This project has been test-built on Windows using Visual Studio 2019. I'm not sure if they work on other platforms.
- Clone this repository using
git clone --recursiveto get all of the submodules as well. - Create and
cdinto thebuilddirectory at the base of the repository. - Run
cmake .. - Open the VS
RecreatingNoita.slnfile. - Under solution explorer, right click
main> select Properties > ChangeOutput Directoryto thebuild/directory you created in step 2. - Build and run the executable using
RELEASEmode!
- Use the number keys to select a material (the name of the material is outputted into the console).
- Left click to place material, right click to erase material
- Scroll wheel to change the radius of the brush
- Space bar to start/stop the simulation. By default, the simulation starts paused.
- Tab to spawn rigid body bouncy balls (only if
SIMULATE_RIGID_BODIESis set)
Additional configuration is under the USER SETTINGS section of main.cpp.
| Variable | Use | Default |
|---|---|---|
SIMULATE_RIGID_BODIES |
Set this compile flag if you want to simulate rigid bodies. | SET |
SPAWN_BODY |
Set this value to one of NONE, PENDULUM, BOUNCE, or CAR to spawn initial rigid bodies. |
NONE |
DOUGLAS_PEUCKER |
Set this compile flag if you want to approximate particle contours with the Douglas-Peucker algorithm. Greatly increases performance | SET |
DEBUG_DRAW |
Set this compile flag if you want to show calculated contours. | UNSET |
LOAD_FROM_FILE |
Set this compile flag if you want to load a file from disk as initial falling sand state | UNSET |
TEXTURE_FILE |
Set this value to a .b file name under the /assets/ folder. This is the initial state of the falling sand simulation |
|
SIM_WIDTH, SIM_HEIGHT |
The dimensions of the simulation. Lower this if the simulation runs too slow. | 400, 300 |
RENDER_WIDTH, RENDER_HEIGHT |
The dimensions of the render window. Leave this as a whole number multiple of SIM_WIDTH, SIM_HEIGHT |
1200, 900 |
