curve - Is there any way to draw curved lines or rectangles in Andengine? -

i have draw curved lines or rectangles in andengine. please tell me way if know.

ok, rectangle class draws rectangles, line class draws lines.

rectangle rect = new rectangle(float px, float py, float pwidth, float pheight, vertexbufferobjectmanager pvertexbufferobjectmanager) 

you set position, width , height here. put vertex buffer object manager there too, , you're go.

bezier curves harder do, since there no curve class nor beziercurve. use linestrip class:

    final vertexbufferobjectmanager vbom = engine.getvertexbufferobjectmanager();     final highperformancelinechainvertexbufferobject pleftcurblinechainvbom = new highperformancelinechainvertexbufferobject(vbom, trianglecount * 3, drawtype.dynamic, true, leftcurb.vertexbufferobjectattributes_default);  linestrip leftcurb = new linestrip(0, 0, 2f, 300, pleftcurblinechainvbom){           @override         protected void onmanagedupdate(final float psecondselapsed) {             super.onmanagedupdate(psecondselapsed);             drawbybezier(curveoffset);          };          void drawbybezier(float curveoffset){                (int triangleindex = 0; triangleindex < 300; triangleindex++) {                  this.setx(triangleindex, getbezier(triangleindex, curvexp1, curvexcontrol, curvexp2));                 this.sety(triangleindex, getbezier(triangleindex, curveyp1, curveycontrol, curveyp2));              }         } 

you calculate curve this:

public float getbezier(float triangleindex, float p1x, float pcx, float p2x){              float t = triangleindex / 300;             float tt = t * t;             float u = 1 - t;             float uu = u * u;              float bezier = (uu * p1x) + (2 * u * t * pcx) + (tt * p2x);              return bezier;          } 

of course not have in onmanagedupdate - code, since modify curve there. number 300 parameter linestrip , in getbezier method doesnt have 300, may lower or higher, must same in both places. if want have bezier curve (100, 100) (400, 300) control point @ (200, 350) like:

    this.setx(triangleindex, getbezier(triangleindex, 100, 200, 400));     this.sety(triangleindex, getbezier(triangleindex, 100, 350, 300)); 

hope works too.
