I'm trying to run a slash command (/changeactionbar 1) when casting a spell.
It not be working.
I took the code from here http://us.battle.net/wow/en/forum/topic/3657445305.


Please halp.:<

I can't tell you if this is the most direct reason why it's not working (it may be due to a bug in RunSlashCmd or something--I didn't run that code nor do I really understand how it's supposed to work), but according to WoWPedia, ChangeActionBarPage() is protected when in combat. It stands to reason therefore that /changeactionbar is also protected in combat. Therefore attempting to run that command in a non-secure context won't work if you're in combat, which the events you're using suggest you are.

If the macro itself can change the action bar, can an addon running a macro through a slash command then also change the action bar or can't it?
I'm not that smart in these things.

[Dridzt]

It can but you need to utilize Secure Templates, either a SecureActionButtonTemplate if the actionbar swap is meant to happen on a click,
or a SecureStateHeaderTemplate if the swap is meant to happen on some condition (only conditions supported by the macro system are valid).

It's going to be a bit uphill for a new programmer as these while simple in concepts are not very beginner friendly constructs.

Edit: I should tell you upfront that some of the things you want to do are not possible (just looking at events).
You cannot take action through code when you're silenced or a cast succeeded or a cast failed etc.
That falls under automation and Blizzard has specifically disabled the ability for addons to make such decisions.
Only conditions supported by secure frames are these: Conditionals

Keep in mind that some slash commands are only usable with hardware events, i.e. a macro can only run if you use a key to activate it, otherwise people would make addons to run macro code for them, it does not work.

I am not sure about changing action bar, but it may require hardware event to work... or?

But what is the idea? To avoid the bar from changing when pushing SHIFT+2 and such?

[Jonisaurus]

Yes, it's obvious now that what I tried to do isn't possible.
I wanted to basically replace my stupid castsequence macro for Holy Fire / Smite with an addon that changes actionbars according to Holy Fire cooldown.

Unfortunately /castsequence doesn't allow spell queuing which is... ****.

As I'm short for keybindings and button space on my disc priest... is the /castsequence macro the ONLY way to combine the two abilities?

[SDPhantom]

I have a lot of macros on my chars that combine 2 or more spells in a macro, something modified to your use would be something like this:

#showtooltip Holy Fire
/cast [mod] Holy Fire; Smite

This casts Smite on an unmodified run and casts Holy Fire if a modifier is held. It also makes sure it keeps displaying the cooldown and tooltip info for Holy Fire.

Using it in Bartender so I dont need a macro just two keybindings, but thanks for trying to help

It's not so much that I can't watch out for the Holy Fire cooldown, it's more than I have to waste another keybind and a place for watching the CD on my UI for such a trivial task.

[Grimsin]

Just a side note, use of slash commands from LUA has been completely broken as of the latest patch and no version of RunSlashCmd will work properly.

[Nimhfree]

If you make a button that inherits from SecureActionButtonTemplate you can set attributes on it such as:

button:SetAttribute("alt-type1", "macro")
button:SetAttribute("macrotext", desiredMacroValue)

What this basically does is allows you to set a macro that will be executed when you alt-click the button. I use this in the addon Wholly to allow the addon to target a named NPC. The buttons get assigned their macro values dynamically.

This may allow you to get around using RunSlashCmd, but I have no idea whether the macros you want to use will be permitted.

[SDPhantom]

That'll be fine as long as you don't try to change anything while in combat, secure templates lock down and their attributes cannot be changed then. Only by a secure handler and that's another mess to go through that doesn't yield any differing result.
