Cannot call native C++ method from TypeScript about cocos-engine HOT 3 CLOSED

Update: The exact engine version is 3.8.2. I test the official cocos-example-projects/occlusion-query project with builtin engine (version 3.8.2), build a windows debug application, setOcclusionQueryEnabled() triggers the same error.

In occlusion-query.ts, I add director.root.pipeline.pipelineSceneData.getOctree();, this function is triggered. The modified function onToggle() in occlusion-query.ts is as follows:

    onToggle (toggle: Toggle) {
        if (NATIVE) {
            director.root.pipeline.pipelineSceneData.getOctree();
            director.root.pipeline.setOcclusionQueryEnabled(toggle.isChecked);
        }
        log('Occlusion query enabled: ' + toggle.isChecked);
    }

Why method of PipelineSceneData could be called, while method of RenderPipeline could not? The difference of the two classes I see is PipelineSceneData directly derives from RefCounted, while RenderPipeline does not.

BTW, RenderPipeline::getOcclusionQueryEnabled() seems deleted, so I deleted line 15 of occlusion-query.ts:
this.toggleOcclusionQuery.isChecked = director.root.pipeline.getOcclusionQueryEnabled();

Found the problem. Since v3.6.0, the engine has re-implemented Native render pipeline. When calling director.root.pipeline in TypeScript, Native version will return an instance of RenderPipelineBridge (defined in Root.cpp), which derives from PipelineRuntime cpp class, while TypeScript version will return an instance of RenderPipeline (not a cpp class, defined in render-pipeline.ts).

The official cocos-example-projects are based on engine version 3.4.0, I guess native version of director.root.pipeline returns an instance of RenderPipeline (cpp class, defined in RenderPipeline.h)

Sorry for the inconvenience.

To support custom render pipeline in 3.6.0, we have refactored the native engine.
The custom pipeline and legacy pipeline share the common PipelineRuntime interface.

Native RenderPipeline cannot be access from typescript anymore, as we are moving forward to the custom pipeline.

Currently, occlusion query is not well supported in custom pipeline. The reason is that we have not yet worked out a cross-platform solution.

We might support occlusion query in the future release, and are also considering other methods such as PVS (potential visible set).
