Working with key events

[Arkan]

First time I'm working with key events, I'd like to know these questions...

1. Is there a function like GetPressedKey()? I couldn't find any...

2. Assuming 1. doesn't exist, would this be a good work-around (it would be MPI right?)?

function Scroll_in_inventory_con takes nothing returns boolean
    return true
endfunction

function Scroll_Actions takes integer key returns nothing
    //actions
endfunction

function Scroll_Left takes nothing returns nothing
    call Scroll_Actions(0)
endfunction
function Scroll_Right takes nothing returns nothing
    call Scroll_Actions(1)
endfunction
function Scroll_Down takes nothing returns nothing
    call Scroll_Actions(2)
endfunction
function Scroll_Up takes nothing returns nothing
    call Scroll_Actions(3)
endfunction

//===========================================================================
function InitTrig_ItemScroll takes nothing returns nothing
    local integer i = 0
    local trigger t1 = CreateTrigger()
    local trigger t2 = CreateTrigger()
    local trigger t3 = CreateTrigger()
    local trigger t4 = CreateTrigger()
    loop
        exitwhen i>LastPlayerIndex
        call TriggerRegisterPlayerEvent(t1,Player(i), EVENT_PLAYER_ARROW_LEFT_DOWN)
        call TriggerRegisterPlayerEvent(t2,Player(i), EVENT_PLAYER_ARROW_RIGHT_DOWN)
        call TriggerRegisterPlayerEvent(t3,Player(i), EVENT_PLAYER_ARROW_DOWN_DOWN)
        call TriggerRegisterPlayerEvent(t4,Player(i), EVENT_PLAYER_ARROW_UP_DOWN)
        set i=i+1
    endloop
    call TriggerAddCondition(t1,Condition(function Scroll_in_inventory_con))
    call TriggerAddCondition(t2,Condition(function Scroll_in_inventory_con))
    call TriggerAddCondition(t3,Condition(function Scroll_in_inventory_con))
    call TriggerAddCondition(t4,Condition(function Scroll_in_inventory_con))
    call TriggerAddAction(t1, function Scroll_Left )
    call TriggerAddAction(t2, function Scroll_Right )
    call TriggerAddAction(t3, function Scroll_Down )
    call TriggerAddAction(t4, function Scroll_Up )
endfunction

Forgot I need to pass player index aswell.

1. Not quite, but see below.
2. Sort of, yeah, but you can also use GetTriggerEventId() which should return EVENT_PLAYER_ARROW_LEFT_DOWN, EVENT_PLAYER_ARROW_RIGHT_DOWN, EVENT_PLAYER_ARROW_DOWN_DOWN or EVENT_PLAYER_ARROW_UP_DOWN depending on the event which triggered, assuming you have all four registered for the same trigger.

Ah yes, that works and looks better aswell. Thanks.
