\"\"<\/p>\n

Tried to follow the mecanim tutorial from here: http:\/\/www.youtube.com\/watch?v=QGXns8GemU0<\/a> (Unity 4 – Using Mecanim)<\/p>\n

Had to do few things differently to make it work..(also the current UI seems to be different from that video?)<\/p>\n

Here’s the (modified)\u00a0 steps from the video to get your own biped up & running<\/p>\n

Mecanim Biped Guy + Movement Script<\/strong><\/p>\n

    \n
  1. *Create Biped in Max *Skin it (I used some ready skinned character)<\/li>\n
  2. Export to unity as fbx<\/li>\n
  3. Select the model in unity project window<\/li>\n
  4. Inspector, [x] Create Avatar<\/li>\n
  5. *Import the whole movement animations \u00a0folder from the mecanim tutorial http:\/\/netstorage.unity3d.com\/unity\/MecanimSampleBeta7.zip<\/a><\/li>\n
  6. Create Animation Controller (in project window)<\/li>\n
  7. Assign it to your guy<\/li>\n
  8. Show\/Open Controller tab<\/li>\n
  9. Drag & drop \u201cIdle\u201d from those imported animations to the controller stage (Animations\/Idles\/Idle)\n
      \n
    1. Its highlighted in orange, so it\u2019s the default clip<\/li>\n<\/ol>\n<\/li>\n
    2. Right click: Create state > From new blend tree<\/li>\n
    3. Rename it to \u201cRuns\u201d<\/li>\n
    4. Double click it (Blend Tree)<\/li>\n
    5. *Note: Top of the controller tab,\u00a0 you have: Base Layer > Blend Tree (click \u201cBase Layer\u201d to get back to root)<\/li>\n
    6. Select your blendtree<\/li>\n
    7. Inspector: Press + (Add Motion Field)\n
        \n
      1. Add: RunLeft<\/li>\n
      2. Add: Run<\/li>\n
      3. Add: RunRight<\/li>\n<\/ol>\n<\/li>\n
      4. *Note: If you restart unity in between, its not easy to get back to editing the controller..(?)<\/li>\n
      5. To see preview: Select your Blend tree from stage, inspector has preview window at bottom\n
          \n
        1. Press play at the inspector preview window, your guy starts running<\/li>\n
        2. You can drag the Blend parameter, to blend between the 3 different runs<\/li>\n<\/ol>\n<\/li>\n
        3. Go back to base layer<\/li>\n
        4. Right click on top of \u201cidle\u201d, select Create Transition\n
            \n
          1. Connect\/drag the line to runs<\/li>\n<\/ol>\n<\/li>\n
          2. Right click on top of \u201cruns\u201d, select Create Transition\n
              \n
            1. Connect\/drag the line to idle<\/li>\n<\/ol>\n<\/li>\n
            2. Add events (press +)\n
                \n
              1. Speed (float)<\/li>\n
              2. Direction (float)<\/li>\n
              3. Jump (Boolean)<\/li>\n<\/ol>\n<\/li>\n
              4. Select the arrow going from \u201cidle\u201d to \u201cruns\u201d\n
                  \n
                1. In inspector, you see conditions (different from tutorial video)<\/li>\n
                2. Make condition: Greater : Speed : 0.1 (that means, we go to \u201cRuns\u201d, if speed value is greater than 0.1)<\/li>\n<\/ol>\n<\/li>\n
                3. Select the arrow going from \u201cruns\u201d to \u201cidle\u201d\n
                    \n
                  1. Make condition: Less : Speed : 0.1 (that means, we go to \u201cidle\u201d, if speed value is less than 0.1)<\/li>\n<\/ol>\n<\/li>\n
                  2. Drag the Jump in to stage\n
                      \n
                    1. from Animations \/ Jump \/ Jump<\/li>\n<\/ol>\n<\/li>\n
                    2. Create Transitions between Jump & Runs (to & back)\n
                        \n
                      1. Select transition line from \u201cruns\u201d to \u201cjump\u201d<\/li>\n
                      2. Make condition to: If | Jump (that means, if jump == true, we go to jump)<\/li>\n
                      3. Select transition line \u00a0from \u201cjump\u201d to \u201cruns\u201d<\/li>\n
                      4. Keep default condition: Exit Time : \u2026 (it means, at the last 10% of the animation time, we start to go back to other \u201cruns\u201d)<\/li>\n<\/ol>\n<\/li>\n
                      5. Add this script to our guy in scene (for movement)\n
                          \n
                        1. AvatarCtrl.cs (script below)<\/li>\n<\/ol>\n<\/li>\n
                        2. Select your camera\n
                            \n
                          1. Add SmoothFollow script<\/li>\n
                          2. Assign your guy as follow target<\/li>\n<\/ol>\n<\/li>\n
                          3. Test it<\/li>\n
                          4. problem: its running on wrong directions..<\/li>\n
                          5. fix: Select blend tree\n
                              \n
                            1. Set dropdown parameter: Direction (it was speed?)<\/li>\n
                            2. Uncheck [x] Automate thresholds<\/li>\n
                            3. for runleft: -1<\/li>\n
                            4. for: run: 0<\/li>\n
                            5. for: runright: 1<\/li>\n
                            6. check [x] Automate thresholds again<\/li>\n
                            7. Because GetAxis returns (-1 to 1)<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                              PROBLEMS:<\/strong><\/p>\n

                              –\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 For some reason, my biped is normal size in editor, but in play mode it explodes to 100m size..\u00a0\u00a0 Solved: Had to set model import scale to default 0.01 (instead of 0.001), but the model is 100 meters tall.. I guess need to scale it ready on 3D software..<\/p>\n

                              –\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 At first it was running in strange directions, had to do that threshold setting manually..<\/p>\n

                              –\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 In the preview window, I didn\u2019t see the animations using my biped..<\/p>\n

                              –\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Theres some large values visible on the blend window for direction.. eventhough automatic thresholds are on?<\/p>\n

                              — AvatarCtrl.cs —<\/strong><\/p>\n

                              using UnityEngine;\r\nusing System.Collections;\r\npublic class AvatarCtrl : MonoBehaviour {\r\nprotected Animator animator;\r\npublic float DirectionDampTime = 0.25f;\r\nvoid Start () {\r\nanimator = GetComponent<Animator>();\r\n}\r\nvoid Update () {\r\nanimator.SetBool("Jump", Input.GetButton("Fire1") );\r\nfloat h = Input.GetAxis("Horizontal");\r\nfloat v = Input.GetAxis("Vertical");\r\nanimator.SetFloat("Speed", h*h+v*v);\r\nanimator.SetFloat("Direction", h, DirectionDampTime, Time.deltaTime);\r\n}\r\n}\r\n<\/pre>\n

                              Some images of broken biped imports.. (character looks fine in editor, but once you hit play it explodes..)<\/p>\n
