Build Error using Cesium sourcecode

seongholee · November 8, 2024, 7:55am

Hi. I have some build error.
I move the “CesiumforUnreal” folder in marketplace to “Plugins” Folder in MyProject.
and I built it. That is ok.
After That,
In My Actor cpp, I used component in cesium source code(ex- “CesiumGlobeAnchorComponent”) and build.
It results in crash.
and Unreal displayed "Unhandled Exception:EXCEPTION_ACCESS_VIOLATION"error in Crash reporter.

How to solve?

Current My Project:
CesiumforUnreal version: 2.9.0. and It downloaded in marketplace.
“Plugins” Folder - “CesiumForUnreal”
“MyProject.Build.cs”, I add “cesiumEditor” and “CesiumRuntime” to PublicDependecyMouleNames.

Hi @seongholee,

I’m not aware of any reason that CesiumGlobeAnchor would specifically fail when the plugin is embedded in a project. So my first guess is that your code that is attempting to use CesiumGlobeAnchor in a way that is somehow incorrect, and that is causing the crash? In order to help us diagnose, we probably need to see the code. It would also be a big help to see the full call stack of the access violation.

Hi @Kevin_Ring ,
MyActor.h

class UCesiumGlobeAnchorComponent* GAC;

MyActor.cpp

AMyActor::AMyActor()
{
GAC = CreateDefaultSubObject(“GAC”);
}

and build
=> crash

Below is crash reporter. I’m sorry too long.

@seongholee that doesn’t look like valid code. CreateDefaultSubObject needs a template parameter, doesn’t it?

In any case, I can’t really tell what’s going on here. Your call stack isn’t very helpful because you don’t seem to have Unreal Engine symbols installed. But I think it’s notable that it doesn’t have AMyActor or anything Cesium related in it. Which makes me wonder if the crash has some cause that is unrelated to this code?

We use CreateDefaultSubObject with a CesiumGlobeAnchor in our own CesiumSunSky.cpp, so I believe that should be working fine:

github.com

CesiumGS/cesium-unreal/blob/v2.10.0/Source/CesiumRuntime/Private/CesiumSunSky.cpp#L107


      
            // The Sky Atmosphere should be positioned relative to the
            // Scene/RootComponent, which is kept at the center of the Earth by the
            // GlobeAnchorComponent.
            SkyAtmosphere =
                CreateDefaultSubobject<USkyAtmosphereComponent>(TEXT("SkyAtmosphere"));
            SkyAtmosphere->SetupAttachment(Scene);
            SkyAtmosphere->TransformMode =
                ESkyAtmosphereTransformMode::PlanetCenterAtComponentTransform;
            SkyAtmosphere->TransmittanceMinLightElevationAngle = 90.0f;
          
            this->GlobeAnchor =
                CreateDefaultSubobject<UCesiumGlobeAnchorComponent>(TEXT("GlobeAnchor"));
            this->GlobeAnchor->SetAdjustOrientationForGlobeWhenMoving(false);
          }
          
          void ACesiumSunSky::_handleTransformUpdated(
              USceneComponent* InRootComponent,
              EUpdateTransformFlags UpdateTransformFlags,
              ETeleportType Teleport) {
            // This Actor generally shouldn't move with respect to the globe, but this
            // method will be called on georeference change. We need to update the sun
