Examples
As shown in fig. 1, in a first aspect, an embodiment of the present application provides an action game anti-plug-in method, which includes the following steps:
s1, sending a target operation instruction to a server through a client;
s2, synchronously transmitting a target operation instruction through a server according to a preset frame rate;
in some embodiments of the present application, the server sending the instruction means that the next computing module inside the server performs the computation, the computation is all on the server, and the plug-in cannot be modified on the client.
S3, calculating the result of each logic frame of the game according to the target operation instruction so as to obtain result information;
further, the game field per logical frame result is calculated according to the target operation instruction so as to obtain field result information.
Further, a game action judgment per logical frame result is calculated according to the target operation instruction to obtain action judgment result information.
In some embodiments of the present application, the logic frame calculation includes two aspects, namely, a view calculation and an action judgment calculation, and the game plug-in operation is comprehensively prevented from the two aspects.
Regarding the view calculation:
under the condition that the terrain view is not considered to be blocked, the player view distance is limited, the view angle FOV is generally smaller than 180 degrees, the player's role is taken as the origin of coordinates, the east-west direction is taken as the X axis, the north-south direction is taken as the Y axis, a coordinate system is established, since the coordinate axes are not rotated, the speeds of other player roles are equal to those of the player's role and are v, the upper limit of the movement speed on the coordinate axes is 2v, the rotation angle speed is not limited, the other roles conform to the random walk rule on the 2d plane, under the rotation condition, the player view is changed from the dotted line position to the solid line position as shown in fig. 2, and two area areas are formed at the moment that the player rotates the view because the rotation angle speed is not limited, A: no longer monitors the area, B: the monitoring area is newly added. The following conclusions are drawn: the newly added monitoring area presents the expectations E (B) of other people>>The areas are no longer monitored for the presence of other people's expectations E (a); appearance means that the new target appears and the new target is excluded from the field of view. And (3) proving: t0 is the time from the last spin field, at time t0, dt time has elapsed, reaching t1, the player turns to cause the A, B region, then there are: t1 time point A region has expectations of othersE (a) =t0 time a region presents the expected E (A1) of others-expected E (A2) of dt-time other people leaving from a region a) +expected E (A3) of dt-time other people entering a region a. the t1 time point B region has the expected E (B) =t0 time B region where the expected E (B1) of others appears-the expected E (B2) that the dt-time-elapsed others leave from the B region) +the expected E (B3) that the dt-time-elapsed others enter the B region. Obviously, there are: lim dt→0 E(A1)＝0，lim dt→0 E (A2) =0, and E (B1) is positively correlated with t0, so there is E (B)>>E(A)。
In practical situations, the optimal strategy of the searching opponent is reduced by t0 as far as possible, and when t0 is small enough, namely the visual field is rotated as far as possible, the visual field is intuitively equivalent to a circular visual field. It is foreseeable that the following measures are taken in engineering to prevent this: when the visual field rotates, a new monitoring area B is not obtained instantaneously, but a certain unfolding speed is needed; if the expansion speed is set to be the B region area S (B)/B region complete acquisition time T, S (B, T1) is set to be the newly added monitoring region obtained by dt time, lim can be obtained dt→0 S (B, t 1) =0; then setting a constant V (S) for the field of view expansion speed effectively limits the 360 degree full field of view that can be achieved by non-real operation.
In software engineering, it is impossible to approach dt to 0, a logical operation frame is set to 10-30 frames per second as appropriate according to the computing power of a computer, a newly added view acquisition speed is set to V (S) per frame time is set to t, the view FOV angle is unchanged to be a radian, S influences the current player view radius NowR, the player has the maximum view radius MaxR, and the view expansion area is acquired within 1 frame time. Then detecting the change degree of the vision field in each frame of movement of the player, and controlling the newly added vision field area to be not more than S by changing the vision field radius R, wherein in the frame, the rotation radian of the vision field is set as t, and the current vision field radius NowR is set as MS=NowR t NowR/2 if the current vision field radius NowR is not limited; if MS > =s, indicating that a restriction of newr is required to achieve the objective, then the new radius newrnext=min (MaxR, sqrt (2*S/t)); if MS < S, the explanation does not need to limit newr, the current field radius newrnext=min (MaxR, sqrt (2 x (S-MS)/a+newr x newr)) may be increased according to the difference.
