Description

Game character expression generation device and method, and storage medium

Technical Field

The invention relates to the field of computers, in particular to a device, a method and a device for generating game role expressions and a storage medium.

Background

With the development of science and technology, the animated characters in movies have become more vivid and lifelike, and the following two ways are generally adopted for the expression design of characters in movie animation in the related art:

the first method is as follows: picking up customized expressions one by one through a Morpher modifier, and then finishing expression animation through deformation;

the method needs to copy a plurality of expressions, and the pulling and pointing of the surfaces one by one can depict each expression in place, so that the understanding of a producer on the expression and movement is very tested, and the situation is not true. Since many faces are used and vertex information is read, the load on the engine is particularly large, which makes it difficult to create the expression of the character in the game in this manner.

And secondly, building a skeleton system, distributing weight information through Skin, and making skeleton animation, so that corresponding expression animation is provided.

The method can be simple and complicated, namely, only a few bones are built in the eyes and the mouth, and the eyes and the mouth can be opened by blinking and opening the mouth, but the expression is very stiff. The complexity is to establish corresponding skeleton points at each part of the face needing to move so as to simulate expression muscles. The more bones, the richer the expression and the more difficult it is to control, and animation needs to be made for each bone. In order to increase the number of character expressive bones with abundant expressions to hundreds, the animator has low working efficiency and is not easy to modify. In the prior art, a set of control aiming at an expression bone system is provided, a plurality of controllers are added to each bone by using position constraint, direction constraint and gaze constraint, but a complex expression muscle system is difficult to simulate, the manufacturing steps are very complicated, the workload is large, the efficiency is low, the time of day is spent just binding the facial expression of a character, if the complex points need more time, the limitation is more, the effect is not good, and finally the expression is not vivid enough, so that the game character expression is difficult to be manufactured in a game by adopting the method.

In view of the above problems in the related art, no effective solution exists at present.

step S202, generating a facial expression skeleton system containing a first number of bones;

step S204, controlling the facial expression skeleton system to adapt to a game role model;

step S206, establishing the association among bones in a first number of bones;

step S208, triggering the correlated movement of the first number of skeletons to generate game role expressions corresponding to the game role models.

Through the steps S202 to S208, the game role expression is generated without making the game role expression through a large number of bones, only the first number of bones in the facial expression bone system are matched to the game role model, and the bones are associated, so that the game role expression can be generated, the terminal engine can load the game role expression, the making efficiency of the game role expression is improved, and the problem that the method for making animation expression adopted in movie animation in the related technology is difficult to apply to the game expression making is solved.

In an optional implementation manner of this embodiment, the controlling the facial expression skeleton system to adapt to the game character model in step S204 in this embodiment includes controlling the skeleton in the facial expression skeleton system to fit the face of the game character model, and may be implemented by:

step S204-11, selecting a second number of bones and a third number of bones from the first number of bones; the second number of skeletons is a basic skeleton for generating the expression of each game role, and the third number of skeletons is a skeleton for enriching the expression of the game role;

it should be noted that, in this embodiment, the second number of basic skeletons refers to skeletons that must be used in the process of creating the expression of each game character, and in this application, the second number is preferably 18, and based on this, in a specific application scenario, the basic skeletons may be: the 4 eyebrow bows are driven to move, the 2 eyelids are driven to move, the 2 eyes are driven to move, and the 10 mouths are driven to move. Of course, the second number may be other values, for example, when only the eye expression needs to be made, the mouth expression does not need, and the value of the second number may be 8, that is, 4 eyebrow bows are driven to move, 2 eyelids are driven to move, and 2 eyes are driven to move; in case of expressions requiring nose in addition to eye and mouth expressions, the second number is larger than 18. That is, the second quantity may be a value corresponding to an actual situation. And the third number of skeletons for enriching the expression of the game character means that after the expression of the basic game character is completed based on the second number of skeletons, the skeletons can be appropriately added for more enriching the expression of the game character, so that the expression of the game character can be more vividly presented, that is, the third number is an adjustable number. In addition, the number of facial bones of the game character preset in the present embodiment is preferably 43. Of course, the above description of the number of bones in the present application is only an example, and the number of bones may be adjusted according to actual conditions during actual operation.

And step S204-12, fitting the second number of bones and the third number of bones to the facial architecture of the game character model.

For the game character model, the game character model already comprises the facial architecture, so that for the situation that the bones of the facial expression bone system are adapted to the facial architecture of the game character model, for example, the first number of bones comprises 18 basic bones and 20 rich game character expression bones, the case face organ structure is only needed, and the corresponding bones are attached to the corresponding facial architecture.

Regarding the above step S204-11 and step S204-12, taking a human face as an example in a specific application scenario, fig. 3 is a schematic diagram of controlling a facial expression skeleton system to adapt to a human face framework according to an embodiment of the present invention, and as shown in fig. 3, selected bones are respectively added to the human face framework one by one.

In an optional implementation manner of this embodiment, the manner of creating the association between the bones in the first number of bones, which is involved in step S204 of this embodiment, may be specifically implemented by the following manner:

step S204-11, setting script controls corresponding to a second number of bones and a third number of bones respectively;

step S204-12, selecting a designated bone from the second number of bones and the third number of bones;

step S204-13, an association between a specified bone and the second and third numbers of bones is created according to the script controller.

Based on the above steps S204-11 to S204-13, the selected bones (the second number of bones and the third number of bones) can be associated with a designated bone, and the creation of the association is performed by the script controller without manual and little harmonic setting.

