Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, a method of generating a collision object according to an embodiment of the present invention will be described.
The generation method of the collision object provided by the embodiment of the invention can be applied to electronic equipment in communication connection with the touch screen. The touch screen may be included on the electronic device or may be independent of the electronic device. In a specific application, the electronic device may be various, and specifically, the electronic device may include a desktop computer, a portable computer, an internet television, an intelligent mobile terminal, a server, a wearable intelligent terminal, and the like, which are not limited herein, and any electronic device that can implement the embodiment of the present invention belongs to the protection scope of the embodiment of the present invention.
As shown in fig. 1, a flow of a method for generating a collision object according to an embodiment of the present invention may include:
s101, when a generation instruction of a collision object is detected, touch point information of a plurality of touch points generated on a touch screen and width information of a line used for drawing the object are acquired.
In a particular application, the generation instruction of the impact object may be various. By way of example, the generating instructions for the impacting object may include: information for indicating the start of a virtual game, information for indicating the opening of a table rigid body collision special effect, and the like. Also, the detection method of the generation instruction of the virtual object may be various. For example, a client having a collision object generation requirement may be monitored for generating a collision object generation instruction. The client having the collision object generation requirement may specifically be an electronic device as an execution subject of the present invention, or an App (Application program). Alternatively, it may be detected whether a generation instruction of the impact object is received, for example.
The touch points generated on the touch screen may be specifically points generated on the touch screen by the touch and sliding of a finger in the process that the finger slides on the screen until the finger leaves the touch screen when the finger touches the screen. The touch point information is information indicating a position of the touch point on the touch screen, for example, a position coordinate of the touch point on the touch screen. The manner of acquiring the touch point information of the plurality of touch points generated on the touch screen may be various. For example, the touch point information of a plurality of touch points may be read from the electronic device by using a preset script, or the touch point information of a plurality of touch points transmitted by the touch screen through the communication connection may be received.
The collision object is a virtual object, and a line is required for generating the collision object. Therefore, it is necessary to acquire width information of a line used when drawing an object. The width information of the line used when drawing the object may be obtained in various ways. For example, the line width of the collision rigid body in the physics engine may be read as the width information. Alternatively, for example, when the physical engine is included in the game engine, the width of a line used by a built-in drawing component of the game engine may be used as the width information.
Any means of generating an instruction to collide with an object, generating an instruction to detect a collision object, and acquiring touch point information and width information of a line used when drawing an object may be used in the present invention, which is not limited in this embodiment.
S102, obtaining the shape information of the collision object based on the width information and the touch point information.
In specific application, the touch point information of a plurality of touch points can indicate a sliding track of a finger on the touch screen, and the sliding track can reflect the user-defined requirement of a user on a collision object; in addition, it is necessary to use a line having a line width equal to the width information when generating the virtual object. Therefore, in order to ensure that a custom collision object is subsequently generated, shape information of the collision object may be obtained based on the width information and the touch point information.
For easy understanding and reasonable layout, the following embodiment of fig. 2 of the present invention specifically describes a process for obtaining shape information of an impact object based on the width information and the touch point information.
And S103, generating a collision object corresponding to the shape information by using a preset physical engine.
In a specific application, the physics engine is a component for simulating a physical phenomenon in a virtual scene based on a real-world physical law, and the physical engine can be various. Illustratively, the physics Engine may be a physics Engine in a game Engine, hawok, a PhysX physics Engine, and ODE (Open Dynamics Engine), among others. The physical engine can simulate physical phenomena in a virtual scene, and the collision object is a virtual object for generating the physical phenomena of rigid body collision with a certain target object; therefore, in order to facilitate the subsequent rigid body collision and improve the generation efficiency of the collision object, the collision object corresponding to the shape information may be generated by using a preset physical engine.
The generating of the collision object corresponding to the shape information by using the preset physical engine may specifically include: and transmitting the shape information into a preset physical engine so that the physical engine generates a collision object corresponding to the shape information. Also, the collision object corresponding to the shape information may be various. For example, the collision object corresponding to the shape information may be a collision object having a shape reflected by the shape information and the same size as the shape. For example, the shape reflected by the shape information is a pentagon, the shape of the collision object is the same as the shape, and the size is the same as the pentagon reflected by the shape information. Alternatively, the collision object corresponding to the shape information may be, for example, a collision object having a shape reflected by the shape information and having a size adapted to the size of the display window. The physical engine can adjust the size of the collision object according to a preset reduction or enlargement ratio, wherein the preset reduction or enlargement ratio is a ratio set according to the size of the display window.
