Classes
class	Point2D
	2D position or vector placed here because of general access More...
class	Size2D
	Just for more logical names for sizes of objects. More...

Macros
#define	foritr(a, b)   for(auto a=b.begin(),end=b.end();a!=end;++a)
	This allows you to iterate over things with iterators without too much pain. More...
#define	foritrNoInc(a, b)   for(auto a=b.begin(),end=b.end();a!=end;)
	This allows you to iterate over things with iterators but does not actuall increment the iterator allowing the user to iterate instead. More...

typedef void(*	Behavior )()
	Behaviors use functions that take nothing and return nothing. More...

Macro Definition Documentation

#define foritr	(		a,
			b
	)		for(auto a=b.begin(),end=b.end();a!=end;++a)

This allows you to iterate over things with iterators without too much pain.

Parameters

a	The variable name to contain the iterated object
b	The object to iterate over

Definition at line 47 of file fns.h.

#define foritrNoInc	(		a,
			b
	)		for(auto a=b.begin(),end=b.end();a!=end;)

This allows you to iterate over things with iterators but does not actuall increment the iterator allowing the user to iterate instead.

Parameters

a	The variable name to contain the iterated object
b	The object to iterate over

Definition at line 54 of file fns.h.

Function Documentation

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

Definition at line 11 of file fns.cpp.

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.
