I mean for a pong game.

Ah lol, I'm getting old! All this new stuff...

Hi!

Noticed your flag

PANEL* panDisplay ={ flags = VISIBLE;}

should be

PANEL* panDisplay ={ flags |= VISIBLE;}

Hope this helps

can someone please answer my question?

Hi!

Sorry SpacXscape to "but in" but a question on flags as come up
because of this comment that I made and I would like to
clear up the facts

Are you saying that flags = VISIBLE is used inside the panel def.
and that or (my.flags |= VISIBLE;) is used only outside?
I've got to read on this again.
If this is the case I have a lot of corrections to do.

If you set a flag with "=", you will reset all other flags that where set before. This is normally not what you want, but it is when you are defining the panel. When defining a panel, there are no other flags set yet (you can be sure of that), so you can use "=".

Normally when you define a new variable it will have random content if you don't initialize it. If that where the case for the "flags" parameter, setting the flag with "|=" would be harmful because you MUST overwrite the content of flags. But I don't think flags contains random content becuase if you omit the flags parameter, all flags will be 0. So if I'm right, you can set it with both = and |=. Nevertheless, = is still clearer because |= indicates that other flags might have been set before (which is never the case in a panel definition.)

HI Excessus!

I like this explanation. (I've copied it)
I've done a bit of cleaning and it's not to bad.
I had most of them right.

Now I hope that SpaceXcape will find the models that he was looking for.
