Function Documentation

void CC_DLL
cocos2d::ccVertexLineToPolygon
( CCPoint *  points,
float  stroke,
ccVertex2F vertices,
unsigned int  offset,
unsigned int  nuPoints 
)

converts a line to a polygon

bool CC_DLL
cocos2d::ccVertexLineIntersect
( float  Ax,
float  Ay,
float  Bx,
float  By,
float  Cx,
float  Cy,
float  Dx,
float  Dy,
float *  T 
)

returns whether or not the line intersects

CCRect CC_DLL
cocos2d::CCRectFromString
( const char *  pszContent)

Returns a Core Graphics rectangle structure corresponding to the data in a given string.

Parameters
pszContentA string object whose contents are of the form "{{x,y},{w, h}}", where x is the x coordinate, y is the y coordinate, w is the width, and h is the height. These components can represent integer or float values. An example of a valid string is "{{3,2},{4,5}}". The string is not localized, so items are always separated with a comma.
Returns
A Core Graphics structure that represents a rectangle. If the string is not well-formed, the function returns CCRectZero.
CCPoint CC_DLL cocos2d::ccpForAngle ( const float  a)

Converts radians to a normalized vector.

Returns
CCPoint
Since
v0.7.2
float CC_DLL cocos2d::clampf ( float  value,
float  min_inclusive,
float  max_inclusive 
)

Clamp a value between from and to.

Since
v0.99.1
CCPoint CC_DLL cocos2d::ccpClamp ( const CCPoint &  p,
const CCPoint &  from,
const CCPoint &  to 
)

Clamp a point between from and to.

Since
v0.99.1
CCPoint CC_DLL cocos2d::ccpFromSize ( const CCSize &  s)

Quickly convert CCSize to a CCPoint.

Since
v0.99.1
CCPoint CC_DLL cocos2d::ccpCompOp ( const CCPoint &  p,
float(*)(float)  opFunc 
)

Run a math operation function on each point component absf, fllorf, ceilf, roundf any function that has the signature: float func(float); For example: let's try to take the floor of x,y ccpCompOp(p,floorf);.

Since
v0.99.1
CCPoint CC_DLL cocos2d::ccpLerp ( const CCPoint &  a,
const CCPoint &  b,
float  alpha 
)

Linear Interpolation between two points a and b.

Returns
alpha == 0 ? a alpha == 1 ? b otherwise a value between a..b
Since
v0.99.1
bool CC_DLL
cocos2d::ccpLineIntersect
( const CCPoint &  p1,
const CCPoint &  p2,
const CCPoint &  p3,
const CCPoint &  p4,
float *  s,
float *  t 
)

A general line-line intersection test.

Parameters
p1is the startpoint for the first line P1 = (p1 - p2)
p2is the endpoint for the first line P1 = (p1 - p2)
p3is the startpoint for the second line P2 = (p3 - p4)
p4is the endpoint for the second line P2 = (p3 - p4)
sis the range for a hitpoint in P1 (pa = p1 + s*(p2 - p1))
tis the range for a hitpoint in P3 (pa = p2 + t*(p4 - p3))
Returns
bool indicating successful intersection of a line note that to truly test intersection for segments we have to make sure that s & t lie within [0..1] and for rays, make sure s & t > 0 the hit point is p3 + t * (p4 - p3); the hit point also is p1 + s * (p2 - p1);
Since
v0.99.1
bool CC_DLL
cocos2d::ccpSegmentIntersect
( const CCPoint &  A,
const CCPoint &  B,
const CCPoint &  C,
