Solution Overview

Problem

Conventional shooting games face issues with locking mechanisms that result in unrealistic scenarios when targets move off-screen, leading to player frustration and dissatisfaction.

Innovation Solution

A method and device for continuous locking shooting that allows players to maintain a locking state by replacing locking positions on the display screen, ensuring that at least one position remains visible, and includes a game processing module to manage locking and unlocking operations based on player input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the locking position is fixed on the target object, then the locking function is simple to implement, but the locking state is lost when the target moves off-screen

Engineering Contradiction:
Improvelocking state maintenanceVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking position is made dynamic rather than fixed. When the currently locked position moves off-screen, the system automatically switches to lock a different position that remains on-screen. This dynamic adjustment maintains the reliability of locking state while adapting to target movement, resolving the contradiction between simple implementation and state maintenance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The target object is divided into multiple discrete locking positions. Instead of locking the entire target or a single fixed point, the system segments the target into several lockable positions and can switch between them. This segmentation allows the locking function to maintain state reliability by having multiple candidate positions while keeping the mechanism relatively simple.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If the guide line is extended beyond the display screen, then the locking position can be tracked, but the display becomes unrealistic

Engineering Contradiction:
Improvelocking position informationVSAvoiddisplay realism
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

Instead of extending the guide line beyond the screen boundaries (which would be unrealistic), the system inverts the approach by selecting a different locking position that naturally keeps the guide line within screen boundaries. This maintains display realism while preserving locking position information through the guide line.

Inventive Principle:
Principle #13The other way round (Inversion)

3Object-affected harmful factors

If the locking shooting is cancelled when target moves off-screen, then the display remains realistic, but player satisfaction decreases

Engineering Contradiction:
Improvedisplay realismVSAvoidplayer satisfaction
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system performs preliminary action by proactively switching to a different locking position before the current one completely disappears off-screen. This anticipatory switching maintains both display realism (guide line stays on-screen) and player satisfaction (locking state continues without interruption).

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking action is made continuous by automatically transitioning to another valid locking position when the current one becomes invalid. This continuity ensures the useful action of locking persists without interruption, maintaining player satisfaction while keeping the display realistic through proper guide line management.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method and a device for enabling continuous lock-on shooting in a shooting game. Said method comprises: firstly determining whether a player uses a shooting element displayed on a display screen to perform lock-on shooting to a lockable target object on the display screen; if the player performs lock-on shooting, enabling the lockable target object to generate at least one locked position, and enabling the shooting element to select any one of the at least one locked position to perform lock-on shooting; when the locked position in which the shooting element performs lock-on shooting leaves the display screen, enabling the shooting element to select any one of the locked positions which do not leave the display screen on the lockable target object to re-perform lock-on shooting; and when unlocking or all of the at least one locked positions leave the display screen, enabling the shooting element to no longer perform lock-on shooting; and accordingly, when any one of the locked positions of the lockable target object still locates on the display screen, enabling to maintain a lock-on shooting state for the lockable target object, satisfying the playing requirements of the player.
