Random

Random number generation utilities.

Header: #include <asw/modules/random.h>
Namespace: asw::random

Functions

random (int)

int random(int max);

Generate a random integer between 0 and max.

random (float)

float random(float max);

Generate a random float between 0 and max.

between (int)

int between(int min, int max);

Generate a random integer between min and max (inclusive). If min is greater than max, the two values are swapped.

between (float)

float between(float min, float max);

Generate a random float between min and max. If min is greater than max, the two values are swapped.

chance

bool chance();

Generate a random boolean (50/50).

bool chance(float chance);

Generate a random boolean with a given probability of being true.

Parameter	Type	Description
chance	float	Probability of returning true (0.0 - 1.0)

Example

// Random integer 0-99
int roll = asw::random::random(99);

// Random float in range
float speed = asw::random::between(50.0f, 150.0f);

// Random direction
float angle = asw::random::between(0.0f, 6.2832f);

// 30% chance to spawn powerup
if (asw::random::chance(0.3f)) {
  // spawn powerup
}

// Coin flip
bool heads = asw::random::chance();
