Create a game similar to pacman.

[iSDK]

Hi,

I want to make a game that will be similar to pacman from scratch. I don't want to use a games engine either, just plain ol' xcode.

Basically the game would consist of a map that fits the screen, walls within the map, food, enemies and a player.

I just wanted to know what the best way forward would be. I plan on creating the map first, and then doing everything else after that. Where should I begin?

Thanks

Personally,
I would just use cocos2d.

Or you should draw walls and the player first using OpenGL or quartz2D.

Ok, but how could I determine when the walls were touched?

I would suggest using a tilemap. A tilemap is basically an array (or at least a collection of some sort) of individual tiles that make up a level. You can use a tilmap to simplify the creation and drawing of your level. A tilemap can also be used to greatly simplify the collision detection in your game. Just search around about tilemaps and their should be a lot of resources.

Really?

PacMan is a circle. In the game, walls were either vertical (constant X) or horizontal (constant Y), and you can model them (if not, in point of fact, DRAW THEM) as rectangles.

# Case 1 - vertical wall and Xpacman < Xwall

CGPoint P2W -> CGPointMake( Xpacman + Rpacman/2, Ypacman)
if CGRectContainsPoint( rctWall, P2W) then collision

# Xpacman = X coord, center of PacMan
# Ypacman = Y coord, center of PacMan
# Rpacman = PacMan radius
# Xwall = X coord, center of wall

Won't save you if you rez PacMan __IN__ a wall deliberately, but I'll assume you won't do anything that foolish. Remaining cases left as exercise for student.

DISCLAIMER: not real code ... I get paid for real code. The functions are real, though.

hehe, im a developer not a game developer. This is new!!

If it would help you there is a very realistic pacman game written in flash you can use it as a model to develop your own.

I am trying to construct a same model like Pacman and this game is very realistic and i am now trying to develop it own.
