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

[@matthewfetsch4736]

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

@@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.

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

Thanks for sharing

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.

[@edgarbartolomeu551]

Was this ever clarified? I have no idea what @CodeLikeMe did here. Weird editing probably missed a step. My project is not recompiling after that : CLMCharacter.gen.cpp.obj : error LNK2001: unresolved external symbol "public: virtual void __cdecl ACLMCharacter::UpdateHealth_Implementation_Implementation(float)" (?UpdateHealth_Implementation_Implementation@ACLMCharacter@@UEAAXM@Z) CLMCharacter.cpp.obj : error LNK2001: unresolved external symbol "public: virtual void __cdecl ACLMCharacter::UpdateHealth_Implementation_Implementation(float)" (?UpdateHealth_Implementation_Implementation@ACLMCharacter@@UEAAXM@Z) D:\Projects\Unreal\KA_5_3_v0003\Binaries\Win64\UnrealEditor-KA_5_3_v0003.patch_1.exe : fatal error LNK1120: 1 unresolved externals Failed to link patch (0.000s) (Exit code: 0x460)

I changed to the Sphere Overlap Actors approach and I'm concerned that the attack results in multiple hits which all take the damage value of the total. Is this how you intended it to work? I guess a full on hit will result in more damage than a side glance, so maybe a cool feature to have! btw - great series.

[@darkmuhu]

At first, the character is simulated well. After you apply UpdateHealth and turn off the Unreal program, UpdateHealth does not apply and the character does not collapse. So, after compiling C++ again, UpdateHealth in BP_ThirdPersonCharacter has an error, and if you delete it and rewrite it, it will be applied normally. Please tell me how to solve it.

[@CodeLikeMe]

after you close unreal, delete binaries and intermediate, that would force to re-compile at next start of the project and you will not have that error, or, if you open the project through visual studio as well.

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

[@jamaalsineke2405]

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?

[@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

@@CodeLikeMe Thank you for replying. I did and redid the tutorial. It only causes the error when I type UpdateHealth_Implementation which just shows up in the video at 7:27. Looking at the code I posted would you be able to spot the problem? Thank you
