Ability/Attribute Modifier Bug?

[dreycoon]

I have an ability that costs 30 stamina that I want to have run for 0.5s always so I have it setup like below


The problem looks like when CanStartAbilityInternal runs and passes, the stamina gets subtracted


but then Update runs right after and it checks the stamina level again but if it is not above 30, then the ability stops. So the ability starts and stops immediately.


Is this a bug? It only happens if the remaining stamina is not above 30 after the ability activates.

Where do you see CanStartAbilityInternal subtracting the amount? I just see an IsValid check which does not modify the value:

if (m_AttributeModifier != null && !m_AttributeModifier.IsValid()) { return false; }

The subtraction amount happens here which is called on AbilityStarted.


The bug happens because Update is ran before the stop time has elapsed on the ability and checks the attribute level too soon

Ah, I see. Ok, thanks for the report. I'll take a look at this for the next update.
