Subject: [stella] Game project From: Tennessee Carmel-Veilleux <veilleux@xxxxxxxxx> Date: Thu, 18 Jun 1998 21:17:56 -0400 |
Hello, I have a game project in mind, but I can't seem to figure out a way to do it with the rather primitive Atari TIA chip :) I involves making a fullscreen or semi full screen (like 160 FULL horizontal TV lines), that would be made using the playfield graphics. Example: +--------------------------------+ | | |#########################| |#########################| |#########################| |#########################| |#########################| +--------------------------------+ But I some of the square might be missing... I would store the playfield line by line in 5 bytes (I want 40 horizontal positions, which can be done with playfield graphics) using Bit per bit encoding since squares can be either on or off (1 or 0). The problem is : although everything is just one color, the playfield graphics must be either reflected or repeated, which is really not what I want :) I anyone knows how to do it (I think it involves changing the data in the middle of the scanline), then I would like to know how. Also, I want to know if it is possible to move a sprite more than 8 units either left or right between each frame (like at frame 1, it's at position x=0, and frame 2, it's at position x=120)...
