Unity3d automatic generation of 2D animation _ Game development and technology

About the automatic generation of animation, rain pine Momo has a relatively complete article, links in this click to open the link

Generating Animationclip, controller, and setting state are all references to the code he provides, and here I would like to add an anchor point to the 2d texture.

The main look at the code here, it is worth mentioning that the set custom anchor point must be set to the Spritealignment 9 (customer), otherwise the set of pivot will not work.

    [MenuItem ("Jygame/buildclip")] static void Buildclip () {//animationxml XML = Resourcemanager.get
        Resourcemanager.init ();

        list<string> actionlist = new list<string> ();
            foreach (Var d in Targetdir.getdirectories ()) {string animationname = D.name;
            Debug.Log ("Building" + animationname); if (resourcemanager.get<jygame.animationnode> (animationname) = = null) {debug.logwarning
                ("error, cannot find the anchor description in XML!" + Animationname);
            Continue ///Adjust anchor foreach (Var f in new DirectoryInfo (D.fullname + "\\rawdata"). GetFiles ("*.png")) {string[] paras = f.name.replace (". png", "").
                Split ('-');
                string animation = Paras[0];
                String action = Paras[1]; int count = Int.

                Parse (paras[2]);
                Animationimage img = null;
                Try{img = resourcemanager.get<jygame.animationnode> (animation).
                Getgroup (Action). Images[count];
                    catch {Debug.Log ("The description of the file is not found, delete" + f.fullname);
                    File.delete (F.fullname);
                Continue
