How to autofire F in Autohotkey?

I tried a different approach with the "automatic shooting" function that JoyToKey offers, but the problem seems to be in Psychonauts itself. While it does register keys remapped through JoyToKey, it does not accept repeated inputs without registering a release of the button you pressed.

This led me to the idea to send raw input events, which works. In this AHK example I just assigned the hotkey CTRL-r to make Raz jump 20 times.

^r::
Loop 20
{
    Send {Space down}
    Sleep 10
    Send {Space up}
    Sleep 1000
}
return

Should work with any other key as well.

I finally got it to work

loop
{
^#f::
If getkeystate("f")
    send {f up}
else
    loop
        {
        send {f down}
        sleep 20
        send {f up}
        sleep 20
        if getkeystate("f")
            break
        }
return
}

I have the Mac version of Psychonauts, so I used Sikuli as the scripting engine, which works on both Windows and Mac. Sikuli uses Python as its scripting language.

This script presses F every 0.12 seconds until either 30 seconds has passed or you stop the script with ⇧⌘C. You can configure it by changing the values of the constants at the top.

# Psychonauts: repeat F to collect deep arrowheads

APP_NAME = "Psychonauts"
KEY_TO_MASH = "f"
TIME_TO_RUN = 30*1 + 00
TIME_OF_PRESS = 0.02
TIME_OF_WAIT = 0.10

def holdKeyForTime(key, time):
    keyDown(key)
    wait(time)
    keyUp(key)

def mainAction():
    time_to_run = TIME_TO_RUN
    time_of_press = TIME_OF_PRESS
    time_of_wait = TIME_OF_WAIT
    time_per_press = time_of_press + time_of_wait
    num_presses = time_to_run / time_per_press

    for i in range(num_presses):
        holdKeyForTime(KEY_TO_MASH, time_of_press)
        wait(time_of_wait)

App.focus(APP_NAME); wait(1)
mainAction()
