Result – this is actually game-like!
CatFishTron Creative Pact Day 3
Today’s lesson in that things are always more difficult than they seem. Tried adding a MotionEvent.ACTION_MOVED detector to the onSceneTouchEvent() method of my TouchSprites so they could detect when a finger dragged over them and subsequently would knock them about, but had a bit of trouble. Apparently, as I’ve learned on the excellent AndEngine forum, an object needs to first catch an ACTION_DOWN event before it will start to receive subsequent ACTION_CANCELED or ACTION_MOVED events. This makes sense in hindsight, but it also make things a bit more difficult when you’ve started thinking about it from the other way, as if these events were just globally propagated down the chain of objects that are subscribed to receive them, until one steps up and handles it.
The solution is to create another physics object that’s hidden, and move it about to knock the other objects around when necessary. Also, I had to update it in a different thread, and I still get some crashes occasionally due to memory errors. Need to look at those…
So it looks like “kicking” an object (a cat, in this case) is going to be all I can get done today, because tonight is the opening at The Brick Box in Brixton Market and I’ll be showing Drawn Together there amongst some other visual and artistic goodness.
I did add simple scoring to this version – this should be handled by a GameLogic class, which I’ll work on a bit tomorrow if I get a chance (have some other stuff to do).
Here’s today’s code.
Here’s today’s app. (I overwrote yesterday’s, because, well, it sucked)

Creative Pact Day 2
Today I’m going to create more of a “game,” eventually called CatFishTron. No, really. I’ll be learning how to add sound to a game, a moving background, and maybe, if I have time, add some self-removing sprites (for explosions, etc!)
First task – to make a sprite “blow-up” in AndEngine you use a SequenceModifier and attach it to the Sprite:
this.mBlowupModifier = new SequenceModifier(new ScaleModifier(1.0f, 1.0f, 0.2f));
final IShapeModifierListener listener = new IShapeModifierListener()
{
public void onModifierFinished(IShapeModifier arg0, IShape arg1)
{
// this is a function in my main Activity that removes a sprite entity and physics body in a separate thread
destroySprite(_spriteEvent.mSprite);
}
};
//set a listener to listen for the modification having finished
this.mBlowupModifier.setShapeModifierListener(listener);
// attach it to the sprite entity object
_spriteEvent.mSprite.addShapeModifier(mBlowupModifier.clone());
Here’s today’s code (again, it’s not complete, just building on the previous day, but you might find it interesting…)
Here’s the app itself, you can open the link on your android phone to install it.
It’s a work in progress, remember. It take a bit to make a video game… even a crappy one!
Also, I promise that at the end of this I will write a tutorial.
Now go play MeowTron.

The Cane Toads at Shunt 1 Oct 2009
The Cane Toad Orchestra featuring PixelPusher (or so I like to call it) is playing Shunt next Thursday, Oct 1, 2009, as part of Toplap’s Livecode stage. That’s right, we’ll have no choice but to make some livecoded music and visuals, and that means sonic and visual anarchy of the most chill quality, kind of like a nice late-season muscat dessert wine, full of bite but thick with sweetness like a long summer day. (I think that was a triple-simile, and I might have twisted my ankle landing that one.)
