According to the game opposite-game-level combination generation method in the example embodiment of the disclosure, on one hand, by using a time control mechanism, a game opposite-game-level combination which is most matched with the situation of a user is generated based on a game time length parameter, so that the user can experience more different game levels in personalized game time length, meanwhile, the time pressure and management burden of the user are reduced, the problem that the user cannot make selection in a limited time due to difficult selection can be solved, and the game experience efficiency and the user retention rate of the game of the user are improved; on the other hand, through enriching the game level combinations, the game playability and the interest are enhanced, the time, the difficulty and the play type of the game level combinations are controllable, and the problem that the generated random game level combinations cannot control the difficulty and the game compactness when the clearance duration, the difficulty and the like among different game levels are too large is solved, so that the game experience of a user is further improved.

Next, the above steps of the present exemplary embodiment will be described in more detail with reference to fig. 3 to 5.

In step S210, a standard clearance duration corresponding to a game level in a game level pool in a game is determined based on historical clearance data of a preset number of game levels in the game.

Wherein the game level pool is a collection of game levels provided in the game. A game level is understood to be a component of the game world, which is typically targeted for demarcation, and is an imaging of game rules and game content, as well as a carrier of game content and playability. A game level will typically have a predetermined goal, and then the process of overcoming the barrier to level setting by using the skills provided by the game to achieve this goal is the process of the player experiencing the level. The most basic composition of the game level is a game scene, and meanwhile, the game scene is also the simplest obstacle in the game level, and the scene size and the complexity determine the difficulty and the speed of a player to finish the game level.

The game has a plurality of game levels with great game level difficulty and game level duration difference, and the standard game level duration corresponding to each game level can be determined by collecting the historical game level data of the game levels, and the standard game level duration can be used for measuring the game level conditions of most users aiming at the game levels.

In this example embodiment, the historical clearance data of each game level in the game, or the historical clearance data of a part of the game levels may be obtained from a database for storing game data, for example, the historical clearance data of all users including clearance time, clearance times, and the like may be obtained from a UGC map database.

In this example embodiment, as shown in fig. 3, based on the historical clearance data of a preset number of game levels in the game, determining the standard clearance duration corresponding to the game level in the game level pool in the game may specifically include the following steps:

step S310, obtaining the clearance reference time length corresponding to the game level in the game level pool based on the history clearance data of the preset number of game levels in the game.

Through statistics and analysis of historical clearance data of all users, statistical parameters such as median, average number and the like of historical clearance duration can be obtained, and the parameters can be used as clearance reference duration corresponding to a game level. The median of the history clearance duration is that all the history clearance durations are arranged from small to large, the value of the middle position is taken as the median, and the index for reflecting the data middle value is used. The average of the historical clearance duration is an average value calculated through all the historical clearance durations, and can reflect the rough condition of the historical clearance of the user. In addition to the median and the average, other statistical parameters may be used as the clearance reference duration corresponding to the game level, which is not particularly limited in this exemplary embodiment.

S320, adjusting the clearance reference time length corresponding to the game level according to the time length adjustment parameter, and determining that the clearance reference time length corresponding to the adjusted game level is the standard clearance time length corresponding to the game level.

Wherein the duration adjustment parameter includes at least one of: the game level information processing system comprises a first time length adjustment parameter and a second time length adjustment parameter, wherein the first time length adjustment parameter is configured to be a fixed adjustment parameter, and the second time length adjustment parameter is configured to be an adjustment parameter determined according to the level information of the game level, and is a flexible adjustment parameter.

In this example embodiment, the clearance reference duration corresponding to the game level may be adjusted according to the first time adjustment parameter, and the adjusted clearance reference duration corresponding to the game level is determined to be the standard clearance duration corresponding to the game level. The standard clearance time length can be determined according to the clearance reference time length and the first time length adjustment parameter, for example, twice the standard deviation of the historical clearance time length can be added on the basis of the median of the clearance time length, so that the moderate game difficulty is ensured, but the method is simple or complex.

In this example embodiment, the clearance reference duration corresponding to the game level may be adjusted according to the second duration adjustment parameter, and the adjusted clearance reference duration corresponding to the game level may be determined to be the standard clearance duration corresponding to the game level. The method comprises the steps of obtaining the gate information of the game gate, and adjusting the standard gate duration corresponding to the game gate according to the gate information, wherein the gate information comprises the gate type, the gate difficulty and the number of single-game players.

