Scene3D - make 3D games with Defold
Scene3D is a collection of assets to help you developing 3D games with the Defold game engine. Use included prefabs to quickly prototype structures, levels, and to test game mechanics. Try out ideas quickly!
The built-in example scene is available ✨to play online✨. Controls:
WASD
to run or drive,SPACE
to jump. Mouse to look.4
to switch between character/car.- Special keys:
5
to reload current scene,6
to load next scene,0
to toggle photo mode (move the mouse to look,WASD
to fly,SPACE
to go up,C
to go down,M
to copy camera settings). - In the debug build:
1
to toggle physics debug,2
to toggle profiler.
Follow further developments:
Key features
- Car physics.
- Character controller.
- Controls: keyboard, mouse look with a pointer lock.
- Frustum culling (only for 3D meshes).
Included Assets (i.e. Prefabs)
- Camera. Options: clear color, FOV, near clip, far clip.
- First-person mouse-look with a pointer lock support.
- Orbit camera script to follow an object in a third-person view.
- Directional Light. Options: ambient color, intensity, light direction, fog color, fog range.
- Chunked Floor. Spawns objects from a factory to make an "infinite" world around an object.
- Late Update. It calls your scripts after all
update
functions have been called and physics objects have been moved. - Request more or contribute.
Debugging
- Photo mode: press
0
to capture controls and observe the scene. The mode controls: move the mouse to look,WASD
to fly,SPACE
to go up,C
to go down,M
to copy camera settings,Enter
to take a screenshot.
Buildings
- Floor: 1x1, 2x2, 5x5, 10x10.
- Walls: 0.1x1x3, 0.1x5x3, 0.1x10x3.
- Blocks: 1x1x1, 3x3x3, 5x5x5.
- Walls with door frames.
- Walls with window frames.
- Stairs 1x1.
- Ramps 1x1, 3x3, 1x2, 3x6.
Environment
- Sky: texture mapped on sphere.
Icons
- Arrow (right), cog, flag, flash, heart, home, key, location, lock closed/open, music, puzzle, spanner, star, tick, video.
- Letters A-Z, numbers 0-9.
Primitives
- Cone.
- Cube.
- Cylinder.
- Pyramid.
- Sphere.
- Tube.
Props
- Road cone.
- Soccerball.
Materials
-
basic_color.material
- colors your model + the simplest shading. The mesh should have the "color" stream. -
basic_grid_*.material
- it puts a texture on your objects without having to make UV’s. -
basic_unlit.material
- the simplest possible textured material.sky.material
is the same but with a different tag. -
primitive_*.material
- no textures, only applies tint on your model.
Some materials have a tint from the palette: Nickel, Timberwolf, Pacific Blue, Verdigris, Middle Blue Green, Medium Champagne, Maximum Yellow Red, Atomic Tangerine, Salmon, Candy Pink.
Included shaders don't apply gamma correction.
Current Status
- ✔️ It's suitable for production, but be aware that API, scripts, project structure aren't in a finished state and may be changed.
- ✔️ If you are making the game with Scene3D, follow the optimization section below before releasing your game.
How To Use
Before You Start
Scene3D uses the metric system, i.e. metres as its default unit for measuring distance/length, i.e. 1 unit is 1 meter.
- Coordinate system: OpenGL, i.e. a right-handed system - the positive x-axis is to your right, the positive y-axis is up and the positive z-axis is backwards. The forward direction is
vmath.vector3(0, 0, -1)
.
Installation
Use it in your own project by adding this project as a Defold library dependency. Open your game.project
file and in the dependencies field under project add the link to the ZIP file of a specific release.
Required Dependencies
- Pointer Lock (only if a project uses
mouse_look.script
or thedebug_camera
prefab).
Optional Dependencies
Scene3D can use the following dependencies if you include them in your project:
Included Scenes
-
playground
: a playable level with a first-person character controller and a car. Loaded first. -
basic_3d
: use it as a template to start developing a new 3D project/scene.
game.project
Settings
The At this moment, Defold supports only Bilinear (Linear Mipmap Nearest) or Trilinear (Linear Mipmap Linear) filtering to apply to textures. Scene3D can enable anisotropic filtering for all textures in the builds for the HTML5 platform:
[scene3d]
anisotropic_filtering = 8
Known Issues
- Frustum culling uses camera matrices from the previous frame.
Optimization
TODO
... Add information about the over-use of scripts and how to optimize them. ... Add info about shaders optimization, downsizing meshes buffers.
Vote For The Issues
The following issues are critical for the further development of Scene3D. Please put 👍 on them!
- Control sort order of rendered primitives + Allow sorting front-to-back.
- Material option to enable anisotropic texture filtering.
- Optimize file size of Buffer.
- More matrix types as shader constants.
- Custom vertex format.
- IDE: Copied collision 3d box doesn't show properly in the editor.
Contributing to Scene3D
👍🎉 First off, thanks for taking the time to contribute! 🎉👍
Scene3D tries to follow the principles:
- Developer-friendly: it should be user-friendly and have a comfortable learning curve to make it a good choice for developers of any experience.
- Mobile-friendly: it should be able to run on mobile and web platforms.
- Ready-to-use: the included components should be ready for production.
When creating a bug report, please include as many details as possible. If you find a Closed issue that seems like it is the same thing that you're experiencing, open a new issue and include a link to the original issue in the body of your new one.
Please, follow code formatting style of the project:
- The default indentation is 4 spaces for the all code, i.e. Lua, C++, HTML/CSS/JS, GLSL. Who prefer to use tabs to indent code, configure git to automatically switch between spaces and tabs.
- Use
snake_case
when naming files, Lua variables, objects, functions, and instances. - This Lua Style Guide mostly suits the project well.
