You can put printf("passed here
"); everywhere you want to check where the program execution is currently running.
By the way, Glut is event driven, so it only reacts to events. If you want some code to be executed when nothing happens, use glutIdleFunc.
I tried that too and I am using devcpp in that its not showing the output from printf statement.
You should build a command-line project for that.
Did you consider a better-suited toolkit for you, such as GLFW ?
GLFW??? what is this?? I have never heard about it.
help plz
I think glut is sufficient for his current needs, but we can’t read the docs for him, nor can we debug.
Yeah it is kinda hopeless, but sometimes a paradigm shift can make things ‘click’ for someone stuck in a corner.
I read docs for glutPostRedisplay() and I used as ugluk said but still it was same as before.

I have used now glutPostRedisplay() in this but I am getting the still no animation in it.
If nothing is moving, then check if the variables controlling your animation are changing. If not, you have a bug somewhere, display the variables by debugging or by printing them out.
They are changing and also the program is taking keystrokes as I printing them on screen but there is no animation. I getting animation if use only GLUT_SINGLE
I just had a quick look over your code.
first off - why did you completely remove your init function?
Second - i cannot get anything to animate in single or double buffering.
your key presses are working and it is calling glPostRedisplay.
Your bug is elsewhere!
Dale
I simply put all the calls of init() in the main function.
I did not get your 2nd question.
What i am saying, is that with your current code, i cannot get your game to work with single or double buffering. it is not an issue with double buffering, but something else.
Im still trying it out. got to get on with my own stuff soon though!
Dale
see this one, I have commented glutPostRedisplay() and its with single buffer.

If your code is that long, post a link to it. Don’t just dump thousands of lines of code onto the forum. And especially don’t double space it. And even moreso, don’t do it twice.
Your main problem is your understanding of glFlush.
glFlush should be called once, at the end of your display function, like how glutSwapBuffers is used (use glFlush for single buffering, and glutSwapBuffers for double buffering).
by calling glFlush everytime you are drawing an object you are basically forcing all buffers to be drawn as quickly as possible by openGL.
how you are rendering your single buffering is to constantly empty the buffers after each object, and hence you are getting the animation when you should not be. (and the flickering of the objects)
When you have come to use double buffering, you have changed how openGL is flushing the scene to the screen, because double buffering essentially stores everything until the call to glutSwapBuffers is made, when everything is outputted to the screen (as opposed to how you are rendering your game, but NOT single buffering)
Basically, the flickering to begin with was caused by incorrect use of glFlush, this just didnt become apparent until you tried to use double buffering, which was completely the wrong thing to do, as you issue is not with double buffering.
your current single buffering state would look like this:
draw object
flush contents to screen
draw object
flush contents to screen
etc
hence the flickering effect which you can see. even in single buffering, you would not see this flickering as you should always be outputting all of your objects to the screen at the same time.
What you need to do is remove these glFlush calls, and replace them with a single glFlush call at the end of your display function.
Unfortunately for you, i have just tried this, which results in no animation in single buffering mode either, confirming my suspicions that this is not a double buffering issue.
The issue is solely on how you draw your scene to begin with.
Your game technically should not work in single or double buffering mode.
you can either:
continue to render the game incorrectly and put up with the flickering
sort out your drawing,variables and logic so that it works like any openGL application should!
I did with single glFlush there is no change
Did you actually read what i said?
The problem is not double buffering, it is the fact that you are constantly calling glFlush after drawing each object. This is giving the FALSE amination. This is what is causing your flickering to begin with, none of your objects should be flickering, not even with single buffering.
forget about double buffering entirely for a few minutes. It is having no effect on your application what so ever.
As i said above, i have tried changing your game back to single buffering, and how it should be done. this results in no animation in your scene because your functions in your display functions are wrong.
When you first reported the flickering problem, this is becuase of the recursive calls to glFlush. glFlush writes everything to the screen. You are constantly writing different objects the the sceen, which is causing the flickering problem. This would not even happen with single buffering if you were using it correctly, and the animation you are getting (currently) is a bi-product of your incorrect glFlush calls.
Like i said, you need to either put up with the flickering or solve the problem all together by rendering your objects correctly!
forget about double buffering, it is only confusing you and is NOT the solution to your flickering problem.
