Unreal Engine Action RPG with GAS #12 - Gameplay Ability - Damage and Kill

Project Files: / 100139956 .
This is the 12th episode of my new series on Action RPG game using Gameplay Ability System. Gameplay ability system (GAS) is a framework introduced by epic games that is designed to support a data driven gameplay programming architecture.
Here we are going to implement a gameplay ability which allows player to damage and kill other players in the game. As this is a multiplayer game, everything is replicated. So, when the player equip sword and attack other characters in the world, they will receive damage and then when the health drops to 0, they will die. Health is implemented as a attribute in a gameplay attribute set. So we will implement a way to listed to attribute changes in the character blueprint using a callback binding so we can check the health level and kill the character at 0 health.

Tips: If your ragdoll doesn't work, you need to create and bind physics assets to your skeletal mesh.

Having issues with the overridden UpdateHealth function. I cannot get it to call under any circumstances. Any easy ways to troubleshoot it? Thank you.

[@matthewfetsch4736]

@@ali-paskal My issue was that during troubleshooting the Datatable had detached itself. After every recompile of the custom C++ classes, I have to add the "BaseActorAttributes" back to the Ability System Component's starting data. Hope this helps.

Great video are you going to do ai death? When I did it I had add a death state tag took me forever to get it to work lol. Gas is so modular and nice.

[@CodeLikeMe]

sure, I will try that

Hi Sir....I was going through your awesome climbing tutorials from, like 4 years ago. My question is how would I modify those into a climbing system like Shadow of the Colossus/Praey for the Gods/Monster hunter where the player can climb a moving skeletal mesh?

[@CodeLikeMe]

what happens if you attach the character to the moving object?

[@MI-tb2ks]

Hello! Can you please clarify what you did at 7:27, when Update Health was changed to Update Health_Implementation?

[@MI-tb2ks]

Was it 'Create declaration of Update Health_Implementation'? I tried that and all works but every time I reload project it stops from working until I delete and add Update Health function again. Edit: Somehow, I fixed it.

[@3denvironmentmodeling]

how to use combo attacks using tags?

[@CodeLikeMe]

well, hard to explain in a comment, I will cover that in a future episode of this series

I have used unreal 5.3 here. Hope you are using the same. Also, make sure you have included all the modules in build.cs file and header files in the code.
