Solution Overview

Problem

Existing 3D shooting games lack comprehensive game replay images, making it difficult for players to accurately review and strategize for future rounds, as they do not provide separate replays for each round or detailed game progress.

Innovation Solution

An apparatus and method that generates and provides replay images in a 2D plan view, marking player movements and interactions, allowing players to review each game round individually and at their convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional 3D shooting games provide no replay images or only highlight images, then the device complexity is reduced, but the measurement precision of game progress review deteriorates

Engineering Contradiction:
Improveaccuracy of game progress reviewVSAvoidreplay system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The game match is divided into multiple game rounds, and separate replay images are generated for each round. This segmentation allows players to review specific rounds in detail without overwhelming complexity, as each replay image focuses on a single round's progress rather than attempting to show the entire match at once.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system generates two-dimensional plan view copies of the three-dimensional game space to create replay images. These 2D representations simplify the complex 3D game environment into an easily reviewable format that shows player positions and movements without requiring the full complexity of the original 3D rendering system.

Inventive Principle:
Principle #26Copying

2Loss of information

If separate replay images for each game round are generated and provided, then the information completeness of game review is improved, but the loss of time for replay generation and transmission increases

Engineering Contradiction:
Improvecompleteness of game review dataVSAvoidreplay generation and transmission time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system generates replay images for each game round immediately when that round ends, rather than waiting until the entire match is complete. This preliminary action ensures that replay data is prepared in advance, reducing the time delay when players want to review previous rounds and allowing continuous playback without waiting for match completion.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If detailed replay images showing all player movements are provided, then the measurement precision of game analysis is improved, but the quantity of data to be processed and transmitted increases

Engineering Contradiction:
Improvedetail accuracy of player movement trackingVSAvoidvolume of replay data
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system extracts only the essential information needed for game review - specifically player positions and movement trajectories - from the complete game data. By focusing on these key elements and representing them in a simplified 2D plan view format, the system provides detailed movement tracking without generating excessive data volume.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Disclosed herein are an apparatus and method for providing game replays. The apparatus for providing game replays includes: storage configured to store a game log for each game round of a game match including a plurality of game rounds that are performed sequentially; a controller configured to run the game round by providing a game screen of a three-dimensional game space to a plurality of players participating in the game match and also receiving control commands for characters from the plurality of players, and to, when the game round ends, generate a replay image showing changes in the location of a character corresponding to each of the plurality of players on a two-dimensional plan view of the three-dimensional game space based on the game log of the game round; and an input/output interface configured to provide the replay image to the plurality of players.
