設定標記衝突行為

選取平台： Android iOS JavaScript

您可以自訂新增至 3D 地圖的標記碰撞行為。

地圖檢視畫面，顯示標記衝突行為

下列程式碼範例說明如何設定 Marker 結構體的 collisionBehavior，指定標記與其他標記或地圖標籤衝突時應呈現的行為。

Map(camera: $camera, mode: .hybrid) {
  Marker(
     position: .init(
        latitude: 37.794724,
        longitude:  -122.39442,
        altitude: 100.0),
      altitudeMode: .relativeToMesh,
      collisionBehavior: .optionalAndHidesLowerPriority,
      extruded: true,
      label: "Marker 1"
    )
