Bad Events

[Pol]

Hmm.. when I press Tilde or Numpad keys, they register as an event with Event.Type == Event.KeyPressed but their Key.Code == 0 ?

No matter which numpad I press, tab also.. all == 0 ?

This seems similar to a fault with GLUT I used to encounter.. basically, GLUT didn't register a keypress for numpad keys at all. At least SFML registers them but they are 0.. any idea why?

[Pol]

Further note... if I have NumLk enabled then it registers the numpad keys, otherwise it doesn't. (Tilde always return 0)

[Laurent]

What OS? Which version of SFML?

Debian & 1.5

Basically, I hit the following keys in the following order (on the Numpad, plus Tilde and Num_lock):

Tilde,0,1,2,3,4,5,6,7,8,9,Num_lock,Tilde,0,1,2,3,4,5,6,7,8,9

Say if you need more info.

Also, I noticed there's no SFML Key definition for Num_Lock.

Thanks for these useful informations, I'll see if I can patch the code with it
