Concept

This is an attempt to replicate the structure of the Sphere Grid from the HD version of Final Fantasy X using Unity.

Its development attempted to create a flexible structure that would enable replicating the original Sphere Grid, as well as create entirely new ones. I also attempted to replicate the original lighting and visual effects using URP and ShaderGraph.

​

Structure

This sphere grid is structured in such a way that each Node is placed within a Core. Nodes are addressed within cores using an adaptation of the polar coordinate system, using a radius (distance from center) and an angle, as shown in the scheme below

​

 

Once placed in a Core, two adjacent nodes can be connected, as long as they have the same radius or same angle. Center nodes can be connected to any node of a superior radius.

​

Lighting and visuals

The lighting and visual effects were replicated using Unity's URP, namely the 2D Lighting system, as well as ShaderGraph.

​

The system uses different types of glows to indicate interactivity:

  • The Target marker controlled by the player glows white around the selected node;

  • The Character marker indicates the current node position of the character and glows in their own specific color; it also illuminates neighboring nodes;

  • When attempting to move, nodes within movable range also glow in the same color as character and opposite frequency.

The lines connecting nodes are also rendered using a shader. Lines have an inherent watter ripple effect.

  • Inactive lines are colored gray;

  • Active lines are colored in the character's color.

  • A line's filling is defined from 0 (inactive) to 1 (active) and is animated accordingly when selected.
