.title Compiling to Assets
|
|
|
|
Compiling project resources into assets is done using the `assetc` command-line tool.
|
|
|
|
Upon invocation, it will scan the input folder and compile all resources in a supported format to the output folder. Files in an unsupported format are copied unmodified to the output folder.
|
|
|
|
*It is very important that you treat the compiled output folder as entirely disposable* and *only ever* perform modifications in the input folder. Output assets will be different for each platform you compile to.
|
|
|
|
Again, *do not ever work in the assets folder*.
|
|
|
|
If you are unclear on the resources/assets distinction see [man.Assets].
|
|
|
|
## Drag & drop
|
|
|
|
The easiest way is to drag and drop the resources folder on the assetc executable:
|
|
|
|
|
|
|
|
## Command-Line
|
|
|
|
If you need more control over the compilation options, the command line gets the following parameters:
|
|
|
|
```
|
|
assetc <input> [output PATH] [-daemon] [-platform PLATFORM] [-api API] [-defines DEFINES] [-job COUNT]
|
|
[-toolchain PATH] [-progress] [-log_to_std_out] [-debug] [-quiet] [-verbose]
|
|
```
|
|
|
|
Option | Shortcut | Description
|
|
-------|----------|------------
|
|
`-input` | | Input project resources folder.
|
|
`-output` | | Output compiled assets folder. If unspecified, the input folder path suffixed with `_compiled` is used.
|
|
`-daemon` | `-d` | Run the compiler in daemon mode. The compiler will constantly monitor the input folder and compile its content as it is modified.
|
|
`-platform` | `-p` | Platform to target.
|
|
`-api` | | Graphics API to target. Some platforms (eg. PC) might support multiple graphics API (DX11, DX12, GL, ...).
|
|
`-defines` | `-D` | Semicolon separated defines to pass to the shader compiler (eg. FLAG;VALUE=2).
|
|
`-job` | `-j` | Maximum number of parallel job (0 - automatic).
|
|
`-toolchain` | `-t` | Path to the toolchain folder.
|
|
`-progress` | | Output progress to the standard output.
|
|
`-log_to_std_out` | `-l` | Log errors to the standard output.
|
|
`-debug` | | Compile in debug mode (eg. output debug informations in shader).
|
|
`-quiet` | `-q` | Disable all build information but errors.
|
|
`-verbose` | `-v` | Output additional information about the compilation process.
|
|
|
|
*Note:* When run in daemon mode `assetc` will not exit after its initial run and will keep watching the input folder. When a resource is modified it will automatically be compiled to the output folder.
