Input
Sketches driven by the mouse, the trackpad, and the keyboard.
| Example | What it shows |
|---|---|
| PanAndZoom | a generated chart that holds more than one screen shows, so you drag to pan and scroll to zoom. The place names are set at a text size of four units, six for the larger places, which reads as a smudge at the opening view and is crisp four zoom steps in (viewControl, viewZoom) |
| RepelGrid | a grid of dots that move away from the cursor (mouseX/mouseY) |
| Keys | steer a dot with WASD or the arrow keys, both read through one moveAxis call. Space changes the color (keyPressed), and releasing any key flashes a ring (keyReleased) |
| Pen | a broad-edged nib that reads a tablet: the chisel lies across the way the pen leans, the press sets how wide, the eraser end takes ink away, and a panel says what the stylus is sending (stylus, pressure) |
| PinchAndTurn | two fingers on the trackpad size and spin a rose (pinchScale, turnAngle), and the turn clicks its petal count a notch every fifteen degrees (fingersTurned) |
| TypedText | type and the words land on the canvas, the way a text field takes them: an accent typed with a dead key, the emoji viewer's pick, and Chinese or Japanese through an input method arrive as text (typedText, textTyped), the reading still being composed shows underlined (composingText), and a panel sets the last key beside the last text it typed |
| Drag | grab, drag, and throw balls. It uses the press and release hooks, draws the per-frame mouse - previousMouse delta as a stretch arrow, and averages the release velocity over the last few frames |
