Using the Tweak Processing Library

Step 4 Tweaks to Tweak

Since Tweak is open source, you can view all of the code and hack it to do whatever you want.

After you've had your fun tweaking, there's a good chance you want to disable the additional window so that it doesn't show up when presenting your sketch.  You may notice that Tweak first checks for "tweak_hasBeenInitialized" before displaying the Tweak Panel.  You can fool tweak into thinking that it has already created the window and keep it from showing up by setting tweak_hasBeenInitialized to true before you instantiate and Tweak type variables.

Here, we modify the example from step 2 to disable the Tweak Panel window.

--------------------------------
TweakInt myNumberR;
TweakInt myNumberG;
TweakInt myNumberB;

void setup(){
   // a hack to hide the Tweak Control Panel:
   // (placed before any variables are constructed).
  tweak_hasBeenInitialized = true;
 
  myNumberR = new TweakInt("Background Red", 100, 1, 0, 255);
  myNumberG = new TweakInt("Background Green", 100, 1, 0, 255);
  myNumberB = new TweakInt("Background Blue", 100, 1, 0, 255);
}

void draw(){
  background(myNumberR.val, myNumberG.val, myNumberB.val);
}
--------------------------------

There's a lot more you can do.  Have fun and let us know what cool stuff you do with it.  Happy Tweaking!
