Question by OneOnePuty · Sep 17, 2017 at 08:07 PM · movementcontrollerzoomrotatearoundtouches

[Android/ iOS] - 3D - touch move, zoom, rotate such as GPS navigation

Hi, I working with 3D game, perspective camera and i need create Touch Input manager. I could'n find solution to my issue about camera move, zoom and rotate around game plane. I try to build Input manager to my game,and i need to:

  • if (Input.touchCount == 1) { } // i want to camera movement

  • if (Input.touchCount == 2) { } // i want to camera zoom

  • if (Input.touchCount == 2) { } // i want to camera rotate around game plane

If is only one touch detected, camera will be movement, If is two touch detected - like as zooming - two fingers move closer or further - Camera will be zooming If is two touch detected - like as rotating - two fingers are rotate around display - Camera will be rotate around game plane, not around its own axis.

I try to manipulate about camera like as in GPS navigation, such as Google Maps. I try a lot of tuturials but no one works. Please can anybody to help me?

Thanks a lot.
