This function can be used to specify the angle of the cone in which the weather radar will display rainfall. Note that this is only useful if the fsMapViewSetWeatherRadarMode has been set to horizontal or vertical.



bool fsMapViewSetWeatherRadarConeAngleInRadians(
    FsContext ctx,
    FsTextureId id,
    float fConeAngle



Parameters Description
ctx A value of type FsContext provided as an argument of the gauge callback.
id The MapView render ID as returned by the function fsMapViewCreate.
fConeAngle The angle of the "cone of vision" for the weather radar, expressed in radians, from 0 to 2\(pi\).



Return Values

Returns false if:

  • no texture matches the given MapView ID
  • the ctx is invalid

Otherwise it will return true.
