How do i make this macro?

[RakeRipGG 0]

I want it to use flash of light on the mouseover target but if the mouseover target cant be healed (like an enemy) i want it to do nothing (by default you heal yourself).

Thank you.

#showtooltip Purify Spirit
/cast [@mouseover,help][@target,help][@targettarget,help][]Purify Spirit

This'll do what you want and more, just replace Healing Wave with any helpful direct healing/dispel spell you want and it will select it's target based on the following priority:
1) Mouseover target, be it the avatar or raid/party healthbar.
2) Your target if friendly
3) The target of your target, if you're targeting an enemy who is targeting a friendly
4) Yourself.

Edited: I'll test when I get home from work and update this.

Then just modify it and delete the things you don't need:

#showtooltip Flash of Light
/cast [@mouseover,help][]Flash of Light

Strange. Works perfectly fine for me according to what you asked for in first post. I use that exact macro myself.

#showtooltip flash of light
/cast [@mouseover,help,nodead]flash of light

That should do what you asked for.
