2½D Game’s Touch Camera Controls
Hi,
I am developing a Tower Defense Themed Game and everything is working perfect except camera. I need help for Fixing Bugs.
Btw My Camera Must Moving X and Z coordinates not X and Y so i try to screen x,y to world x,z too.

public static class Extension

public static Bounds OrthographicBounds(this Camera camera)
{
var t = camera.transform;
var x = t.position.x;
var z = t.position.z;
var size = camera.orthographicSize * 2;
var width = size * (float)Screen.width / (float)Screen.height;
var height = size;
return new Bounds(new Vector3(x, 20, z), new Vector3(width, 20, height));
}
}
When I try pinch to zoom out for orthographicSize's bug and orthographicSize even going crazy to Negative Numbers and decreasing till -1000000
