Texturing/Coloring wherever you go

Questions & Answers

I am working on a 3D Platform-ish game… Its basic scheme is Black and White-ish what i want is that where ever the player object goes from that area (not that specific place but the whole area ) should get colored/textured a little help will be appreciated. Thank You!

Hi! I’m not sure I understand your definition of place/area. Assuming you have 4 rooms on screen, each room an “area”, you could do the following:

1-add the following script to every object you want to be affected

var basicTexture : Texture;
var colouredTexture : Texture;
function Start()
{
      renderer.material.mainTexture = basicTexture;
}
function SwapTexture()
{
      if(renderer.material.mainTexture == basicTexture)
      {
            renderer.material.mainTexture = colouredTexture;
      }
      else
      {
             renderer.material.mainTexture = basicTexture;
      }
}

2-make all objects of a room(“area”) children of a trigger (invisible flat cube, isTrigger enabled)
-Add the following script to your triggers

function OnTriggerEnter(coll: Collider)
{
   if(coll.tag == "player")  // tag or name or transform whatever works for you
   {
        BroadCastMessage("SwapTexture");
   }
}

function OnTriggerExit(coll:Collider)
{
   if(coll.tag == "player")  // tag or name or transform whatever works for you
   {
        BroadCastMessage("SwapTexture");
   }
}

It’s rough, but should work. You could refine it by having one or two intermediate textures to smooth it out.

P.S.: I’m new to Unity, but this question seemed like one I could answer quite safely. @More experience coders : if my reply is inadequate please enlighten me, as I’m sure there are more elegant ways of doing this…