Regarding the action judgment calculation:
in the action combat game, a period of time from the start of an attack action of a player to the attack judgment is called attack front shaking time t, and if no restriction relation exists, the advantage of front shaking is great, so that many games are designed with a cyclic restriction mechanism, such as permanent robbing of a inexperienced master, common attack of a master, vibration of a cutter and restriction of the master by the cutter. However, the imprecise action mechanism can cause the cheating player to achieve the effect of looking first and then through quick response and operation, for example, in some cases, in the case of ever robbing, part of common attacks can be cancelled through other actions such as jumping and converted into other actions, so that the effect of looking at the opponent body and then using a vibrating knife to remove the restriction is achieved, and the effect that who really goes first and who is restricted can be caused.
Then to solve such a problem, there are the following algorithm design element features:
after confirming the sign, the direction cannot be canceled or changed; after the opponent takes out, the corresponding check number is used again, so that the check effect cannot be achieved; after aiming and confirming the release attack action, the player cannot cancel, and after starting the attack action, the first attack judgment is generated after the time t; in the actual situation, the T value has a design upper limit MaxT, so the actions can be divided into a fast class with forward shaking time in the interval (0, maxT/2) and a slow class with forward shaking time in the interval (MaxT/2, maxT), the basic gram relationship is that the fast class is restricted by the slow class, the fast class is not operated, the slow class is not operated, so the ring comparison relationship is generated according to the action classification E, the opening and closing operation is not performed, in each classification E (O), the effect of the attack with the forward shaking time before the attack is restricted is also constructed, so the action caused by each attack instruction has a judging value N (T), the attack sent simultaneously is judged according to the N (T) to have a certain comparison relationship, in order to avoid the problem generated after the attack action, the attack starting time point s is provided, the N (T, s) is provided, when two time points s (0) s (T) are respectively, N (T) is not provided with the judging value N (T) of the attack starting time point S (T) 1), N (T) is not provided as the judging value N (T) is 0), and N (T) is not provided as the judging that before the attack time point (T) 1) is 0 (T) is 0) and S (T) is 0, respectively more than the attack time point (T) is 0, t is the time from the start of the attack to the current time point, the determination value changes with the increase of T, N (T, T) =t+t×c, where C is a constant much larger than MaxT, and then the determination of the restriction relation of action O at the determination time point Ts can be performed by N (T, T) value, T value, classification E, with > | < indicates that restriction is restricted, |=indicates that equalization.
O is an attack action, and when t (a) -t (b) > MaxT/2, O (a) | < O (b); otherwise, comparing N (T, T), if N (T, T) (a) < N (T, T) (b), there is O (a) | < O (b).
For classification of O, if E (O (a)) is a slow attack and E (O (n)) is not operational, then there is O (a) | < O (n); for classification of O, if E (O (a)) is a fast attack and E (O (n)) is not operational, then O (a) > |O (n).
In the actual action game engineering, a simpler method is adopted, according to the calculation power of a computer, a logic operation frame is set to be 10-30 frames per second, and each frame time is Ft, so that MaxT on action design is converted into a frame number MaxN=MaxT/Ft rounding, and the hand-out speed t is also rounded with a hand-out frame number n=t/Ft; also, n is less than or equal to MaxN/2, which is a fast attack, and n is greater than or equal to a slow attack, and is classified as E. When the action release is set, the player character has a variable value N which grows every frame, the starting value is N, and the growth value of every frame is C, wherein C is larger than MaxN; when the attack action starts the 0 th frame, n=n, in each frame, N increases from C, through N frames to the N th frame, an attack decision is generated, and the decision has a fixed value P, p=n×c+n. The P (a) of the releaser a and the N (B) of the determined party B are now compared and the classifications E (a) and E (B) are considered. E (B) is not operated: if E (A) is a slow attack, judging that the attack fails, and obtaining advantages by an opponent B; if E (A) is a fast attack, then the decision is successful, and A takes advantage. E (B) is a certain type of attack action, and the front shaking frame number is n (B): when P (A) > N (B), judging success, and A obtains advantages; when P (a) < N (B), the decision fails, the a side obtains an uncontrollable state for a period of time, the continuous frame number is MaxN/2, and returns to the inoperative state after the end, and when P (a) =n (B), the equilibrium is determined. Examples: setting maxn=2 seconds, ft=0.1 per second, then MaxN is 20, n for each action O is in the range of [1,20], and the following table of restriction relations is presented in table 1:
table 1:
s4, obtaining and filtering the result information according to the client flag information, and distributing the filtered result information to the corresponding client.
