delta_value is the change of the value in the interpolation, i.e. it's equal to final_value - initial_value. Note: As it results from accumulating frame deltas, the time returned after the Tween has finished animating will be slightly greater than the actual Tween duration. To copy a keyframe or frame sequence by dragging, select it and Alt‑drag (Windows) or Option-drag (Macintosh) to the new location.

When you open KeyTweak, the main window will display an image of a keyboard, along with a menu bar, a Remapping section, Keyboard Control section, Specialty Buttons section, Pending Changes section, and buttons to toggle between full and half teaching modes. You can also access the KeyTweak manual here from the Help menu. And then to use this you need a key in your parent: final GlobalKey _shakeKey = GlobalKey();

Tip: By default, the control points snap to a grid. You can turn off snapping by pressing the X key while dragging the control point.

A Tween can be created by using either SceneTree.create_tween or Node.create_tween. Tweens created manually (i.e. by using Tween.new()) are invalid and can't be used for tweening values. Calling this method without arguments will make the Tween run infinitely, until either it is killed with kill, the Tween's bound node is freed, or all the animated objects have been freed (which makes further animation impossible).

Properties

Underneath the menu bar at the top of the window, the Remapping section includes a list of currently remapped keys and buttons to restore defaults and show the Raw Map. Keyboard Control is where you can select the new remapping for a chosen key. You can do this via a drop-down list and a Remap button. And then you can do something like this inside your parent body (see where "Shaker" is used around the child I want to shake): ...

To extend the duration of a keyframe, Alt‑drag (Windows) or Option-drag (Macintosh) it to the final frame of the new sequence. You can repeat this process for as many keys as you wish, defining new mappings or disabling a key's function. Once you reboot, your keyboard will be mapped as you defined while using the program. KeyTweak is ideal mainly for redefining individual keys and fixing small keyboard inconveniences, rather than changing your whole keyboard's behavior. Note: Tweens are not designed to be re-used and trying to do so results in an undefined behavior. Create a new Tween for each animation and every time you replay an animation from start. Keep in mind that Tweens start immediately, so only create a Tween when you want to start animating.
