Function Documentation

◆ CP_AddRadarCoverage()

void CP_AddRadarCoverage	(	const vec2_t	pos,
		float	innerRadius,
		float	outerRadius,
		bool	source )

Add a radar coverage (base or aircraft) to radar overlay.

Parameters

[in]	pos	Position of the center of radar
[in]	innerRadius	Radius of the radar coverage
[in]	outerRadius	Radius of the outer radar coverage
[in]	source	True if we must update the source of the radar coverage, false if the copy must be updated.

Precondition: We assume outerRadius is smaller than 180 degrees

< Alpha of the inner radar range

< Alpha of the outer radar range

< current position (in pixel)

< Bounding box of the inner radar zone

< Bounding box of the outer radar zone

Todo: add EQUAL_EPSILON here?

◆ CP_ChangeXVILevel()

void CP_ChangeXVILevel	(	const vec2_t	pos,
		float	factor )

Convert the pos into degrees and increase XVI there.

Parameters

pos	The x/y-location in the flat XVI map
factor	The factor of the XVI raise

Note: xvi rate is null when alpha = 0, max when alpha = maxAlpha

◆ CP_InitializeRadarOverlay()

void CP_InitializeRadarOverlay ( bool source )

Initialize radar overlay on geoscape.

Parameters

[in] source Initialize the source texture if true: if you are updating base radar overlay. false if you are updating aircraft radar overlay (base radar overlay will be copied to aircraft radar overlay)
