This avoids confusion with the old `bits=64` option and building for 64-bit CPUs in general.

# How to build and run
|
|
|
|
1. Build Godot with the module enabled: `module_mono_enabled=yes`.
|
|
2. After building Godot, use it to generate the C# glue code:
|
|
```sh
|
|
<godot_binary> --generate-mono-glue ./modules/mono/glue
|
|
```
|
|
3. Build the C# solutions:
|
|
```sh
|
|
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin
|
|
```
|
|
|
|
The paths specified in these examples assume the command is being run from
|
|
the Godot source root.

# How to deal with NuGet packages
|
|
|
|
We distribute the API assemblies, our source generators, and our custom
|
|
MSBuild project SDK as NuGet packages. This is all transparent to the user,
|
|
but it can make things complicated during development.
|
|
|
|
In order to use Godot with a development of those packages, we must create
|
|
a local NuGet source where MSBuild can find them. This can be done with
|
|
the .NET CLI:
|
|
|
|
```sh
|
|
dotnet nuget add source ~/MyLocalNugetSource --name MyLocalNugetSource
|
|
```
|
|
|
|
The Godot NuGet packages must be added to that local source. Additionally,
|
|
we must make sure there are no other versions of the package in the NuGet
|
|
cache, as MSBuild may pick one of those instead.
|
|
|
|
In order to simplify this process, the `build_assemblies.py` script provides
|
|
the following `--push-nupkgs-local` option:
|
|
|
|
```sh
|
|
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
|
|
--push-nupkgs-local ~/MyLocalNugetSource
|
|
```
|
|
|
|
This option ensures the packages will be added to the specified local NuGet
|
|
source and that conflicting versions of the package are removed from the
|
|
NuGet cache. It's recommended to always use this option when building the
|
|
C# solutions during development to avoid mistakes.
|
|
|
|
# Double Precision Support (REAL_T_IS_DOUBLE)
|
|
|
|
Follow the above instructions but build Godot with the precision=double argument to scons
|
|
|
|
When building the NuGet packages, specify `--precision=double` - for example:
|
|
```sh
|
|
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
|
|
--push-nupkgs-local ~/MyLocalNugetSource --precision=double
|
|
```
