Extension for GDevelop to create simple 3D scenes.
This extension is intended for easy and simple 3D rendering. It does not currently aim for realistic 3D rendering.
📖 How to use
Check out this page.
WithThreeJs Extension for GDevelop
⚠️ Notes on updating from version 1.x.x to version 2.0.0
The "Create 3D Scene", "Load 3D Texture", "Play 3D Sound" and "Create 3D Light" actions have been updated in version 2.0.0.
The previous actions with the same names still work but are deprecated. (Look for the ⚠️ icon in the event.) Please use the new actions with the same names.
🍩 Donation
Currently, I'm doing development in between jobs, but if many people support me, I will be able to devote more time to the development.

🗑️Remove 3D Object
Remove a 3D Object from the 3D Scene.
This action cannot remove 3D Objects created by 3D Projection Behaviors.
This action does not clear the loaded 3D Texture data and the loaded 3D Model data.
They will continue to be accessible by ID.
💥Resolve Bounding Box Collision
Resolve collisions between Bounding Boxes.
It is not necessary to use the "Check Bounding Box Collision" condition beforehand. (It will do almost the same processing)
Note that the 3D Objects are still in contact after resolution. ("Check Bounding Box Collision" condition will not be false.)
3D Object thickness too thin for the amount of movement will not resolve correctly.
This action updates the "Bounding Box Collision Result".
"Bounding Box Collision Result" stores the value when the Target 3D Object is unmoved.
