Hello, people. I have a function that outputs the x, y and z coordinates of a vertex after selecting it from 3D sphere mesh. Each vertex in my project also has an id. Now, I need a certain vertex, for example the vertex with the id=40 to move in a different direction, so I have to give it new x, y and z coordinates. Here is the function:

Code :void mouse(int button, int state, int x, int y) { GLint viewport[4]; GLdouble modelview[16], projection[16]; GLfloat wx=x, wy, wz; if(state!=GLUT_DOWN) return; if(button==GLUT_RIGHT_BUTTON) exit(0); glGetIntegerv(GL_VIEWPORT,viewport); y=viewport[3]-y; wy=y; glGetDoublev(GL_MODELVIEW_MATRIX,modelview); glGetDoublev(GL_PROJECTION_MATRIX,projection); glReadPixels(x,y,1,1,GL_DEPTH_COMPONENT,GL_FLOAT,&wz); gluUnProject(wx,wy,wz,modelview,projection,viewport,&ox,&oy,&oz); glutPostRedisplay(); printf("made pick on %f %f %f \n", ox, oy, oz); pick(x,y); Vertex.x=ox; Vertex.y=oy; Vertex.z=oz; processhits (nhits, buffer); if (vertexSelectat==40) { Vertex.x=-54.261713; Vertex.y=-18.614050; Vertex.z=-163.609310; } }

In my project, Vertex is defined as follows:

Code :typedef struct Vertex { float x, y, z; int id; } Vertex;

After I build the project, I get 6 errors "syntax error: missing ';' before '.' after every line where I specify Vertex coordinates. I am new to both OpenGL and C++ so sorry if this is a silly question. Waiting for some help, thank you for your time . If you request, I can attach the whole project here.
