Point2D getVector	(	double	angle,
		double	speed
	)

Gets direction and length for a vector.

Parameters

angle	the angle in radians
speed	the speed of the object

Definition at line 107 of file fns.cpp.

Here is the caller graph for this function:

SDL_Surface* LoadImage ( std::string filename )

Loads supported images.

< check to see if a filename was provided.

< if not exit the function

Load the image using our new IMG_Load function from sdl-Image1.2

< check to see if it loaded properly

the image loaded fine so we can now convert it to the current display depth

Destroy the old copy

return a pointer to the newly created display compatible image

Here is the caller graph for this function:

unsigned int nextPow2 ( unsigned int i )

Rounds a number to the next power of two.

Definition at line 96 of file fns.cpp.

Here is the caller graph for this function:

float randFloat	(	float	min = `0`,
		float	max = `1`
	)

Retrieves a random floating-point number between 0 and 1.

Parameters

min	the lower bound
max	the upper bound

Returns: A random floating-point number between 0 and 1.

Definition at line 124 of file fns.cpp.

Here is the caller graph for this function:

int randInt ( int max = RAND_MAX )

Retrieves a random integer less than the given maximum.

The integer returned will be greater than or equal to 0 and less than the maximum.

    int diceroll = This.Game.RandInt(6)+1;

Parameters

max	The value that the generated random number must be less than.

Returns: A random integer in the specified range.

Definition at line 114 of file fns.cpp.

Here is the caller graph for this function:

int randInt	(	int	min,
		int	max
	)

Retrieves a random integer great than or equal to the minimum and less than the given maximum.

Parameters

min	The value that the generated random number must be greater than or equal to.
max	The value that the generated random number must be less than.

Returns: A random integer in the specified range.

Definition at line 119 of file fns.cpp.

vector<string> splitString	(	string	s,
		char	delim,
		int	rep
	)

Splits strings on delimiter.

Definition at line 130 of file fns.cpp.