In the scheme provided by the embodiment of the invention, when a generation instruction of a collision object is detected, touch point information of a plurality of touch points generated on a touch screen and width information of lines used for drawing the object are acquired; further, based on the width information and the touch point information, shape information of the colliding object is obtained, and the colliding object corresponding to the shape information is generated. Therefore, the collision object with the shape corresponding to the track formed by the touch points is generated by using the touch point information of the touch screen, and the collision object can be ensured to have the shape customized by the touch points and is not limited to the self-fixed shape of the physical engine. Therefore, the scheme can generate the self-defined collision object in the rigid body collision of the virtual scene.
Optionally, after the collision object corresponding to the shape information is generated by using the preset physics engine, the method for generating a collision object according to the embodiment of the present invention may further include the following steps:
inputting the object identification of the collision object into a collision attribute interface of a rigid body component of a physical engine, and adding collision attributes to the collision object; the collision property is a property that affects the collision effect of a rigid body collision.
The collision attribute added to the colliding object is an attribute that can affect the collision effect of the rigid body collision, and the attribute may be various. Exemplary collision attributes may include: the collision elasticity, whether the collision is influenced by gravity, the friction coefficient and the like. The rigid body component of the physics engine provides different impact property interfaces for use corresponding to different impact properties. Therefore, according to the specific requirement for the collision attribute, the object identifier of the collision object can be input into the corresponding collision attribute interface, so that the collision attribute corresponding to the collision attribute interface is added to the collision rigid body with the object identifier.
In this optional embodiment, a collision attribute interface of a rigid body component of the physical engine is used to add a collision attribute to a collision object, and when a customized collision object is generated, the diversity of collision effects can be increased by adding the collision attribute.
Optionally, the number of the collision objects is multiple;
after the collision object corresponding to the shape information is generated by using the preset physics engine, the method for generating a collision object according to the embodiment of the present invention may further include the following steps:
for each collision object, obtaining the priority of the collision object according to a preset priority rule and/or the generation sequence of the collision object;
and aiming at each collision object, searching the object identification corresponding to the priority of the collision object from the corresponding relation between the prestored object identification and the priority, and marking the searched object identification for the collision object.
The preset priority rule may be a rule for defining an order in which the plurality of colliding objects collide with the rigid body. For example, in a fishing game, the preset priority rules may include: in a rigid body collision with the water surface, the priority of the fishhook is higher than that of the fish: the fishhook firstly collides with the water surface in a rigid body mode, and then the fish collides with the water surface in a rigid body mode. When the priorities of the collision objects are obtained, the priorities of different collision objects can be determined according to a preset priority rule. Alternatively, the order of generation of the colliding objects is regarded as the priority of the colliding objects. Alternatively, the priority of the colliding object may include: the priority of rigid body collision and the hierarchy of storage, wherein the hierarchy of storage is used for indicating the depth of the collision object in the storage directory, and the highest hierarchy is stored in the root directory. At this time, the priority for performing a rigid body collision may be determined for the colliding object according to a preset priority rule, and the hierarchy for storing may be determined for the colliding object according to the generation order of the colliding object.
Illustratively, the correspondence between the pre-stored object identifiers and the priorities includes: the object identification CO1 corresponds to the priority CP1, and the object identification CO2 corresponds to the priority CP 2. In the virtual fishing game, the priority of the collision object fish hook is priority CP1, and the priority of the collision object fish is priority CP 2. Thus, object CO1 is marked for the collision object fish hook and object CO2 is marked for the collision object fish. In managing the colliding object, since the priority is associated with the mark of the colliding object, the colliding object fish hook having the object mark CO1 may collide with the rigid body of the water surface first, and then the colliding object fish having the object mark CO2 may collide with the water surface.
In the present alternative embodiment, in managing a plurality of collision objects, the priorities of the collision objects are directly associated with the identifications of the collision objects. Based on the above, when the collision objects are managed at each time, the collision objects can be directly managed according to the identifiers, so that the increase of the searching times caused by searching the priorities according to the identifiers is reduced when the identifiers of the collision objects are only used for distinguishing different collision objects, and the management efficiency of a plurality of collision objects is improved.
As shown in fig. 2, a flow of a generation method of a collision object according to another embodiment of the present invention may include:
s201, when a generation instruction of a collision object is detected, touch point information of a plurality of touch points generated on the touch screen and width information of a line used for drawing the object are acquired. Wherein the touch point information includes: the position coordinates of the touch point on the touch screen.
The above S201 is similar to S101 of the embodiment of fig. 1 of the present invention, except that the touch point information in S201 includes: the position coordinates of the touch point on the touch screen. For the same parts, detailed description is omitted here, and the detailed description is given in the above description of the embodiment of fig. 1 of the present invention.
S202, calculating the length of a connecting line between two adjacent touch points in the plurality of touch points by using the position coordinates of each touch point.
