Function Documentation

static u32 CalcOwnerMask ( player_id_t  owner )

inlinestatic

Convert an owner ID (-1 = unowned, 0 = gaia, 1..30 = players) into a 32-bit mask for quick set-membership tests.

static u32 CalcPlayerLosMask ( player_id_t  player )

inlinestatic

Returns LOS mask for given player.

static u32 CalcSharedLosMask ( std::vector< player_id_t >  players )

static

Returns shared LOS mask for given list of players.

static u16 CalcVisionSharingMask ( player_id_t  player )

inlinestatic

Computes the shared vision mask for the player.

cassert

(

sizeof(EntityData)

= =24

)

static u8 GetPlayerVisibility ( u32  visibilities, player_id_t  player  )

inlinestatic

Computes the 2-bit visibility for one player, given the total 32-bit visibilities.

static bool HasVisionSharing ( u16  visionSharing, player_id_t  player  )

inlinestatic

Test whether a player share this vision.

static bool InParabolicRange ( CFixedVector3D  v, fixed  range  )

static

Checks whether v is in a parabolic range of (0,0,0) The highest point of the paraboloid is (0,range/2,0) and the circle of distance 'range' around (0,0,0) on height y=0 is part of the paraboloid.

Avoids sqrting and overflowing.

static bool IsVisibilityDirty ( u16  dirty, player_id_t  player  )

inlinestatic

Test whether the visibility is dirty for a given LoS tile and a given player.

static bool SetPlayerSharedDirtyVisibilityBit ( u16 &  mask, player_id_t  player, bool  enable  )

static

Add/remove a player to/from mask, which is a 1-bit mask representing a list of players.

Returns true if the mask is modified.
