Hi all,
I’m trying to edit the 04_StaticScene example so as to move the mushroom, instead of moving the camera.
I edited the example script as the following.
But when running, it gives errors:
'mushroomNode' is not declared
Illegal operation on 'int'
Failed to compile script module ...
I think replacing cameraNode.translate with mushroomNode.translate should work !!
Why does it give this error!?
This is my edited code:
[code]// Static 3D scene example.

// - Creating a 3D scene with static content
// - Displaying the scene using the Renderer subsystem
// - Handling keyboard and mouse input to move a freelook camera

void Start()
{
// Execute the common startup for samples
SampleStart();
// Create the scene content
CreateScene();
// Create the UI content

// Setup the viewport for displaying the scene

// Set the mouse mode to use in the sample

// Hook up to the frame update events
SubscribeToEvents();
}
void CreateScene()

// is also legal to place objects outside the volume but their visibility can then not be checked in a hierarchically
// optimizing manner
scene_.CreateComponent("Octree");
// Create a child scene node (at world origin) and a StaticModel component into it. Set the StaticModel to show a simple
