@MizzoFrizzo Thank you for this tutorial. Prior to discovering this, I was following your 2 weapon system tutorial. Was wondering if you recommend separating the primary and secondary weapon spawns like you did here, or is there a simple solution incorporating the enum primary/secondary weapon class from the other tutorial? Thank you for your time.

[@MizzoFrizzo]

An enum is definitely the better way to go. Do a switch on enum then call separate 'spawn primary' and 'spawn secondary' custom events from there. There may be benefits to separating the pickups into their own classes as we did here, but I can't really think of any off the top of my head! 🙂

hey there mizzo! i just finished this tutorial today and i gotta say this is great! i loved it and keep going man its these things that will make you rocket up to the sky the more you put work into this channel. u will be a life saver for lots of new devs!

[@unholynimble5723]

I got so excited about the mouse wheel weapon switch, been wanting to figure that out for ages. Guess I'll just have to give you more watch time.. not like you don't deserve it! Nice job man, thanks :D

[@KonsolenGames]

Appreciate you sharing your knowledge. Thank you!

[@aakburns]

You are far to kind man. Appreciated.

Hey, just want to comment that you got "se up" in your title and not"Setup". Awesome video by the way, super useful and easy to follow!

[@QuantumPixelJoystick]

Amazing ! Thanks

[@JD_Main]

Hey there, I found your channel recently and have been loving the videos you have highlighting network replicated functionality. Is there a way to contact you about some issues I can't resolve regarding this particular video? Cheers

[@luistgarcia]

I have a question if I want to add a camera to the skeleton components for when the character is going to aim from where would I do it? How do I add that camera?

[@Rev0verDrive]

Just curious if you're using simple static mesh bp classes for the world items? Most devs I come across are spawning the full weapon class as pickups which crushes server & client memory. Better to have a simple BP with mesh, interaction collision, gameplay tags (interface) and a struct for skin data. Have the server destroy/spawn or pool manage as needed.

[@MizzoFrizzo]

Yes static mesh pickups.

[@SuperMan-nv6iu]

Hey. Thanks for the tutorial. One small query. How is this tutorial different from other weapons systems tutorials of yours? Is this the updated version?

[@MizzoFrizzo]

This one's replicated

[@TheAngryRubberDuck]

Never stop

[@MizzoFrizzo]

Ducky! You're too kind... My girl has gone traveling indefinitely so I haven't been up to the task lately but I'm starting to feel a little better; I'm actually working on a weapon system for the FPS Series as we speak! Thank you so much, I won't be stopping... 🫶

[@TheAngryRubberDuck]

@MizzoFrizzo that sucks. I hope all is well. I've actually been through something similar when mine went to Australia. But I can tell you that everything gets better and I've even forgiven you people. I've been going through it for the past couple of years and game development has really helped me. Your tutorials were no where close to the first I've gone through but are absolutely the first to make things make sense. So the odd 'super thanks' is an absolute bargain for the value.

[@sisqobmx]

hey, another question. I have followed exactly as you but at 1 hour 35 min, where we set up the weapon switch, it doesnt replicate properly for me somewhy. Can using an actor instead of component cause issues related to this?

[@flooosee8437]

Hey, how can I add like accessories to weapons, like my current rifle have the stock and the mags separated from the skeletal mesh. In a previous turorial you made for the weapon system that wasnt replicated i could just add them in the BP of the weapon directly, but in this one there is no "viewport" in the BP of the weapon. Do I need to create a variable "accessory" pointing to a socket in Weapon_Master?

[@MizzoFrizzo]

Yep, exactly. 🙂

[@sisqobmx]

Hello at minute 49 where we set up the weapon to spawn when we pick it up, how could i attach the component to an actor type of input? I have a thing that updates procedural data but it only accepts actor type of input not component. Any tips? Btw you're a very good teacher, was a blast to follow along.

[@MizzoFrizzo]

Maybe make Weapon Master an Actor instead of a component...

[@sisqobmx]

@@MizzoFrizzo That did it, thanks a bunch dude!

[@daybydaylight712]

@@sisqobmx So basically just do the same as in tutorial but in place of component use Actor ???

[@sisqobmx]

@@daybydaylight712 yep, when you’d create the blueprint component, you right click -> blueprint class - > actor ( the first option) you will also need to change the variable types which specify bp weapon component master to your newly created actor instead

[@doomlord5236]

This tutorial is amazing it save my project lol keep it up but im wondering how to give each gun a damage type like if u pick a gun that shoot rapid and u pick another one that only shoot one shot at a time i wondering if i xan edit the fire mode in each of the wepon pick up to make diffrent fire mode when pick up weapon ?

