Unreal Engine 4 Tutorial - AI - Part 8 Melee Attacks (Animation)

[@toniconge7003]

OMG That's so cool! Combining the animations of running and punching into one! I always assumed that would be mega ultra super difficult while I don't 100% get how it works I do have it working on my level.

[@maxostlund9334]

5:30 instead of clearing and adding the animation again you can simply save the montage, exist and reopen it. :)

[@peacockgames4364]

Not sure how many people this applies to, but if your character stops moving while playing the attack animation, make sure you have "Enable Root Motion" turned off. This can be found in the original animation sequence

[@s.kanessuperbiatv6464]

This saved me bro

[@jasonfry920]

Encase some of you find that your animation might not be working when implementing the Simple Parallel task, check your MeleeAttack task has the Finish Execute success flag ticked! This took me ages to figure out. Lesson learnt.

[@ScoutOW2]

Heres an idea for what i did. Instead of charging at you instantly, a small meter that they only go into combat mode if it becomes full, but if not in combat it slowly drains. Makes stealth games more enjoyable in my opinion.

[@canisterbottournament]

for those of you who don't see event melee attack, but you see the function version of it, just reassign the CombatInterface in class settings and reopen NPC

[@АкимПанов-д1ж]

THANK YOU!!!

[@shandybka]

You are the best. Briefly clear and cool

[@wearetheroyalsgames1464]

Okay, at first try i thought it wasn't working and very bad cause of that, but as usual i messed up big time by not paying enough attention, SO... Thanks so much cause you really helped me a lot and made my game so much better looking!! (As for my big time mess up.. i did everything in an animation instead of making a montage(Still a bit impressed on how far i came!))

[@GaryParkin]

I'm not really sure I understand some of this, but I'm following along. (I have not messed with montage yet) Bt this is really cool. Thank you again Ryan.

[@SevenYearsGoodLuck]

Bro, you are an excellent teacher.

[@RyanLaley]

Thanks Jason

[@DangerSideburns]

When he fixes the error make sure you're setting your key in the behavior tree.

[@jaxxrr]

tnx man

[@levithefisherman3363]

Where do i set the key? Cannt get looping to work

[@canisterbottournament]

@@levithefisherman3363 in loop path when you made BB_direction (it has to be instance editable) and in your behavior tree you should have 3 editable instances: BB Path Index = PatrolPathIndex BB Looping = PathLooping BB direction = Direction

[@stuartwright2531]

Thank you legend!

[@nothingspeaks]

to make it show the anim after you change the slot, you dont have to delete it, just grab (hold left clikc and drag) the green bar and move it a bit

[@vivegamespk]

Learning alot from your tutorials

[@Lolpop751]

Amazing, thanks buddy! Would love if you go more into 'interface's - Haven't used them before and sound great for these types of thigns!

[@zinx-YT]

If you can not find anim graph this is how to find it go to window what is on the top bar then click find results it should show on the bottom search anim graph if you not using the third person animbp it might look different

[@sstudio5373]

Thanks!

[@alessandragarber20]

That animation really helps!

[@finanzenkeine]

one of the best tutorials i had the pleasure to watch!!!!!!!! thx alot for making such awsome content gj mate

[@Dsean126]

For some reason the montage fails to play the animation in the engine. Event Melee Attack is called, and it completes the play montage BP, but the actor itself isn't doing anything but its normal idle animation. Any ideas?

[@yiannisathanasiadis4532]

I'm having the same problem. Have you found a solution?

[@Dsean126]

I haven't. Instead I changed the way the characters operate and made them run from the player, making it a game of chase instead of combat. I don't know if that idea is compatible with your design though.

[@ambestenvideos1713]

@@yiannisathanasiadis4532 You have a 2 different AnimBP. Use your oldes or change for newone in Character BP, right upper angel - AnimBP - then change it

[@LiliuD]

Same problem here , it plays the idle animation instead of the attack anim.

[@Fettman89]

By the end of this video for some reason my Blend poses isn't working right, in stead of running and swinging, he runs, stops for his animation, then slides across the ground for a brief few seconds before going back to his regular pose again, I got a not a great fix by adding .5 second cool downs going between the paralell and change status, and he only slides across the ground a little less, but still does it.

[@cyberrb25]

The Event Melee Attack doesn't appear on the NPC Event Graph. Is there someone who can repeat all the steps to exactly get to it, so I can retry -- I'm not sure which are the ones required and which aren't.

[@cyberrb25]

Update: I don't know what I've donde, but now it works. That is so confusing -- I won't know how to fix it were it to happen again!

[@sonicherores]

@@cyberrb25 I know its a late reply but I did the same mistake if I am right you forgot to compile on the CombatInterface after you typed in melee attack

[@sdehues]

Around minute 8 when adding Slot to the ThirdPerson_AnimBP, the UpperBody slot is not available as a choice in the Slot Name dropdown box. If I click the magnifying glass icon next to the dropdown box to open the Anim Slot Manager, UpperBody is not shown in the ThirdPerson_AnimBP. When I switch back to the Montage it is there. AttackPrimary_A is in the Montage animation and UpperBody is selected there. Everything compiles and the level runs, but no attack animation. I have saved everything and restarted the editor without success. I've been through the video 3 times so I don't think I'm missing anything. Do you have any advice? I absolutely love this series of tutorials BTW.

