hi,
I would like to know if it’s possible to take care of two “key down”.
For example the user presses the key for “fire” and the key for “move down”.

Can I check these condition?
tnx

I usually store the keydown in a specific bool value.
If another keydown follows which is modified by the first one, then you can check the boolean value.
But I don’t think that this sdl function is thread save, but I’m not sure!
Hope this helps.

Hi Christian,
I didn’t find your game sources.

Are you sure that we can’t use a &-Logic somewhere?

Yes, check out SDL_GetKeyState()
Most keyboards have hardware limitations on the number of keys that can
be pressed simultaneously., but usually all of the arrow keys can be pressed
at once.
