Description
Technical field
The present invention relates to a kind of game object control field more particularly to animation displacement drawing process, device and game
Motion control method, the device of object.
Background technology
The mode of the athletic performance of common control object often has the following two kinds in game：
A kind of mode of control object athletic performance is：The fine arts make the skeleton cartoon in an original place, then programmed logic
In control object move, such as personage walking performance, the skeleton cartoon that an original place is walked, then program can be made with the fine arts
It allows personage to be moved by certain speed in code logic, reaches personage in the expression effect walked.This mode is suitable for object fortune
The more fixed situation of dynamic speed, for example walk, run just is not easy to use but if being the more complex situation in movement velocity, track
Programmed logic goes to realize.
The mode of another control object athletic performance is to use animation displacement.In this manner, the fine arts make
It is not an original place animation but a skeleton cartoon for carrying displacement, when then playing this animation in gaming, Jiu Huigen
Carry out mobile object according to the deformation trace of this animation, the advantages of this mode, which is the performance of object in gaming, to be set with the fine arts
Meter it is consistent, can have speed, the complicated variation on track, enhance the expressive force of game object.Therefore this mode is through common
In on the athletic movement of game object, for example (centre has certain speed rhythm to become for personage splits toward front jumping in game technical ability
Change), the movement of personage is showed in this way, will compare nature.But it in actually using animation displacement, is frequently encountered
A problem be that the fine arts, which have made one section of animation deformation trace, can move to some target point opposite with current location,
But planning wishes that the object eventually moves to another target point.Still by taking technical ability is split in the jump of personage as an example, what the fine arts may make
Deformation trace is to jump ahead at 3 meters, but the target of attack of personage is in practice in front at 5 meters, in this way if still according to
Deformation trace originally moves personage, can not just attack target.In this case, it is necessary to according to actual target point,
The deformation trace of animation is stretched, 5 meters are stretched to from 3 meters, here it is so-called animation displacement stretching techniques.Here
" stretching " is not limited to elongate, it is also possible to be situation about shortening, for example actual target point is closer from object.
The basic ideas of the animation drawing process of game engine on the market are to calculate actual target point and the fine arts at present
Displacement difference between the target point of the deformation trace of making obtains one then by this displacement difference divided by the run time of animation
This speed is added to object then during animation play, as a compensation speed, exists in this way by a speed
After animation play, corresponding object will be equal to that displacement difference there are one bit shift compensation, and it is last right to ensure that in this way
As specified target point can be displaced to.

For technical ability, if it is that stagnant sky is motionless that jump, which splits technical ability in intermediate personage for some time, we also are intended at this section
Between do not stretch, if jumped, personage's motion ratio when split end is very fast, and the speed that we also are intended to stretching this period can
Than very fast.If the movement produced in stagnant null process because of stretching, it is clear that this is exactly phenomenologically less to meet expection
's.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
It is a kind of flow diagram of animation displacement drawing process provided in an embodiment of the present invention referring to Fig. 1.The present embodiment
It is to be directed to carry out mobile object using animation displacement in gaming, when current animation needs the target point (realistic objective being moved to
Point) it is inconsistent with the target point of former animation deformation trace when, what when being stretched the case where, described, as shown in Figure 1, this hair
A kind of animation displacement drawing process that bright embodiment provides includes step：
S101, the displacement difference that current animation needs the target point being moved to and the target point of former animation deformation trace is calculated；
Wherein, Fig. 2 is the input example of a former animation deformation trace, it is shown that each frame in former animation deformation trace
The position for the game object that the moment fine arts make.It should be understood that the example of a plane is shown in Fig. 2, i.e. former animation position
The position of each frame moved in track is coordinate points P (i)=(X of two dimensional surfacei,Yi).But in other embodiments, former dynamic
The position for drawing each frame in deformation trace can also be coordinate points P (i)=(X of a three dimensionsi,Yi,Zi), not shadow
Ring the implementation result of the present invention.
