Function Documentation

void CP_GetRandomPosOnGeoscape	(	vec2_t	pos,
		bool	noWater
	)

Determines a random position on geoscape.

Parameters

[out]	pos	The position that will be overwritten. pos[0] is within -180, +180. pos[1] within -90, +90.
[in]	noWater	True if the position should not be on water

See also: CP_GetRandomPosOnGeoscapeWithParameters

Note: The random positions should be roughly uniform thanks to the non-uniform distribution used.; This function always returns a value.

bool CP_GetRandomPosOnGeoscapeWithParameters	(	vec2_t	pos,
		const linkedList_t *	terrainTypes,
		const linkedList_t *	cultureTypes,
		const linkedList_t *	populationTypes,
		const linkedList_t *	nations
	)

Determines a random position on geoscape that fulfills certain criteria given via parameters.

Parameters

[out]	pos	The position that will be overwritten with the random point fulfilling the criteria. pos[0] is within -180, +180. pos[1] within -90, +90.
[in]	terrainTypes	A linkedList_t containing a list of strings determining the acceptable terrain types (e.g. "grass") May be nullptr.
[in]	cultureTypes	A linkedList_t containing a list of strings determining the acceptable culture types (e.g. "western") May be nullptr.
[in]	populationTypes	A linkedList_t containing a list of strings determining the acceptable population types (e.g. "suburban") May be nullptr.
[in]	nations	A linkedList_t containing a list of strings determining the acceptable nations (e.g. "asia"). May be nullptr

Returns: true if a location was found, otherwise false

Note: There may be no position fitting the parameters. The higher RASTER, the lower the probability to find a position.

See also: LIST_AddString; LIST_Delete

Note: When all parameters are nullptr, the algorithm assumes that it does not need to include "water" terrains when determining a random position; You should rather use CP_GetRandomPosOnGeoscape if there are no parameters (except water) to choose a random position

Todo:

cache the counted hits

Todo:: add EQUAL_EPSILON here?

void GEO_DrawMarkers ( const uiNode_t * node )

Draws all ufos, aircraft, bases and so on to the geoscape map (2D and 3D)

Parameters

[in] node The menu node which will be used for drawing markers.

Note: This is a drawing function only, called each time a frame is drawn. Therefore you should not use this function to calculate eg. the distance between 2 items on the geoscape (you should instead calculate it just after one of the items moved – distance is not going to change when you rotate the earth around itself and the time is stopped eg.).
