[#06] Weapon pickups: Equipping weapons at runtime 

You’ve become my favourite RU-vid channel. Can’t wait for more tutorials.

I am really glad I have found your channel. After Brackeys stopped creating new content I was afraid I won't find anything comparable but I can proceed with learning Unity thanks to you :)

THIS. I needed this clever explanation. Thank you. It was a bit mind blowing.

Man keep it up another awesome one 💯💯 showed ya channel to a few people 💪🏿💪🏿

This is a great tutorial!! Thank you, hope to see more from you!

Using the Gameobject recorder was a nice touch. Thanks :)

My favorite channel this is want RU-vid needed different content not only just making FPP, TPP controller whole day

I'm waiting for your videos. What you do works for me.

man awesome. Bro keep it up.

YOU LITERALLY MADE MY MY DREAM THANK YOU VERY MUCH BRO LY :)

cool topic man thanks

This is great stuff and should deserve a lot more views. Overly simplified video title though. I feel many people might skip over this video, thinking it's just another "Brackey's level beginner tutorial" (no offense Brackeys) on how to use a trigger to pick something up, based on the video-title. (just my thoughts)

Dope stuff.

thanks!

Great video! A few twinks I found: 1. For AnimatorOverrideController you need to create a new instance otherwise it will set it for the asset: animatorOverrideController = new AnimatorOverrideController(animator.runtimeAnimatorController); animator.runtimeAnimatorController = animatorOverrideController; 2. GameObjectRecorder should have the root object as the constructor parameter, otherwise the created animation will not work. (It will not find the transforms, they would be marked yellow in the editor) GameObjectRecorder recorder = new GameObjectRecorder(rootObject);

For people having issues when they change and move things under WeaponHolder, like the results are your guys arms and weapon are out of place. Just go into playmode then manually start shifting things again. Move RightHand_Grip, LeftHand_Grip and your weapon back into place. Copy component transforms and it should fix. I am currently 4min into video, this is my solution.

you help me a lot thank you

Nice work again! When i see the code youre working also on fine tuning the character locomation. Many extra added like bulletspeed etc. Ive done the weapon change and hand locations by changing the local position. The local position is stored in "weaponRayCast" object. But this is a much smoother way doing it.

Nice videos bro, keep it up please

Nice!))) Cool!))

Where did you come with these information from? This is absolutely amazing. I was struggling with such things for months and you just came with this treasure! Good job :)

Thanks, your tutorials are even better than Brackeys' vids, straight to the point (though I can't blame him, his channel got so huge he can't cover all the stuff...). Again, many thanks and keep making great tutorials!

so damn good, a little advice, make your title related to unity , that's more easy to found by people.

Hey man, in my opinion you should include Animation Rigging in the video title, as I think quite a number of people are looking for tutorials to do with the Animation Rigging package at the moment and there's not a great deal of information/resources out there. Hopefully it'll help you with views and subs also. I think just adding "using Animation Rigging" or "using Animation Rigging in Unity" to the end of the title would be good. Or perhaps "Weapon Pickups: Equipping at runtime using Animation Rigging in Unity" if you're worried about title length and would rather it be a tad shorter.

Hey Kiwi loving this series for school project. Im having some issues with my hands following the weapon. Im doing things a bit differently using a sword rather than a gun but it is the same concept. When I move the pivot point manually my hands follow but when I run my swing animation or start running/moving the sword seems very static. Not sure what to do. Thanks

Alternative way of setting up the transform of the IK on different weapons: Create empty left/right IK reference on every weapon and put its transform in ActiveWeapon script (instead setting up animator) Let the Controller script have the active left/right IK when switch weapon set the transform of the left/right IK to the transform on the reference.

Amazing, any inventory system? Like changing weapons on buttons clicks and only pick when necessary?

Great video. I got a problem with the recorded animations: when I need to move the WeaponPivot from the original position of the riffle -> The WeaponPivot position is fine but the hands are bended really weird (not like what I setup before the save). Seems like it calculate the position of the ref_right_hand_grip and ref_left_hand_grip first, then move the parent object WeaponPivot later. I fixed it by moving the ref_right_hand_grip and ref_left_hand_grip right under WeaponHolder (so it's not the child of WeaponPivot anymore). I'm not sure if it's the right fix.

Great tutorials I love them. My only comment is that you're a bit fast makes me miss what's going on sometimes

13:00 If anyone else is having a problem with the hand layer rig weight not going to 1 when you pick up an weapon, and your hands stay down. The way i fixed it was in the 3rd person controller in the inspector, in animator i made the update mode to normal.

Amazing man, you are really good. 10/10 would marry. One question tho, what are you saying at the start of all your videos? _something_ this is kiwicoder. Is it something australian? :D

@TheKiwiCoder I am having a problem that in the animation override controller the animation clip changes I can save the animations to animations clip and I can see that in the animation clip after stop playing the game but when I play again then the animation is not playing

i cant save the weapon pose ? i can click on it but nothing happens ? any help ?

