This leads to code that is easier to understand and runs faster thanks to GDScript's typed instructions. The untyped declaration warning is now enabled on all projects where type hints were added. All projects currently run without any untyped declration warnings. Dodge the Creeps and Squash the Creeps demos intentionally don't use type hints to match the documentation, where type hints haven't been adopted yet (given its beginner focus).
Voxel Game
This demo is a minimal first-person voxel game, inspired by others such as Minecraft.
Language: GDScript
Renderer: GLES 2
Check out this demo on the asset library: https://godotengine.org/asset-library/asset/676
How does it work?
Each chunk is a
StaticBody
with each block having its own
CollisionShape
for collisions. The meshes are created using
SurfaceTool
which allows specifying vertices, triangles, and UV coordinates
for constructing a mesh.
The chunks and chunk data are stored in
Dictionary
objects. New chunks have their meshes drawn in separate
Threads,
but generating the collisions is done in the main thread, since Godot does
not support changing physics objects in a separate thread. There
are two terrain types, random blocks and flat grass. A more
complex terrain generator is out-of-scope for this demo project.
The player can place and break blocks using the
RayCast
node attached to the camera. It uses the collision information to
figure out the block position and change the block data. You can
switch the active block using the brackets or with the middle mouse button.
There is a settings menu for render distance and toggling the fog.
Settings are stored inside of an
AutoLoad singleton
called "Settings". This class will automatically save
settings, and load them when the game opens, by using the
File class.
Sticking to GDScript and the built-in Godot tools, as this demo does, is quite limiting. If you are making your own voxel game, you should probably use Zylann's voxel module instead: https://github.com/Zylann/godot_voxel
