[Note][Unity3D] Dynamically modify Canvas renderMode, sortingLayerName, sortingLayerId properties

Set sortingLayerName and sortingLayerId properties in renderMode renderMode. ScreenSpaceOverlay situation will not take effect, Leave sortingLayerName=Default and sortingLayerId=0. When the renderMode property is read, the following judgments are performed:

RenderMode {get {...if(m_renderMode == RenderMode.ScreenSpaceCamera && m_camera == null)
        {
            returnRenderMode.ScreenSpaceOverlay } ... }}Copy the code

Therefore, to change sortingLayerName and sortingLayerId, you must set the Camera first
