Soopertree

Soopermoves

 

A game engine which supports multiplayer games (using Bluetooth) is written in Java. The games themselves are written in Soopertree. Graphics supported include 2D and 2.5D, but not 3D. A dimetric projection is used to support 2.5D graphics.

Dimetric Projection

All planes are parallel or at 90 degree angles with each other, the vantage point of the user is at a 45 degree angle, and all horizontal/vertical lines in the horizontal plane are rendered such that the slope of the line is +/- 0.5 (vertical lines in vertical planes are always vertical). Only horizontal, vertical, and diagonal lines at 45 degree angles are allowed. Since all planes are angled instead of directly facing the user due to the dimetric projection, diagonal lines are not rendered using a slope of 0.5, but have some other slope. Curves are limited to circular arcs in multiples of 45 degrees. Due to the dimetric projection they are rendered as elliptical arcs. Text is monospaced and appears skewed. Labels are allowed which contain a single line of normal text, bounded by a normal rectangle. Labels are always displayed in front of/on top of the dimetric projection.

Animation

Objects can move in 8 directions in 2D mode (90 degree angles and 45 degree angles) and 6 directions in 2.5D mode (up/down, left/right, forward/backward). Objects may include discs and balls. Support for collision detection functionality is provided. The parent object of an animated 2.5D object is assumed to be located on the ground or building directly beneath it. Objects can also dynamically change shape, incrementally or all at once.
