◆ RADAR_CheckUFOSensored()

bool RADAR_CheckUFOSensored	(	radar_t *	radar,
		const vec2_t	posRadar,
		const aircraft_t *	ufo,
		bool	detected )

Check if the specified UFO is inside the sensor range of the given radar.

Parameters

[in,out]	radar	radar that may detect the UFO.
[in]	posRadar	Position of `radar`
[in,out]	ufo	aircraft that should be checked.
[in]	detected	Is the UFO already detected by another radar? (Beware: this is not the same as ufo->detected)

Returns: true if the aircraft is inside sensor and was sensored
