Hi Guys, Here are the steps to make the first tumble in a slinky-like movement. ——————————————————————————- —————————— Create/Standard Primitives/Cylinder1 Radius 10 Height 50 Height Segments 10 Animate On Goto Frame 10 Modify/Bend Angle 180 Direction 0 Bend Axis Z Animate Off Create/Helpers/General/Dummy (Im using the dummy as a visual guide) (This step will be replaced with a better technique for positioning the cylinder in future steps) Scale and Move the Dummy so that its positioned directly under the bent top of the cylinder. (see dummy placement and scale at frame 10 in slinky-tut.max) Animate On Time Configure/Frame:Ticks Increment Time (Should be 10:1) Select Cylinder1 Modify Bend Angle 0 Increment Time twice (Should be 10:3) Rotate the Cylinder a tad about its Local Y (any amount). In TrackView Filter/Animated Tracks Only Expand Objects/Cylinder/Transform & Modified Object/Bend Zoom Time so that you can see the sub-frame tics displayed and you have visible space between the keys on 10.1 and 10.3. Select-Copy the rotation key on frame 0 and move it to 10.2. Select the rotation key on 10.3 and then right click for Key-Info. Verify that the rotation angle is 180. For the each Rotation Key(0,10.2, 10.3), Change to tension to 50. ** Is the following a bug? ** ** In order to the bend at 10.1 to take, Ive got to add another key at 10.2 ** Select the Bend Angle Key on 10.1, Shift-Copy the Key to 10.2. Right Click on the newly created Angle key at 10.2 bringing up Keyinfo, Cycle the spinner to the angle key at frame 1 Time 0 Change Out to Linear Time 10.0 Change In to Linear Change Out to Stair-Step Time 10.1 Change In to Stair-Step Change Out to Stair-Step Time 10.2 Change In to Stair-Step (Redundant Key?) Change Out to Stair-Step Increament Time to 10.4 Move the cylinder object so that it is sitting on top of the Dummy Select the Position Key at Time 0 Shift-Copy this key and move it to Time 10.3 Right Click on this key and cycle the Key spinner to Frame 1 Time 0 Change Out to Linear Time 10.3 Change In to Linear Change Out to Stair-Step Time 10.4 Change In to Stair-Step Change Out to Linear ** Is the following a bug? ** ** In order to the position at 10.4 to take, Ive got to add another key at 10.5 ** Shift-Copy the position key at 10.4 and move it to 10.5 Time 10.5 Change In to Linear Change Out to Linear Increment Time to 10.6 Modify/Cylinder1/Bend/Sub-Object/Center Move the Center in the Local Z so that its centered at the base where it touches the dummy. ** Is the following a bug? ** ** In order to the Animated Gizmo Center to take at 10.6, Ive got to add another key at 10.7 ** Shift-Copy the Gizmo-Center Key to 10.7. Change the Range Types for the Gizmo-Center to: Time 0 Change Out to Stair-Step Time 10.6 Change In to Stair-Step Change Out to Stair Step Time 10.7 Change In to Stair Step Change Out to Stair-Step Increment Time to 10.8 Modify/Cylinder1/Bend Angle 180 ** Is the following a bug? ** ** In order to the Animated Bend to take at 10.8, Ive got to add another key at 10.9 ** Shift-Copy the Bend Key to 10.9. Increment Time to 20.0 Modify/Cylinder1/Bend Angle -180 Change the Range Types for the Bend Angle to: Time 10.8 Change In to Stair-Step Change Out to Stair-Step Time 10.9 Change In to Stair-Step Change Out to Linear Time 20 Change In to Linear Thats all..;-)… jonas
