Low FPS during Build

[Baal]

Hi. I want make game with terraforming, building roads etc. Using 2d Toolkit. I writen this code:

Code: [Select]

   Plane p = new Plane(Tmap.transform.forward, Tmap.transform.position);
      Ray ray = Camera.ScreenCamera.ScreenPointToRay (Input.mousePosition);
      //RaycastHit rayhit;

      float hitD = 0;
      if (p.Raycast(ray, out hitD))
      {
         float fx, fy;
         if (Tmap.GetTileFracAtPosition(ray.GetPoint(hitD), out fx, out fy))
         {
            xxx = (int)(fx);
            yyy = (int)(fy);
            // you know what tile you're hitting now
               Debug.Log("x: "+xxx+" y:"+yyy);
         }
      }
      if (Input.GetMouseButtonDown (0)) {
         Tmap.SetTile(xxx,yyy,1,5);
         Tmap.Build();
      }To change Tile in TileMaps (change Tiles to Road Tiles) But every time when i click my FPS was falling from 70+ to 30 and my character ignore collision (jump over river) so i can't use this solution in game There is any other way to smooth tile changing?

Build WILL be expensive if you have colliders. As the docs say: "Avoid building tilemaps every frame if you use Unity colliders as it will likely be too slow for runtime use.". If you need to build stuff at runtime, disable colliders and manage it yourself, eg. building a "skin" of box colliders pulled out of a cache is one way of doing this efficiently.