In this example embodiment, the clearance reference time length corresponding to the game level may be adjusted according to the first time length adjustment parameter, so as to obtain a first clearance reference time length corresponding to the game level, and then the first clearance reference time length corresponding to the game level is adjusted according to the second time length adjustment parameter, so as to determine that the adjusted first clearance reference time length corresponding to the game level is the standard clearance time length corresponding to the game level. And the standard clearance time length is adjusted twice based on the first time length adjusting parameter and the second time length adjusting parameter, so that the standard clearance time length can be more accurate.

When the clearance reference time length corresponding to the game level is adjusted according to the second time length adjustment parameter, adjustment can be performed according to information such as level difficulty, number of players in a single game, and the like, for example, if the level difficulty of the game level is greater than the reference level difficulty, the time length upward adjustment parameter is determined according to the level difficulty of the game level, and the clearance reference time length corresponding to the game level is adjusted according to the time length upward adjustment parameter; if the level difficulty of the game level is smaller than the reference level difficulty, determining a time length downward adjustment parameter according to the level difficulty of the game level, and adjusting the clearance reference time length corresponding to the game level according to the time length downward adjustment parameter.

For another example, if the number of single-game players of the game level is greater than the number of single-game reference players, determining a time length upward adjustment parameter according to the number of single-game players of the game level, and adjusting the clearance reference time length corresponding to the game level according to the time length upward adjustment parameter; if the number of single-game players of the game level is smaller than the number of single-game reference players, determining a time length downward adjustment parameter according to the number of single-game players of the game level, and adjusting the clearance reference time length corresponding to the game level according to the time length downward adjustment parameter.

Different levels can be classified into different levels, such as adventure, competition, puzzle, etc., according to different map types and the number of users. The standard clearance time length is finely adjusted according to factors such as the type of the gate, the difficulty of the gate, the number of players in a single game and the like, so that the compact sense and the stimulation sense of the game can be ensured. For example, if the difficulty of a certain class of checkpoints is high, the standard clearance time can be prolonged appropriately to ensure that the user has enough time to explore the map; if the difficulty of a certain class of checkpoints is small, the standard clearance duration can be properly shortened to ensure that the game is not too simple. For another example, if the number of single games at a certain level is greater than N, the standard clearance duration may be extended appropriately to ensure that the users have enough time to cooperate to complete the game; if the number of single games at a certain level is less than N, the standard clearance time can be properly shortened to ensure the compact sense and the stimulation sense of the games.

In step S220, a game duration parameter is acquired.

In this example embodiment, the game duration parameter refers to a total duration parameter currently being played by the user. The step of obtaining the game duration parameter comprises at least one of the following:

responding to the game time length setting instruction, and determining a game time length parameter according to the time length parameter set in the game time length setting instruction; and determining a game duration parameter according to the historical game information of the current account.

In this example embodiment, a setting interface of the game duration may be provided for the user on the graphical user interface of the game terminal, so that the user may set an appropriate game duration parameter according to the time of the user. The game duration parameter may also be determined according to historical game information of the current account, where the historical game information may include a level type proportion, a level difficulty proportion, historical game information, and the like, which are historically selected by the user.

In step S230, a plurality of target game levels are selected from the game level pool according to the standard clearance duration corresponding to the game level in the game level pool.

The difference value between the sum of the standard clearance time lengths corresponding to the target game level and the game time length corresponding to the game time length parameter is smaller than or equal to the time length error threshold value.

In this example embodiment, the candidate game level may be obtained by obtaining level screening information, and screening the game level in the game level pool according to the level screening information, and then selecting a plurality of target game levels from the candidate game levels according to the standard clearance duration corresponding to the candidate game level.

The step of acquiring the checkpoint screening information comprises at least one of the following steps:

responding to the checkpoint information screening instruction, and determining checkpoint screening information according to the checkpoint information screening instruction; and determining the level screening information according to the historical game information of the current account.

In this example embodiment, a selection interface of level information such as level type and number of rooms may be provided for the user on the graphical user interface of the game terminal, so that the user may select a suitable game mode according to his own preference.

After the level screening information input by the user is acquired, candidate game levels meeting the conditions are screened from all game levels according to the level screening information selected by the user, and players select high game difficulty or multiple participants and then provide more game levels with longer standard duration. When screening candidate game levels, the game level information such as the popularity value of the game level can be combined for screening, and the popularity value of the game level can be determined according to the historical user scoring the level, playing records and other data.

In this example embodiment, the candidate game stages may be arranged according to the standard clearance duration corresponding to the candidate game stages, and the target game stages are sequentially selected from the arranged candidate game stages according to the standard clearance duration from small to large until the difference between the sum of the standard clearance durations corresponding to the plurality of target game stages and the game duration corresponding to the game duration parameter is less than or equal to the duration error threshold.