After making the weapon a prefab and putting it back in to scene, it equips as well as the IK, but the targets destination and tracer are removed upon putting the prefab in the weapon pivot. What am I doing wrong?

This channel is the bees knees of tutorials! Does anyone know how to assign the target of a two bone IK constraint through script??

since i added the equip function with the transform classes the weapon is spawning in my character and i cant move it, when i move the weapon mesh and restart the game the weapon goes back into the character. Edit : i must change weapon.transform.localRotation = from identity to Quaternion.euler(0, 90, -90) i hope that dont give error in the future

trying to follow your tutorial one by one, but it's hard because in each one you name things different, the first time I see that I should have inside the GO weapon, 2 game objects for the left and right hand, with a weight layer, weight of what? you don't have childs with constraints, and why? if you have a rig layer with 2 hands and you have right and left childs with constraints.

0:40 HOLY GREEN DUDE!!

Do I understand correctly, that the SaveWeaponPose we create here, as well as animator override is only needed during the game development, and when all the animations are in place, we may get rid of this method to not do excessive calculations during the actual game?

personally I find it useful to transform the handposition by script, each weapon transforms the position and rotation of the hands and with a parameter int called weaponID in the animator i use different animations, depending on which weapon you hold (e.a. rifle, pistol etc) for those who find i also useful to work this way, here is my script. modification needed to your wishes. Attach this script to your weapon prefab: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Animations.Rigging; public class RigTransform : MonoBehaviour { [System.Serializable] public class ObjectTransformData { public string objectName; //public Transform obj; public Vector3 newPosition; public Vector3 newLocalRotation; public bool hasNewValues; [HideInInspector] public Transform obj; } public List objectsToModify = new List(); public Vector3 thisPosition; public Vector3 thisRotation; private bool initialized = false; private void Update() { if (!initialized) { InitializeObjects(); initialized = true; } if (gameObject.activeSelf) { if (this.transform.localPosition != thisPosition) { this.transform.localPosition = thisPosition; } if (this.transform.localRotation != Quaternion.Euler(thisRotation)) { this.transform.localRotation = Quaternion.Euler(thisRotation); } foreach (ObjectTransformData data in objectsToModify) { if (!data.hasNewValues && data.obj != null) { if (data.obj.localPosition != data.newPosition) { data.obj.localPosition = data.newPosition; } Quaternion newRotation = Quaternion.Euler(data.newLocalRotation); if (Quaternion.Angle(data.obj.localRotation, newRotation) > 0.001f) { data.obj.localRotation = newRotation; } data.hasNewValues = true; } } } } private void InitializeObjects() { foreach (ObjectTransformData data in objectsToModify) { Transform parentTransform = transform.parent; if (parentTransform != null) { Transform objTransform = parentTransform.Find(data.objectName); if (objTransform != null) { data.obj = objTransform; } } } } }

Can we use scritable object for hand per diffrent weapons ?

Any advice for newbies coming straight from the previous episode? Everything breaks after deleting the weapon holding :( Game object is "RigLayerWeaponPose" for me, based on previous episodes

Just wondering if anyone else has run into this problem. The "save weapon pose" function works for me, but will lock the transforms if I try editing the same item again in runtime. Currently in order to change the transforms I need to make a new animation for it and save again.

after I removed the hand grips from the weapon now my character holds the gun slighty above the transforms

How about when we got 2 state (Idle and Aim, like in 1-4 tutorial), how to call animation aim or idle in runtime ?

The changing of the animations during runtime doesnt work

I have a problem! I'm working on first person game, I have same 2 guns(prefabs) on map when player picks it up I'm changing TwoBoneIKConstraint target from script depending on gun player is holding and TwoBoneIKConstraint target changes in inspector but it wont take effect in game. help please!

I feel like there is a more elegant way to implement this but still good tutorial tho

For me the character pick gun but the hands are not holding in runtime ( rig weight still zero) any idea how to fix? , work if weapon added before play manually , will try doing the next part 😅

Kiwi.What should i do if need holdweapon pose riglayer?

Great, what if we can play a weapon pickup animation and we can have 1 gun on hand and 1 on back. When we switch weapon there will be switching animation. This would be great ♥️

@TheKiwiCoder Please Help, I dont know what to do or even how to properly discribe my problem. At first everthing worked fine but suddenly the whole Rig-Builder-Animation Tool breaks my project. My Character-Mesh is walking faster than the actual player-collider. I thought at first my camera were broken but the Camera is still following the "Player" Component, the Player-Character (which is a child of the "Player" object is suddenly moving out of the Player-Object. If i turn of the Rig-Builder everything works fine again...

May I ask when im deleting my weapon and put it to the prefab it happens to have error can you guys help me what im missing here it says the particle system was destroyed but i dont see the error

When i equip the pistol, the pistol position is set to the rifle position.. i'm not sure where did i screw up.. any suggestions, help?

"Save weapon position" works fine but how can I set the gun position? Edit: I was moving the pistol model instead of the weapon pivot... my bad hehe Also, I can't move ref_left/right_hand_grip and WeaponPivot, it only worked once... why? :( Edit: Ok, I noticed to change grips you have to delete animation and re-do it (idk if there is another solution but that works.