[@corej5424]

I've been having the same problem, have you found a solution?

[@youviewteam]

same here, i gone through the last 3 videos and i dont find anything i made wrong :( I just want the NPC to slap!

[@Meeizter]

nice tutorials!! =) but this attack animation link aint working :(

[@stinmanstew4582]

how would i go about this if i have two different characters, myself(mannequin) and enemy(griffon from quadraped creature pack), each with their own animation. the attack works fine for me as im still playing as the mannequin but the griffon does not play the attack animation when it attacks! it is lunging forward so i can tell it is clearly doing the attack but no animation. Someone please help I'll love you long time, been trying to trouble shoot for 2 hours now

[@augusttell]

Also missing this solution

[@iliaspsomiadis319]

Ahmm 1 question, you use the same anim bp for enemy and character?

[@ainigma100]

When are you going to upload the attack-damage video. I do not know how to make the enemy attack me so that they can damage me. Thank you for the tutorials!

[@josebenavides1850]

Have the enemy character play an attack animation and add an event notify to your attack animation montage called damage player or something like that. In the enemy animation blueprint create an event notify event for the notify you created in the montage. Every time the animation is played it will fire that event at whatever time in the animation you set it to. Have a line trace between the enemy hand or something to the player location. If there's a hit you know the enemy hit the player so apply damage to the player

[@nubsdubs6049]

For some reason it keeps attacking when out of range went from 500 to 250 to 1 it still swings aslong as it can still see the player even though its set to proc when within meele range

[@SCREAMOguy413]

you are a fantastic teacher!!!

[@originallmoney9099]

Do you have a tutorial for adding this melee attack to a first person character? I could make the montage easy enough, but, I can't see my character attacking.

[@brno322]

Agree this would be super useful

[@levithefisherman3363]

How can i set a blackboard decorator for "has patrol point assigned" so i dont grt errors for characters i want to be static until they see me

[@justindeines6724]

I am having an issue that I cannot seem to figure out. I didn't create a montage because I want my AI to use full animation. So instead I am using the Play Animation node. What happens is, the AI uses the attack animation like it should, however the AI then stops every other animation other than Idle. Would I need to update the Anim script on the AI so that it can transition from the states? (I did try the montage but without making changes to bones and such, but the attack animation did not play.)

[@BadWinterStudio]

am i suppose to use the same skeleton for this to work?

[@SomethingClever3385]

i cannot follow along with this one. my screen montage windo dosnt have all of the things yours does and i cant seem to find how to open those things up please help

which paragon character is this from?

[@nightdragon4611]

This is my first go around at behavior trees and you do a great job at explaining it and how it works, I do have one question though, will I need a different tree for each enemy? For example I have a Troll enemy that I want to be very slow, but I can't edit the speed just for one enemy, should I duplicate just the tree? Or do I have to duplicate everything including the tasks?

[@mwilsonjr92]

I suggest making a children of the base AI and adjust the setting as needed for each of them.

THANK YOU FINALLYYY I CAN ATTACK

[@废物点心-n2g]

Sorry i cannot access the attack animation link. How can I download it? Do you have other links?

[@righy2711]

i know this has probably been adressed already by ryan, but, if someone wants to make the character/npc play the full animation, just do: add new boolean variable called IsAttacking and leave unchecked. on input attack add a branch, use IsAttacking as condition from false, set isattacking to true, then play montage from there from On Completed, drag a pin and set isattacking back to false. this wil make the actor check wether the montage is still playing or not.

Doesn't do anything

At 3:40 - "And this is what the montage screen looks like..." Um, no it doesn't. Not mine at least. lol I have no timeline that shows up in the middle of the screen like in the video. Then at 5:40 - Unable to figure out how to get the timeline to show up so I can drag the montage file onto it. Mine didn't show up by default, and following the descriptions in the comments didn't help unfortunately. Usually I can poke around and find the window I need to add, etc, but I'm totally lost now. I suspect there are some additional things one needs to understand regarding animation in UE, but I have very little experience in this part of the engine. Is there some preliminary setup I need to make sure the montage screen looks like that?

[@RyanLaley]

In 4.25 they changed the layout a little. Sections are now on the right hand side in their own panel

[@RJ-zs5mo]

@@RyanLaley Thanks! Do you know which panel it is? I'm struggling to figure out where this timeline is now showing or where to drag the montage to. Did they change the way this process is done? I'm not familiar with animations in UE. There's a "Montage Sections" tab, but I can't drag anything into it.

@@RJ-zs5mo I am in the same boat. I have no idea how to set up this animation blend because I don't know where to move the animation too. Did you ever manage to figure this out. I looked in all the documentation sections, related to this and they are still showing the old montage section.

I realise it's been a couple of years since this video series was made, so I'm sure you know this already by now, but with full-screen UE4, 1080p is barely enough resolution to be able to read the text. For future work, higher resolution would make things easier to see and follow. (also: kzbin.info/www/bejne/eaDWhYd-f6eMf6M)
