When I don't rotate the player, he doesn't have this lines...
This the rotate code:
if(ySpeed != 0 || xSpeed != 0)
deg = fmod(atan2(yP-(yP+ySpeed),xP-(xP+xSpeed))/3.14159265f*180.f,360.f);
glPushAttrib(GL_TRANSFORM_BIT);
glMatrixMode(GL_TEXTURE);
glLoadIdentity();
glPushMatrix();
glTranslatef(0.5f, 0.5f, 0.f);
glRotatef(deg, 0.f, 0.f, 1.f);
glTranslatef(-0.5f,-0.5f, 0.f);
glMatrixMode(GL_MODELVIEW);
glPopAttrib();
glEnable (GL_BLEND);
glColor4f(1.0f,1.0f,1.0f,1.0f);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glBegin(GL_QUADS); //draw...
glTexCoord2d(1.0,1.0);glVertex3f( xP, yP2, 0);
glTexCoord2d(0.0,1.0);glVertex3f( xP2, yP2, 0);
glTexCoord2d(0.0,0.0);glVertex3f( xP2, yP, 0);
glTexCoord2d(1.0,0.0);glVertex3f( xP, yP, 0);
glEnd();
glMatrixMode(GL_TEXTURE);
glPopMatrix();
glMatrixMode(GL_MODELVIEW); glDisable (GL_BLEND);
