One macro to heal all party members?

Can a macro be written so that Renew can be cast on all party members by clicking five times on same macro? First click cast on self, second click casts on next party member etc.
Also, can a macro like that be made to work even if group isn't always full?

I think so, haven't tested it but something like:

/Click button1,,,,
/Click ,button2,,,
/click ,,button3,,
/click ,,,button4,,,etc...

Button1: /cast [target=toon1] renew
Button2: /cast [target=toon2] renew

you get the idea

I'd go with /cast [@party1] renew instead of /cast [@toon1] renew. That way the macro should work whatever the group composition is.

Yes, this can be done with renew or if you like shield. Here is a link to a thread which shows how to do it and the last part works perfect.

Tried it, but it keeps casting on same character at every click...

Have you checked the link I poster, this is the code that works,
/castsequence [@party4] reset=5 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Renew
/castsequence [@party3] reset=5 ,,,,,,,,,,,,,,,,,,,,,,,,,,,Renew
/castsequence [@party2] reset=5 ,,,,,,,,,,,,,,,,,,,,,,,,Renew
/castsequence [@player] reset=5 ,,,,,,,,,,,,,,,,,,,,,Renew
/castsequence [@party1] reset=5 ,,,,,,,,,,,,,,,,,,Renew
/castsequence [@party4] reset=5 ,,,,,,,,,,,,,,,Power Word: Shield
/castsequence [@party3] reset=5 ,,,,,,,,,,,,Power Word: Shield
/castsequence [@party2] reset=5 ,,,,,,,,,Power Word: Shield
/castsequence [@player] reset=5 ,,,,,,Power Word: Shield
/castsequence [@party1] reset=5 ,,,Power Word: Shield
/castsequence [@party1] reset=5 Prayer of Mending

Yes, I tried this. It just keeps casting on myself.

/castsequence [@party4] reset=5 ,,,,renew
/castsequence [@party3] reset=5 ,,,renew
/castsequence [@party2] reset=5 ,,renew
/castsequence [@party1] reset=5 ,renew
/castsequence [@player] reset=5 renew

I thinkk...(think)
its because..


Needs to be on button 1 /castsequence [@party4] reset=5 ,,,,renew
Needs to be on button 2 /castsequence [@party3] reset=5 ,,,renew
Needs to be on button 3 /castsequence [@party2] reset=5 ,,renew
Needs to be on button 4 /castsequence [@party1] reset=5 ,renew
Needs to be on button 5 /castsequence [@player] reset=5 renew

right? each needs its own button because.. once first renewed is fulfilled the sequence resets...thus getting stuck on the first line?

yes, it is a click macro, so you need to assign a macro for each one and then use a main macro to reference it.

so to clarify, have your main (click) button have the following macro:

/Click MultibarRightButton1,,,,
/Click ,MultibarRightButton2,,,
/click ,,MultibarRightButton3,,
/click ,,,MultibarRightButton4,
etc....

Substitute "MultibarRightButton1" for another button location where you're putting your castsequences
To find out what a button is called use this macro:

/run DEFAULT_CHAT_FRAME:AddMessage(GetMouseFocus():GetN ame())

now your MultibarRightButton1 will have:

/cast [@party1] renew

MultibarRightButton2 will have:

/cast [@party2] renew

And so on

So when all is done, does this mean I will have five clickable macros (one for each) in my actionbar but I will be able to click only one of them to cycle through all macros?

Sorry if my questions are stupid but I'm quite new to making more advanced macros. :)

yes, you will have 5 macros and one of those will cycle through the other macros in the bar, you can substitute any spell you want in that cycle if you want to cast something different :)
