Binding a spell @cursor

I would like to do "alt click" and it to drop D&D where the cursor is, no questions asked. I can do "SetBindings("ALT-BUTTON1", "SPELL Death and Decay") but it's missing the "@cursor". The way around it I can see is to do "SetBindings("ALT-BUTTON1", "MACRO DeathAndDecay")" where the macro does "/cast [@cursor] Death and Decay".

Is there a better way of doing this so that I can skip the macro?

IN ADDITION:

I have a number of key bindings to macros where my addon code sets up the key bindings in LUA, this ties a key press to a macro, and the macro calls back the addon via the /command system. A bit of round about way. Can I instead bind a key to execute some LUA code directly and to avoid having to set up macros which are stored and maintained externally to my addon ?

I think you could try something along these lines

Code:

local button = CreateFrame(

  "Button", "NameThisButton", nil, "SecureActionButtonTemplate"

)

button:SetAttribute("type", "macro")

button:SetAttribute("macrotext", "/cast [@cursor] Death and Decay")

and then

Code:

SetBindingClick("ALT-BUTTON1", "NameThisButton")

As for your second question, you can listen to all key presses like this, but you can't run any protected code in the handler.

Code:

local MODS = {

  SHIFT = IsShiftKeyDown,

  ALT = IsAltKeyDown,

  CTRL = IsControlKeyDown,

}



local MODS_SEPARATE = {

  LSHIFT = IsLeftShiftKeyDown,

  LALT = IsLeftAltKeyDown,

  LCTRL = IsLeftControlKeyDown,



  RSHIFT = IsRightShiftKeyDown,

  RALT = IsRightAltKeyDown,

  RCTRL = IsRightControlKeyDown,

}



local frame = CreateFrame("Frame", nil, UIParent)

frame:EnableKeyboard(true)

frame:SetPropagateKeyboardInput(true)

frame:SetFrameStrata("DIALOG")



local function getMods(checks)

  local mods = ""



  for mod, isDown in pairs(checks) do

    if isDown() then

      mods = mods .. mod .. "-"

    end

  end



  return mods

end



frame:SetScript("OnKeyDown", function (_self, key)

  if MODS[key] or MODS_SEPARATE[key] then

    return

  end



  print(getMods(MODS_SEPARATE) .. key)

end)

Note that you could also listen for MODIFIER_STATE_CHANGED and cache the states. However, alt-tabbing can mess this up as the event will only fire for one state but not the other.

OK thanks. The first example allows me to set up a macro from the addon, without using the WoW client. This is good, if it means I do not have to litter the WoW client with macros.

The second example, I believe, allows me to listen to keystrokes but I am not sure why I would want to listen to raw keystrokes - maybe this allows me to run ANY code at all without even using a macro attached to a button ?

The second example is how to have an addon run its own code when a key is pressed. It won't let you do protected actions like use an ability. You have to still mess around with the keybind system and SecureActionButton templates.

Thank you. I have not had time to analyse the second part yet, as I am still trying to find my way around the best way to do what I want to do.