Further, acquiring and determining information to be received of each client according to the mark information of each client; and filtering the result information according to the information to be received of each client so as to obtain and send the target information to the corresponding client.
In some embodiments of the application, the server calculates the result information that it has calculated that the player user's visual field can see the opponent's location, and that opponent's location that is not in the visual field is not issued to the client. So as long as the server is not breached, even if a similar perspective is opened, an adversary outside the specified field of view will not be seen. This view determination is the above filtering, i.e. if a certain opponent is not seen in the player's view, no information of the certain opponent will be sent to the player's client, and if the player wants to obtain a 360-degree view through extremely fast rotation by operating the plug-in, under the view algorithm, the view radius will be rapidly reduced when the view is rotated fast due to a certain expansion speed, the view capability is almost lost, and the view radius can be expanded only when the player stops or rotates slowly. This radius of view is calculated by a calculation module.
Under the action determination computing mechanism of the server, the player is not valid even if the instant operation class plug-in is turned on. For example, the non-cheating player carries out a fast attack action, the cheating player carries out fast recognition and operation through plug-in, carries out slow attack to check immediately before the next 1 frame operation, the reaction time reaches below 0.1 seconds, and exceeds the reaction speed of normal human beings, but the check effect cannot be achieved, since the non-cheating player releases 1 frame earlier than the cheating player, when the attack judgment is generated in the N1 th frame, the judgment value N (not) =n1+C N1 of the non-cheating player is N (work) =n2+C (N1-1), and even if C is greater than the maximum value MaxN of all N, N2> N1 is present because N2-N1< C, the non-cheating player still obtains the advantage of attack judgment.
It can be found that the opponent can be successfully restrained unless the cheating player expands the restraining action in the same frame or before, but the cheating player can know that the server has issued the instruction operation through the opponent when the opponent expands the action, and unless the server is broken or the time flows backwards, the server cannot be interfered to do the operation logic of the previous frame, so that the plug-in script of the limit response type is not effective.
For another example, a non-cheating player may launch a slow attack, a cheating player may launch a fast attack, and the cheating player may be restricted because the launched attack may not cancel the retrieval or change direction, and the server may consider the operation invalid and may not change the restricted result as long as the server is not breached.
In order to solve the technical problem of game plug-in the prior art, the application calculates and judges related instruction operation in the game, adjusts corresponding game operation according to the conditions of different clients and sends corresponding information to the clients so as to ensure the normal system of the game. Firstly, a client sends a specified operation instruction to a server, the server synchronizes the instruction under a certain frame rate and sends the instruction to a core algorithm module in the server, the core algorithm module calculates the result of each logic frame of a game, sends the result to information filtering and distribution, acquires and filters result information according to each client mark information, distributes the filtered result information to a corresponding client, and sends different information to each client according to each client mark filtering information.
The application only operates at the server side, and no additional anti-plug-in program is required to be installed by a user; the algorithm is simple, and the performance consumption is low; the anti-cheating effect is good, and even if a player opens the reaction speed accelerating type cheating device, the influence on the game win or lose is weak. The application can effectively avoid the influence of the ultra-high speed reaction and the operation capability on the game win or lose, and ensure the instant making and the expression of the game.
