@ExtraLifeMatt , last time i used able it was pretty stable ( no pun intendend). Now i can´t even play the ability. I hit play - nothing happens. The UI also feels worse than before. But my main question is, when can i use able for my projects? I tested the 4.22 one, perhaps it was too early ? Are you trying on fixing the custom task recompiling issues soon ?

@ExtraLifeMatt The new new ABLE is runing under what engine versions? I’ve seen it in this threat however I cant find it. Do you guys have a dsicord channel?

I got the crash again while working on my project. This is seen at the end of the crash report text file:
Can’t find file ‘/Script/AbleEditor’
Can’t find file for asset ‘/Script/AbleEditor’ while loading NULL.

I followed an old solution you posted by adding

// Purge any NULL graphs
FBlueprintEditorUtils::PurgeNullGraphs(Blueprint);

In the specified location, but no luck.

I have the same troubles that you when trying to disable camera and collision cylinder, etc;
About the tracing targets…you need to enable this in timeline menu and make sure that tracing query are running one the client too. Only on server don’t show it.

Check your output log. Are you sure your character has an Ability Component? The times when I’ve seen an ability not play it’s because of one of two issues: 1.) You have a channeling condition which isn’t valid when you preview (i.e. some key press), or 2.) You don’t have an Ability Component and adding one dynamically is not working well (for whatever reason, still debugging that one).

Also Custom Task compilation should be fixed as it’s passing my local testing. If it’s not, please give me a repro or you can upload a sample project that shows the issue here: Dropbox - Submit files

Able always works for the latest 3 versions, so 4.20, 4.21, 4.22. I can’t support older versions unfortunately. There is a player discord channel (I believe I link to it in the first post), but I’m not normally on there. Here is the best place to reach me.

You can try something. Open up Able.uplugin and set the LoadingPhase for AbleEditor to “PreDefault”. That’s fixed that error before, but it causes some other issues with Able Editor Settings not being able to find game classes (since it loads things pre-game binary). But, if that fixes things then I’ll find a work around for the other.

Clicking the Show Collision / Show Camera options in the view drop down in the Ability Editor isn’t hiding those? That code hasn’t changed so I’m a bit shocked it’s broken.

Yup this fixed it! Thanks so much.

Fun. Okay, then I’ll find a way to fix the Able Editor Settings. If you see null classes in your allowed classes drop down, that’s why.

EDIT: Testing a workaround for the config issue, and found the issue with camera/character collision not respecting the options. Fixes incoming.

No. When I go on Ability Editor, click in TIMELINE menu and clicking in this checkbox…don’t change nothing in my preview scene.

Other issue that I see is: When select an animation task and try to change the animation…this don’t change…need to delete the task and add this again with the right animation.

Yea, I found the issue with the checkbox for Camera/ Collision. I have a fix coming.

As long as you save the Ability (which happens automatically when you try to play an Ability), it should change the Animation during the preview. I’ll check that locally as well, but I’d look at your log for any weird errors.

Hi matt, Just installed on UE4 .22 and When i opened ABLE this crashed UE4 with error

How I can make hit reactions??? Like frontal hit, back hit, left and right hit…

That is up to you. Able doesn’t support that out of the box.

I would do it where I figure out the general direction of the damage (so, just create a vector from the damage source to my actor). And then do a handful of half space tests to find the general location.

Task to MoveTo, jump etc don’t work…

Hey,
I recently started working on my project again and saw that there was an Update for Able.
Right now it seems that the “OnGetDynamicProperty_Cooldown” function isn’t even called.
All I did was copy pasting my code from “GetCooldown”(which was marked as deprecated) to this new function.

I read that there were bugs with dynamic fields not working. Wasn’t this fixed in 3.0.3?

I’m glad for any information or help.

Move To / Jump To are entirely experimental. I’m planning to circle around to them this weekend. They may get removed as movement is such a per-game specific thing, but I’m going to see if I can’t give them one more shot.

Dynamic fields were fixed in 3.0.3, but I may have missed a spot with Cooldown. I’ll verify.

Pls…implement launch character in movement tasks. I wanna to make some aerial combat where I launch enemies to air and make combos…I puchase your plugin with the hope that can help me with this.

You’re going to have to get comfortable with making your own Tasks (either through Custom Task or through C++ and inheriting from UAblAbilityTask). You’re going to want to just apply some Z velocity to a character and then put them in some “Air Juggle” movement state (which you’ll have to create).

Again, Movement is so game specific that it’s near impossible for me to make “out of the box” solutions for people.

Doing jam using Able. Anyone had problems when restarting level? (only in build or DebugGame / DevGame without Editor) When destroying AblComponent it tries to call OnAbilityEndBP for “None” Ability. It isn’t null but just None object… cause to crash.

It appears when I’m extending abilities from other ones not from base c++ class.
