The control method not only wholly controls the action of the non-player character, but also easily operates, simplifies fussy operating steps.
Description
Technical field
The present invention relates to a kind of control method of computer program, relate in particular to a kind of control method of non-player role.
Background technology
Non-player role (None Player Character is hereinafter to be referred as NPC) refers in particular in video-game or the online game and the friend side in the same camp of player role.Player role refers to the dominant role of player's control in video-game or the online game.
Under the prior art, NPC control has dual mode:
One, AI controls automatically:
AI controls down automatically, and the action of NPC is fully by AI (artificial intelligence, ArtificialIntelligence is hereinafter to be referred as AI) control, and the user can't control maybe and can only simply control (attacking, defend, follow, stop multiple AI state such as switching).
Advantage: under this control mode, do not need the user that extra operation is arranged, as long as the control player role.
Shortcoming: control not freely, NPC can make the behavior that some users do not expect.
Existing recreation is given an example: the human skeleton of wizard's calling in " the legend world ".
Two, the user manually controls:
The user manually controls, and by AI control, the user can't control fully in the action of NPC.
Advantage: under this control mode, the action of the major part of NPC is controlled by the user, can not make the behavior that some users do not expect.
Shortcoming: operate loaded down with trivial details because need a plurality of roles of control, so user's operation meeting is very loaded down with trivial details.
Existing recreation is given an example: the nihility passerby of wizard's calling in " World of Warcraft ".
Summary of the invention
The technical problem to be solved in the present invention provides a kind of control method of non-player role, both can fully control the behavior of NPC, can control easily again, has simplified loaded down with trivial details operating procedure.
For solving the problems of the technologies described above, the control method of a kind of non-player role of the present invention adopts the shadow mode to control non-player role, comprises the steps: the data structure of (1) foundation preservation shadow information; (2) add shadow information; (3) shadow moves: the motion track of storing each shadow, and judge track that following a period of time of shadow moves whether be on it shadow at the motion track of this section in the time, if, then after moving, the track of previous shadow or player role body is updated to a back shadow through fixed range; (4) shadow is attacked, attacked and is disappeared.
Described shadow information comprises identifier, position, direction and the animate of shadow.
Step (1) also is included in uses special array to deposit shadow information in the info class of player role.
Step (2) is specific as follows: adopting the mode of client-requested, server response, when player role obtains interpolation shadow stage property or receive server interpolation shadow message, is that this player role adds shadow information.
The motion track of the shadow described in the step (3) is that shadow or player role body track add a fixed range value on it, calculate displacement according to mobile start position and institute's elapsed time, the particular location of shadow obtains by key point position interpolation, described key point position comprises: the role begins when mobile, when the role changes speed, when the role changed direction, when role's displacement reached fixed range, the role stopped when mobile.
When the role moves to fixed range, not only need recorded key point position in the step (3), also will upgrade key point position information.
In the step (3),, obtain the distance that shadow current location: A. begins to have moved from key point according to Time Calculation by the following method in non-key occasion; B. search smaller or equal to the pairing node of the ultimate range of this distance in mobile key position information array according to this distance; C. according to the node that finds as the mobile computing starting point, next node carries out interpolation calculation as terminal point, the position that obtains is exactly the shadow current location.
Beneficial effect of the present invention is: adopt the inventive method, the player does not need to control moving of shadow (NPC), and shadow can be followed all the time at the player role rear; Therefore the player can control shadow and move to any its place that moves to of wanting, and shadow can not hinder the user and handle moving of its main player role, and shadow can not made the shift action that any player does not think that it is made yet.When the player attacks (push away ice or open ice), shadow can turn to the player current towards, and do attack (push away ice or open ice); Therefore the player can control shadow and attacks to any direction, and shadow can not hinder the user to be handled its main player role and attack, and shadow can not made any player and do not think that it makes attack.To sum up, the present invention both can fully control the behavior of NPC, can control easily again and did not have loaded down with trivial details operation.
Description of drawings
Fig. 1 is the schematic diagram that shadow moves in the inventive method;
Fig. 2 is the schematic diagram that shadow is attacked in the inventive method.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in more detail.
With " pushing away chivalrous " recreation be example, and in " pushing away chivalrous ", NPC is that the appearance forrns with shadow shows, and shadow is being followed player role all the time, and as the another one role, shadow can help player role to attack (promotion ice cube or open ice).
The control method of a kind of non-player role of the present invention comprises following concrete steps:
One, sets up a data structure of preserving shadow information
1, preserve the data structure SHADOWPLAYER of shadow information, the information of shadow comprises the identifier of shadow, position, direction and animate etc.;
2, in the info class of player role, use special array to deposit shadow information.
Two, add shadow information
Identical with the player role ontology information, the information of shadow also need all be carried out record the server and client side, so the generation of shadow is still adopted client-requested, the mode of server response.When the role obtains interpolation shadow stage property or receive server interpolation shadow message, call the AddShadowPlayer function and add shadow information for this role.
