Help with Component Definition


#1

I create a component definition:

        SUComponentDefinitionRef comp_def = SU_INVALID;
	SUComponentDefinitionCreate(&comp_def);
	
	SUComponentBehavior behavior;
	behavior.component_always_face_camera = true;

	SUComponentDefinitionSetBehavior(comp_def, &behavior);

	SUModelAddComponentDefinitions(model, 1, &comp_def);

I am creating my model with SUGeometryInputRef, so I can use SUGeometryInputFaceSetFrontMaterial since I am mapping my texture. I then use SUEnititesFill. I am filling the enitites from SUModelGetEntities. How can I add my component behavior to this model?

I used the following code to create an instance. But it does not do what I want. It pauses before it opens my model and waits for me to click then it places it at the origin. It also does not always face the camera.

                SUComponentDefinitionRef comp_def = SU_INVALID;
		SUComponentDefinitionCreate(&comp_def);
	
		SUComponentBehavior behavior;
		behavior.component_always_face_camera = true;
		

		SUComponentDefinitionSetBehavior(comp_def, &behavior);

		SUModelAddComponentDefinitions(model, 1, &comp_def);

		SUComponentInstanceRef instance = SU_INVALID;

		SUComponentDefinitionCreateInstance(comp_def, &instance);

		//SUStringRef name = SU_INVALID;
		//SUStringCreateFromUTF8(&name, "always face camera");
		
		SUEntitiesAddInstance(entities, instance, NULL);
