“The hardware lets you draw about half a screen off each side, which helps considerably. “We did an end run around the problem,” said Mr. Rotberg had to go to his graphic designer, Roger Hector, who also helped define the game play, to ask: “Could you do the same thing in less lines, less vertices?”Īlthough Battlezone does not deal with the hidden-line problem, it does use diminished brightness to indicate distance, and, like any vector-drawing system, it most cope with the problems of clipping-that is, deciding what objects are on the screen and what to do about objects that are partly on the screen and partly off. Even so, controlling the number of objects on the screen stretched the abilities of the three microprocessors, and Mr. Rotberg said, was involved in “figuring out how to organize the data.”īecause Battlezone is a vector game, objects consist simply of points connected by lines, rather than entire filled regions, as a raster game would have. Much of the early work in designing Battlezone, Mr. To bring the problem within reach, the game is restricted to movement on a horizontal plane, reducing the matrix from 4 by 4 to 2 by 2. What the math box in Battlezone does is solve the matrix equations for vanishing-point perspective for all of the objects on the screen. “Quite often it wasn’t worth going off and doing something else-you just waited for the math box to finish.” The display generator and the game microprocessor operated either in parallel or in sequence with the others. Battlezone, a first-person tank game, was made possible by a vector display unit used by Atari Inc., Sunnyvale, Calif., in Asteroids, which came out the previous year.Įven with the vector generator, according to Videa’s Ed Rotberg, who wrote computer code for the game, Battlezone required three microprocessors: a 6502 to control the game play, a custom processor for the display, and another, built from 2901 bit-slice processors, for the mathematics. It is also highly recommended to install the VSR mod for bz2, located at: bz2maps.Three-dimensional displays first appeared on computer screens in the 1960s, and very large machines could manipulate those images in real time, but it was not until 1980 that a video-game player could maneuver at will through an imaginary landscape, wreaking havoc until brought to an untimely end by enemy tanks. These are needed to run the game, and is part of why some people on this chat are saying they are missing certain. **IMPORTANT** The patch installer will also ask you to install a few dependencies such as Microsoft's C++ redistributable. To install the latest patch, simply double click the downloaded patch, make sure that the directory correctly i.e - tell the patch where your bz2 folder is located. The latest patch will include a no cd crack, so you can just launch bzone.exe whenever you want (or create a shortcut of it on your desktop to launch from) Download and Install the latest patch - 1.3 6.5 from Extract all of the files into a normal folder (name it bz2 or whatever you want)Ĥ. iso file using a program such as 7zip or winrarĪgain, you can learn how using the first link that was suppliedģ. Convert the downloaded MDF and MDS files into an ISOĢ. **NOTE: The patch that comes with the download is obsolete**ġ. Please read all of this in order to be sure that the game will run correctly *For those of you who simply want to play the game off of the computer*
