Abstract
The invention provides a method for increasing the loading speed of a Unity3d bone animation plug-in SmoothMoves. According to the method, a trigger frame and animationfilm edition data in a scriptBoneAnimation in a SmoothMoves animation file are dissociated and stored in an established script, so that both the trigger frame and the animationfilm edition in the bone animationcontain no data, that is, the data stored in the bone animation are greatly reduced. Compared with a same SmoothMoves animation file, the method does not need to deeply and repeatedly copy a great amount of repeated trigger frames or animation edition data, but only one same part of data shared by script objects established according to instantiation needs to be quoted, the times of GCAlloc are reduced, and meanwhile the memory usage is reduced.

Embodiment
For better the present invention being described, hereby with some preferred embodiments, and accompanying drawing is coordinated to elaborate to the present invention, specific as follows:
As shown in Figure 1, the inventive method comprises two steps, specific as follows:
Step S1: pull out trigger frame and animated clip from the skeleton cartoon of animation file, and form trigger frame list and animated clip list respectively;
Step S2: during each instantiation skeleton cartoon, first described trigger frame list and animated clip list are loaded separately, then quote for skeleton cartoon interpolation is corresponding.
Wherein, step S1 specifically comprises 4 steps, and as shown in Figure 2, existing composition graphs 3 illustrates the implementation of step S1, specific as follows:
For a SmoothMoves animation animationT, the size of the trigger frame (BoneAnimation.triggerFrames) of its skeleton cartoon is 200K byte, and animated clip (BoneAnimation.mAnimationClips) size of skeleton cartoon is 100K byte.
S11: the scripting object creating skeleton cartoon.
Be specially, create scripting object (ScriptObject) example, this scripting object called after SMAnimationData(is as shown in Figure 3), wherein, SMAnimationData is the sky table of data to be filled.
S12: create trigger frame list and animated clip list in scripting object.
Be specially, in SMAnimationData, add member's trigger frame list (triggerFrames) of trigger frame (TriggerFrame) array.
In SMAnimationData, add member's animated clip list (mAnimationClips) of lightweight animated clip (AnimationClipSM_Lite) array simultaneously.
S13: the trigger frame of original skeleton cartoon is copied in described trigger frame list, and empty original skeleton cartoon trigger frame.
The trigger frame (BoneAnimation.triggerFrames) of skeleton cartoon is copied in the trigger frame list (SMAnimationData.triggerFrames) of scripting object, and empties BoneAnimation. triggerFrames.
S14: the animated clip of original skeleton cartoon is copied in described animated clip list, and empties the animated clip of original skeleton cartoon.
The animated clip (BoneAnimation.mAnimationClips) of skeleton cartoon is copied in the animated clip list (SMAnimationData.mAnimationClips) of scripting object, and empties BoneAnimation.mAnimationClips.
After step S1 process, obtain scripting object scriptDataT, wherein contain former animation BoneAnimation.triggerFrames and BoneAnimation.mAnimationClips, respective size is still 200K and 100K byte.
After executing each step of above-mentioned S1, adopt the mode of instantiation to load Unity3d skeleton cartoon plug-in unit SmoothMoves, namely perform step S2, as shown in Figure 4, step S2 specifically comprises two steps, specific as follows:
S21: the pre-loaded described scripting object comprising trigger frame list and animated clip list;
As described in S13 and S14 step, after aforementioned step process, trigger frame (BoneAnimation.triggerFrames) in skeleton cartoon and animated clip (BoneAnimation.mAnimationClips) have been empty, no longer occupy a large amount of memory headroom.
And these data have been stored in scripting object, therefore before the arbitrary skeleton cartoon of instantiation, need the scripting object that this skeleton cartoon pre-loaded is corresponding, for obtaining corresponding trigger frame and animated clip information during instantiation.
The load mode of scripting object is without the need to doing any special processing, identical with the load mode of existing skeleton cartoon itself.
S22: instantiation skeleton cartoon is also quoted for its trigger frame and animated clip add.
