 Posted: Mon Oct 02, 2006 2:59 pm Post subject: Text input request |
 |
|
In FreeUniverse, we sometimes want the player to enter text, however this doesn't cut it:
| Code: | arc.io.input.process();
if(arc.io.input.charHit)
{
// add arc.io.input.lastChar to string
}
|
It does not work, since it is possible that two keys are pressed between two calls to process() and we'd only get the last one of the two. Also, if a key is pressed and released before process() is called, charHit will be false. (this could be intentional, but from the docs I expected charHit to mean: the user hit a character between two calls to process)
To remedy this, we have to scan through the whole symbol range with arc.io.input.keyHit(...) to check which characters have been hit and know nothing about the order of keypresses. Is there any way to accomplish this?
It would be helpful if lastChar was the array of characters that have been hit between two calls to process(), maybe with a better name (but I've no good idea myself).
If you agree with this change, I can do it myself (SVN access required) or send you a patch. |

| Hey I pretty much have a GUI done here ( http://www.dsource.org/projects/arcgames/browser/trunk/arc/gui ) , I'm not 100? sure on what problem you are having, but I've got a 'textfield' to work fine so if you want you could just have me finish and implement the GUI into freeuniverse. |

Characters of the typed text are missing. Check the FreeUniverse loading screen for it. If you type fast, some characters will be dropped, for the reasons described in the first post. (conceptually, the problem should be platform-independent. I only tested it in Linux)
I will look at your text-input code though. |

| Oh alright, you can make the changes to arc in the freeuniverse SVN, that is where I'm going to be developing Arc for a while (because I am developing it to cater to freeuniverse). |

| Okay. Were you able to reproduce the bug, though? |

I think I know what you are talking about, a while back I was wondering why my text wasn't so responsive 
but with a faster computer now it is hard to tell. you can make the change, or ask me to do it, I don't mind. |

Okay, I'll make the changes then.

It has been fixed. lastChar renamed to lastChars. |
