Scene_Base

This is a resource which I hope to develope to the point it is used... A lot. (wishful thinking)

At the moment what it does is allow you to create scenes, while only having to initialize the objects in the scene and writing the seperate update methods. (for interaction)

Don't forget to make the scene a sub-class of Scene_Base, ie - (class Scene_Name < Scene_Base)

In the future I hope to include introduction animation methods and closing animation methods, as well as a variety of other methods to make writing scenes easier.

The only real difference, is that when you create an object in a scene, instead of doing -

Code:

@playtime_window = Window_PlayTime.new

You'd do -

Code:

@objects['time'] = Window_PlayTime.new

And when refering to the object, you'd obviously use -

@objects['time']

as opposed to the prior.


You can also play music in the scene, simply by adding -

Code:

super('Song Name Here')

Into the scenes initialize method.

Example -

Rewritten_Scene_Menu

Code:
