Hey, I wanted to know if forcing PvP in an area made your players deal friendly fire damage to each other in TLA.   

I know!  I think so, too!   

I'm sure it will cause lots of griefing, but it can also be very exciting.

Forcing pvp will cause players to hurt eachother, but I think it would also prevent beneficiary spells to work on other players, so you would not be able to heal anyone else than yourself and your pet or minions, for instance.

Edit: PvP will also cause pets to attack other players.

Aargh! Not the easy fix I was hoping for.

Yes, this is for LoE.  You're probably right Phanjam.

I tried for about 4 hours to get friendly fire to work with normal weapon swings without any luck.  It might be better anyway to just limit friendly fire to skills.

You can add a hidden affix. This affix can cause damage only to friendly targets.
I mean any weapon procs. Something like bleeding or stun.

That's a good point.  It doesn't have to be full damage to your allies with weapon effects et al.

Does anyone know if there's an elegant way to implement friendly fire on skills by say, flipping one variable?  Or do I have to give each skill separate affixes for Enemy/Self/Allies?

make the damage shape the skill itself and the affix target: everybody

this should work,
you could also go into the event itself and put
<BOOL>IGNOREALIGNMENTTYPE:1
this will make the event ignore the target setting you put into the skill

Hahahahahahaha!     I just spent the past 10 minutes lighting my pet badger on fire.

Okay, so, the above is mostly correct, but I didn't want this skill in particular to set the caster aflame, so a few adjustments were needed.  Setting 'Everybody' on an Affix seems to target the caster as well, even if they're not hit by the damage shape.  Dunno why.  But, here's how I got it to work correctly:

Set 'EVERYBODY' as the Target of the Skill.
Set 'ALL' as the damage shape's target.
Set 2 affixes, each identical save that one targets ENEMY one targets FRIEND.

Voila.

Nah, it's not an EVENT_START.

I'm not sure why, but, as affix target types, EVERYBODY and SELF affect the caster whether or not the caster is hit by the damage shape.  For now, I guess self-inflicted damage is off the table unless someone can figure it out.  I may try later.
