Initializing Camera on child node problem

Hi all,

I’m running in to an issue when I try to create a camera component on a child node (in C++). Here’s code that works:

[code] // Create the camera
cameraNode_ = scene_->CreateChild(“OrbitCamera”);
orbit_cam_ = cameraNode_->CreateComponent();
child_node = scene_->CreateChild(“CamNode”);

Camera* camera_ = cameraNode_->CreateComponent<Camera>(); //NOTE: creating a camera on this node works fine

[/code]

However, when I change the code so that I create the camera on a child node of ‘cameraNode’, I get a black screen:

[code] // Create the camera
cameraNode_ = scene_->CreateChild(“OrbitCamera”);
orbit_cam_ = cameraNode_->CreateComponent();
child_node = scene_->CreateChild(“CamNode”);

Camera* camera_ = child_node ->CreateComponent<Camera>(); //NOTE: creating a camera now gives me a black screen

[/code]

Can’t figure it out. Btw, having a camera on a child object is very useful for 3d Camera rigs (i.e. the parent node is the Pivot point), I would like to get this working. Also, this code is just running in the standard CreateScene method, taken almost verbatim out of the samples.

What’s the code look like that creates the Viewport? I have a feeling that the Camera object you’re passing to it is now a nullptr.

Here’s the viewport code:

[code]Renderer* renderer = GetSubsystem();
// Set up a viewport to the Renderer subsystem so that the 3D scene can be seen
IntRect* rect = new IntRect(0,0,1024, 680);
SharedPtr viewport(new Viewport(context_, scene_, cameraNode_->GetComponent()));

renderer->SetViewport(0, viewport);
renderer->SetShadowMapSize(2048);
renderer->SetShadowQuality(2);

ResourceCache* cache = GetSubsystem<ResourceCache>();
RenderPath* render_path = new RenderPath();
render_path->Load(cache->GetResource<XMLFile>("RenderPaths/ForwardDepth.xml"));
viewport->SetRenderPath(render_path);[/code]

Hmmmmmmmmmm................

Hmmmmmmmmmm…

That’ll do it :slight_smile: Thanks for your help.