In this example embodiment, the search is performed based on the game duration input by the user and the standard clearance duration corresponding to each candidate game level, so as to finally obtain a game level combination with the accumulated clearance duration Σ (xi) approximately equal to the game duration parameter X, where xi is the standard clearance duration of the game level meeting the condition.

And selecting the game level with the shortest standard clearance time from the candidate game levels by using a random algorithm, and sequentially adding the game levels into the game combination until the accumulated clearance time is close to or equal to the game time input by the user, so that the game level in the combination is the largest, and the user experiences more random levels as much as possible.

In step S240, the plurality of target game stages generate a current game pair stage combination.

In this example embodiment, the target game levels may be arranged according to a preset clearance duration arrangement sequence, and the current game pair level combination may be generated according to the arranged target game levels. For example, the target game stages can be arranged in the order of the standard clearance time length short and long, so as to ensure the game interest. And finally, recommending game levels to the user in sequence based on the current game pair level combination, so that the user plays the game according to the level sequence in the current game pair level combination.

In step S250, a game outcome of the current game outcome is obtained, and a game outcome corresponding to the next game outcome is determined according to the combination of the current game outcome and the game outcome.

The game pair level is a game level for playing a game according to the game pair level combination, and the current game pair level is a game pair level in the current game pair level combination.

In this example embodiment, when the user plays a game based on the recommendation of the game play level combination, a game play level corresponding to the next game play may be determined according to the current game play level play result returned in real time.

The outcome of a game against a game at the present time may refer to the winner or winner of the game, depending on the type of the game, the method can also refer to the actual clearance time of the user, and can also comprise the current scoring data of the current game clearance card and other clearance information. If the game result of the current game is negative, ending the game; if the outcome of the current game against the game is a winner, the game pair level corresponding to the next game pair is determined directly according to the game pair level combination. In this example embodiment, as shown in fig. 4, determining a game pair level corresponding to a next game pair according to a current game pair result and a game pair level combination may specifically include the following steps:

step S410, current scoring data of the current game check-in and historical scoring data of the current game check-in are obtained.

After the user completes a relationship, the current game is scored on the game gate, and the user scoring data of the current game gate is compared with the historical scoring data.

The difference between the current scoring data and the historical scoring data may be calculated using the following formula: difference = current score-historical score. The historical score may be calculated using the following formula: historical average score = Σ (xi)/n, where xi is the score for all users of the game level and n is the number of scores.

And S420, if the current scoring data is greater than the historical scoring data, acquiring the standard clearance duration corresponding to the next prepared game check point of the current game check point in the current game check point combination.

If the current scoring data is greater than the historical scoring data, the user is indicated to like the game level, and the subsequent level can be determined according to the level type of the current game level.

S430, selecting a game level with the same level type as the current game pair level and the same standard clearance time length as the next prepared game pair level from the game level pool as the game pair level corresponding to the next game pair.

And selecting one game level which has the same duration with the next prepared game level and has the same type with the current game level from the game level pool as the game level corresponding to the next game level, so that the user can play more game levels of the same type.

In this example embodiment, as shown in fig. 5, determining a game pair level corresponding to a next game pair according to a current game pair result and a game pair level combination may further include the following steps:

S510, obtaining the actual clearance time of the current game opposite-office level according to the current game opposite-office result, and obtaining the same kind of game opposite-office level with the same type as the current game opposite-office level in the current game opposite-office level combination.

After the user completes one pass, the subsequent pass can be adjusted based on the actual pass time of the user, and the standard pass time of the current game on the pass is compared with the actual pass time of the current game pass user.

S520, if the actual clearance time is smaller than the standard clearance time of the current game pair, selecting a game pair which has the same standard clearance time and higher level difficulty from a game pair pool as a replacement game pair according to the standard clearance time of each similar game pair.

When the actual clearance time of the user is smaller than the standard clearance time, the user can be considered to be better than the game level of the type, so that the game level which is more difficult to replace later can be ensured to feel the stimulus of the user.

S530, if the actual clearance time is longer than the standard clearance time of the current game to the game gate, selecting the game gate with the same standard clearance time and lower level difficulty from the game gate pool as the alternative game gate according to the standard clearance time of each similar game to the game gate.

When the actual clearance time of the user is longer than the standard clearance time, the user can be considered to be less good for the game level of the type or the current game level is higher, so that the level of the follow-up game level can be reduced. And prompts can be added in the follow-up checkpoints, so that the game difficulty is reduced.

S540, replacing the same kind of game pair level in the current game pair level combination with a corresponding replacement game pair level, and determining a game pair level corresponding to the next game pair according to the replaced game pair level combination.

After the difficulty of the subsequent similar game level is adjusted, the game level corresponding to the next game level is determined according to the replaced game level combination, so that the game experience of the user is ensured.
