Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing battle games lack the ability to make game characters look more attractive during attacks, particularly when defeating stronger enemy characters.

Innovation Solution

A game processing method and recording medium that control a virtual camera to be in a predetermined position and orientation when a game character executes an attack on an enemy character, making the character look more attractive by adjusting the camera's position and orientation based on the enemy's state and type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the virtual camera follows a predetermined tracking mode during battle, then the game character can be continuously displayed, but the character cannot look attractive during attack moments

Engineering Contradiction:

Improvecontinuous display of game characterVSAvoidattractiveness of game character

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The virtual camera transitions from a static predetermined tracking mode to a dynamic mode during attack moments. The camera position and orientation are dynamically adjusted based on attack detection, allowing the character to look attractive during attacks while maintaining continuous display during normal battle states.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The camera parameters (position and orientation) are changed from fixed predetermined values to variable values during attack moments. By detecting attack execution and modifying camera parameters at these moments, the character appearance is enhanced without sacrificing continuous display reliability.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If the virtual camera is repositioned to make the character look attractive during attacks, then the character appearance is enhanced, but the camera control becomes more complex

Engineering Contradiction:

Improveattractiveness of game characterVSAvoidcamera control system

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The system performs preliminary detection of attack execution before fully repositioning the camera. By detecting the attack state in advance and triggering camera repositioning accordingly, the system simplifies control logic while achieving enhanced character appearance during attacks.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The camera control system uses feedback from attack detection to automatically adjust camera position and orientation. When an attack is detected, the system feeds this information back to the camera control mechanism, which then repositions the camera to enhance character appearance, creating a closed-loop control system.

Inventive Principle:

Principle #23Feedback

AI summary

A game processing method executed by an information processing device, the game processing method includes executing a battle between a first game character and a second game character, determining whether the second game character is able to be brought into a predetermined state by an attack in a case of receiving an instruction input to cause the first game character to execute the attack on the second game character, and controlling a virtual camera for displaying images of the first game character and the second game character such that the virtual camera is in a predetermined position and a predetermined orientation when the first game character executes the attack in a case where the second game character is determined to be able to be brought into the predetermined state.