Good job.... note... the invoke method as you type it didn't work with me... i use instead Invoke("SetAnimationDelayed",0.001); Just in case someone face this issue😉😉

Maybe I'm the one not clever enough, but if you have the same issue after previous videos with placing WeaponPivot gameobject inside of another object, this how it's should look: WeaponHolderRoot

The type or namespace name 'RaycastWeapon' could not be found (are you missing a using directive or an assembly reference?)

@TheKiwiCoder Your tutorial is very great and helpful to me but i dont understand why i have this error, can you help me? MissingReferenceException: the object of type 'TrailRenderer' has been destroyed but your are trying to access it . . .

I am having an issue. I was able to successfully save the rifle animation clip but when I attach the pistol and go to the context menu to save the pistol it only saves the weapon pivot and not the hand IK references. I have deleted it numerous times and retried and nothing is working. any idea what is wrong exactly?

This just doesnt work for me, ive tried multiple times but after setting up the weapon holder, everything just breaks. Then I tried to use the gameobjectrecorder in script and it is not recognised, I am using the unity.editor

In the part where we equip the weapon, you reset its position, but if I do that, the weapon is a little unregulated because the location of my weapon inside the "WeaponPivot" is not zero. How to fix this please?

Amazing tutorial! I having an issue when my player is equipping his weapon. He's able to pick up the weapon but his arms are not holding the gun. He's pretty much stuck on the idle pose. Any ideas or help from anyone? Edit: I had my player on Animate Physics instead of Normal

The weight of the handIK is not changing for me when I pickup the weapon any solutions?

i can not move hand grips during play mode inn scene view what is problem ?

Where can We get the 'Environment Box' to follow along?

@4:58 - when I try to adjust, the hands don't follow the weapon.

awesome video but how can i equip a weapon from bare handed model ???

Where can I get glass material that picked at 8:50 ?

Hello everyone, I need help, RigIK's weight is not set when Equipping weapons in the Equip() method, I checked Debug.Log() and in the console it showed that yes, the weight is 1.0, but in the inspector this weight does not change from 0 to 1, I need help, please help

please provide source code too like in drive WITH SCENE it will be helpful

3:42 i have a problem. my character just stops moving. im not using your locomotion. im using one i implemented especially for my game and it uses character controller. when the multi paren constraint references the weapon holder my character stops moving. i think its a problem with the hiercy because when i change the multi parent constraint reference to the weapon pivot it works. i tried EVRYTHING nothing works. please help.

why i cant move "weapon pivot"

Hey, TheKiwiCoder! First of all, thanks for this amazing videos, great job! But I wanted to ask you a question regarding setting the HandIK weight to 1.0f when equipping the new weapon. Seems like "handIK.weight = 1.0f;" it's not working for me and I'm not setting "handIK.weight = 0.0f;" anywhere but in the "Update" method when there's no weapon equiped which is actually equiped right when you do the pick up. Have any idea on why this could be happening? I can solve this by changing the HandIK on the update method if the weapon is equiped but it's different for what works for you and I've watched a few times the video trying to find the difference but seems like I cannot find it haha Thanks once again!

♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥

I'm kinda new to unity, can anyone please tell me what is RaycastWeapon. it gives an error when i write it in visual studio

Wouldn't it be more efficient to have the guns in a list and onTriggerEnter, identify the gun by its tag and pick the appropriate gun with the same tag from the list? That way, if there is already a weapon, we just return from the function. SO No Instantiation and no destroying.

I got a bug... The bullettracer gameobject is not been self deleted

I have the problem that for an unknown reason the weapon is not pointing to the crossHair anymore if I delete the Multiparent Constraint.

How do I pick up the weapon if only when I press F? i tried to update input in Update function, and call it in OnTriggerEnter....

If you cannot Edit the WeaponPivot or hands references at runtime, try deleting the keyframes from the weaponAnimation inside the weaponPrefab(weapon_anim_Pistol or weapon_anim_Assault). I hope it helps somebody else not go through the same frustrations :)

take for the help man make my own like gta

Who have problems with save function (nothing happens), I have this solution: 1) I've changed second paramenetr of function BindComponentsOfType to true (recursive) 2) After saving pose, my dumb ass realised, that i might to save whole project 3) In my deep misery I've decided to assign manually my animation with saved pose to my prefab. 4) My mf animations appeared! Hope this will help you

when i equip the gun the transfrom is off it goes like 2 feet above me lolol can anybody helpppp =p

Weapon equips correctly... But the position and hand ik weight are not working... Plz anyone help.... 🥲

we need to add enemies and deal damage PLSSS :)

3:40 my rig was completely disfigured :c

animation does not change

Tried to follow this and everything broke. The steps presented do not work as shown. There may have been updates overtime. Good luck getting any help from the dead discord channel

Recoil Plz ^_^ Recoil is the backward movement of a gun when it is shoot

you messed up all the things