Based on step S204, step S206 in this embodiment may specifically include:

step S206-11, setting a control contact;

wherein, the control contact can be one or more, and the control contact can be arranged on the appointed bone.

Step S206-12, triggering the movement of a designated bone through the control contact to drive the correlated movement between the second number of bones and the third number of bones; wherein the associated movement means that the second number of bones and the third number of bones simulate real expression muscle movement;

and S206-13, generating the expression of the game character according to the associated motion.

For the above step S206, in a specific application scenario, the following may be performed: in the process of making the expression of the game character, after a plurality of skeletons are selected, one skeleton is selected from the skeletons, so that the skeleton is associated with other selected skeletons, the association refers to that the skeleton can be associated with the movement of the skeletons, and the associated movement simulates the movement law of real expression muscles, thereby generating the expression of the game character. It should be noted that the simulation of the movement law of the real expression muscle is controlled by the expression of the script controller in step S204, and based on this, the corresponding game character expression can be obtained only by touching the control contact.

Wherein, the motor law of the real expression muscles is like anger, the facial expressions ferocify during the anger, the muscles on the face all converge together, thus show the expression of anger we usually see, this needs a lot of skeletons to cooperate each other and accomplish. The corresponding expression can be generated by driving other skeletons to move according to the movement mode of the expression muscles through the skeleton, the emotion expressed by the expression can be clearly known through the control of the script controller, and the film animation production load is lower compared with that in the related technology under the condition of meeting the user experience.

In order to make the production of the expression of the game character in the present application more convenient and faster, the method of this embodiment may further include:

step S208, after the game role expressions are generated, the expressions corresponding to each facial organ of the game role model are separated from the generated game role expressions; wherein, a game role expression includes: an expression of one or more facial organs;

step S210, selecting expressions of a plurality of facial organs from the split expressions of the facial organs for storage;

step S212, setting a plurality of first controls; wherein the saved tables of the plurality of facial organs are invoked through a plurality of first controls.

Through the steps S208 to S212, the locally stored expressions of a plurality of commonly used facial organs can be called by setting the plurality of first controls, so that the game expression characters can be directly used when being made next time, the making is not needed, and the making of the game expression characters is facilitated.

In another optional implementation manner of this embodiment, the method of this embodiment may further include: after the associated motions of the first number of bones are triggered to generate the expression of the game role, setting a second control; controlling the skeleton in the expression of the game role by calling the second control;

it should be noted that the operation of the control at least includes: hiding operation, displaying operation, selecting operation. Other operations are of course possible, such as delete, add, etc. The skeleton can be conveniently and rapidly operated through the second control, so that the expression of the game role is more efficiently made.

It should be noted that the first control and the second control referred to in this embodiment may be disposed on an interface of the terminal, where the interface interacts with a user.

The present application will be described in detail with reference to specific embodiments of the present example;

the specific implementation mode provides a method for generating the character expression of a hand game, which comprises the following steps:

step S302, an expression skeletal muscle system is created and associated control is realized.

Wherein a default expressive bone system is generated, as shown in fig. 4 a-4 b, fig. 4a is a schematic front view of the bone system, and fig. 4b is a schematic back view of the bone system; it should be noted that the number of bones is 43 at most. Can reduce the number of the plants to 18 at least. The 18 bones are core bones which cannot be deleted, and the rest bones can be optimized according to projects and requirements.

It should be noted that the 43 bones are the optimal number of bones in the embodiment, because in the hand game, the expression is not used, and mainly a character cannot have too many bones, so the number of bones with the optimal expression is 43 from the viewpoint of the performance and effect of the game, and then the number of bones can be reduced, and the number of bones with the minimum number of expression bones of a character can be only 18 bones, and by the above number of bones, the game can have a good expression animation effect, and the 18 bones are the necessary bones (4 eyebrow bows, 2 eyelid, 2 eyes, 10 mouth, and 18 in total) which form the most basic of the expression animation, so that the 43 bones can better simulate the movement of expression muscles, and can obtain a more real expression animation with better effect.

It should be noted that the skeleton system can be adapted to any face type, only the position of half face needs to be adjusted, and the other half is controlled by automatic mirror image, so that the operation is simple and convenient.

Step S304, an association of bones is created, and then expression muscle movements of the real character are simulated. Finally, a reduced control touch point is created for controlling the skeleton, as shown in fig. 5a to 5c, wherein fig. 5a to 5c respectively show different game character expressions.

The association refers to the association between bones, because each bone is independent, multiple bones can be associated by moving one bone after the association, and the movement law of the expressive muscles is simulated, for example, when qi is produced, ferocious facial expression occurs, muscles on the face can be gathered together, and therefore the facial expressive muscles can regularly move. Therefore, only one bone is moved to drive other bones to move according to the motion mode of the expression muscles, and the effect is very ideal.

Step S306, calling the saved expression pos through a tool setting button (corresponding to a first control);

wherein 5 expression tips, 5 mouth type tips are recorded and used as shown in fig. 6 a; as shown in FIG. 6b, when you click the tool button for recording the pos, the button will display the corresponding digital information, corresponding to the button for using the pos below, and record the pos first, then the pos can be used, which is very convenient.

In step S308, other commonly used tool buttons (corresponding to the second control) are set.

Wherein, can make skeleton show or hide, or other operations through this instrument button, and then make the efficiency of making promote again.
