Function Documentation

addNew()

void cannonballs::addNew	(	LOC	mouseC,
		LOC	mouseO,
		double	HoldTime
	)

Will add a new cannonball based on the mouse start and mouse end. Mass of the ball will vary based on Hold Time

Parameters

mouseC	= Current Mouse Location in X and Y
mouseO	= Old (start of mouse click) Mouse Location in X and Y
HoldTime	= Time (in seconds) that the mouse button was held down for

Returns

void

Here is the call graph for this function:

checkCollisons()

void cannonballs::checkCollisons

(

uint

j

)

Checks ball number j is colliding with another ball and then do collisions.

Parameters

j	= the number in the array that ball we are checking is.

Returns

void (all changes if they are colliding is handled in this function).

Here is the call graph for this function:

checkOverlap()

bool cannonballs::checkOverlap	(	BOX	A,
		BOX	B
	)

Checks if two boxes overlap

Parameters

A	= Box for ball A
B	= Box for ball B

Returns

TRUE / FALSE if they overlap and therefore collide

clean_up()

void cannonballs::clean_up

(

void

)

Removes any "dead" balls/rope from the balls/rope vector and shrinks it to reduce memory usage

doCollide()

void cannonballs::doCollide	(	uint	numA,
		uint	numB
	)

Will calculate the new velocities of two balls that are colliding

The equations used to get the resulting velocities.

Parameters

numA	= the number in the array ball A is
numB	= the number in the array ball B is

Returns

void (everything is handled inside the function)
