njDrawLine2D	Japanese
Draws lines on a 2D screen.

FORMAT

#include <Ninja.h> 
void njDrawLine2D( *p, n, pri, attr )
NJS_POINT2COL *p 
Int n 
Float pri 
Uint32 attr

PARAMETERS

*p
list of coordinates of end points of lines to be drawn
n
number of lines to be drawn
pri
priority (used as Z value)
attr
attributes (specifies drawing method)

RETURN VALUE

None

FUNCTION Draws n lines. Valid attributes are used to draw n lines using point data given in the screen coordinate system. NJD_DRAW_NORMAL Drawing of independent lines. NJD_DRAW_FAN Drawing of radial lines. NJD_DRAW_CONNECTED Drawing of connected lines. NJD_TRANSPARENT Translucent drawing. NJD_USE_TEXTURE Drawing with texture. The following five attributes can be specified. These attributes can be used in mutually consistent combinations by using the "|" character as a delimiter.

EXAMPLE

Sint32 i;
NJS_POINT2COL	p2c[100];
NJS_POINT2	p[100];
NJS_COLOR	col[100];

p2c.p = p;
p2c.col = col;
p2c.tex = NULL;
p2c.num = 100;

for(i=0;i<100;i++){
  p2c.p[i].x = (Sint16)(njRandom() * 640.f);
  p2c.p[i].y = (Sint16)(njRandom() * 480.f);
  p2c.p[i].col.color = (Sint32)(njRandom() * 0xFFFFFFFF);
}

njDrawLine2D(p,100,-2.f,NJD_DRAW_NORMAL|NJD_TRANSPARENT);

NOTES The NJD_DRAW_NORMAL attribute can be omitted when it is used in combination with other attributes.