For the former animation with N frames, the position (coordinate points) of nth frame is the target point (seat of former animation deformation trace
Punctuate).For example, in fig. 2, former animation includes 6 frames, then the position P (6) of the 6th frame is the target point of former animation deformation trace.
Assuming that the position of the last frame for the cartoon track that the fine arts make is P (N), but reality is wished object displacement to D
Locate (shown in such as Fig. 2), then there are a displacement difference (D-P (N)) (vectors) between them.Wherein, the displacement difference D-P
(N) it is that the target point of former animation deformation trace is directed toward the displacement for the target point that current animation needs are moved to.It should be understood that by
Needing the target point being moved in current animation, there may be remote or close (the opposite startings of the target point than former animation deformation trace
Point) two kinds of situations, therefore, the direction of displacement difference D-P (N) may be positive direction or negative direction (opposite starting point).
S102, the bit shift compensation for calculating each frame in former animation deformation trace, make the size of the bit shift compensation of each frame
It is proportional to shift length of the frame in former animation deformation trace, and makes the bit shift compensation of all frames in former animation deformation trace
It is added and is equal to the displacement difference；
Wherein, the method for specifically calculating bit shift compensation is as follows：
Assuming that the position of the last frame for the cartoon track that the fine arts make is P (N), but reality is wished object displacement to D
Locate (shown in such as Fig. 2), then there are a displacement difference D-P (N) between them, then we need in each frame according to this position
It is poor to move, and contraposition is moved and compensated.The mode of bit shift compensation is so that the size of the bit shift compensation of each frame is proportional to this frame and exists
Shift length (scalar) in former animation deformation trace, and make the bit shift compensation addition of all frames etc. in former animation deformation trace
In the displacement difference (direction of the bit shift compensation of all frames is consistent with the direction of the displacement difference).
Specifically, calculating the bit shift compensation of each frame in former animation deformation trace by following formula (1)~(2)：
M (i)=0, i=1 (1)
M (i)=(D-P (N)) * | P (i)-P (i-1) |/S, i >=2 (2)
Wherein, M (i) is the bit shift compensation of the i-th frame in former animation deformation trace, and P (i) is in former animation deformation trace
The position of i-th frame, P (N) are the target point of former animation deformation trace, and D is the target point that current animation needs are moved to, and S is original
The total displacement length (scalar) of animation deformation trace.
Wherein, (1)=0 M indicates that the start frame in former animation deformation trace need not carry out bit shift compensation, and follow-up
The bit shift compensation M (i) of each frame (for example, i-th frame) is proportional to the shift length from i-1 frames to i frames.In addition,
Wherein, current animation needs the displacement difference (D-P of the target point being moved to and the target point of former animation deformation trace
(N)) S101 is obtained through the above steps.
For the former animation with N frames (N >=2), calculating the specific method of the total displacement length of former animation deformation trace is：
S=| P (2)-P (1) |+| P (3)-P (2) |+...+| P (N)-P (N-1) |
Wherein, S is the total displacement length of former animation deformation trace, and P (i) is the position of the i-th frame in former animation deformation trace
It sets (coordinate points), P (N) is the position (coordinate points) of the last frame of former animation deformation trace, i.e., the mesh of former animation deformation trace
Punctuate.| P (i)-P (i-1) | for shift length of the i-th frame in former animation deformation trace in former animation deformation trace, i.e., i-th
Air line distance between the position of frame and the position of the (i-1)-th frame, wherein 1≤i≤N.
Therefore, the position (coordinate points) based on each frame given in former animation deformation trace, can calculate former animation
Shift length of each frame in former animation deformation trace in the total displacement length of deformation trace and former animation deformation trace,
To which the bit shift compensation of each frame in former animation deformation trace be calculated according to above-mentioned formula (1)~(2).For example, Fig. 3 is aobvious
The bit shift compensation based on each frame in the obtained former animation deformation traces of Fig. 2 is shown.
In addition, according to formula (1)~(2) it is found that since displacement difference (D-P (N)) is a vector, bit shift compensation M (i)
For a vector, and direction is identical as the direction of displacement difference (D-P (N)).