Three, shadow moves (shadow is followed)
The player does not need to control moving of shadow, and shadow can be followed all the time at the player role rear; Therefore the player can control shadow (NPC) and move to any its place that moves to of wanting, and shadow can not hinder the user and handle moving of its main player role, and shadow can not made the shift action that any player does not think that it is made yet.As shown in Figure 1, as gluttonous snake, the player does not need to control moving of shadow, and shadow can followed the player all the time, the virtual center point of shadow can be all the time at the point at the preceding 40pix place of player's virtual center point.
It is Core Feature during the shadow function realizes that shadow is followed.Shadow can followed the player all the time, the location track of shadow should be that shadow (or player role body) track adds a fixed range value on it, can overlap with the position of last shadow (or player role body) before this section is mobile after the distance moving fixedly guaranteeing, thereby reach the requirement of following.
In order to reach the requirement that shadow is followed, can be by keeping the motion track of each shadow, search the track position that satisfies fixed range before it then and reach the planning designing requirement.But this mode need expend very big data space, and the search operation meeting of mass data reduces program efficiency, therefore needs to consider to be optimized on this basis.
Consider that shadow will overlap with the position of a last shadow through fixed range, thus the track that moves of following a period of time of shadow a shadow is at the motion track of this section in the time on it just, so the motion track major part of shadow is identical.According to this judgement, then to consider after moving, the track of previous shadow (or body) to be updated to a back shadow through fixed range, a back shadow moves according to the track of previous shadow.Just do not need to keep whole motion tracks with this scheme, and only keep the track position of certain distance, compare a scheme and just saved with regard to memory space and improved search efficiency.
But even so, consider present recreation to play up action more frequent, if it is still bigger than normal to keep the position data output of role when playing up and shadow thereof at every turn.Because the role carries out linear uniform motion in recreation at present, move distance and time retention wire sexual intercourse then can calculate its displacement according to mobile start position and institute's elapsed time.Therefore, only need to keep several Key Points (be exactly the position of role's mobile status when changing, with this position as mobile starting point, change speed as the role, when the role changes direction) the position, inquire about these key point positions, the particular location of shadow can obtain by these key point position interpolation.
At present generally at following occasion recorded key point:
● the role begins when mobile;
● when the role changes speed;
● when the role changes direction;
● role's displacement (not being displacement) is when reaching fixed range;
● the role stops when mobile.
When the occasion of needs records (during full 40 pixels, the role begins to move, and the role changes speed, and the role changes direction, role stop to move etc.) upgrades in the key point position.For example, when the role moves to fixed range, not only need recorded key point position, also will upgrade key point position information.
In non-key occasion, obtain the shadow current location by the following method:
A. the distance that begins to have moved from key point according to Time Calculation;
B. search smaller or equal to the pairing node of the ultimate range of this distance in mobile key position information array according to this distance;
C. according to the node that finds as the mobile computing starting point, next node carries out interpolation calculation as terminal point, the position that obtains is exactly the current position of shadow.
Four, the attack of shadow
When the player attacks (push away ice or open ice), shadow can turn to the player current towards, and do attack (push away ice or open ice); Therefore the player can control shadow (NPC) and attacks to any direction, and shadow can not hinder the user to be handled its main player role and attack, and shadow can not made any player and do not think that it makes attack.As shown in Figure 2, when the player by pushing away ice or when opening ice, shadow can turn to the player current towards, and do the action that pushes away ice or open ice; When the player turns to an ice cube and position own is stopped by ice cube and when not having displacement, shadow also can turn to the player current towards; Shadow is regarded as player role during the judgement behavior, and shadow also has the role to belong to the notion of lattice decision metric, judges that shadow attack loca method is identical with player's decision method.
When shadow pushes away the brick attack, all push away brick at each shadow and attack decision operation, its decision operation is identical with the judgment mode of player role body, and concrete grammar is as follows:
At first, whether exist according to two lattice before the present cell positive direction of living in of shadow to push away object, distinguish the attack mode: can not push away object if do not exist in the last lattice of cell positive direction, then carry out the sky push operation; If can push away object if the interior existence of the last lattice of cell positive direction can push away not exist in object and preceding second lattice of cell positive direction, then carry out push operation; If can push away object if the interior existence of the last lattice of cell positive direction can push away also to exist in object and preceding second lattice of cell positive direction, then break operation;
Then, the identification information of record shadow, the operation information that is carried out and can push away object information sends shadow to server and attacks request;
Then, server judges that according to solicited message if think that this attack is legal, the instruction of then loopback success attack is carried out playing up of shadow attack in client, and its mode is identical with the player role body, so repeat no more.
Five, shadow is attacked and is disappeared
When shadow is attacked, shadow itself and its next stage shadow all will disappear.The implementation procedure that the processing procedure that shadow disappears and role's body disappear is basic identical, judges whether shadow is pushed, and the deletion shadow mainly illustrates the processing mode that shadow itself and its next stage shadow disappear here:
At first, confirm the to be killed identifier of shadow;
Then, according to this identifier (ID), in role's shadow, search corresponding sequence number;
Then, remove on the later shadow infologic of this sequence number, play shadow in the performance and attacked the back action that disappears.
