System Requirements
- Unity 2018.4 or later
Dependencies
- UnityOctree (as git submodule)
- Unity-Reorderable-List (as git submodule)
- PiscesConfigLoader (optional, separately installed dependency)
Installation
- Clone into the Assets folder of your Unity project
git clone [email protected]:SolAnna7/TaurusDungeonGenerator.git
cd TaurusDungeonGenerator/
git submodule update --init --recursive
-
Download from Unity Asset Store - To load the dungeon structures from config files use the PiscesConfigLoader
Usage
Create your room assets
- Add the
Roomcomponent to the root - Setup your doors with
RoomConnectorcomponent - Collect your rooms into
RoomCollection-s for randomized usage
Define your dungeon structure
- In code

Parameterise and generate your dungeon, then build it in unity space
PrototypeDungeonGenerator generator = new PrototypeDungeonGenerator(inputStructure,
seed,
new PrototypeDungeonGenerator.GenerationParameters {RequiredOptionalEndpointNumber = optionalPathNumber});
PrototypeDungeon prototypeDungeon = generator.BuildPrototype();
DungeonStructure builtStructure = prototypeDungeon.BuildDungeonInUnitySpace(transform);
🎆🎆🎆 Profit 🎆🎆🎆
Nested Dungeons
Reuse dungeons as subtrees Can continue with children Can be defined as global (used from any other dungeon) or inline (reusable only in one main dungeon)
example-dungeons:
global-nestable-dungeon:
start-node:
connection: DungeonGenerationTest/Corridors
length: 1_3
subs:
- node: DungeonGenerationTest/MiddleRoom
nesting-presentation:
start-node:
node: DungeonGenerationTest/EndRoom
subs:
- connection: DungeonGenerationTest/Corridors
length: 10_20
subs:
- node: DungeonGenerationTest/CorrX
subs:
# this nested dungeon continues have child nodes
- nested: example-dungeons.global-nestable-dungeon
subs:
- connection: DungeonGenerationTest/Corridors
length: 1_3
subs:
- node: DungeonGenerationTest/EndRoom
- nested: example-dungeons.global-nestable-dungeon
Branches
After creating the main tree, other low priority paths can be added. This can be used as a way to add complexity and dead-ends to a dungeon.
The brances are defined as nested dungeons (global or inline)
Set the maximum number of unused connectors where brances are tried to be generated. Either as percent branch-max-percent: 50 or as a number branch-max-num: 12
realistic-dungeon-layout-1:
inline-nested:
# branch type 1 definition
inline-branch-1:
start-node:
connection: DungeonGenerationTest/Corridors
length: 4_7
subs:
- node: DungeonGenerationTest/MiddleRoom
# branch type 2 definition
inline-branch-2:
start-node:
connection: DungeonGenerationTest/Corridors
length: 2_5
subs:
- node: DungeonGenerationTest/CorrX
# the types of dungeons used as branches
branch-prototypes:
- inline-branch-1
- inline-branch-2
# maximum percentage of empty connections where branches will be built
branch-max-percent: 50
...
Optional paths
Some subtrees of the main path can be marked as optional and nodes inside them as optional-end. At generation the required number of optional endpoints can be set. Use-Case: Reusing the same dungeon with different number of exits.
Margin between elements
Add additional margin between elements This is still an experimental feature
structure.StructureMetaData.MarginUnit = 0.5f;
Debug view
Use the DungeonDebugger static class to
- Draw in-editor gizmos around the dungeon element with color coded information
- Generate a debug structure using unity cubes with the same colors
- Generate debug description text
Planned features
v0.9
- Room repetition control
- Path straightness/
gaynesscurvedness control
v1.0
- Unity Editor extension for dungeon structure creation
?
- Optional handling refactor: Activate optional paths based on room tags
- Circles in the layout
- Variables: Define variables (like random ranges) to reuse in the structure
- Bounding box for the dungeon
