Able Ability System Info and Support Thread

[ExtraLifeMatt]

Hello,

Could you somehow "pin" the default ability so that it shows up first when we create a new ability? Once we have a decent amount I see the designers getting a bit confused. Or maybe add the option to blacklist abilities from showing up on that list? That way I can only have "AblAbility", "BasicMeleeAttack", etc. there. Thanks!

Yea, I can toss it at the top or toss in some option to hide inherited classes. It confuses me too every time, so I've been meaning to change it.

I was able to run the .bat files, but can't find the .sln file.

The UE4.sln should be in the same directory you ran "GenerateProjectFiles.bat". You might want to go on YouTube and just search "Build UE4 source" as I bet someone has a good video tutorial for this.

Yes. Any chance you can add OnAbilityStarted / Ended / Interupted virtual voids to AblAbility.h? Basically you have events for BP but nothing for C++.

That was added for the AbilityComponent, but not the Ability itself. I see. Yea, I can see about adding that. I'm not sure it'll be 1:1 with the BP side (since BP nativization is pretty decent, it gets compiled to C++ anyway so I didn't have any huge performance concerns) - but I can see the appeal of having some of the larger hooks having a C++ counterpart.

You should be doing this:
1.) Download the latest version of the engine source from Git ( https://github.com/EpicGames/UnrealEngine/releases ). If you can't view that page, you need to follow the instructions here: https://www.unrealengine.com/en-US/ue4-on-github
2.) Unzip the file to some directory on your computer.
3.) Run Setup.bat
4.) Run GenerateProjectFiles.bat
5.) Open up the UE4.sln file in Visual Studio, then you can navigate to that BlueprintUtils file, make the change, and build the Solution.

Can you elaborate? You mean Dynamic Montage blending?

Hope next update will be focused more on C++ than BP.

Next update is just a few tweaks and stuff, as well as 4.19 support. No new features. Was there something specifically you were looking for?

Able just notified me on an update in the engine. Did you update it or is it nothing?

I didn't push any update, so I'm not sure what that would be. v2.15 is the latest (next update will go out when 4.19 is released).

Sorry for the delayed response to any emails, it's been a hectic week.

You can call abilities in C++ simply by getting the actor's AblAbilityComponent and calling "ActivateAbility". You need to create a context (there's just a static method in FAblAbilityContext called "MakeContext" that will do that for you), and then just pass it in.

Should be pretty straight forward.

Yeah that sounds fine, thanks!

Greetings,

How do I call abilities in C++? Sorry if this has been asked before, but I tried finding C++ documentation and it was empty.

P.S: I have sent you a couple of emails so if you could read those that'd be great

The problem with the official tutorials is that it assumes I have a background in coding. The first step is to find the root directory and run GenerateProjectFiles.bat, but it's not in any of the UE folders I've looked at.

Did you follow the Downloading Unreal Engine steps first?

1.) Download the latest version of the engine source from Git ( https://github.com/EpicGames/UnrealEngine/releases ). If you can't view that page, you need to follow the instructions here: https://www.unrealengine.com/en-US/ue4-on-github

5.) Open up the UE4.sln file in Visual Studio, then you can navigate to that BlueprintUtils file, make the change, and build the Solution.

Running a custom version of the engine isn't terribly simple, but it's do-able. If this seems like too much, I would suggest just not using the "Play Session" until I can work a fix out with the Epic guys.
