Launching Cesium for Unity

Kevin_Ring · December 15, 2022, 1:08am

Any messages in the Output Log? It should be possible to connect to your Android device with the Unity Editor in order to get access to the logs.

Here are log errors I received…

Please check that you’re building for ARM64, not ARMv7. Cesium only supports 64-bit operating systems and processors.

tilt · December 15, 2022, 9:01am

Yes, only Windows (Intel x64), macOS (Intel x64 and Apple Silicon/ARM64), and Android (ARM64) are supported in the current version. It should be possible to build it for Linux on your own system (we have done this in the past), but we don’t currently provide the native code compiled for Linux.

Good to know, we’ll try to build our own. If there are any examples with build options we’d be grateful to be able to look into them, might save us time. Thnks!

Joginder007 · December 15, 2022, 9:19am

When I am doing this… following errors are coming and build is no completing…

Kevin_Ring · December 15, 2022, 10:44am

@Joginder007, I don’t know what to make of those errors. It looks unrelated to Cesium for Unity. Maybe take a look at the full Editor log and see if there are any clues in there. It’s available from the three dots menu in the top right of the console pane.

# Overview

This is a summary of the setup and workflows for developers who want to modify the Cesium for Unity plugin. If you just want to use Cesium for Unity in your own applications, see the main [README](../README.md).

## :computer: Building Cesium for Unity

### Prerequisites

* CMake v3.18 or later (the latest version is recommended)
* [.NET SDK v6.0 or later](https://dotnet.microsoft.com/en-us/download/dotnet/6.0)
* If you're using Visual Studio, you need Visual Studio 2022.
* Unity 2021.3+ (the latest version of the Unity 2021.3 LTS release is recommended)
* On Windows, support for long file paths must be enabled, or you are likely to see build errors. See [Maximum Path Length Limitation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later).
* For best JPEG-decoding performance, you must have [nasm](https://www.nasm.us/) installed so that CMake can find it. Everything will work fine without it, just slower.

The built Cesium for Unity Assembly will run on much older versions of .NET, including the version of Mono included in Unity. However, these very recent versions are required for the C#<->C++ interop code generator (Reinterop).

To make sure things are set up correctly, open a command-prompt (PowerShell is a good choice on Windows) and run:

* `dotnet --version` and verify that it reports 6.0 or later

Any thoughts on this post of mine? In regards to running the maps on Android using downloaded maps from Ion for offline use?

Looking for the same help too …

Dariushuangg · May 21, 2023, 10:52pm

This solved the issue for me. Thanks! For others to reference:
I was trying to run Cesium for Google GeoSpatial 3D tiles on Oculus Quest 2. At first I used Mono as scripting backend, which only supports ARMv7. Everything worked in editor but nothing shows up in my headset. Logcat gives me the error message: “The native implementation is missing so Update cannot be invoked” in Cesium3DTileset-generated.cs script. The solution is to switch to ILCPP scripting backend and choose ARM64 as target architecture.

Hi! I really love cesium for unity but i was just wondering if you could try to provide for building for linux? If you can’t then that’s ok but if you could then thank you :))

Brian_Langevin · March 13, 2024, 5:45pm

We have no immediate plans for official cesium-unity linux support, but feel free to reference related posts on the forum,
