Abstract
A system for rapid processing of the data records of many moving and nonmoving objects on a playfield only part of which is displayed and for determining collisions between objects, machine searching a linked list of the records organized by approximate position on the playfield implements the search function, is provided to continue searching for the next object which is to be visible while the graphic data from a previously found object is being loaded into a line buffer. Slips pointing to the first objects on the list for the current scan line speed up the search process. The collision detect process is speeded up by only checking the nearest neighbors on the playfield in the path of movement and by organizing all the moving and nonmoving objects on the playfield in a two dimensional array mapped to the approximate position of display of the object on the playfield.
