I never used the 3d commands in AppGameKit before. Can anyone explain why Object2 doesn't move with Object1?

+ Code Snippet

// Includes
#include "template.h"

// Namespace
using namespace AGK;

app App;

int iObject1;
int iObject2;

void app::Begin(void)
{
	agk::SetVirtualResolution (1024, 768);
	agk::SetClearColor( 151,170,204 ); // light blue
	agk::SetSyncRate(60,0);
	agk::SetScissor(0,0,0,0);

	iObject1 = agk::CreateObjectBox(5, 10, 10);
	iObject2 = agk::CreateObjectBox(10, 5, 10);

	// agk::FixObjectToObject(iObject2, iObject1); // This works 
	agk::FixObjectToBone(iObject2, iObject1, 1); // Why doesn't this work?
        agk::SetObjectBonePosition(iObject1, 1, 0, 0, 0);
}

int app::Loop (void)
{
	// Why does Object2 not move with Object1?
	agk::MoveObjectLocalX(iObject1, 0.1f); 

	agk::Print( agk::ScreenFPS() );
	agk::Sync();

	return 0; // return 1 to close app
}


void app::End (void)
{

}

The built in objects in AppGameKit (cube,sphere..etc...) do not have any bones so attempting to fix another object to one with no bones wont work. You can use GetObjectNumBones() to find out if an object has any bones.

Only objects loaded withe LoadObjectWithChildren() have bones so you could use a 3d editor to create a cube with bones if you really wanted to.

As you have already found, using FixObjecToObject() is the right way to do it with bonless objects.

Thanks for the answer. The documentation doesn't mention that requirement.
