Lua key press redirect

David (if your watching )

I'm trying to be clever and redirect a key press. The following script is meant to intercept the press of the play button and turn this into a half shutter press. But it doesn't seem to work. The play button responds as if play was pressed. Any ideas where I'm going wrong in this test script?

Code Select Expand

test_menu = menu.new
{
    name = "Show keypress",
    choices = { "Off", "On" },
    value = "On",
}

function event.keypress(key)
    if key == KEY.PLAY and test_menu.value == "On" then
key = UNPRESS_HALFSHUTTER
return true
end
end

Function parameters are "pass by value". Setting them will have no effect on the caller.

Thanks. BTW is the custom_picture_taking (arg) functionality working in the Lua event module?

If so how do I use this within a Lua script?

Finally, I assume this is the correct use of the press function in the Lua key module?

Code Select Expand

key.press(HALFSUTTER)

Cheers
