Editing the Projectile's Collision Settings. Using the New Collision Channel's Settings. Add the following code to the FPSProjectile constructor to set the projectile's lifespan:. Unreal Engine comes packaged with several preset collision chanels; however, the engine also provides customizable channels that game projects can use. Open Project Settings and select Collision to customize a collision channel.

Select New Object Channel Name your new collision channel "Projectile" and make sure that the Default Response is set to Block before clicking Accept. Select New Refer to the following image to set your collision presets. This collision profile specifies that the projectile will be blocked by Static ActorsDynamic ActorsActors simulating PhysicsVehiclesand Destructible Actors. Also, this collision profile specifies that the projectile overlaps Pawns.

So I'm trying to destroy a Destructible Actor within the Character BP, it all goes through the string appears but no damage is applied, even though it's specified, I've tried it with different amounts but nothing still happens, what could I be missing from here?

Enable impact damage 2. The thing is that I don't want to destroy them with impact damage, I just want it to be destroyed when pressing that key. Mine bp doesnt destroying meshes on impact Im using bp where is universal way how to destroy these meshesCurrently trying out some multiplayer stuff in Unreal Engine 4 and was wondering how I was going to add hitboxes to the controlled characters, since I have been so lazy at writing in my blog lately I thought I might write up a tutorial on the subject.

I started first of with thinking about the different damage distribution. I concluded that I wanted 3 different types of hitboxes.


One for headshot, I must have a headshot. This can off course be modified later with things such as damage over distance, adding armor that gives extra hp and so on, lets get to the basics of it first. The way I figured out to do it was to take collision capsule or a box and attach it to the socket.

In this case, it is the head shot capsule we are attaching. I am going to attach it to the head socket.

Set everything to 0. Then start scaling, moving, rotating it to fit the head better. I tried to name so that I could use the names later to determine if it was a body shot or, limb shot or a head shot. We need some specific collision for our hitboxes. The thing is, when a bullet hits, we want the bullet to ignore our capsule, it needs to fly trough the capsule and hit our hitbox. If it is stopped by the capsule, the hit wont register when we create the damage later.

This is demonstrated in the image to the right. I made two new object channels. I put their default response to ignore. Under preset, I made two new profiles. One for Bullets and one for Hitboxes. In the Hitboxes profile I made it ignore all except bullets and visibility the reason I want it to register visibility is because I later have to calculate where the character aims. Next thing we have to do is to set the characters hitboxes to the hitbox collision profile we made.

Now that our character is all set to be fired upon, we need to go the projectile. I am not going to cover how to fire the projectile or how to make the projectile. There are plenty of tutorials on that subject. I will even link to one above so you can figure that out. The important thing is that the projectile has a collision that is set to the bullet profile we made in our collision.

Damage in UE4

This is very important so that we know it will register right. It can get a little confusing with collision at times but after a little practice you will get used to it. On the mesh for the bullet I justs set the collision to ignore everything. On the collision you now have to get a OnComponent hit event.

As shown in the image to the right. You then have to get the hit result. Now in the end I have added a apply point damage. T he reason for point damage is that I wanted to calculate where hit came from and how far away the shot came from, I wont be dealing with that in this tutorial.Programming Basics.

Animation Montage. Blend Spaces. Audio System Overview. Slate UI Framework. Cascade Particle Systems. It includes basic implementations of weapons and gametypes along with a simple front end menu system. The base firing functionality for the weapons - such as ammo management, reloading, and replication - is implemented in the AShooterWeapon class.

The weapon is switched to its firing state on the local client and server via RPC calls. Once in firing state, the local client will repeatedly call HandleFiring which, in turn, calls FireWeapon. Then it updates ammo and calls ServerHandleFiring to do the same on the server.

The server version is also responsible for notifying remote clients about each fired round via the BurstCounter variable. Actions performed on the remote clients are purely cosmetic. Weapon fire is replicated using the BurstCounter property so that the remote clients can play animations and spawn effects - perform all of the visual aspects of the weapon firing.

Instant-hit detection is used for fast firing weapons, such as rifles or laser guns. The basic concept is that when the player fires the weapon, a line check is performed in the direction the weapon is aimed at that instant to see if anything would be hit. This method allows high precision and works with Actors that do not exist on server side e.

The local client performs the calculations and informs the server of what was hit.

Using the OnHit Event in Blueprints

Then, the server verifies the hit and replicates it if necessary. In FireWeaponthe local client does a trace from the camera location to find the first blocking hit under the crosshair and passes it to ProcessInstantHit.

From there, one of three things happens:. Confirmed hits apply damage to the hit Actors, spawn trail and impact effects, and notify remote clients by setting data about the hit in the HitNotify variable. Misses just spawn trails and set HitNotify for remote clients, which look for HitNotify changes and perform the same trace as the local client, spawning trails and impacts as needed.

The instant-hit implementation also features weapon spread.Posts Latest Activity. Page of 1. Filtered by:. Previous template Next. I have a custom projectile blueprint a bullet that my character fires from his weapon third person game The only way I can seem to get it to cause damage is if I use radial damage - so when the bullets impact something, I destroy them and apply damage - but when I use Apply Damage nothing seems to be happening That's what my projectile bp looks like How can I get this projectile bp to cause damage thats not "radial"?

Is there another workflow I should be using? I'm confused as to why Apply Damage isn't working. Last edited by digs ;AM. Tags: None. What are you applying damage to? Comment Post Cancel. I can't seem to get "apply damage" to apply any damage to actors or anything else I created a tutorial on projectiles over here! Hope this helps. Can I use "event hit" to kill someone? I have my projectile working, the problem is I can only get it to cause damage still not sure what damage is in ue4 when I use "apply radial damage" can anyone explain this?

If there's any other info you need about my level please let me know. You can set "Overlap Projectile" for your possible targets. For example, the components settings for a static mesh. And in the static mesh bp graph, handle damage with "Event Any Damage". And here it is the projectile settings. I started from the third person template I also don't have a "projectile" collision preset. Last edited by digs ;PM. Hopefully this will illustrate my issues better.

I know how to apply it to one enemy type, but if i will have multiple ones, i dont know how i would cast to the one my projectile hit. Im not making it to complex, means the only difference will be the health the enemys have.

As you see im casting to the hit actor directly, but since i will have more then just 1 type of this class. So how would i need to do in this case :S? Tags: None.

The way I did it is by creating one parent blueprint that holds all of the damage programming, and then creating children blueprints off of the parent. This way, they all inherit the damage function and you can "Cast To" the parent BP. As long as the attack is hitting a child of the parent, it will still be effected. Comment Post Cancel. You could have a base class that has all the basic logic for taking damage, and all the other "enemy types" are children of this class.

Or, and I would recommend this, you utilize interfaces. Sadly there is little documentation about it, but it's actually pretty straight forward. Well, that apply damage built in one is currently the best option for me at the moment.

I tried it once but now i actually know how to use it. So thank you both for the replys!! EpicForum Style. Yes No. OK Cancel.TSubclassOf is a template class that provides UClass type safety. For instance, let's imagine that you are creating a projectile class that allows the designer to specify the damage type. The sample code below illustrates the difference:.

In the second declaration, the template class tells the editor's property windows to list only classes derived from UDamageType as choices for the property. In the first declaration any UClass can be chosen. The image below illustrates this. If you try to assign incompatible TSubclassOf types to each other you'll get a compilation error. In the case you are trying to assign a generic UClass, it will perform a runtime check to verify that it can do the assignment.

If the runtime check fails, the resulting value is nullptr. We're working on lots of new features including a feedback system so you can tell us how we are doing.
