[VXA] Call Scene from Items & Skills

Call Scene from Items & Skills
Version: 1.0
Author: modern algebra
Date: February 5, 2012

Version History

• <Version 1.0> 2012.02.05 - Original Release

Description

This script allows you to call a scene directly after using an item or skill. While it is always available simply to call a common event and call the scene from that, this script allows it to happen directly without going back to the map, so that when the scene is exited, it goes straight back to the scene that called it. In that regard, the script doesn't add functionality so much as it simply makes it smoother to call a scene from an item or skill in the menu.

Naturally, this script will not work if the item or skill also calls a common event. In that event, you can just simply call the scene out of the common event.

Please note that this script does not work in battle and is not intended to work in battle since, generally speaking, you do not want the player to be able to escape the battle by calling a scene. Besides, you can use common events in battles directly.

Features

• Allows you to directly call scenes from using an item or skill in the Item or Skill menu
• When you exit the scene, it will take you back to the item or skill scene from which it was called

Instructions

Paste this script into its own slot in the Script Editor, above Main but below Materials.

To have an item or skill call a scene, just place the following code into its notebox:

      \scene[Scene_Name]

Where Scene_Name is the name of the scene you want to call.

Examples

• \scene[Scene_Debug]
      When used, the item would call the Debug Scene.
• \scene[Scene_MonsterCatalogue]
      If you are using my Monster Catalogue, it would open that scene.
• \scene[Scene_StateView]
      If you are using my State Viewer script, it would open that scene.

#
#    Note that this script does not work in battle. If you want to call a scene
#   from battle, do it with a common event.
#
#    Note that if you set an item to call a scene like this, then any common
#   event assigned to the item will be prevented from running (if in the menu).
#   If in battle, on the other hand, this script is inoperative and so the
#   common event will be run.

Known Compatibility Issues

No compatibility issues have yet been brought to my attention.

Thanks Modern, I had a world map in my inventory and so with this it won't exit the item menu.

Delivering as always, Modern 

Aha, so you made it. Great. As soon as I get some time, I'll give it a try.

Is it possible to call the crafting scene with bubble's script, when it specifies the category of the item you want to craft? For example, I have a recipebook that has category "armors", now, with bubble's script, you can specify the scene to show up only the recipes with the armors category.
When I try to specify this in the skill's notebox i get an error.
http://mrbubblewand.wordpress.com/rgss3/tactics-ogre-psp-crafting-system/ This is bubble's script.
Thanks

No, it's not possible to pass an argument like that in this script.

you could add notetags <scene_prepare: x, y, z>
grab them. and do the scenemanager.scene.prepare(x,y,z) ONLY if the note exist.
i do that technique in one of the script i'm making.
