qboolean CL_BattlescapeRunning ( void )

Check whether we already have actors spawned on the battlefield.

See also:: CL_OnBattlescape

Returns:: true when we are in battlefield and have soldiers spawned (game is running)

int CL_GetHitProbability ( const le_t * actor )

Calculates chance to hit if the actor has a fire mode activated.

Parameters:

[in] actor The local entity of the actor to calculate the hit probability for.

Todo:: The hit probability should work somewhat differently for splash damage weapons. Since splash damage weapons can deal damage even when they don't directly hit an actor, the hit probability should be defined as the predicted percentage of the maximum splash damage of the firemode, assuming the projectile explodes at the desired location. This means that a percentage should be displayed for EVERY actor in the predicted blast radius. This will likely require specialized code.

Todo:: use LE_FindRadius

static float CL_LookupErrorFunction ( float z ) [static]

calculate approximate erf, the error function http://en.wikipedia.org/wiki/Error_function uses lookup table and linear interpolation approximation good to around 0.001. easily good enough for the job.

Parameters:

[in] z the number to calculate the erf of.

Returns:: for positive arg, returns approximate erf. for -ve arg returns 0.0f.

qboolean CL_OnBattlescape ( void )

Check whether we are in a tactical mission as server or as client. But this only means that we are able to render the map - not that the game is running (the team can still be missing - see CL_BattlescapeRunning).

Note:: handles multiplayer and singleplayer

See also:: CL_BattlescapeRunning

Returns:: true when we are in battlefield

qboolean CL_OutsideMap	(	const vec3_t	position,
		const float	delta
	)

Checks whether give position is still inside the map borders.

Parameters:

`[in]`	position	The position to check (world coordinate)
`[in]`	delta	The delta from the map boundaries. Positive values to make the position being earlier out of the map, negative values to let the position be later out of the map

Returns:: true if the given position is out of the map boundaries, false otherwise.
