KEY BUTTONS
|
|
|
|
Continuous button event tracking is complicated by the fact that two different
|
|
input sources (say, mouse button 1 and the control key) can both press the
|
|
same button, but the button should only be released when both of the
|
|
pressing key have been released.
|
|
|
|
When a key event issues a button command (+forward, +attack, etc), it appends
|
|
its key number as a parameter to the command so it can be matched up with
|
|
the release.
|
|
|
|
state bit 0 is the current state of the key
|
|
state bit 1 is edge triggered on the up to down transition
|
|
state bit 2 is edge triggered on the down to up transition
|
