Shown in Figure 3, be the flow chart of method one embodiment of two-dimensional game scene display provided by the invention, the present embodiment such as specifically can comprise:
Step 301, request instruction in response to displayed scene in described two-dimensional game, according to the initial position of existing object in described displayed scene, determine the target location of the described existing object that described request instruction is corresponding; Described existing object is the current object be in described displayed scene.
The present embodiment goes for the application scenarios that user uses two-dimensional network game application on the client, and now user interface interaction equipment can be the game server of network side.User is by after on client logs to game server, whether game server meeting Real-Time Monitoring user triggers the request instruction of displayed scene on the client, if, then subsequent game server responds the request instruction of described displayed scene, according to the target location of existing object corresponding to the initial position determination request instruction of existing object in displayed scene.And if user does not trigger the request instruction of displayed scene, then game server can not perform subsequent step.
In the present embodiment, what displayed scene represented is the image being shown to user by the window of client, includes Background and existing object in this image.Wherein, Background is the image of the corresponding position in the background base map of whole scene of game of displayed scene, and existing object is then the current object be in the position of displayed scene.This existing object can comprise the player characters who of user and various NPC; Background base map is then the Background of preset whole scene of game.
Be understandable that, the request instruction of displayed scene is by user's instruction triggered on the client, wherein can comprise the position of user-selected displayed scene in whole scene of game, the existing object indication information such as target location and target direction in displayed scene.Like this, when responding this request instruction, just can go to obtain displayed scene according to indication information.Certainly, also directly indication information can not be recorded in request instruction, but the mark that record one is corresponding, and go to search corresponding indication information in preset mark corresponding relation.
It should be noted that, in the present embodiment, in each displayed scene, the initial position of existing object can be the default location pre-set, and this default location can be the fixed position adopted in prior art.When determining the target location of existing object, need to determine according to its initial position.
Step 302, according to described target location, described existing object to be added in the Background of described displayed scene, and the direction of described existing object is adjusted to target direction corresponding to described request instruction, obtain described displayed scene; Described Background is the background base map that described displayed scene is corresponding.
It should be noted that, before adjustment, need the target direction first determining that existing object is corresponding in described request instruction.In general, target location and the target direction of existing object are all corresponding, when determining target location, just can determine target direction.Certainly, for the determination of target direction, can be first determine that target direction is determined by target location again in target location, also can be go to determine target location and target direction according to request instruction simultaneously.
Step 303, provide described displayed scene to user.
When providing to user, be on the client for the mode of user's display realizes by gained displayed scene.Wherein, client can show this displayed scene in the window of user interface.
In the present embodiment, by responding the request instruction of displayed scene, thus go to according to the initial position of existing object in displayed scene the target location determining corresponding requests instruction, thus can existing object be added in the target location of displayed scene with the target direction that request instruction is corresponding, thus make user can be obtained the displayed scene in different object's position and direction by the different request instructions assigning displayed scene according to oneself different demand, and then user can be made to obtain its easy to operate displayed scene, thus improve the convenient degree that user operates in two-dimensional game, for user brings better experience.
It should be noted that, in order to the quantity reducing the clicking operation that user will carry out when trigger request instruction improves Consumer's Experience further, can object erect-position relation in more preset displayed scenes, relativeness between the target location of existing object can be fixed in object erect-position relation, but can be different relativenesses between each object erect-position relation, such user only needs the object erect-position relation selecting its needs just can determine target location and the target direction of each existing object in displayed scene, and do not need to select respectively for each existing object again.
Shown in Figure 4, be the flow chart of another embodiment of method of two-dimensional game scene display provided by the invention.The present embodiment is on the embodiment basis shown in earlier figures 3, represents position with coordinate, and provides in step 301 a kind of concrete embodiment of the position that really sets the goal.The present embodiment such as specifically can comprise:
Step 401, request instruction in response to displayed scene in described two-dimensional game, obtain the coordinate of the initial position of described existing object in described displayed scene, as initial coordinate.
