I should have better used the wording "graphic of type" than "graphic of style" because we can set the style of grc 1 to "polygon" for example (the function again, just for the completeness here):
on mouseUp if there is no grc "poly" then create grc "poly" set style of grc "poly" to "polygon" -- 7 vertices, 1 vertix at 12 o'clock, radius 42, loc (100,100) set points of grc "poly" to regularPoints(7,42,100,100) set foreColor of grc "poly" to "0,128,128" -- teal set lineSize of grc "poly" to 2 end mouseUp -- N is the number of vertices -- x0,y0 is the center of the polygon -- r is the radius of the polygon -- b is the angle of rotation in degrees -- (positive b turns clockwise, negative b turns ccw) function regularPoints n,r,x0,y0,b put 2*pi/n into cn -- n vertices --> n+1 points if 'closed' polygon -- usually done by setting last=first -- This is here true as sin(0)=sin(2*pi) and cos(0)=cos(2*pi) put empty into pts if b=0 or b is empty then ## compute unrotated n+1 vertices of the n-sided regular polygon repeat with j=0 to n put CR & (round(r*sin(j*cn)+x0),round(-r*cos(j*cn)+y0)) after pts end repeat else ## compute *rotated* n+1 vertices of the n-sided regular polygon put sin(pi*b/180) into s; put cos(pi*b/180) into c repeat with j=0 to n put round( r*sin(j*cn)) into sx; put round(-r*cos(j*cn)) into sy put CR & ( (round(x0+c*sx-s*sy),round(y0+c*sy+s*sx)) ) after pts end repeat end if return char 2 to -1 of pts end regularPoints _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
