Description

Method, apparatus, device, storage medium and program product for controlling special effect patch Technical Field The present application relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, a storage medium, and a program product for controlling a special effect patch. Background In virtual scenes such as games, in order to enhance visual impact and immersion of a screen, developers often set special effect tiles such as shock waves, knife light, environmental dust, and the like at positions close to a screen (virtual camera). One of the core design goals of such pre-screen special effects is to fill specific areas of the screen stably and plump at different viewing angles and states to achieve the desired artistic performance. In the related art, when the angle of view of the virtual camera is fixed, by presetting the distance between the special effect patch and the camera, it is possible to make it exhibit a stable and properly sized visual effect on the screen. However, in practical application scenarios, in order to create a specific dramatic effect, such as highlighting a Boss unit or switching the viewing angle, the viewing angle of the virtual camera often needs to be dynamically adjusted. Once the angle of view changes, the display proportion of the original special effect face piece on the screen changes according to the perspective principle, so that unexpected enlargement or reduction phenomenon occurs, and the current screen window cannot be continuously and perfectly adapted, thereby destroying the consistency and the integrity of visual manifestation. Disclosure of Invention In view of the above, the present application provides a method, apparatus, device, storage medium and program product for controlling a special effect patch to solve the problem of unstable special effect display effect. In a first aspect, the application provides a control method of a special effect patch, which comprises the steps of obtaining a first distance between a target special effect patch and a virtual camera, a first view field angle corresponding to the virtual camera and a reference height corresponding to the target special effect patch, obtaining a changed second view field angle in response to the change of the first view field angle, determining a second distance between the target special effect patch and the virtual camera under the second view field angle based on the second view field angle and the reference height, and controlling movement of the target special effect patch based on the offset between the second distance and the first distance. In an alternative embodiment, obtaining the reference height corresponding to the target special effect patch includes determining the reference height corresponding to the target special effect patch based on a positional relationship between the first distance and the first field of view angle. In an alternative embodiment, determining the reference height corresponding to the target special effect patch based on the positional relationship between the first distance and the first field of view angle includes obtaining a first visual parameter value characterized by a first tangent value of the first field of view angle, and determining the reference height of the target special effect patch based on a fusion result of the first distance and the first visual parameter value. In an alternative embodiment, determining a second distance of the target special effect patch from the virtual camera at the second field of view angle based on the second field of view angle and the reference height includes obtaining a second visual parameter value characterized by a second tangent to the second field of view angle, determining a ratio between the reference height and the second visual parameter value, and characterizing the second distance as the ratio. In an alternative embodiment, controlling the movement of the target effect patch based on the offset between the second distance and the first distance includes determining a movement direction of the target effect patch based on the offset between the second distance and the first distance, and controlling the target effect patch to move a third distance in the movement direction, the third distance being the same as the offset. In an alternative implementation, whether the target special effect surface patch comprises a plurality of sub special effect surface patches is judged, when the target special effect surface patch comprises the plurality of sub special effect surface patches, a first target distance between each sub special effect surface patch and the virtual camera and a first target reference height corresponding to each sub special effect surface patch are obtained, a second target distance between each sub special effect surface patch and the virtual camera under a second view field angle is determined in response to the change of the first view fie
