CesiumJS interaction and picking - ScreenSpaceEventHandler, multi-key KeyboardEventModifier input actions, Scene.pick, Scene.drillPick, Scene.pickPosition, Scene.snap edge snapping (1.144), mouse and touch events. Use when handling user clicks on the globe, selecting entities or 3D Tiles features, registering modifier-key shortcuts, implementing hover effects, snapping to model edges for measurement, or building drag-based interactions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CesiumJS Interaction & Picking
Version baseline: CesiumJS v1.144 (ES module imports, Ion token required).
## ScreenSpaceEventHandler
Central class for mouse, touch, and pointer events on the Cesium canvas.
**Always construct a new `ScreenSpaceEventHandler` bound to `viewer.scene.canvas`
for interaction logic** -- it isolates your listeners from Cesium's default
camera/selection handlers and is the idiomatic pattern shown across all recipes
below.
```js
import { ScreenSpaceEventHandler, ScreenSpaceEventType,
KeyboardEventModifier, defined } from "cesium";
let handler = new ScreenSpaceEventHandler(viewer.scene.canvas);
// Register a click handler
handler.setInputAction((event) => {
console.log("Clicked at", event.position.x, event.position.y);
}, ScreenSpaceEventType.LEFT_CLICK);
// With keyboard modifier (Shift+Click)
handler.setInputAction((event) => {
console.log("Shift+Click at", event.position);
}, ScreenSpaceEventType.LEFT_CLICK, KeyboardEventModifier.SHIFT);
// With multiple modifiers (Ctrl+Shift+Click, 1.142+)
handler.setInputAction((event) => {
console.log("Ctrl+Shift+Click at", event.position);
}, ScreenSpaceEventType.LEFT_CLICK, [

How to install
mdr add cesiumgs/cesiumjs-skills/cesiumjs-interaction@sha256:6787901f5ea7a3c1The line at the top of this page pins the label git:20260827.49e0612, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
