Overview

Sphere is a 2D RPG engine, in development since 1997. It allows
people with not much programming experience to create role-playing
games like Final Fantasy VI or Phantasy Star.

Sphere provides a graphics rendering system that supports 32-bit color.
That’s 16.7 million colors and 256 levels of translucency for every pixel
on your screen! It even allows for hardware acceleration for those of you
with 3D accelerators! Sphere can also load PNG, JPEG, PCX, BMP, TGA, and GIF
images. For sound, Sphere uses Audiere,
which means it can play Ogg Vorbis, MP3, WAV, IT, XM, S3M, and MOD files.

It also supports the three standard modes of input for games:
keyboard, mouse, and joystick.

Sphere uses SpiderMonkey
(Mozilla‘s
JavaScript
implementation) for scripting. JavaScript is a very powerful, easy, and
flexible language.

Engine

The core Sphere engine, after being installed, can run several games.
This means that the games don’t have to be distributed with the engine,
saving download time and disk space. Also, the games can be run on other
operating systems, such as Linux, if the engine runs there. On the other
hand, you can include the Sphere engine with your game so that Windows
users can run your game out of the box.

The Sphere engine is based around maps. Maps use tilesets, which are
collections of tiles. A map of a beach would have tiles that represent
the sand, the water, clouds, signs, and anything else on the beach. Sphere
has support for animated tiles. Torches could flicker in a cave, or waves
could lap at the shore. Maps support unlimited layers, each with parallax
and automatic scrolling.

Objects in Sphere are represented as entities. Townspeople are defined with
spritesets, which are collections of frames. People can walk in eight
directions, and have special directions (usually used for emotions or
running). Unlike most RPG engines, spritesets in Sphere have a variable
size. Large animal spritesets are used just as easily as people.

Editor

Sphere comes with an integrated environment for editing maps, spritesets,
scripts, fonts, etc. You can even play your game’s music and sound effects
while you work.
