This tool visualizes the assembly compilation process in Unity3D. It hooks into the Editor-provided events and nicely draws them on a timeline. That's especially helpful when trying to optimize compile times and dependencies between assemblies.
Besides showing a graphical view of compilation, selecting an assembly shows both dependencies and dependents of that assembly.
The screenshots show full compilations; but the timeline works as well for partial compilations (e.g. you changed a single script and Unity only recompiles the relevant parts of the dependency chain).
Compilation Visualizer is available on OpenUPM: https://openupm.com/packages/com.needle.compilation-visualizer/
If you're on Unity 2019.4+:
Edit/Project Settings/Package Manager
Name: OpenUPM
URL: https://package.openupm.com/
Scope(s): com.needle.compilation-visualizer
com.needle.compilation-visualizer
You can open the Compilation Visualizer by selecting Window > Analysis > Compilation Timeline
. It will automatically update whenever something is compiled.
If you want to trigger a recompile, you can either use the Recompile button, or Right Click > Reimport
a script or folder with scripts to cause that to be recompiled.
You can also compile player scripts only, by clicking Compile Player Scripts. Use the dropdown button to switch to another platform.
On 2021.2+, Unity changed how compilation results are cached. The Recompile and Compile Player Scripts will clear those caches to allow measuring a full compilation run.
Left Click to select a specific assembly. This will show dependencies and dependants. Hover over an assembly to get additional details. Alt + Scroll Wheel to zoom in/out. Alt + Right Click to reset zoom.
Compact will toggle between a waterfall view of all assemblies, and a compact collapsed view that tries to save space. Logging turns on a lot of extra logs that will be put into the Console when clicking on an assembly. Show Reloads adds an extra section in the timeline to see how much time went into compilation and how much into the following Domain Reload.
Compilation Visualizer can run edit mode tests to ensure your project compiles on all platforms, catching common mistakes with ifdefs and API compatibility. To use these tests, simply add it to the "testables" section in your project manifest.json:
"testables": [
"com.needle.compilation-visualizer"
],
Then, when you open Window > General > Test Runner
you can click Run All or double-click CompilePlayerScripts
.
While most functionality works great those versions, some minor things are different:
PackageInfo.FindForAsset
doesn't exist.On 2021.2, sometimes UnityEditor.UI.dll
and UnityEditor.TestRunner.dll
are included in Player Builds for reasons.
