tiles

Not sure how to approach this problem. Basically, I want a Pixel -> Tile representation of a 400x400 window. Each coordinate on the screen, e.g 120x300 should be part of a tile. My smallest sprite is 4 pixels, so we can say that 1 tile = 4 pixels. The player and enemy sprites are all 20 x 20, so each player/bad guy will occupy 5 tiles. Then I want to use this Map class to: Retrieve the x/y coordinates of a player/monster sprite by suppling the index/id of the tile. Knowing where the boundaries are, so it doesn't move the sprite beyond 400x400 , thus hiding it. Collision detection, knowing

I am working on an iPhone / iPad app that is using semi-transparant tiled map overlays via MKMapView and MKOverlay. I want users to be able to zoom in deeply into the maps, but the resolution of my map overlays only goes to level 6. I do not want to limit zooming. But... If a user zooms "too far" and then scrolls to a new tile, if they are zoomed deeper than the tree of overlay tiles, my overlay is not drawn. I want the overlay to draw even when the user is zoomed in deep. Are there any best practices to achieve this? The two options I have come up with: 1) Set a limit on how far users can

If you know the answer, would apprecite if you tell me how to use freemarker with it. If don't even than I accept the answer if you solve my problem to make the code work.

EDIT: Wrapped the example map in a code block so the formatting is correct. Ok, I'm trying to write an extremely simple A* algorithm over a hexagonal grid. I understand, and can do the A* portion. In fact, my A* works for square grids. What I can't wrap my brain around is finding neighbors with hexagons. Here's the layout for the heagonal grid 0101 0301 0201 0401 0102 0302 0202 0402 etc, etc So, what I need help with is writing a Hexagon class that, given it's hex coordinates, can generate a list of neighbors. It needs to be able to generate neighbors which would 'fall off' the grid (like 0000

I'm trying to make (figure out how to..) a 2d platformer in XNA. I know how to create a tile grid and how to perform collision detection. I perform collision detection on the 9 bounding tiles of the player, but I'd like to know if there's a better way to perform collision detection. I've read Braid doesn't use tiles but pieced images or something, how do you perform collision detection on those? and is that better than using tiles? Assuming you don't mind using a third party tool to do the majority of the work for you, you may be better off using something like Box2D for C#. http://www.box2d
