    • One other thing I wanted to point out was regarding the collision detection.  I noticed that in at least one instance, my Pac-Man died when it barely touched the ghost.  I suppose you are using either hardware collision or checking the position of the sprite objects themselves.  In the original Pac-Man, they use a tile-based collision system, in which the grid is divided into tiles, and the position of a sprite is determined based on its center point.  A collision was registered if the computed "center tile" for Pac-Man and a ghost matched.   Of course, this is not strictly necessary for your game, but it would be really cool for Maximum Pac-Man Retro Accuracy.   It shouldn't be too hard -- in fact, this collision system was chosen because it is stupidly simple.  Here are a few things to consider: Tiles in the original Pac-Man are 8x8 pixels and sprites are 16x16 pixels.  That means that tiles are 1/2 the size of a sprite.  For the Intellivision, we can make tiles 4x4 to go with 8x8 sprites.  (That's how I do it in Christmas Carol, er, my port of Pac-Man). In Pac-Man, tiles are centered on the path, like this: On the Intellivision, it would look something like this: On the Intellivision, if the background cards are 8x8 pixels, but the "virtual tiles" are 4x4 and centered on a background card, that means that they are offset from a card by 2 pixels from the origin, like this: Therefore, the position of a "virtual tile" is the pixel position of a background card plus two pixels: vtileX = ( column * 8 ) + 2 vtileY = ( row * 8 ) + 2 The center of an Intellivision sprite is 4 pixels offset from its origin, like this: Therefore, we can compute the center of a sprite like this: centerX = posX + 4 centerY = posY + 4 To check collisions on tiles, you can do something like this: ' vtileOffsetX = 2 ' vtileOffsetY = 2 ' Compute Pac-Man's virtual tile position pacmanTileX = (pacmanPosX + vtileOffsetX) / 4 pacmanTileY = (pacmanPosY + vtileOffsetY) / 4 ' Compute Ghost's virtual tile position ghostTileX = (ghostPosX + vtileOffsetX) / 4 ghostTileY = (ghostPosY + vtileOffsetY) / 4 ' Check collision If (pacmanTileX = ghostTileX) And (pacmanTileY = ghostTileY) Then ' Collision!!! End If   In fact, that is an IntyBASIC translation of the code I use in Christmas Carol. :)        -dZ.

    • Just a guess, but you might be thinking of the modern game Ridiculous reality, rather than the Alternate Reality RPG series from the 80s.      Both of these are amazing games.

    • Because I am finding AGSP threads all over the forum(in Dedicated Systems and Atari General sections) it should have one place for everything, not scattered, if it was me I would and I have on my forum, AGSP is in one place only. I posted this here so you see it, once you have put it in About forum... AGSP is quite popular and is a officially licenced product by Atari for My Arcade so should have its own section. Like this if you agree...
