Detailed Description

Class that handles some basic functions.

Note
The random functions are not called Random and RandomRange, because RANDOM_DEBUG does some tricky stuff, which messes with those names.

Member Function Documentation

◆ Chance()

static bool AIBase::Chance ( int  out,
int  max 
)
static

Returns approximately 'out' times true when called 'max' times.

After all, it is a random function.

Parameters
outHow many times it should return true. The value will be clamped to 0 .. MAX(int).
maxOut of this many times. The value will be clamped to 0 .. MAX(int).
Precondition
out is at most equal to max.
Returns
True if the chance worked out.

◆ ChanceItem()

static bool AIBase::ChanceItem ( int  unused_param,
int  out,
int  max 
)
static

Returns approximately 'out' times true when called 'max' times.

After all, it is a random function.

Parameters
unused_paramThis parameter is not used, but is needed to work with lists.
outHow many times it should return true. The value will be clamped to 0 .. MAX(int).
maxOut of this many times. The value will be clamped to 0 .. MAX(int).
Precondition
out is at most equal to max.
Returns
True if the chance worked out.

◆ Rand()

static int AIBase::Rand ( )
static

Get a random value.

Returns
A random value between 0 and MAX(int).

◆ RandItem()

static int AIBase::RandItem ( int  unused_param)
static

Get a random value.

Parameters
unused_paramThis parameter is not used, but is needed to work with lists.
Returns
A random value between 0 and MAX(int).

◆ RandRange()

static int AIBase::RandRange ( int  max)
static

Get a random value in a range.

Parameters
maxThe first number this function will never return (the maximum it returns is max - 1). The value will be clamped to 0 .. MAX(int).
Returns
A random value between 0 .. max - 1.

◆ RandRangeItem()

static int AIBase::RandRangeItem ( int  unused_param,
int  max 
)
static

Get a random value in a range.

Parameters
unused_paramThis parameter is not used, but is needed to work with lists.
maxThe first number this function will never return (the maximum it returns is max - 1). The value will be clamped to 0 .. MAX(int).
Returns
A random value between 0 .. max - 1.
