Script for GMS

[Safrock]

Hi, im trying a script for GMS(Global maplestory)

Spoiler

WinWait, MapleStory,
IfWinNotActive, MapleStory, , WinActivate, MapleStory,
WinWaitActive, MapleStory,
C::
Loop
{
Send, {SPACE down}
Sleep, 3000
Send, {SPACE up}
Send, x
Sleep, 500
Send, {SPACE down}
Sleep, 3000
Send, {SPACE up}
Send {DOWN down}
Sleep 500
Send {ALT}
Send {DOWN up]
Sleep 500
Sleep 2000
}

The point is that it does not work the way I want to do it (Due to my poor programming skills.)
The sequence should be:

>Press space for 3 or 4 seconds.

>Press X, and wait like 0.5 or 1 sec.

>Hold the 'Down' key and simultaneously press the ALT key (for the character descends from one platform to another)

>Press space for 3 or 4 seconds.

And repeat all this actions for about 15 minutes.