In the present embodiment, each position of existing object, displayed scene etc. can be represented with coordinate.Wherein, can be different coordinates for different positions in same scene, and also can be different coordinates in different scenes for same position.
In the present embodiment, what initial coordinate represented is the initial position that existing object is sitting in displayed scene, so this initial coordinate is the coordinate of existing object in displayed scene, its coordinate value calculates with the origin of coordinates of displayed scene.And the coordinate of displayed scene can be arranged on the summit in the upper left corner of displayed scene, and abscissa can forward to the right, ordinate can forward downward.
Step 402, according to described request instruction, determine the object erect-position relation of described displayed scene, and extract Coordinate Conversion rule corresponding to described object erect-position relation.
User, when triggering the request instruction of displayed scene, needs the object erect-position relation selected required for it, so can contain the indication information of object erect-position relation in this request instruction.Because object erect-position relation is a kind of default position relationship, so also corresponding Coordinate Conversion rule can be preset for each object erect-position relation, thus may be used for the coordinate calculating existing object target location wherein, i.e. coordinates of targets.This Coordinate Conversion rule is the corresponding relation between initial coordinate and the coordinates of targets of its correspondence.
Such as, can preset four kinds of object erect-position relations, wherein become symmetric relation between the position of same object in any two object erect-position relations, symmetry can be about the abscissa center line of displayed scene, ordinate center line or central point.As the schematic diagram of Fig. 5, be four kinds of object erect-position relations corresponding in a kind of displayed scene of fight.Wherein, displayed scene 1 and displayed scene 2 are symmetrical about abscissa center line, and displayed scene 1 and displayed scene 3 are symmetrical about ordinate center line, and displayed scene 1 and displayed scene 4 are about central point.
In the present embodiment, corresponding to above-mentioned four kinds of object erect-position relations, determined coordinate rule can be following the first rule, Second Rule, three sigma rule or the 4th rule:
Described first rule is: x 2=x 1, y 2=y 1;
Described Second Rule is: x 2=w-x 1, y 2=y 1;
Described three sigma rule is: x 2=x 1, y 2=h-y 1;
Described 4th rule is: x 2=w-x 1, y 2=h-y 1;
Wherein, described x 1for the abscissa in initial coordinate, described x 2for the abscissa in coordinates of targets, described y 1for the ordinate in initial coordinate, described y 2for the ordinate in coordinates of targets, described w is described displayed scene length on the horizontal scale, and described h is described displayed scene length on the vertical scale.Wherein, when displayed scene is the display window on screen, then w is the length of this window, and h is then the width of this window.
When determining corresponding rule from above-mentioned four kinds of Coordinate Conversion rules, determined Coordinate Conversion rule is all relevant with the object erect-position relation of target location with the object erect-position relation of initial position.Such as, in the example of aforesaid fight displayed scene, if it is displayed scene 1 that the object erect-position of initial position closes, when the object erect-position pass of target location is displayed scene 2, then determined rule is Second Rule, and when the object erect-position pass of target location is displayed scene 3, then determined rule is three sigma rule, when the object erect-position pass of target location is displayed scene 4, then determined rule is the 4th rule.Certainly, initial position can be preset fixed variable, so just only can determine Coordinate Conversion rule according to the object erect-position relation of target location.
It should be noted that, in the example of above-mentioned fight displayed scene, the position of original enemy NPC and player characters who is fixing, so original magic arts object is only drawn in original two fixing positions.And in the present embodiment, the existing object in fight displayed scene, through Coordinate Conversion, enemy NPC and player characters who can appear at four positions, and these four positions are symmetrical.In order to make magic arts object that enemy NPC and player characters who can be coordinated to show, magic arts object is drawn in the position that can adopt the mode of mirror image that magic arts object is not set in four positions.
Step 403, described Coordinate Conversion rule is utilized described initial coordinate to be converted to the coordinate of the target location of described existing object, as coordinates of targets.
