Sorry it took this long. I saw Crazyduck's message but completely forgot about it...
There was indeed a problem with the ApplyChance, it was working the wrong way around i.e. 100 meant it never applies. It should now be fixed.

I have a similar problem as Crazyduck. I cannot activate the abilities themselves but everything else works. I don't have any error messages in my logs. I posted my config in the discussion. Maybe someone could take a look at it and help me.

Maybe someone can help me with this. I created some dark events, they do appear in game, have proper localisation etc. However when activated they fail to apply abilities themselves, I checked the log.

For example Sectoid dark event:

+AbilityDarkEvents=( DarkEventID = "Premonition", \\
Abilities[0] = (AbilityName="Shadowstep", ApplyToWeaponSlot=eInvSlot_Unknown), \\
Img = "img:///UILibrary_MPCards.MPcard_Sectoid", \\
AffectedUnits[0] = "Sectoid", \\
bInfiniteDuration=true,\\
ApplyChance=100,\\
MinFL = 8 \\
)

And that what launch log says:
...
[0016.52] AbilityDarkEvents: Created GrantDarkEventAbility_Premonition
...
[0017.18] AbilityDarkEvents: Created AbilityDarkEvent_Premonition
...
[0082.73] AbilityDarkEvents: Not Affected Sectoid
[0082.73] AbilityDarkEvents: Failed apply chance Shadowstep

What can be the reason for that?

Thanks to h4ilst0rm you need no programming skills at all. I can't write a single line of code, but still i could make almost a hundred new dark events. H4ailst0rm provided us here with all the coding stuff done allready

As cool as the idea of creating my own dark events sounds, I'm not a programmer, so this well beyond my level of capabilities

ApplyChance = 60 means every soldier has a 60% chance to get it, so its entirely possible to get it on all soldiers or on no-one

I don't if this is still being worked on, but I'm running into a problem with a dark event I made. I made a DE where all XCOM soldiers get the Chosen's high ground weakness. When I launch a mission, some people have the icon and the weakness applies, but it's completely random who gets it. One squad everyone has the weakness. Then next mission nobody does.

+AbilityDarkEvents=( DarkEventID = "DE_XCOM_HeightWeakness", \\
Abilities[0] = (AbilityName="SoftHead"), \\
Abilities[1] = (AbilityName="ChosenGroundling"), \\
Img = "img:///UILibrary_StrategyImages_SF.TECH_Experimental_Rounds", \\
AffectedUnits[0] = "Soldier", \\
ApplyChance = 60, \\
MinFL = 1 \\
)

Could there be a time in the future where the config allows to make "groups" of enemies similar to Advent not created equal?

@kitsune. thank you. very well. I did not know that users can do this. I am looking for more dark events like "alien side goals" which is not compatible with COVERT Infiltration. But every additional dark event is more than welcomed!

@Skarsatai 2.0
I put one up for people to use.

I believe anyone should be able to start a discussion for that sort of thing.
If someone wants to publish pre-made configuration as a mod its not only allowed but encouraged.

Hi H4ilst0rm. Great mod. Can you open a discussion section here so that users can post their Dark events and Ideas to publish to others ?

Good idea, added in the option to add multiple abilities per DE. Any abilities should work given that you put in the correct Template name.

I was just wondering. Can you put more than 1 ability in a dark event? Also, if I make a custom ability with something like this mod can I put that into a dark event?

Thank you so much for this. Looking forward to trying it out next campaign
