Setup

Setting up Breakable Walls FX is really simple, just follow these steps:

• Select a wall or flat surface from your game.

• Add the BreakableWall.cs as a new component.

• Configure the optional parameters of the script.

Thats it! Now the wall is fragmented and is ready to be destroyed, this could be done either by explosions like its done in the demo scene or in more programatic ways.

How it works

The BreakableWall.cs is the main script of the project. It

This script works in 3 steps:

• It first creates a voronoi diagram of the same bounds as the wall or plane its on. This is done using the open source library csDelaunay that is included in the Plugins/Voronoi/ folder.

• The script then iterates through all the voronoi regions of the diagram and for each one of them created a new mesh with the bounds of the region and the depth of the wall. Effectively subdiving the wall into “shards” or “pieces”. Each of these “shards” contains the correct UV coordinates and size making the texture look seamless and making the group of shard look identical to the original wall.

• After this procedure the original wall is disabled and its replaced by the newly generated, breakable wall.

Misc

The script is pretty extensible and since the voronoi calculations are not done using Unity objects so the parallelization of these calculations can be supported easily.
