iPhone App Build Size

2011-06-28T05:50:00.000-07:00

Build Size After Apple Approve.

Why People interested in–” less than 20 MB for Build size” ?…

Its a Limit of data download via GPRS. By “Apple” and Service Providers. Previously the limit was 10MB and anything additional needed to be downloaded via Wi-Fi.

“This limit now appears to have been increased to 20MB in both the App Store and iTunes Store on the device, allowing users to download larger applications and video content.”

link: http://blog.jcmultimedia.com.au/2010/02/apple-doubles-maximum-app-size-download-over-3g-or-edge-to-20mb.html

The reason why might be timed to get users used to downloading bigger apps before before the iPad arrives, or it could be a quiet response to an increasing demand for apps on the run over 10MB.

So its affects on sales of the application, user must have computer/itunes to download and then sync with Device.

What Apple adds with the Build ?…

To calculate the build size on the appstore for the application,we first must find what apple adds in to it.
1. iTunes Artwork (70 Kb)
2. iTunes Metadata.plist (2 Kb)
3. Files in the SC_folder (12 Kb)
4. Code Resource files (9k)
– Total 100 KB.

Some people still complain about increasing the size in Mega Bytes ?

The answer is simple, and surprising.
1. Apple is encrypting the executable file.
2. By doing so its size doesn’t change much but its contents do which usually can no longer be compressed as much as before

Then What’s Happening actually,…?

By putting all this together i came up with a way to calculate the maximum size of your App in the App Store (it will most likely be less than this):
1. open the .app bundle via right-click -> Show Package Contents (on Mac)
2. locate the executable file and remember its (uncompressed) size (Size “A”)
3. delete the executable from the bundle
4. zip the bundle and remember the bundle’s compressed size (Size “B”)
Size “C” are the 100 KB from the additional files added to the bundle by Apple. The final calculation for the maximum size of your App is as follows:
A + B + C = maximum size of your App after approval
The calculation put in words:
(uncompressed executable size) + (app bundle compressed but without executable) + 0,1 MB = maximum size of your App after approval
but remember: we calculated the maximum size the App might have.
Depends on Framework ? COCOS2d or UIKIT or UNITY3d ?
YES, Depending on your code and more likely the engine you use (i use cocos2d exclusively till now) the amount of compression lost by Apple’s encryption varies greatly.

Especially if assets (images, sound, music) are embedded in the executable (so don’t do that!). I hear that Unity iPhone applications can suffer a great deal more, however i don’t know if there was anything particular about the App nor which version of Unity iPhone was used, so take it with a grain of salt.

Why Apple Encrypts ?….

d encryption is for DRM purposes — to protect your apps from you (a.k.a. the bad guy, a.k.a. Mallory in cryptographic scenarios). The usual compress-then-encrypt steps would require a decrypt-then-expand step later, and that’s a no-no in DRM land. Instead, they probably decompress the package when installing it on the device (mostly as a convenient transport format rather than to save bandwidth), then leave it in the encrypted state in flash memory. It’s likely decrypted on the fly — at late as possible — to execute the code, but the OS doesn’t ever lay the whole image out there in plaintext where you might be able to have a look at it.

Chess Game Algo With 20 lines....

This is the algo that I had developed when I started my game development. This code contains all kind of rules that belongs to the standard Chess, I made it as small as I can..

#define F(I,S,N)
for(I=S; I < N; I++)
#define W(A) while(A)

int V=112,M=136,I=8e3,C=799,X,Y,Q,N,
d[]={-16,-15,-17,0,1,16,0,1,16,15,17,0,14,18,31,33,0,

b[128]={6,3,5,7,4,5,3,6};

char n[]=".?+pkltd?*?PKLTD";

if(y+r+1&128){b[y]|=7;v+=C;}
}
v=-D(24-k,-l,-m,z=-e-v,y,h);
v-=v>I/3;
if(x==9){if(v+I&&i==X&y==Y){Q=z;return l;}v=m;}
b[i]=u;b[y]=t;

if(v>m){m=v;if(x&8){X=i;Y=y;}}
}

}W(!t);
}
}
}W(i=i+9&~M);
return m+I?m:-D(24-k,-I,I,0,x,1)/2;
}

main()
{
int k=8,*p,c[9],d;

F(X,0,8)
{b[X+V]=(b[X]+=16)-8;b[X+16]=18;b[X+96]=9;
F(Y,0,8)b[16*Y+X+8]=(X-4)*(X-4)+(Y-3.5)*(Y-3.5);
}

W(1)
{F(N,0,121)printf(" %c",N&8&&(N+=7)?10:n[b[N]&15]);
p=c;W((*p++=getchar())>10);
if(*c-10){X=*c-16*c[1]+C;Y=c[2]-16*c[3]+C;}else
{d=6;N=0;W(N<1e6)D(k,-I,I,Q,8,d++);}
if(D(k,-I,I,Q,9,2)==I)k^=24;

}

Its really works...

