Chat/Movement conflict
A lot of people like to use WASD (or ZQSD for azerty layouts) instead of arrow keys to move. The problem you encounter is, when you're typing a message in the chatbox, you'll move around when hitting those keys. Same the other way around, if the chatbox is focussed and you'd like to move, you'll be spamming your chatbox with characters.
Now, there are a few possibilities for this issue:
1. When the chatbox is focussed, you cannot move with any key besides the arrow keys
2. After every message you submit, the chatbox is defocussed.
3. Leave it as it is now (the spammy, moving thing)
What do you guys think? If you've got a suggestion, feel free to post it.
Yeah, enter & space focus the chatbox in SVO while esc removes the focus. I'm not quite sure how this stuff is handled in other MMORPGs (can't remember).
1+2 is usually a good way to go, except let arrow keys be used for controlling the cursor in the textbox. Assign a button (like esc) that will let you instantly unfocus the textbox without sending/clearing the contents so people don't get "death by typing". Also, you can make it so pressing enter while the game screen is focused puts the focus into the chat box.