During conversion, initial coordinate can be substituted in the equation group of determined Coordinate Conversion rule, the result calculated is coordinates of targets.
Step 404, according to described target location, described existing object to be added in the Background of described displayed scene, and the direction of described existing object is adjusted to target direction corresponding to described request instruction, obtain described displayed scene; Described Background is the background base map that described displayed scene is corresponding.
Obtaining coordinates of targets, existing object directly can added to the point of displayed scene on coordinates of targets.
It should be noted that, because the present embodiment carries out implementing on the basis providing optional object erect-position relation for user, so the target direction required when adjusting the direction of existing object also can by being preset at two-dimensional game and applying in the mode corresponding with object erect-position relation.Particularly, in the present embodiment, the direction of existing object is adjusted to target direction corresponding to target location can comprise: from the corresponding relation between preset object erect-position relation and object orientation, obtain the object orientation corresponding to object erect-position relation of described displayed scene, as target direction; The direction of described existing object is adjusted to described target direction.
Step 405, provide described displayed scene to user.
By the technical scheme of the present embodiment, by presetting object erect-position relation in some common displayed scenes, wherein, target location and the target direction of each existing object is included in object erect-position relation, like this, user is when assigning the request instruction of displayed scene, select once in the object erect-position relation that can only need preset at these, just can obtain its required displayed scene, thus avoid user repeatedly clicking operation just can complete the user operation inconvenience that position and the direction of existing object each in whole displayed scene are selected and caused, and the problem of frequent reciprocal effect systematic function between interactive device.
When user asks displayed scene, first need the Background and the existing object wherein that obtain displayed scene.Can go the situation of checking diverse location in whole scene of game at any time to make user, the request instruction that can respond user goes the displayed scene obtaining diverse location in scene of game to be supplied to user.
Shown in Figure 6, be the flow chart of the another embodiment of method of two-dimensional game scene display provided by the invention, the present embodiment such as specifically can comprise:
Step 601, in response to described request instruction, obtain the existing object in the Background of described displayed scene corresponding to described request instruction and described displayed scene, and determine the initial position of described existing object in described displayed scene.
In game application, shown by displayed scene is all certain part in whole scene of game, and in whole scene of game, on the diverse location of each object meeting real-time update in its background base map.Therefore, when obtaining displayed scene, need real-time response request instruction, and remove the Background determining to be positioned at its position range in scene of game and existing object according to the position range of displayed scene.
In the present embodiment, Background and existing object can be determined by the locative mode of coordinate.Such as, see Fig. 7, show in step 601 embodiment obtaining Background and existing object in displayed scene, wherein, can have different coordinate systems under different scene, the origin of coordinates of the coordinate system of each scene can be any point in scene, as the summit in the scene upper left corner.Present embodiment such as specifically can comprise:
Step 701, according to described request instruction, determine the coordinate of the calibration point of described displayed scene in described background base map, as demarcation coordinate.
Wherein, for demarcating the position of displayed scene in scene of game, a calibration point is provided to be displayed scene.This calibration point can be the point in displayed scene, the central point of such as displayed scene or top left corner apex.The coordinate of this calibration point in background base map, also i.e. its coordinate in whole scene of game.
Step 702, according to described demarcation coordinate, corresponding for the indication range of the described displayed scene coordinate range in background base map is defined as the displaing coordinate scope of described displayed scene.
When determining displaing coordinate scope, need to determine according to demarcation coordinate.Particularly, calculate by demarcating coordinate, displayed scene length on the horizontal scale and length on the vertical scale.
Such as, when calibration point is the central point of displayed scene, suppose that demarcating coordinate is (x 3, y 3), displayed scene is respectively w, h in length that is horizontal, ordinate, and (x, y) represents that the point being arranged in displayed scene is at the coordinate of background base map, then the displaing coordinate scope of displayed scene can be expressed as:
