Package Contests:

Procedural Generation Grid - Demo Scenes.unitypackage
Package contains example scenes, scripts and assets showing how Procedural Generation Grid can be used.

Procedural Generation Grid - Assembly Definitions.unitypackage (Supported since Unity 2017)
Assembly Definition files to speed up compilation time of your project (Fimpossible Directories will have no influence on compilation time of whole project)

__________________________________________________________________________________________

Known issues: 

Some Unity versions, around 2019.4.1 have bug which is causing FieldSetup presets to break
when trying to rename it's file or duplicate it.


If you use Unity 2018.2 or lower DEMO prefabs might be broken.
Unfortunatelly Unity does not support back compatibility for prefabs on this versions.
Since examples database is so big (258 prefabs) I can't afford another two weeks of making example assets,
so please consider using Unity 2019.4+ for demo scenes as learning version.


When Unity opens with some glitched DPI setup then Grid Painter "Paint" button and some other
GUI is not visible, I wasn't able to fix it yet. 
If you have this issue, you an fix it by clicking right mouse button 
on running Unity App Icon -> Properties -> Compatibility -> Button on the bottom about changing DPI
-> toggle on the bottom about scaling dpi -> then select System -> Restart Unity Editor -> Now all should work!
(above solution is windows only)

Description:

- Procedural Generation Grid is a system which uses grids to define fields and paths for procedural generation algorithms.

- System is designed to be flexible and able to generate very various and complex objects/places.

- It can be used to generate procedurally whole game levels at runtime or for editor use to quickly paint levels for speed up level design process.
 
- System is using something like visual scripting, so you don<6F>t need to know how to code (but you can still take benefits out of it) you just need to plan logics for your needs.

- Procedural Generation Grid is right now in Beta Stage, so many features may change, new features will come and some small elements are not fully finished but developmental stage is completed enough to be functional.
 
- Package is providing additional packages for randomly placing smaller objects in physical space using Unity<74>s collision system (Object<63>s Stamper and Pipe Generator)

Beta Version 1.5.0:
- Introducing 'Build Planner' Node Graph System:
Node Graph system will be developed until the end of Beta Version of the Plugin.
It's early version of the system, first it will aim to provide nodes and features
to replace all of the other, hard-coded generators (facility, simple dungeon, rectangle of fields etc.)
Initial version report:
> Node Graph system with more than 70 coded nodes (much more in the future)
> 6 Initial Shape Generator algorithms
> Early manual update for the node graph system
> Build Planner Executor component to handle build plans
> Function Nodes Support (functions created out of other nodes - no compilation needed)

- Field Setup Compositions for grid painters: 
Allowing to replace variables, spawned prefabs and editing other aspects of any field setup.
- GUI update for the field setup to make it a bit more compact and quicker to read with some new icons.
- Grid painters now allows to add ghost cells: no spawning in cell but trated as cell in graph, good for creating empty space inside grid.

Tile Designer allows to generate architecture tile shapes like walls, roofs, pillars
and create holes in meshes and spawn them on the scene / generate prefab without need to 
do models in the modelling software.


Beta Version 1.1.1:
- Beginner mode switch button for Field Designer Window, with just most important views to prepare FieldSetups.

- Some new unity inspector fixes
- Some smaller fixes in build plan algorithm


Beta Version 1.1.0:

- New work-in-progress components with implemented new way of generating objects, making possible
instantiating just changed cells, async computing rules logics and instantiating game objects in coroutines.

- Now "Empty" prefab spawns will be visible in scene view gizmos as green sphere
- "Empty" and some debugging gizmos now can be displayed using Grid Painter when enabling "Draw Grid with Details" Debug draw mode (grid needs to be re-generated to display gizmos)
- You can choose to inherit or no rotations of previous cell spawns under spawners advanced settings (toggle on the right of "Cell Check Mode")
- Now new added rules will be hidden inside file, so unfolding preset files contents will not display them, if needed then it can be exposed with inspector window of Modificators Pack
- If you want to keep project more clean for searching field modificators, you can use Modificators Pack buttons for hiding/exposing their visibility, or using new button visible on header of Field Modificator ("A/B" button, package needs to be inside FieldSetup / ModPack in order to see this button)
- Clicking on prefab thumbnails in the FieldModificator window will switch to spawner which is spawning the prefab
- On the Unity 2021+ the injection list in build plan wasn't working - fixed

- Some upgrades and fixes in PGG core


Beta Version 1.0.4:
- New Node + New Component: Align to Ground for placing object on ground accordingly to ground angle, very useful for placing on terrain
- New Node + New Component: Flatten Terrain for aligning Unity Terrain ground level under spawned objects
- New Node: Acquire Spawn: Mostly used for allowing /Modelling nodes to be executed without need of being added to spawner with spawning object, can be used after all spawns with "Empty" spawn
- New Node: Replace with Random Prefab: Which can be used instead of spawner's prefabs list
- New Node: Set Material Property: To change some material property on spawned object
- New Node: If World Position: Working in the same way like "Grid Position" but using world space position instead of local grid space positioning
- Node Update: Logic If Block: Added possibility to use "AND" "OR" conditions and breaking or triggering events mode
- Added buttons in spawner prefab list to automatically generate prefabs out of Model files and automatically adding colliders if not present in prefab (if you see button and press it when prefab already have some collider then no collider will be added, some prefab info just need to be updated)
- Improved some algorithms for Grid Painter component


Beta Version 1.0.3:
- New feature for copying/pasting FiledModificators by using right mouse button on "[0]" "[1]" buttons in FieldDesigner window in FieldModificators lists
- Changing Cell Size in Field Designer window should result in updated preview on the scene view
- Added "Generate" button on scene view gui for Grid Painter
- Added feature for working with "Draft" Field Setup in FieldDesigner window and exporting to file when ready
- Added option to "Copy All Properties" and "Paste All Properties" when hitting right mouse button on any rule header title (be careful, it needs to be tested to make sure everything works right)

- Added "IF Logic Block" node to call events if some conditions are met inside node
- Added "Scale Range" node for more controll over objects random scaling
- Fixed "Get / Move-Scale-Rotate" nodes GetCoordinates logics
- Fixed "Fill Rectangle" feature not filling completely area for MiniCityGenerator
- Fixed some "GetCoordinates" logics using "Cell Size" unit size and added "Run on repetition" parameter (check tooltip in unity)
- Found and fixed some issues in AnalyzeCell node


Beta Version 1.0.2:
- New Generators Feature: Now generated rooms/areas can be outlined with any field setup using "Outline Fill" option in the "Additional Options" tab
- New Generators Feature: Now generated area can be covered with any field setup using "Fill Rectangle" option in the "Additional Options" tab
Above features are NOT available for the BuildingPlanGenerator (it's old component which isn't using newest framework of PGG)

- New Node: "Transforming/Noise/" - Perlin Noise Offset and - Rotation/Scale Perlin Noise Offset
- New Node: "Modelling/" - Set Random Mesh Material

- Some node moved to the different bookmark (node: IfRotated moved to /Placement)
