Access feature in drawFinsihCondition?

[iboates]

How can I access the geometry of the feature just drawn in a :raw-finish-condition function?

I have a draw interaction:

      <vl-interaction-draw
        v-if="isDraw"
        :active="isDrawOrModify"
        :source="activeLayerIdent"
        :type="activeLayerType"
        :finish-condition="drawFinishCondition"
        @drawend="handleDrawFeature"
      />

And the method:

    drawFinishCondition(e) {

      if (["demander", "producer"].includes(this.activeLayerIdent)) {
        let clickPoint = point(e.coordinate);
        for (const feature of this.restrictedAreaCollection.features) {
          if (booleanContains(feature, clickPoint)) {
            return false
          }
        }
      } else if (this.activeLayerIdent === "restrictedArea") {
        console.log(e);
      }

      return true
    },

If this.activeLayerIdent === "restrictedArea", then I am unable to get the geometry of the just-drawn feature from e. I need to check it against some other data to see if it is valid before allowing it to be drawn. How can I do this?

Hello @iboates , you can store a ref to the current drawing ol/Feature instance in drawstart event.

<vl-interaction-draw @drawstart="onDrawStart" />

onDrawStart (evt) {
  this.drawingFeature = evt.feature // instance of ol/Feature
}

Then in the finish condition callback you can access current drawing feature geometry via getGeometry() method. https://openlayers.org/en/v6.15.1/apidoc/module-ol_Feature-Feature.html#getGeometry Take a note that openlayers geometry objects will have coordinates in map view projection (EPSG:3857 by default)
