Move the squares to change the curvature To add a curve, simply click somewhere along the spline (similar to flgma) Note that you may also move the first and the last points along the y-axis (up and down) The button with two arrows pointing at one another reverse the easing. The other buttons are intuitive I hope. Hover your mouse in the top left corner of the window to change clamp settings on the control points (angle, angle+length, broken). Try each of the settings out to better understand exactly what each does. The default clamp setting is angle (same as the good ol' SVE) Press "V" to play your easing. Press "SPACE" to save your easing. Follow the instructions in the "SAVE" list to port the easing to your own project. Press "SPACE" to close the "SAVE" list when opened. I'll add importing and presets later. Don't even ask bro ;-; Same with clickable icons for playing, saving, settings, and zooming in and out.
The editor is laughably unoptimized. Note that I was originally developing this for just myself, so some things are still ugly. Thanks to Scratch for Undo/Redo & Flip Icon ref., and some website for the Delete icon. Sorry designer friends I was lazy...icl it looks good tho
