i start getting this error after LOTV came out, sometimes when i use target point abilities with LM effects, I'm getting this error, anyone knows what wrong with that?

I think this is just a thing that has been happening before but now they just added Error message to it when it happens. Don't think it has any significant impact on anything.

but what I did wrong? I don't like these gazillion error messages

i realized that this happens mostly with abilities that uses launch missile effect with create unit effect on the impact

Launch or target offset Z for the missile unit (not actor) is below the ground. Setting it to 0.5 or 1 is a good idea.

but then they will explode in air

@uroboros1987: Go

Go to Map Options, there is an option to allow or disallow targeting below base height of the map. I think it got defaulted to on. It was added with Void.

@ArcaneDurandel: Go

funny i changed thiss option and now I'm getting an errors each time i launch missile =)

I've got this error message too. It happens to an ability that targeting point and launching missile. I tried tinkering with site operations of the attack actor - no success. I remembered that Tychus launches grenade, and went to see how is it implemented. But found out that Tychus toss grenade attack from the campaign throws this error too. I also checked infestor's infested terran launch actor, but it targets created unit, and there's no error. I don't want to create a dummy unit as a target, I want to find a solution for the pure targeting point situation.

1. Does anyone know how to launch a missile to the ground and not get this error?

2. Can anyone name some unit, maybe from later campaigns, which launches a missile to the ground. Maybe they implemented it differently in later expansions and there's solution somwhere.

@Zolden: Go

Ravager's ability it's a missile targeting the ground. I don't really know if that's what you seeking but it's the first thing that comes to my mind when you speak about "missile targeting the ground".
EDIT: I remember having done things like this when I used to map-making. Another example is one of the Archangel abilties from Heart of the Swarm.

@TheSC2Maniac: Go

Thanks, tried Archangel. Guess what. Subj.

It looks like system determines impact point height as 7.9998 due to fixed value imprecision. So, everything probably works ok. But feels like if we use some site operation with a little height offset, it will work as intended. I tried all I thought may work - different site operations or other actor tinkering. But nothing worked ;/

New flag from patch 3.0.0 "Validate Benign" causing this warning to pop up. Go to your launch missile effect and uncheck it.

@abvdzh: Go

Thanks, but It didn't help. Though you gave me idea to refocus from attack actor to launch effect, and I found solution. Setting little Z offset in the Target Impact Offset field removes the error.

Thanks, but It didn't help.

how's that? i tested it with tychus grenade toss and it worked flawlessly. Try to set impact point site operation (in action actor) to SOpShadow too. It must work......... -_-

edit:

hm, it is weird i did it again and now it doesn't work, wtf.....

edit 2: Ok man i realy don't know what is this trash :D but it's working only with LotV campaign dependencies. If you using WoL campaign dependencies it does not work. Seems that it is some conflict connected with an abscense of this property (Validate Benign flag) of Launch Missile effect in WoL build.... i dunno.

With LotV dependencies on that shit works!

@abvdzh: Go

Setting impact point site operation to SOpShadow doesn't fix it either, but also it causes the missile to fly under caster's feet instead of aimed target. I think editor performing its revenge to me for shitting on it by moving to unity.

Check what i added above. It is issue with old WOL dependencies. Buy LotV or gtfo :DDD

added proof of evidence:

Wow... What a chest of wonderful mysteries and miracles this editor of yours. Thanks dude, you're great editor detective.

I have LotV, but prefer to work with WoL dependencies for faster data browsing.

well after a few minutes of tinkering again i don't even know what exactly causing a bug. Maybe old terrain mesh itself? we'll never know :X.

There's slight randomness in this problem, based on the imprecision of fixed number. When terrain height is 8, it's being rounded to 7.9997, which is < 8, and the problem emerges. I can imagine a situation where terrain height is 7.9, and it's rounded to something like 7.9002, and error wouldn't happen.
