you have a definite exp. points. For example in the repeatedly_execute section:

''if (GetGlobalInt(4)>=60) {

Display("You leveled up and gained the magics of Cure +2, Fireball +2 and 6 mana points .");
 
''Display("You leveled up and gained the magics of Cure +2, Fireball +2 and 6 mana points .");''
 
''AddInventory(10);''


AddInventory(10);
''AddInventory(11);''
AddInventory(11);
LoseInventory(4); //losing the old Cure +1 magic


SetGlobalInt(2,GetGlobalInt(2)+6);
''LoseInventory(4); //losing the old Cure +1 magic''
}''
 
''SetGlobalInt(2,GetGlobalInt(2)+6);''
''}''


The player will gain some new magics. Sure, you can use your own scripts for level up.

Different Endings:'''

You may also want to add different endings which is according on the player's decision in the game. For this, add this code to game_start:

The room 62 leads you to the good ending in the game. And the room 57 is to another ending which isn't good...

If you think your game may be found too hard by some players, then you can add some cheats. To on_key_press;
