I Bought the IOS license for USD400

So I start to get a little bit boring just doing the unity thing and I want to test my little game on my iPhone so I just paid the USD400 to buy the IOS license and now i am trying very hard to follow the tutorial below

http://wiki.unity3d.com/index.php?title=IPhone_Getting_Started_with_the_UnityRemote


It is very very very hard indeed and hopefully I can get it done

after 5 minutes of following the instruction

it said

you need to pay $99 to enroll in iPhone Developer Program to use unity remote

oh my god

need more money

well, i guess since I already walk so far, I need to pay again

ok, after paying USD99 for the iPhone developer program

I need to setup the certificate, which is super hard for me, anyway, below is the video how to do it

http://www.youtube.com/watch?v=HlRI30F6-Ek

today progress: Character can now enter 3 different building

So I have created 3 building and the character can run into it

Today Progress: Changing cloth for my character

So this is the first attempt to change cloth for my character as in the video

As you can see, i try to make 3 button, shirt, pants, hair,

when i click shirt, i got 5 option to change the shirt

when i click pants, i got another 5 option to change the pants

for the noob that wondering how I accomplish this, below is the stuff that i used

1. OnGui function
- write a new script with OnGui function then add 3 button to the screen, then when pressing any of the button, show a new selectionGrid with 5 item , then you can drag 5 different texture into your selection grid
- when clicking the item on the grid, just change the texture of your character body
-below is sample code

GridValue = GUI.SelectionGrid(Rect(200,200,400,400),GridValue, ShirtGrids, 5); mySkinnedMeshRenderer.materials[8].mainTexture=ShirtGrids[GridValue];

2. Blender UV mapping
- when you create your character on blender, you need to create UV mapping for your character
- you need to mark Seem on your character manually, then select the body part to unwrap it
- you can then export you uvmapping to .png file and draw your shirt or pants on it

any question feel free to ask
