So you’re on 10.6, you want to be able to open a folder in Finder with TextMate, you could write a quicksilver trigger for it ( that doesn’t work for me ) you could write a SIMBL plugin ( too much work, could be unstable ) or you could find a third party app to do it ( more resources used )

Nope, we use the new Automator’s services, so load up Automator, and choose Service.

The global input needs changing to files or folders, I then set the application to Finder only as it’s less likely to have key-binding conflicts.

Add a Run Shell Script action, and put in this command ’ cat | xargs mate ’ this will send TextMate the files. Only one more step, and that’s to assign a key binding! This is done in the Keyboard Preference Pane, just double click in the gap where a key command should be to assign your own. I like to keep it consistent with Cyberduck ( beware that this conflicts with an existing Finder command )

So its one of those ironies, everyone is one, but no-one wants their stuff pirated.

I’ve wrote a more or less drag and drop in game for people using cracked IPA’s that’ll show if the game detects its cracked, no real effort, but for now its not finished, so I’ll repost the code I found here at How to thwart IPA Hackers


- (void) applicationDidFinishLaunching:(UIApplication*)application
{
[[Director sharedDirector] setAnimationInterval:1.0/60];
[[Director sharedDirector] setMultipleTouchEnabled:YES];
Scene *scene = [Scene node];
// [scene add: [OptionsLayer node] z:0];
//[scene add: [MenuLayer node] z:0];
// [scene add: [GameLayer node] z:0];
[scene add: [IntroLayer node]];
//anti piracy
NSBundle *bundle = [NSBundle mainBundle];
NSDictionary *info = [bundle infoDictionary];
if ([info objectForKey: @"SignedIdentity"] != nil){
[scene removeAll];
[scene add:[PirateGame node]];
}
[[Director sharedDirector] runScene: scene];
}


I like keeping around ways of directly accessing scenes at the begining for debug, totally useful.

Chipmunk and Cocos2d

In Short: With the right methods set up anytime you add a sprite to the data part of a cpShape than it will draw the sprite and set its rotation on every frame.

In long: Lets say your starting from a new cocos2d project that compiles. First you’re going to want to set up the chipmunk engine, I have a nice little helper method for this, that’s well commented.


- (void) initChipmunk{
// start chipumnk
// create the space for the bodies
// and set the hash to a rough estimate of how many shapes there could be
// set gravity, make the physics run loop
// make a bounding box the size of the screen
cpInitChipmunk();
space = cpSpaceNew();
cpSpaceResizeStaticHash(space, 4, 20);
cpSpaceResizeActiveHash(space, 50.0, 500);
space->gravity = cpv(0, -200);
staticBody = cpBodyNew(INFINITY, INFINITY);
[self schedule: @selector(step:)];
// Game specific logic here.
}


Next I would write the code for the physics run loop, luckily Riq has made this for me, and the less code I’ve wrote the better


-(void) step: (ccTime) delta {
int steps = 2;
cpFloat dt = delta/(cpFloat)steps;
for(int i=0; iactiveShapes, &eachShape, nil);
cpSpaceHashEach(space->staticShapes, &eachShape, nil);

}


This will keep the chipmunk engine working in realtime (because if frames get skipped than the dt will go up) we then give cpSpaceHashEach a method pointer (in the case &eachShape) to have this method called on every static/active object in the space. This has to be a C method, so lets look at that


static void eachShape(void *ptr, void* unused){
cpShape *shape = (cpShape*) ptr;
Sprite *sprite = shape->data;
if( sprite ) {
cpBody *body = shape->body;
[sprite setPosition: cpv( body->p.x, body->p.y)];
[sprite setRotation: RADIANS_TO_DEGREES( -body->a )];
}
}


This is a great piece of code in my opinion, again, Riqs work. we make a shape from the void pointer then check if it has a sprite in its data, if so, set the position and rotation in accordance to the chupmunk body. Perfect.
That’s the longer explaination of how Chipmunk connects to Cocos2d.

I really advise checking out both thrown and grabbed as they have some useful helper methods for making shapes quickly and throwing them into your scene that I was tempted to add to this post.