[@MizzoFrizzo]

If you wanted to have each gun have its own uniquely firing properties, you could do so by containing the firing logic inside the weapon component. Just create the 'fire' function inside weapon component master and call that function as part of your character's firing logic. 🙂

[@doomlord5236]

@@MizzoFrizzo ohhhhh ok i will try it thank

[@doomlord5236]

@@MizzoFrizzo update it seem to work each weaon fire diffrent thing now but it cause alot of error when i try to replicate it

[@chronickev_]

Would there be a way to use another input "g key" to drop a weapon rather than only dropping when you pickup a new weapon?

[@MizzoFrizzo]

Of course

[@aakburns]

Are you able to address the left hand? How would you go about setting the left hand placement per gun? I have some hand sway going on and that left hand while lined up correctly when not moving, it does not follow the weapon when looking around.

My friend, I got stuck on 42:15 on Spawn Primary Weapon where you dragged from Weapon To Spawn, in my case i dont have option to Add Component from Class, that I can connect to Weapon To Spawn... Any ideas where to look?

[@mattpur8486]

EDIT: It was because I used Weapon Master blueprint from previous videos and that was not Skeletal Mesh Component Blueprint!

hi was wondering if you where also going to add an online multiplayer tutorial ?

Maybe one day. ✌️

0:03 Ahah what's happening with second mannequin?:D his head went brrr

[@MizzoFrizzo]

Yeah it's an issue with the replicated aim offset I'm currently trying to work out. 🤔

[@MizzoFrizzo]

It's just a problem with the lower LODs of the mannequins, maybe skin weights. It can be solved by locking to LOD 0 or deleting the other LODs.

[@mikska]

Hi, Do you have a tutorial that adds ammo clips as pickups with specific tracers for that ammo and damage?

[@MizzoFrizzo]

I have an ammunition inventory tutorial with different ammo types, and if you wanted to add ammo-specific tracers would be easy using that system. 🙂 kzbin.info/www/bejne/amHOc4aDrc2pidU

[@mikska]

@@MizzoFrizzo great, thanks you

[@DarkHorizons13]

Now all I need to do is make a projectile spawn on fire, but I don't know how to attach it to the Blueprint component only a blueprint actor. Can someone enlighten me?

[@Vylocity]

Hey! My weapons are separate static meshes(base, mag, slide, trigger, etc. that I attach in a blueprint for each gun. I see this uses a blueprint component which works because its a skeletal mesh. It is possible to still use this system with a BP of the weapon and not a BP Component of the weapon, but follow all the same logic? I tried static mesh component but it only allows for one mesh.

[@Vylocity]

FYI it did work with your other simulated physics weapon tutorial which is pretty cool :)

[@MizzoFrizzo]

You could make static mesh components that are children of the base static mesh, or you could just make the base class a BP and instead "attach ACTOR to component"

[@Vylocity]

@@MizzoFrizzo so with your last suggestion, I could attach a BP of the weapon and its parts, to an empty component with the same settings as your BP_WeaponComponentMaster? Sorry, just trying to wrap my head around this new territory haha

[@MizzoFrizzo]

@@Vylocity It should do, but that's really up to you to find out. Good luck! 🙂

[@HarshTambe-wg1yw]

Hey is This System Compatable With ALS system as you know most of the Animation in it as Replicated just Need The weapon System

[@MizzoFrizzo]

The theory is applicable, but you would need to make it work.

[@NeilClarenzSanMiguel]

do you have a tutorial where the AI becomes visible only when you have this certain item, for example a flashlight

[@MizzoFrizzo]

I do not. That would be quite tricky!

[@korypeters2059]

I'm stuck trying to fire a sniper then switching to my assault. I only have the one firing logic, etc

[@MizzoFrizzo]

Make a boolean called canfire?, set it as false when you fire then put a delay before setting it as true again. Put a branch before your semi-auto logic with canfire? as the condition. Hope this helps.

[@a1zombieslayer148]

hey there mizzo i had a question its a more complicated one but how would you go about combining this weapon system with an inventory system? (spatial based inventory to be precise) ive never done that in unreal and i really don't know where to start to combine the two would i just make the system as a child of my item class or would i want to call functions as needed, or would i skip the sections on the two weapon system and use my inventory system instead? im trying to make a system kind of like dayz if that helps

[@MizzoFrizzo]

It depends how you set up your inventory system. I can't help you I've never played Day Z.

[@unjustifiedexistence9369]

​@@MizzoFrizzocompletely get it thank you for the quick response the way the inventory is set up is you have the item you pick up it goes to the inventory and you can drag and drop items around. each item has certain dimensions for fitting in the inventory say its a 7x7 grid and an ak is 6x2 it would take up that many slots of the inventory the ak item blueprint holds the information concerning the parts of the inventory around the ak. Im just wondering what the best ideas would be to integrate your weapon system into an inventory like if I should make the weapon master a child of my item bp so they all have the functionality of the inventory or if I should make them 2 different things and use an interface to change which one im using

[@MizzoFrizzo]

@unjustifiedexistence9369 Yeah that's up to you, my man. Good luck!
