您可以向 3D 地图添加镜头路径动画，为用户提供更具沉浸感的体验。镜头路径动画可以飞往地图上的某个点，也可以围绕该点飞行。
前往
以下代码示例演示了如何以动画方式将镜头移动到 3D 地图上的
特定点，方法是调用
flyCameraTo
方法。
// Add imports and define constants
import com.google.android.gms.maps3d.model.latLngAltitude
const val EMPIRE_STATE_BUILDING_LATITUDE = 40.748233
const val EMPIRE_STATE_BUILDING_LONGITUDE = -73.985663
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.flyCameraTo(
flyToOptions {
endCamera = camera {
center = latLngAltitude {
latitude = EMPIRE_STATE_BUILDING_LATITUDE
longitude = EMPIRE_STATE_BUILDING_LONGITUDE
altitude = 212.0 // in meters
}
heading = 34.0 // bearing in degrees
tilt = 67.0 // relative to vertical
range = 750.0 // distance away from the focal point in meters
roll = 0.0 // roll relative to horizontal
}
durationInMillis = 2_000
}
)
围绕飞行
以下代码示例演示了如何通过
调用 flyCameraAround
方法，以动画方式将镜头围绕 3D 地图上的特定点飞行。
// Add imports and define constants
import com.google.android.gms.maps3d.model.latLngAltitude
const val EMPIRE_STATE_BUILDING_LATITUDE = 40.748233
const val EMPIRE_STATE_BUILDING_LONGITUDE = -73.985663
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.flyCameraAround(
flyAroundOptions {
center = camera {
center = latLngAltitude {
latitude = EMPIRE_STATE_BUILDING_LATITUDE
longitude = EMPIRE_STATE_BUILDING_LONGITUDE
altitude = 212.0
}
heading = 34.0
tilt = 67.0
range = 750.0
roll = 0.0
}
durationInMillis = 5_000
rounds = 1.0 // Number of rotations - can be fractional
}
)
