If you're looking for more fancy editor look/dark mode, it is coming :)

1. As for linking with assimp: I'd need more details to help with this.

   You should get a regular dynamic library by compiling libassimp, with which you can link as usual. You can find many examples e.g. in CGE (we link to libraries like OpenAL, FMOD, VorbisFile, LibPng) or FPC how one can link to dynamic or static libraries.

   Note: This topic can easily get longer :), so it may make sense to move the talk to our forum ( https://forum.castle-engine.io/ ).   

2. As for other libraries:

    Well, Castle Game Engine could actually be used as a model-reading library :) One can use just `LoadNode` routine from `X3DLoad` unit to load all supported model formats ( https://castle-engine.io/creating_data_model_formats.php ). And then convert the resulting graph of nodes to whatever you need.

By default we calculate lighting per-fragment (i.e. we use Phong shading, regardless of lighting equation - Phong or physical (PBR)). This is prettier and works fast on modern systems.

However, you can request to calculate lighting per-vertex (i.e. to get more old-school Gouraud shading). This is generally uglier but more performant. To use this, toggle the `PhongShading` property inside `RenderOptions` of relevant TCastleScene to `false`. See our manual, in particular https://castle-engine.io/viewport_and_scenes , for a documentation what is TCastleScene and how to configure its properties. Note that some effects (like shadow maps or bump mapping) just cannot be realized with this Gouraud shading, so you will have to refrain from using them.

Your changelog is impressive, with very often updates. Congratulations on reaching 10k downloads!

Hello!

I assume you press "Run" (F9) from Castle Game Engine editor?

1. Make sure your FPC is detected by Castle Game Engine editor -- go to "Preferences" and then "FPC and Lazarus". It should show your FPC (either explicitly configured or auto-detected) in "FPC Path".

2. If you have FPC installed, make sure it is FPC compiler for x86_64. In particular, if you use FPC installed manually from https://sourceforge.net/projects/freepascal/files/Win32/3.2.2/ , note that this is a compiler for Win32 (i.e. 32-bit version of Windows), due to rather historical/internal reasons. You want to install version for Windows 64-bit: e.g. by adding there `fpc-3.2.2.i386-win32.cross.x86_64-win64.exe` from https://sourceforge.net/projects/freepascal/files/Win32/3.2.2/ . Or install Lazarus and FPC together from https://www.lazarus-ide.org/, Lazarus installers for Windows come with FPC for Windows 64-bit.

3. Most advised: Note that new Castle Game Engine versions actually already include a proper FPC version, for both Linux and Windows (that is able to compile for Win64). This FPC versions is also auto-detected by CGE by default.

    To try this, download Castle Game Engine from our website ( https://castle-engine.io/download ) and not itch.io. This itch.io page features a bit older version, 7.0-alpha.2. We're working now on 7.0-alpha.3 and it already features a lot of new features and improvements, the "bundled FPC" being just one of them, see https://castle-engine.io/new_features_in_castle_game_engine_7.0 . Our https://castle-engine.io/download allows to download version 7.0-alpha.snapshot, which is our latest version that is soon going to be promoted to 7.0-alpha.3.

If none of this helps, I will need a bit more information about your setup -- what is your OS (Windows, Linux?), how did you install Castle Game Engine (from this itch.io page, from https://castle-engine.io/download ), how did you install FPC. We can continue this thread here, you're also welcome to create a thread on our forum ( https://forum.castle-engine.io/ ) or make a GitHub issue. See https://castle-engine.io/talk.php for various places where to catch me :)

The engine, and your games, are written using modern Object Pascal. See https://castle-engine.io/features , https://castle-engine.io/modern_pascal .

Note that we plan to release new engine version, 7.0-alpha.2, soon (in a week).

It will be available here (on itch.io) as well as on our webpage https://castle-engine.io/ . For today, if you want to try out the engine, I would recommend checking out our snapshot version, which is the main download on our https://castle-engine.io/ .

Note to whoever reads this: the above comment is outdated. The current engine (from this itch.io page, or from https://castle-engine.io/) features a cool visual editor to design your games visually. See https://castle-engine.io/manual_editor.php .

Note to whoever reads this: the above comment is outdated. The current version on itch.io is "7.0-alpha.1", and it is good :) Still you can always get even more recent ("7.0-alpha-snapshot") version from https://castle-engine.io/.

Yes, donating through https://opencollective.com/castle-engine is welcome. We have a few ways to donate, listed on https://castle-engine.io/donate_other.php .  On the main engine WWW page we focus on https://www.patreon.com/castleengine as this is our preferred method for donation, but all alternative ways listed above are good as well :) Thank you!

Not really. You will need to write some code if you want to do anything beyond a demo. Most of the logic is in the code.

That said, you can start with some example that gives you most of what you  need. For example our "fps_game" example (once you download the engine from https://castle-engine.io/ , it is in "examples/fps_game/" subdirectory) can be extended a lot by just editing the data files. You can add creatures, items by just editing  respective XML files (docs on https://castle-engine.io/creating_data_levels.php , https://castle-engine.io/creating_data_resources.php ).

You could extend fps_game into a full FPS game without much additional code. (But you will still need something, e.g. to show "win" screen, or to code what using new items will do etc.)

Note that the engine version on Itch.io is rather old now (I want to update it once we release engine 7.0). So please download engine from https://castle-engine.io/ now. We've made a lot of new features since 6.4 release ( https://github.com/castle-engine/castle-engine/wiki/New-Features-in-Castle-Game-... ) and  we work on official 7.0 release now.

The next release of this engine is already in-progress, see our news ( https://castle-engine.io/wp/ ) :) You can already try it, using the code from GitHub ( https://github.com/castle-engine/castle-engine/ ).

Instructions how to use the engine are on https://castle-engine.io/ , in particular see the "getting started" page ( https://castle-engine.io/documentation.php ) and the manual ( https://castle-engine.io/manual_intro.php ).

There is no visual application distributed with Castle Game Engine. You usually install Lazarus ( https://www.lazarus-ide.org/ ) to have an environment to edit and compile Castle Game Engine games.

If you expected a visual editor included inside the engine, like Unity3d editor --- I'm sorry, we don't have it yet. But we are working in it, see our plans for 2018 https://castle-engine.io/wp/2017/12/23/plans-6-4-release-asap-visual-editor-soon... :)
