Solution Overview

Problem

Existing virtual shooting games lack diversity in control methods for virtual throw props, particularly in causing continuous damage to enemies, as traditional props like grenades only affect when they hit and do not provide sustained damage.

Innovation Solution

A virtual prop control method that displays a target virtual throw prop in a game application, allows the first virtual operation object to throw the prop upon detecting a throw operation, sets a target region as a damage detection zone where the prop falls, and continuously reduces the hit points of a second virtual operation object within that zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a traditional grenade prop is used to cause instantaneous damage, then the damage effect is strong at the moment of impact, but the damage cannot be continuous or sustained

Engineering Contradiction:
Improveduration of damage effectVSAvoiddamage output efficiency
Core Design Contradiction:
Duration of action of moving objectVSProductivity

Solution Approach 1:

The patent transforms the static, instantaneous damage model into a dynamic, continuous damage model. The virtual prop no longer deals fixed damage at impact but continuously reduces hit points over time based on proximity to the impact point, enabling sustained damage effects that adapt to enemy movement and positioning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements continuous damage action by making the prop's harmful effect persist over a duration rather than occurring instantaneously. The damage calculation continuously executes within a time window after impact, ensuring sustained useful action against targets that remain in the damage zone.

Inventive Principle:
Principle #20Continuity of useful action

2Adaptability or versatility

If a grenade causes instantaneous damage upon impact, then the control method is simple, but the diversity of control manners is limited

Engineering Contradiction:
Improvediversity of control mannersVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes key parameters of the damage model: from fixed instantaneous damage to variable continuous damage, from binary hit/miss to gradient-based damage zones, and from single-timepoint effect to time-window-based effect. These parameter changes enable diverse control manners while maintaining manageable system complexity through standardized calculation frameworks.

Inventive Principle:
Principle #35Parameter changes

AI summary

The disclosure provides a virtual prop control method and apparatus, a storage medium, and an electronic device. The method includes displaying a target virtual throw prop controlled by a first virtual operation object in a target game application. The method also includes controlling the throwing of the target virtual throw prop based on a target throw operation. The method also includes setting a target region at which the virtual throw prop is thrown as a damage detection region, with the damage detection region configured to reduce hit points of at least one target virtual operation object located in the damage detection region. Based on a second virtual operation object being included in the at least one target virtual operation object and entering the target region, the method also includes reducing hit points of the second virtual operation object.
