No longer an app store virgin....

Hope ya'll enjoy it... i really enjoyed making it. Cocos2d made it so much easier. Thanks to those that helped me out.

Forgot to put the Japanese link for our couple of Japanese posters...
The title in Japan is KachiKachi Balls... not sure if it is going to connect up in itunes or not...

georgeburns,

It looks pretty cool. Congratulations. However, in the video it seems that the touch response is lacking. In several places it seems like the demonstrator is struggling to grab one or more of the objects. Perhaps that is just due to a poor quality screen protector, but it might be off-putting to potential buyers.

Looks great though. How long did it take? Did you do the artwork yourself?

Best Regards,
Q

Thanks for the constructive feedback. I will replace the video soon...

Probably was focusing too much on centering the device as opposed to where I was putting my fingers. The touch control is actually rock solid.

I used CCTargetedTouchDelegate which is pretty awesome as you don't have to track the touches yourself. I think the other problem is that the touch area of the balls are rather small. I could have expanded the touch area, but then sometimes the users grabbed two balls.

Did the art myself (not sure if that is a good thing or bad thing).

Was working on it since early December off and on. I was completely new to objective c, cocos2d, and anything game/graphics related.

"I think the other problem is that the touch area of the balls are rather small. I could have expanded the touch area, but then sometimes the users grabbed two balls."

what if you just looked at the distance between the touch and all the balls centers - whichever is closest is the one selected (as long as the touch isnt over one of the buttons).

not. It shows up on the web, but it forwards to the US store version.

@Codemattic

Thanks for the suggestion about the nearest ball touch selection... That's a great idea. Wish I had thought of it.

Trying to figure out how to do it right now but a little hung up on how to get the targeted touch delegates to talk to each other. I'm thinking it would have to pass the touch distance to a singleton touch controller logic which would then pass back if it is the closest. Have any thoughts on this?

About the japan app store link... I hat to set up itunes for Japan and the computer language too... then it worked.

Kind of a neat update... Mr. Prebble, the creator of the original Newton's Cradle desk toy endorsed our app. He's a really nice guy.

ok... done with the shameless promotion.

Cocos2d rocks!

I like the concept - it's beautifully executed. I've grabbed PA9RNNK9XMLH and will write a review shortly.

Thats really cool. There is another app like this I downloaded form the appstore. But yours looks soooo much better. Much better physics.

@pfg2009 I appreciate it, hopefully you like it... sort of depressing that a promo code from 6 days ago is still available. lol

@zombie Thanks. Spent a lot of time tweaking it. The main reason I made it was because I didn't think the competition was doing it right.

I really liked it! The sounds and interaction are very realistic and fun to play with. I posted a review.

BTW, have you considered adding more types of balls to play with? Say, marbles, squishy sponges, uneven ice blocks, etc.? Those may be easy to add and expand the playful appeal of the app.

But I agree with zombie; the physics are beautifully done. Good job!

@pfg2009 Thanks for the review. Ya... we are thinking to add marbles next... trying to stick with stuff that is going to be fun to bounce off of each other. Not sure how fun sponges would be ... wouldn't they just stick together? If you have any more good ideas let me know. Thanks again.

georgeburns,

Here's several thoughts for features:

1) Allow balls to be explosive on one side, or allow the balls to be of varying restitution.
2) Not sure if this exists, but a button to (quickly) reset/untangle them would be nice.
3) Allow more than the default # of balls, granted they would need to be smaller or scroll would be needed.
4) Allow people to assign notes to them or allow each successive hit to trigger a note in song (like a nursery rhyme)
5) Personally I would like the basic sounds to be modifyable from a click to other more pleasing metronome sounds.
6) Allow people to set the BPM, this would allow it to be useful as a metronome as well. Granted, you'd have to mess with the physics and gravity, so not sure if you want to go that route.

Anyway, there are all just suggestions, feel free to discard. Nicely done app.

Regards,
Q

questor,

Thanks for the thoughts. I've been experimenting with the explosions actually. And the reset button is in the works. The way I subclassed the ball is making it difficult, but I'm figuring it out.

The balls are adjustable from 1 - 7. Notes would be kind of cool, I'll have to play with that.

We were considering the metronome thing. I think it could be done with the physics... just kill the damping and make the balls perfectly elastic. As long as nothing else happens... should keep a constant beat.

Thanks for all your ideas. We've had several, but knowing what the people want is key.

Just had version 1.1 approved and it's hot on the App Store... hopefully won't get buried under the iPad storm.

Here are some promo codes. If you grab one (and like the app), please review.

See it on iTunes

Here is a video of the new one...

Updated a lot of stuff in this version... added a ball type and worked on some different background skins that move around.

Two of the hardest parts were adding Facebook and Twitter to the mix... complete hair pulling situation but I think it worked out okay.

Please let me know what you think.
