Using %modifiers with the onMousedown function

#1 Make sure you are testing against bits. For example, Left Shift is 1, shifted left 0 times (thus "Bit 0"). That's why it is 1. Right Shift is 2, left control is 4, etc. Often, you'll see code like this:

if( (%modifiers & $EventModifier::LSHIFT) ||
    (%modifiers & $EventModifier::LCTRL) )
{
  ... code when left shift or left control is pressed.
}

There are "shortcuts" added to the system. For example, if you don't care which shift, you could write

if( (%modifiers & $EventModifier::LSHIFT) ||
    (%modifiers & $EventModifier::RSHIFT) )
{
  ...
}

// or... even smaller

if( (%modifiers & $EventModifier::SHIFT) )
{
  ...
}

Hope that helps clear it up!

#2 Also, to be complete:

Global Script Varaible    Code Constant  Value
----------------------    -------------  -------------------------
$EventModifier::LSHIFT    SI_LSHIFT      (1<<0) = 1
$EventModifier::RSHIFT    SI_RSHIFT      (1<<1) = 2
$EventModifier::SHIFT     SI_SHIFT       (SI_LSHIFT|SI_RSHIFT) = 3
$EventModifier::LCTRL     SI_LCTRL       (1<<2) = 4
$EventModifier::RCTRL     SI_RCTRL       (1<<3) = 8
$EventModifier::CTRL      SI_CTRL        (SI_LCTRL|SI_RCTRL) = 12
$EventModifier::LALT      SI_LALT        (1<<4) = 16
$EventModifier::RALT      SI_RALT        (1<<5) = 32
$EventModifier::ALT       SI_ALT         (SI_LALT|SI_RALT) = 48

#3 That does help thanks! The way I was echoing to the console I was only ever getting 1. Which had me suspecting that I wasn't doing it right. Cheers William.
