I would love a new behavior that could swap drawings or change a value based on a 9 point grid.
Point 5 would be the default state or drawing. Sliding it in any direction would adjust the value or drawings based on settings predetermined in the behavior. think of a joystick, where it doesn't just move left or right, or up ot down, it can move in all four of those directions, and can also blend them together for diagonal moves.
Use cases would include changing an expression, rotating a head or other object. This would allow not just changing between one state to another, but allow multiple possibilities. Move up for happy, down for sad, left for angry, right for scared. Etc.
You could preload a series of drawings into each of the 9 points on the grid. Or you could assign values into the grid so when you adjust the joystick it changes the values.
This sort of thing is easily possible in 3D software, or using Master Controllers in Toon Boom Harmony. It would be great to have something like this here!
If someone has a way to do this now, please let me know!
I whole-heartedly agree that this should be a feature! I have the plugin "Joysticks and Sliders" for After Effects and it makes it super easy to set up a head rig that can turn right, left, up and down via paralax. All you do is set up the default (straight-forward) view, then adjust positions, rotations, and even the paths of your shape layers/masks for each direction (Up, Down, Left, Right). Then you get a little "joystick" control that interpolates between those values to give you some nice head movement. If implemented in ChAnim, you could control this with your head tracking, the arrow keys, or the mouse.
