[Intermediate and Scriptless] How to make an inventory/menu with events only

じ☆ve冰风

This tutorial will show you how to make event based interface without requiring any scripting.

Disclamer: Will  not provide any graphic to base on.

Requirements: Paint.net (or any other image editor that supports transparency).

1. Preparations.
First before starting, you will need to have an idea of what you want in your inventory/menu, if your game is multi-language hardcoded, don't forget to take this into consideration. Also don't forget to disable the default menus via an event at fist occasion.

2. Interaction allowance.
You might want to prevent the player to accessing the menu during a specific moment during your game. Create a switch that if enabled, will prevent the menu to open, I personally called it 'menu_lock'. Create another one called 'inv_is_open'. Go in common event create one named 'menu.aviability' and insert the following and create empty common event if needed:

Now create an event on any of your game map that you want and do the following:

Once done, copy the event to all maps that you want your menu to be accesible.

3. Menu background and text.
Create a background to go with your menu; include text in it if it is not flexible (cannot be affected in any way by the gamne state). If you didn't knew already, an RPG Maker VX Ace game default dimensions are 544 x 416. If you want to replicate the default RTP font follow the following steps:
This method is for Paint.net only.
1. Write in white in Verdana size:14.
2. Create a shadow under it. (Duplicate that is fully blackened with the saturation effect).
3. Photo glow with values: 1, -100 -100
4. Create 5 layer duplicate (with first, 6 layers shadow layer total)

Once you have designed your menu background, it is time for "flexible" text, create multiple images with the value changed, oif there is alot of possible values (like stats), consider creating base text (exemple: Your attack level is: ) and then create individuals image that contain the digit 0 to 9.

You will also need to create a cursor, there is two way of creating a cursor image: Eitheir you create a fixed image size and make the cursor move position in relation to the possble cursor slot or just makeone cursor picture (simpler - especially if you are going to go for a complex menu).

4. Graphic display.
Go to your 'inv.handler.open' common event and insert the following:

Now in the common event 'inv.handler.cursor' this where you will need to set where the cursor will go for each selectable thing in your menu. Exemple:

Create multiple conditonal branches according to your needs.

5. Cursor updating and button press.
Now we need to get the cursor to move and update its position. In the common event 'inv.handler' you will need to insert the player arrow keys input. Here's an example:

If you want to make a save/load game function here some script call to help you:
Spoiler: Save game (script call)

                Code:        

复制

if DataManager.load_game(0)
  $game_system.on_after_load
  SceneManager.goto(Scene_Map)
End

Spoiler: Check if savegame exist[quote]                 Code:

I hope this tutorial helped you to understand the basic on how to make event-based interfaces. If you have trouble making the player to stop while the interface is open, make a common event to change the tileset or get a script that allow you to prevent the player to walk if a switch is on.
