This will work.
A better solution would be to simply initialize the cvar before
keyvalues gets called.
If you stick it in CFubar's constructor, that should do the trick.
CFubar::CFubar() {
CVAR_SET_FLOAT("oz_defaultctf", 0);
}
Now its up to KeyValue() to change it to something different.

This won't work. If the KeyValue function is called again after the
defaultctf
key comes through, then the cvar will be reset to zero and the actual
value
will be lost. What you need to do is have a flag:
int fResetDefaultCTF = false;
void CFubar::KeyValue (..etc..)
{
if (!fResetDefaultCTF)
{
// defaultctf cvar has not been reset
CVAR_SET_FLOAT("oz_defaultctf", 0);
fResetDefaultCTF = true;
}
// blah...
// normal code to check keyvalues including defaultctf keyvalue
}
Then the cvar will only be reset once. You need to reset the flag back
to
false after all the keyvalues have been sent, a good place to do this is
the
Spawn function of the same entity. (Spawn is always called _after_ all
the
keyvalues have been sent to the KeyValue function.)
