Linking Blender objects to Godot

keltwookie

<h1>Hello all</h1> Really sorry if I'm not into the right area. I searched a bit solutions here before posting but found nothing really appropriate, or I did not well understood. I now try to make it short: Beeing an absolute beginner in Godot and Blender, I started learning both few weeks ago. After having learned that Blender empty objects (harpoints in this case) could be link to a script, I ask if it is possible to use GDScript instead of Python in Blender to link the script to the said object? And if yes how? - Or maybe Python is perfecty compatible with Godot? And in this latest case, how make comunicate a Python script with Godot? Thanks by advance

Either I'm completely not understanding what your asking or you don't quite understand how scripting works. Also, blenders particle hair is not really directly transferable to godot(in theory you could bake them to a mesh and export that, but that's not necessarily the best way to go either).

Sorry, I will try to be more explicite. When I create an object with Blender, I can assign it an "empty object" (I called above "hardpoint"), this empty object could be used to mount Wheels on a vehicle, for example, apllying any action (brake?) commanded by the player. In another case, it could be the place for a weapon or a shield for a RPG/FPS character.. Hope its helps. .

Ah, I haven't looked into it in detail yet, but godot's website offers an alternative collada exporter for blender, that should in theory support exporting a whole scene. I.E. also the empty/null objects.

Yes, I knew for Better Collada (right name?). So GDSript should be able to give particular settings/commands to these Blender objects. Rest to learn how now.. I keep searching :)   Thanks again

the work flow is that you make your 3D objects in blender. and then you export that using Better Collada exporter.  then you import these objects into Godot, and you make all the game logic there. you cannot combine Blenders scripting and logic with Godot.  .b

Yes, that's what I understood, I made tests and the export/import works like a dream. I just now have to deeply dive in GDScript, the most interresting of the whole task in my opinion :D

I'm not an expert, but I think I may be able to provide some level of insight. From what you've shared, it sounds like you are attempting to construct an object hierarchy in Blender, and then import that hierarchy into Godot. While a nice idea, it isn't the workflow that I would recommend. If I were approaching the same problem, I would export the individual 3D models from Blender as separate objects and separate exports. I would then import them into Godot, and construct any needed hierarchy between them within the Godot game engine. Godot has a very clear workflow for instancing and hierarchy. It's one of its stronger aspects. While Blender is also capable of handling complex hierarchies, it is better not to rely on it's structure. I would handle and setup such structures in Godot itself. You can still use Blender to mock-up such structures, no harm in that. Just don't rely on those hierarchies to transfer over when you export. Parenting hierarchies, as well as object-level animations, are better handled within Godot.

Could this be a problem? Of course, I could  export the main shape and the empty object (hardpoint) separately, then copy/duplicate it everywhere I need into Godot. <blockquote class="Quote">Godot has a very clear workflow for instancing and hierarchy.

Anyway, what you wrote is essential and I will try both methods to compare. Thanks for the clues Richard :) <h1> </h1>
