Function physx_sys::PxSceneQuerySystem_prepareSceneQueryBuildStep_mut

pub unsafe extern "C" fn PxSceneQuerySystem_prepareSceneQueryBuildStep_mut(
    self_: *mut PxSceneQuerySystem,
    prunerIndex: u32
) -> *mut c_void

Prepares asynchronous build step.

This is directly called (synchronously) by PxSceneSQSystem::sceneQueriesUpdate(). See the comments there.

This function is called to let the system execute any necessary synchronous operation before the asynchronous sceneQueryBuildStep() function is called.

If there is any work to do for the specific pruner, the function returns a pruner-specific handle that will be passed to the corresponding, asynchronous sceneQueryBuildStep function.

A pruner-specific handle that will be sent to sceneQueryBuildStep if there is any work to do, i.e. to execute the corresponding sceneQueryBuildStep() call.

Null if there is no work to do, otherwise a pruner-specific handle.
