i am attempting to move 3d objects based on variables that are changed on keypress or on a timer loop, this seems pretty standard, but im missing something, and i figured you kind folks could help me out... This is a piece of code that represents the problem im having... im probably missing something simple, but here goes. I have printed the variables to the console from just about every location, and i have confirmed that they are changing but gl doesnt seem to want to use them #include <iostream> #include <stdlib.h> #ifdef __APPLE__ #include <OpenGL/OpenGL.h> #include <GLUT/glut.h> #else #include <GL/glut.h> #endif using namespace std; //////////////////////////// //PROTOTYPES //////////////////////////// void display(void); void keyboard(unsigned char key, int x, int y); void update(int value); //////////////////////////// static GLfloat x; void display() { glLoadIdentity(); glClear(GL_COLOR_BUFFER_BIT); glBegin(GL_QUADS); glVertex3f(x,1,-14); glVertex3f(x+1,1,-14); glVertex3f(x+1,2,-14); glVertex3f(x,2,-14); glEnd(); glFlush(); } void keyboard(unsigned char key, int x, int y) { } void update(int value) { x = x + 1; cout << x << endl; glutPostRedisplay(); glutTimerFunc(1000,update,0); } void changeSize(int w, int h) { if(h == 0) h = 1; float ratio = 1.0* w / h; glMatrixMode(GL_PROJECTION); glLoadIdentity(); glViewport(0, 0, w, h); gluPerspective(45,ratio,1,1000); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0.0,0.0,5.0, 0.0,0.0,-1.0, 0.0f,1.0f,0.0f); } int main(int argc, char **argv){ glutInit(&argc,argv); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE); glutInitWindowSize(500,500); glutInitWindowPosition(100,100); glutCreateWindow("Game"); glutDisplayFunc(display); glutKeyboardFunc(keyboard); glutTimerFunc(1000,update,0); glutReshapeFunc(changeSize); glClearColor(0.0,0.0,0.0,1.0); glutMainLoop(); return 0; } I have printed the variables to the console from just about every location, and i have confirmed that they are changing but gl doesnt seem to want to use them. It seems to move it when i resize the window or minimize it, so my guess is the screens not updating Thanks in advance for all your help!!

OMG forgot to glutSwapBuffers()
