Kb.eat() usage
Hi there,
From what I understood from the header is that the eat() method can be used to "disable" keyboard usage in other functionality: it should disable, for example, the movement keys from my character as 'it's a different code'.
Code:
virtual void update(C GuiPC &gpc)
{
super.update(gpc);
if(Gui.kb()==this)
{
if(Kb.bp(KB_ENTER))
{
Kb.eat(KB_ENTER);
Str t=T();
t.clip(pnconstants::MaxChatLength);
if(t != "" || t != " ")
{
Chat.New(ChrData.name+": "+t);
ClientSendChat(Server, t); hide();
}
}
}else
{
hide();
if(Kb.bp(KB_ENTER))
{
Kb.eat(KB_ENTER); clear().activate();
}
}
}
However, it doesn't seem to work no matter where I place it. Did I perhaps misunderstand the header information? How can I disable other functionality by keyboard input as soon as the TextLine is being used to type a message?

RE: Kb.eat() usage
I believe that Kb eat is only for the one update loop, so be weary of where the kb eat is called as anything on that update loop before will still be able to use it and the next update it will be free to be called again

RE: Kb.eat() usage
Then a workaround would be to create a boolean that will disable user input in the player update function where keystrokes are checked if any textline is active. Easy to do, but I still wonder how we would use eat() in this case.... just curious

RE: Kb.eat() usage
Kb.eat will only clear pushed released Kb.bp and Kb.rs etc states. But it does not clear Kb.b state.
But for continuous movement you should better check that when processing the character movement.
Example:
If(!Gui.kb() || Gui.kb().type()!=GO_TEXTLINE)processCharacterMovement();
That's a simple example

RE: Kb.eat() usage
That deffinitely helps in understanding what kb eat does! The example you provided I implemented and all works as it should right now 
Thanks for explanation, Greg!
