Hi,
I a newbie and looking to find some explanation on TileMap. I am trying to developing a game where objects keep moving in certain path
And can you tell me that to do path finding do I have to use TileMap?
Kindly help me to figure out what is the best way to implement objects moving by using path finding...
Regards
Mustafa
Hi there, what you're referring to is normally called A* (a star) algorithm.
Google it to read about it, it's not the easiest thing to implement.
If you create a tilemap, retain it, and know which color values a "walkable" tile consists of then you could implement it.
It would require a good understanding of how tilemaps works.
Hope that helps,
cheers

Hi Patrick,
I am sorry, I really didnt get anything. I am newbie of iPhone development. Ok now my issue is to implement a path finding depending upon the obstacles rather the predefined path.
Kindly put some light on this will Tilemap helps me in this regards orelse do I need to go with any other approach.

Well it's not too straight forward, it really depends on what you want to do, there are many ways.
If your characters or whatever will be able to walk everywhere, and only avoid obstacles, the use of TileMap is not necessary.
If, on the other hand, you need to have walls and bits of the "world" where the character can't walk then TileMap might be of help.
A TileMap is simply a way of displaying a large number of identical sprites, to create a big world without destroying performance.
So, it's used to display stuff on screen and not directly linked to collision checks or path finding, but you could adapt it to do so with some extra work.
You will need to look more in-depth into what a tilemap is exactly and how it works (google), and take a good look at the cocos2d examples.
Also, you would need to implement some sort of collision check, either with the integrated chipmunk or write a simplified version yourself.
Read about the A* algorithm to get a grasp on what the problems and possible solutions are.
Any other questions, here to help :)
