==Playing field and scoring== <gallery perrow=4 heights=250px widths=250px> File:46318 - 1998 game materials.png|Top-down view of the field before a match [https://www.frcarchive.com/index.php?q=post/view/46318] File:46319 - 1998 game materials.png|Field setup for the one-on-one rounds [https://www.frcarchive.com/index.php?q=post/view/46319] </gallery> The field is a carpeted hexagon In the center of the field is an 8 foot hexagonal Central Goal. Extending outwards and upwards from the Central Goal are the ladder-like Rail Goals. The rail has two pipe dividers that divide it into thirds. Centered on the sides of the field that are not supporting the outer end of the Rail Goals are the 5 foot wide Interaction Zones and Human Player Areas. The Interaction Zone is the three foot deep area where both robots and human players can interact with balls. Human players could not apply weight to this area but could reach or lean over it to grab balls in the interaction zone or load them into a robot. The Human Player Area behind the interaction zone and extending another three feet is where human players are allowed to stand and throw or load balls. Human players must wear safety helmets with attached face shields. Only three balls of any color can be kept in the player station at one time (although a robot can be holding additional balls inside the volume of the Interaction Zone). Driver stations are positioned off-center on the Rail Goal sides of the field near their corresponding human player areas. Three robots in the red, white, and blue positions play simultaneously in the seeding rounds and earlier rounds of playoffs, with one on one matches later on. Robots can start in any orientation within the designated 4' by 4' starting area but cannot touch the center goal, rails, or field border. Each team has nine matching color balls. Three balls begin in their Interaction Zone, three more begin on the floor, with three lines of three balls, one of each color, between where the robots begin. One ball of each color begins scored on each level of the Rail Goals, with one ball of each color on each Rail Goal. The Rail Goal extending over each team's starting are begins with one of their balls in the lowest section, with the rail counterclockwise around the field starting with one of their balls in the middle section, and their third pre-scored ball in the highest position of the Rail Goal clockwise around the field. In one-on-one playoff matches, robots play in the red and blue positions, with no white balls on the field. Scoring begins when all balls in motion when a match ends have come to a rest (or upon a referees' decision). Balls in the highest third of the Rail Goals closest to the outside of the field are worth three points. Balls on the middle "rung" are worth two points, and balls in the central third of the Rail Goals are worth one point. A ball must be contacting both side rails of a Rail Goal with the center point of the ball above the place of the upper edge of the rails to be counted. Balls scored in the central goal are worth no points themselves but each ball doubles the score from the balls on the Rail Goals. A ball is considered scored in the central goal if the central plane of the ball is below the top rim of the goal and within the outside edge of the goal. Tiebreaks are determined first by the team with the least penalties or warnings during the match, then the team with the most balls on the Rail Goals, then the team with the highest (or next highest, in the case of a tie) ball on the ladders, then by number of balls in the central goal, then the team with the highest ball in the central goal, and finally the team with the most opponent balls in their player station. Each match lasts two minutes. The control system is automatically enabled and disabled when matches begin and end. ===Game strategy=== Because robots started under the three-point ball of one of their opponents (or their only opponent in the 1 on 1 matches), a common opening move was to extend upwards and knock the three-point ball off the rungs. The bulk of match play often focused on human players and robots trying to get as many point doublers into the center goal as possible to ensure a good stackup of doublers before worrying about the balls on the point rungs which were more vulnerable than balls scored in the goal. Robots could pass balls of an opponent's color to their human player both to take them out of play and to give the human player ammunition to toss at opponent's balls on the rungs to try to descore them. Some robots were built to squeeze the balls between the rungs of the goal and ladders to make it harder to knock them out of position, and some human players got good enough at throwing the balls with enough force that they could shoot them in through the pipes forming the sides of the goal. Towards the end of the match, play would shift towards more offense on the rungs, with robots often adding a ball to a three-point rung and then camping over it to protect it from the human players or other robots. Human players would also shift focus towards throwing any remaining balls at high-value opponent balls on the rungs, trying to knock them off and leave them with zero points to double from the center goal. Because of the way the double elimination tournament was structured, the one on one on one elimination rounds would sometimes see two teams focusing on a single harder opponent to try to knock them out before the one on one playoffs began. This two-on-one strategy is what caused [[frc47|team 47]], heavily favored to win the championship after three regional wins with the first swerve drive, to be eliminated at [[1998cmp|Nationals]].