In a specific application, the position coordinate of each touch point is the coordinate of the touch point in a two-dimensional coordinate system of the touch screen, and in a plurality of touch points, two adjacent touch points are touch points with adjacent position coordinates. Therefore, the position coordinates of two adjacent touch points can be input into a distance formula between the two touch points, and the connecting line length between the two adjacent touch points can be obtained.
S203, for each link length, determining a rectangular area with the link length as long and the width information as wide.
And S204, aiming at each rectangular area, obtaining vertex coordinates of four vertexes of the rectangular area by using the width information and the position coordinates of the two touch points for obtaining the rectangular area.
And S205, taking the vertex coordinates of all the obtained rectangular areas as the shape information of the collision object.
For example, as shown in fig. 3, in an application scenario in which a target object 301 is caused to fall into a prop 303 by colliding with a rigid body of a collision object 302, the collision object 302 may be regarded as a virtual object obtained by connecting position coordinates of a plurality of touch points. Also, since the line used for the link has a width, it is necessary to determine a rectangular region having the link length as a long length and the width information as a wide width for each link length by step S203 after calculating the link length between two adjacent touch points among the plurality of touch points by step S202. For example, the enlarged outline of a part 3021 of the impact body 302 is a rectangular area in which the link length is long and the width information is wide.
After the plurality of rectangular regions are determined, the shape of the collision object to be finally generated is defined due to the vertex coordinates of the four vertices of each rectangular region; therefore, in order to obtain the shape information of the collision object, the vertex coordinates of the four vertices of each rectangular region may be obtained by step S204 using the width information and the position coordinates of the two touch points used to obtain the rectangular region; further in step S205, the obtained vertex coordinates of all the rectangular regions are taken as the shape information of the colliding object. In order to facilitate understanding of a specific manner of acquiring the coordinates of the four vertices of the rectangular area, the rectangular area 3021 will be described as an example.
In the rectangular area 3021, the touch point t1 and the touch point t2 are located at the middle position of the width of the rectangle, and the length of the rectangle is the link length obtained in step S202. Therefore, the abscissa in the position coordinates of the touch point t1 may be taken as the abscissas of the two vertexes near the touch point t1, and the difference between the ordinate in the position coordinates of the touch point t1 and one-half of the width information may be taken as the ordinate of the lower vertex in the two vertexes near the touch point t 1; the sum of the ordinate in the position coordinate of the touch point t2 and one-half of the width information is taken as the ordinate of the upper vertex of the two vertices near the touch point t 1. Similarly, the vertex coordinates of two vertices near the touch point t2 can be obtained in the same manner using the position coordinates and the width information of the touch point t 2.
And S206, generating a collision object corresponding to the shape information by using a preset physical engine.
S206 is the same as S103 in the embodiment of fig. 1, and is not repeated herein, for details, see the description of the embodiment of fig. 1.
In the embodiment of fig. 2 of the present invention, the shape information of the collision object is determined by using a plurality of rectangular areas related to the width information of the touch points and the lines used in drawing the object, so that the generation of the custom collision object is realized.
Optionally, the obtaining of the touch point information of the multiple touch points generated on the touch screen specifically includes the following steps:
and reading touch point information of a plurality of touch points meeting a preset touch point interval condition from a plurality of touch point information recorded by the electronic equipment by using a preset script.
The preset touch point interval condition is a condition for ensuring that the interval distance between every two adjacent touch points on the touch screen is equal to the preset distance in the plurality of touch points corresponding to the read touch point information.
In specific application, the larger the number of touch point information is, the smoother the lines on the collision object generated based on the touch point information are relatively; the smaller the number of touch point information is, the more obvious the crease exists in the line on the collision object generated based on the touch point information later. For example, as shown in fig. 4, in an application scenario where a customized collision object 402 performs a rigid body collision with a virtual apple 401 as a target object, so that a collision effect of the virtual apple 401 by the rigid body collision falls into the mouth of a virtual animal 403, on the collision object 402, the number of touch point information corresponding to a line 4021 is smaller than that of touch point information corresponding to a line 4022, and therefore, a fold of the line 4021 is more obvious than that of the line 4022, and the line 4022 is relatively smooth. In the preset touch point interval condition, the larger the preset distance is, the less the read touch point information is, and the smaller the preset distance is, the more the read touch point information is.
Therefore, corresponding to the above-described case, when it is necessary to improve the generation efficiency of the colliding object, the amount of calculation can be reduced by setting a relatively large preset distance to acquire a relatively small number of pieces of touch point information. When the attractiveness of the collision object needs to be improved, the preset distance which is relatively small can be set to acquire the touch point information of a relatively large number, so that the smoothness of lines on the collision object is improved.
