ABSTRACT:
A process is disclosed for displaying a plurality of objects on a video display screen. A video computer system (VCS) includes a microprocessor unit (MPU), a television interface adapter (TIA) having first and second high-resolution player graphics capabilities, a video display screen in the form of a television set, operator controls, and a video game cartridge in the form of read-only memory (ROM) which contains digital program information including the steps of the present process stored in preselected address locations. The present process uses a first set of data for a high-resolution player graphics original and multiple resets of an associated player graphics register to display greater than three copies of the player graphics original on a single given horizontal scan line of the video display screen. As a result, the remaining high-resolution player graphics original is available to create other high-resolution player graphics copies on the same series of horizontal scan lines. The copies of the player graphics original can be selectively removed from the video display screen. A second embodiment of the present invention includes a process for using sets of data for the two high-resolution player graphics originals and multiple resets of respective associated player graphics registers to create greater than two graphically different high-resolution player graphics copies along a single given series of horizontal scan lines.