10 steps to be a Game Developer

2009-11-25T03:44:00.001-08:00

Gaming is something which makes you different , Makes you enjoy the moment like you were doing it for real.Sometimes we feel making designs.May be not everybody but who are good at designs and logic can make an awesome game to remember.
So what you do before you start making a game.!!!! Read about it not games but how to make game design and everything.Here are some if we can follow those points….you have a kick start.

1.The Kiss Factor:

KISS stands fro Keep it simple Stupid.When you design a game, the most important factor is whom are targeting.The message should be passed in such a way that even a simple person can understand.The goal of game should be simple and must be expressed in few words, like”Save the princess”,”You need more money”.Avoid essays.

2.Communication Statements:

How you communicate to the users trough the game is what matters.You should have statements which are simple and explainative but not very long.They should be able to tell the user what he or she is intended to do.Gamers might not be very sophisticated computers user, so your game should be able to guide them through out.

3.Puzzle has to be structured properly

Every game weather its action or arcade has certain degree of puzzle involved in it.Don’t make gamers aimlessly wander for the puzzle.Plus don’t have just one puzzle that can solve that stage.Have a couple of puzzle intermingled with the stage which change with every stage, giving the user a new thrill at every stage.Don’t keep it too simple neither the same every time.More variations will make your game look very new every time the player plays.

4.Balance the difficulty of puzzles.

This is one of the major factor as per my gaming experince says(well not designing but playing).As per the 3rd point you need puzzles but how you throw it to user it depends.Every game has puzzles which has a certain level of difficulty.Increase your difficult level as the stages increase.Rewards them some points and give another.Over all difficulty will depend not only on the game design but also the type of user(new,moderate and hardcore).One of the games i played, used to fluctuate its difficulty level by injecting small and easy tricks.That used to keep the interest alive as “it makes the user happy to solve something at higher level easy”.

5.Never ignore logic and science.

 We might be playing games which is based totally on imagination but still we don’t want it act a really irrational.Give them a real world feel by following logic and science.Make them as accurate as possible and add some feedback affects or sound effects to make them real.

6.Give a fair chance to win.

Every one loves a winner and everybody loves to win a game.Thats why you play it.Some people might think that a very difficult game will make it more exciting but if you do and people are not able to solve it , will they play again ? Games are played to relax them, to diver mind and make them happy when they win.Too difficult games can make them irritated results , you loose the player.Make them happy, give them powers and points.

7.Never go over board with rewards

Don’t just keep on giving them points and make them so powerful that they feel, “hah who made this game its so easy, Let me find some other difficult game”.Make it a fair decision, give them points and take away when necessary, so they keep up with game.

8.Never ignore the story.

If you can have a story of the game you are designing, it will create an imagination in the mind of gamers.This not only will help them to get more understanding of the game but also find clues.Just make sure you story fits the game.I remember playing warcraft.It has such an awesome introduction of the 4 tribes it had, it was easy to understand some of the typical nature of those tribes and gave a strong imagination how the AI was designed.

9.Give them some secret doors and mysteries.

In some games the author purposely make some secret things.Like a secret path, some hidden doors which either can trap the user of give them a key to next stage.Make them little difficult and keep them more invisible, but give users a hint somewhere which makes them feel “Something is there, I had seen it flashing once.”

10.Long Live the game:

A lot of good adventure games become dust collections after players have solved them.Often this can be prevented or at least delayed, by a little extra effort on the part of the author.Give some of your puzzels multiple solutions.Think of imaginative ways of dying and humorous tricks for the player to try.Some adventures have even multiple endings depending on various things player has done during the course of time.
If you see yourself making mistakes like that, you might consider what i said above.Designing a good text adventure is long and frustrating but the end can be rewarding.Good interactive fiction is always in demand.I Am not a designer but thats what i felt when i played games.SO i thought why not make it into a points.SO its a user expressing all above points ….make it click.