Skeleton cartoon itself, because be blanked trigger frame and animated clip two major parts data, comparatively fasterly can complete instantiation.
Skeleton cartoon after instantiation, because trigger frame and animated clip are cleared, cannot complete its existing work.Now just need by pre-loaded scripting object, for skeleton cartoon adds relevant quoting, be specially:
Trigger frame (BoneAnimation.triggerFrames) in skeleton cartoon is pointed to the trigger frame list (SMAnimationData. triggerFrames) in scripting object by l.
Animated clip (BoneAnimation.mAnimationClips) in skeleton cartoon is pointed to the animated clip list (SMAnimationData. mAnimationClips) in scripting object by l.
After aforesaid operations, when will there is 20 animationT animations in scene of game simultaneously, then before use method of the present invention, 20 skeleton cartoons (BoneAnimation) will be produced, corresponding trigger frame (triggerFrames) just has 20 parts, total size is 4000K byte, and animated clip (mAnimationClips) also has 20 parts, and total size is 2000K byte.And after using the method for this invention, only store a scripting object scriptDataT.20 animationT animation still corresponding 20 BoneAnimation, but itself triggerFrames and mAnimationClips all points to the trigger frame list (scriptDataT.triggerFrames) of scripting object and the animated clip list (scriptData.mAnimationClips) of scripting object, instead of 20 parts of copies independent of each other.I.e. 20 animation files, only have a triggerFrames and mAnimationClips data, size is still respectively 200K and 100K byte, as shown in Figure 5.
Embodiment two:
Outside the present embodiment is different from embodiment one divided by lower part, other parts are all identical with embodiment one: specific as follows:
After the copy of step S13, also can further optimize the trigger frame of skeleton cartoon as required, as shown in Figure 6, this trigger frame to skeleton cartoon is optimized and specifically comprises the following steps:
S131: set up trigger frame bone set (trggerFrameBoneSet), comprises some trigger frame bones (TrggerFrameBone) that attribute is different in this trigger frame bone set.
S132: set up skeleton cartoon trigger frame array (BoneAnimation. trggerFrames), several trigger frame (TriggerFrame) are comprised in skeleton cartoon trigger frame array, trigger frame is for key assignments with the index of animated clip (clipIndex) and frame (frame), and all bone key frame informations stored in each trigger frame in the respective frame of corresponding animated clip, i.e. trigger frame bone list (TriggerFrame. trggerFrameBones), this list comprises some trigger frame bones (TriggerFrameBone).
S133: the concordance list each trigger frame all being set up to a correspondence, stores the index of all trigger frame bones in the trigger frame of its correspondence in the set of above-mentioned trigger frame bone in this concordance list.This process is specially: choose the trigger frame (i.e. element tf) in skeleton cartoon trigger frame array (BoneAnimation. trggerFrames), for tf sets up trigger frame bone concordance list (triggerFrameBoneIndexes), namely the whole trigger frame bone be respectively in tf sets up index, and the index of each trigger frame bone corresponds to the identical trigger frame bone of an attribute in the set of above-mentioned trigger frame bone.
After each trigger frame all being set up to corresponding concordance list, remove whole trigger frame bones of this trigger frame.
S134: the concordance list of each trigger frame of skeleton cartoon is copied to each trigger frame corresponding position in trigger frame list, and empty the trigger frame in trigger frame list.
After further optimizing the trigger frame of skeleton cartoon, the data volume of skeleton cartoon trigger frame will be less, not repeat them here.
In the middle of above-mentioned instantiation skeleton cartoon process, trigger frame and the animated clip of skeleton cartoon is copied without the need to the degree of depth, but only quoting of skeleton cartoon is pointed to the trigger frame list that pulls out and animated clip list, namely when carrying out multiple copies to same animation file, only need to quote the same a trigger frame list corresponding to this skeleton cartoon and animated clip list, effectively reduce the data volume that skeleton cartoon in instantiation process copies.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those skilled in the art is in the technical scope that the present invention discloses; the distortion do the present invention or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