S103, the bit shift compensation for each frame being calculated, which is added to, corresponds to the displacement of frame in former animation deformation trace
On, to obtain current animation deformation trace.
Current animation deformation trace is calculated by following formula (3)~(6)：
V (i)=0, i=1 (3)
V (i)=P (i)-P (i-1)+M (i), i >=2 (4)
Q (i)=P (i), i=1 (5)
Q (i)=Q (i-1)+V (i), i >=2 (6)
Wherein, V (i) is that (namely the i-th frame is with respect to the position of the (i-1)-th frame for the displacement of the i-th frame in current animation deformation trace
Move), Q (i) is the position of the i-th frame in current animation deformation trace.
Specifically, in former animation deformation trace, since the start frame in former animation deformation trace need not carry out displacement
Compensation, therefore, after carrying out bit shift compensation, V (1)=0.It is follow-up each in addition to start frame in former animation deformation trace
The displacement for the object that frame (for example, i-th frame) is generated relative to the (i-1)-th frame is V (i)=P (i)-P (i-1), then carries out bit shift compensation
Later, the i-th frame becomes V (i)=P (i)-P (i-1)+M (i) relative to the displacement of the object of the (i-1)-th frame.It should be understood that due to
The i-th frame in former animation deformation trace is that tool is directive relative to the displacement of the (i-1)-th frame, and M (i) is also the displacement with direction
Compensation, therefore, V (i) are also a vector.As shown in Figure 4.
It is after the displacement of each frame in obtaining current animation deformation trace, i.e., each in current animation deformation trace
The new position Q (i) of frame becomes：
Q (1)=P (1), i.e. initial position is constant；
Q (i)=Q (i-1)+V (i), i.e., the follow-up position per frame are on the basis of previous frame position plus between this two frame
Displacement V (i), wherein displacement have done bit shift compensation.
In this way, the position Q (i) of each frame of current animation deformation trace is calculated by formula (3)~(6), successively
The position Q (i) for connecting each frame forms current animation deformation trace.
Fig. 5 is shown after step S103, is obtained object and is animated the actual motion track after displacement stretches.
In the embodiment of the present invention, in the target point of current animation actual needs mobile target point and former animation deformation trace
Between when have differences, the displacement difference between this two target points can be shared on each frame of animation, and point
The mode at booth is so that the size of the bit shift compensation of each frame is all proportional to the shift length of this frame in former animation, Er Qiesuo
Some bit shift compensations are added, i.e. and M (1)+M (2)+...+M (N)=D-P (N), i.e., total bit shift compensation are exactly equal to two target points
Between displacement difference, therefore carry out in the way of in step S103 driven object movement, just can be in last frame by object
It is moved at target point D, achievees the purpose that animation displacement is stretched to target point.Obviously the animation displacement of each frame stretches table simultaneously
It is now consistent with the performance of the speed of original animation, i.e., inside former animation deformation trace, if a certain section of time shifting is compared
Few, then the stretching of this period is also fewer.Fig. 5 shows this result, it can be seen that in inside former animation deformation trace
Between a section move it is fewer, it is corresponding stretching track inside change in displacement (i.e. bit shift compensation) it is also fewer, in this way
Allowing for entire drawing process has certain semanteme, meets the expectation that player shows this animation.As a comparison, Fig. 6 is aobvious
Show and animation displacement stretching is carried out to the former animation deformation trace of Fig. 2 using the method for the animation displacement Uniform Tension of the prior art
Result schematic diagram afterwards, Fig. 6 is using the animation displacement stretching mode for temporally uniformly sharing displacement difference, i.e., the displacement of each frame
Compensation is equal to (D-P (N))/(N-1) (first frame needs not compensate for, subsequent all uniformly to share displacement difference).It can be seen that
It can not accomplish the adaptivity that animation displacement stretches in this way, it is bigger in intermediate displacement fewer stage and other displacements
Stage does not have difference on bit shift compensation, inconsistent with the rhythm of original animation deformation trace faster or slower.
