◆ CL_GetHitProbability()

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

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

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
