Code

The readme.txt file in the download ZIP (linked to at the left) provides full instructions on installing and using the code.  Example document classes are provided.  Below is the operative code from the samples so that you get the idea.

Assuming that you import the dodo package as detailed in the ZIP file.

private var myCamera:DodoCamera;
private var myBlobs:DodoBlobs;
private var myConfig:DodoConfig;

public function Blobs() {          

 // make a DodoCamera object            
 myCamera = new DodoCamera();    
 addChild(myCamera);            

 // make a DodoBlobs object
 myBlobs = new DodoBlobs(myCamera);
 addChild(myBlobs); 

 // config lets you set sensitivity via a slider
 // pressing SHIFT D for Dodo will toggle the visibility
 myConfig = new DodoConfig(myBlobs);
 addChild(myConfig);

}
