Godot

Exporting

From https://docs.godotengine.org/en/stable/tutorials/rendering/multiple_resolutions.html:

• Use stretch mode = viewport for pixel games

3D

• Get size of a mesh with get_aabb() https://godotengine.org/qa/44825/is-there-a-way-to-get-the-size-of-a-3d-mesh

Connections

Connecting via UI:

Adds the following to the scene file:

+[connection signal="health_changed" from="Characters/Player" to="GUI" method="_on_Player_health_changed"]

Or you can do it programmatically with something like:

# Adds a listener on the mob instance for the event "start_game", hooking into mob._on_start_game
$Hud.connect("start_game", mob, "_on_start_game")

Cameras

Prefer using an interpolated camera. To achieve a spatial offset, create an invisible spatial node and get the camera to follow that instead (https://youtu.be/j2wBsb-W3Ls?t=397). Tweak rotation on camera first, then copy rotation values onto the camera target.

Importing from Blender

• To update .gltf files, untick 'Keep on Reimport' to make sure imports keep updating (https://www.youtube.com/watch?v=grPbk-bfMO4)
• Import 3D Models from Blender into Godot: https://www.youtube.com/watch?v=Q-G8evhxHmc
  • When importing multiple objects in a .blend file, go to Import → Import As → Presets → Import with Separate Objects

Exporting from Blender

Use export as GLTF (more up to date than Collada).

• To apply modifiers, Geometry → Apply Modifiers

Bindings

• <C-b> to build
• In the stage, press <Space> to pan
• F6 to play scene
• F5 to play project
• <S-F1> to look up scripting documentation

Custom

• <C-p> for project settings
