Let's Build the RPG! - 44 - UE5 Physical Animation Beginner Tutorial - Collision Damage

In this episode we set up Physical Animations, also known as Physics animations that simulate physics for our character's upper body when taking collision damage. I.E., the character slams into something too hard, too fast, and inevitably, they're going to take damage. Physics animation works off of the new experimental Physical Animation component available to be added to any character with a Physics Asset.
This episode builds off the previous two episodes 42 and 43 where we set up damage and health mechanics for our player character.

Im so impressed of how clearly u compress all the information quickly. Nice job, Thanks

[@American_Patriot_69420]

I tried this and the physical animations caused ue5 to freeze and crash... is it possible to fix this?

[@GameDevUE]

Would you be able to make speed takedowns so if I run up to the AI and press input on collision it plays the finisher😅

[@SLAPMYGORILLA]

7:52 Omg, dont miss this step. I thought i was brain dead bc my distance 2d was staying 0

15:53 why do you apply damage in the AnimBP? Pros/cons?

[@ijerofei]

have you seen the new feature called physics control? it would be interesting to know how to use it in a custom project

[@NumenBrothers]

haven't seen it- can you link documentation?

[@ijerofei]

@@NumenBrothers just look in newest content examples) It's super cool but there is no tutorials on utube

[@flyingmalkie4346]

If i added a boolean to fully simulate if over a certain threshold would the character actually fly back? with or withour adding impulse
and would that cause any issues like detaching from capsule or anything?

[@NumenBrothers]

Yes- so if you fully simulate (no root bone), then that is exactly what happens- the character will ragdoll completely and be detached from the capsule. A lot of games do that in terms of death animations.

[@flyingmalkie4346]

@@NumenBrothers i want higher level characters to be able to slap fools miles away, could i fully ragdoll, get world location and reattach the capsule in bp? Or however you get around this

[@NumenBrothers]

@@flyingmalkie4346 Yep! Just disable physical animations and reset the position. Do it!

[@kenalpha3]

@@flyingmalkie4346 Can you post your code on BlueprintUE or something?
I have a spin trip attack setup > AI plays fall down anim. But it is so unrealistic and the same each time, and doesnt react to nearby objects. I would like a jump start with what you were able to do. Ty

[@flyingmalkie4346]

@@kenalpha3 I havent actually implemented a system thats like organic ragdoll dependant on how hard it was hit, i got as far as making every hit a full ragdoll with varying levels of flying away, i suppose it does what the final 25% of the full system would, but if you watch prismaticadev vid on physical animation, you can do that upto a certain threshold, then afterward, full ragdoll followed by reattaching capsule as said above by op. I used alsv4 which already has a version of 'ragdoll>reattach>un-ragdoll" so i just reordered what fired those nodes, and added to the end of the code for attacking. You can also blend that physical animated hitreaction(ragdoll on specific bones, found it can look a little off by itself but im no expert on configuring it im legit total beginner) blend that with your actual animation montage, and you can also have different montages selected however you wish. Ive spent ore time on montage selection systems as its the kinda basis for what i wanna make but alas im not quite at that level. I

[@BigTurnz]

For some reason when I follow the above steps it instantly ragdolls the character. I've tried deleting a bunch of other things but it seems to be the change to the physics mesh to custom that is causing it. The Blueprint is identical to yours. Any thoughts?

[@NumenBrothers]

Compare your mesh's Physics Asset to the ThirdPersonCharacter mannequin Physics Asset and see where the differences are

[@SLAPMYGORILLA]

Check to make sure your PhysicalAnimationRecovery Function is recurring. I Changed a couple things and noticed that it stopped, and recreating the 'Set Tick by function name' fixed it for me.

[@NumenBrothers]

@@SLAPMYGORILLA sometimes function names suddenly have spaces inserted into them. Has happened to me on more than one occasion. Most likely culprit.

Crouching?
