How to handle world center like Sphero RollingDead

February 2, 2016 - 7:35am #1
Hi all,
 
I wanna make a game like Sphero RollingDead,but now i found the world center is a big problem.
 
 
 
There are 3 world center mode in ARCamera,and none of these mode can work like Sphero RollingDead.
 
1.Specfic Target
The Tatget would be the player,if i choose this mode. When i move the Sphero, the zombie set in the world would move the same displacement at the same time.
 
2.Firsr Target
The same with Specfic Target.
 
3.Camera
If i move the Camera, the zombie would move with Camera, it keep its position on screen, can't change .
 
 
So i don't know how to handle this. I thought the World Center should be made with "third target"(not the Sphero nor the Camera). Maybe I can choose one real third target(it shouldn't move in the whole game) into world center, but it got more steps then Sphero RolingDead.
 
 
Does anyone know how to make this world center.

Hi,

 

I am trying to do something like you and I decided that I will use another marker to build the scene (a marker on the floor for example). So the wolrd center will be this marker.

 

Anyway, I wonder how did you tracked the Sphero? Did you used Object Tracker from Vuforia?

 

Thanks
