For anyone trying to interact in third person, here was my solution (not perfect). I replaced "Get Player Camera Manager" with "Get Player Character" in the InventorySystem Blueprint > Interaction Trace section, also changed "Radius" to 90 for "Sphere Trace By Channel". I wanted First person and Third person capability, so I copied over the interaction system again, so I had 2 versions, one with Camera Manager set with radius of 15, then another section with get player character with a radius of 90. These were both controlled via a branch, the branch condition was whether my player character was in First Person mode or not. (This was a variable I had set in my Player Blueprint). To get the condition of this variable. Add another "Get Player Character", then from return value drag off and then "Cast to ", then from the blue bubble that says "As " drag off and get the state of the variable you created in the character BP.

For anyone wondering how to do this in third person, I tried what others did in the comments to no avail, so what I did that seems to work well is: plug get player pawn > Get actor location > "start" in the sphere trace by channel , then I did get player camera manager > get actor forward vector then you multiply the return value by the interaction range variable, add the product to the return value from the get actor location from before, and put the result from the add node into "end" on the sphere trace by channel. Works perfect for me now

it seems there is problems with the player camera manager as reference, i have a better setup for the actor location and rotation which goes like this "Get Owner" ----> "get Actor Location"----> (add node) and another off get owner--->"Get Actor Rotation"---->"Get Forward Vector"---->(Multiply node) plug in interaction range float into the multiply node then that output plug into the add node then off of that plug it into another add node, split the struct pin of that one it should be orange and green, add another pin, then get 2 random float in ranges, and plug them into X and Y my ranges for x were min-50 max 70 and for y is -50 max is 50 plug that add node into start, pull off the add node and make a subtract node, the Z value should be 95 and plug that into end, this will try to trace towards the ground and this wouldnt matter FPS or Third person

My basic setup for *3rd Person* simply modifies a few nodes in the existing Interaction Trace function: 1. Replace "GetPlayerCameraManager" node with "GetOwner" node. 2. Replace "SphereTraceByChannel" with "CapsuleTraceByChannel" (don't forget to set the Trace Channel to "Interactive"). 3. Plug the Add node into *BOTH* the Start and End inputs of the Capsule trace (this will trace a vertical capsule directly in front of your character's capsule. Change "Draw Debug Type" to "For one frame" to visualize this). 4. Set the Capsule trace "Radius" to be at least the same size as your Character capsule's Radius. 5. Set the Capsule trace "Half Height" to be a bit bigger than your Character capsule's Half Height (so you can detect items on the ground).

Just to help anyone doing a top-down Game. You should create an input action called (anything that means iteraction) and then put it in your BP_Player, then get your mesh (or static mesh, or just whatever you are using for your character) to get its world location and forward vector. You should then get your inventory system and plug it into the Is Valid, and from the inventory system in your BP_Player, get your interaction trace. Now go into your inventory component by doable clicking on the interaction trace function, and once you have created two new inputs called world location and forward vector, go back to the BP_Player and put whatever mesh or static mesh you are using, world location and forward vector, into the interaction trace function. The interaction trace should activate when the interaction key is pressed, as you should not be needing to check if you can interact with something when you don't want to interact with anything. It should also save some performance. If you want to make it so something comes up on your HUD, then all you need to do is make a new function with the same layout but loop it on a Begin Play with a 0.1 delay or maybe even a 0.3, as this doesn't need to be responsive as the player interaction.

Everyone asking how to do this as a collision instead of a trace. Simply make the collision check on the player, check for overlapping actors, go through each with a break, make sure they implement the BIP and then if true set that to the inventory components target item. From there, call your look at function. This does not require the tick on the Inventory either.

This is excellent so far. Interaction system is super important for most games and the way it's done here is pretty much perfect. It's extensible so much that it will work on anything - NPCs, chests, doors, keys, anything the user can interact with, but also with some tiny additions we could have a separate type of interaction like press E to use/pickup, hold F to revive downed player etc etc :)

@@gamerdweebentertainment1616 by the way, sphere collision overlap is a sphere trace that happens on tick but only triggers an event when the trace hits. sphere trace however is still very cheap in terms of CPU cost, like line trace, but line trace is usually used much more deliberately which is why its initiated deliberately in your blueprint more often. sphere traces are more often done automatically by an actor component and your blueprint just waits for it to trigger one of your events so it's not obvious that the component is causing a trace on tick. (when i say "often" i mean how many times you add the node to your blueprint, not how many times the trace is executed)

Ok, so looking into this further and adapting, the way Ryan does it in the video is good for FPS. To do it for the third person, we have 2 nodes, either Get Player Pawn or Get Player character. if you plug these in following the above video, you will get an error "Accessed None trying to read property" To stop this error, pull off and find "? is valid" node. This works if you put it before the sphere trace by channel, The error stops.

Not sure if this will help anyone but you could make a instanced editable and expose on spawn first person boolean on the player bp. Call that boolean in the inventory component. With a cast to the player bp and the boolean following you then you could make a branch and for one branch have way it's done here. On the false branch you could do the same by making a second variable for the distance. So 2 variables called fpinteractionrange and tpinteractionrange. From there you'd tweak it as you like. Now if you wanted to do a capsule you could and make it directly in front of the player for interaction.

Imagine there's multiple objects close to each other. If the player's right in between them and triggers the interact function, ALL objects that are overlapping the player would respond. And if you'd set up a variable that stores the object to interact with, it would be the very last object the player has overlapped with-not the closest one. But yeah, I also wouldn't recommend using the Tick event. Just call the function via looping SetTimerByFunctionName. This way you can adjust how often it schould be called and even stop it by clearing that timer.

i should probably clarify why traces are good for your game but too many traces is bad for performance and the wrong type of trace is even worse. lets say you have a trace from your crosshair to see where you're pointing your gun. that's good. it's tracing on tick and your fps hasn't changed. now change the collision type to overlap on a window and block on a wooden table. if you look through a window with a laser sight on your gun - you can see the laser on the glass and on the table on the other side of the window. 1 trace on tick is now 2 traces in the engine. you might think that's fine but you still must be careful because it grows exponentially. now lets say you're in a multiplayer FPS with 16 players. each one has a trace for their gun. they have traces for each foot so they can stand on uneven ground without their feet going through the floor. they also have a capsule/sphere trace for checking obstructions (can't pass through a wall). just those things would be 16 x 4 = 64. You're doing 64 traces on tick already. now if everybody shoots at a bar full of glass bottles where a bunch of things have ignore, overlap or block, how many traces is that? way more than 64. what if you had everything set to overlap and you want to be able to shoot something 1 mile away? 1 mile long trace hitting everything along the way? and only each time a bullet is fired? your CPU usage is gonna spike up and down like mad, and if it's replicated your network usage is gonna be crazy too! good luck trying to optimise one object at a time :S

Honestly, after working with this system I think block by default might be better. Otherwise you would need to manually set every door, wall, floor, etc to block because without it, you can just grab items through walls and stuff. There's a setting to have line trace ignore self (which is on by default) and the ability to add actors to an array to ignore. For the few things you might need to be completely ignored, like the leaf example, you would just override the default. Obvioiusly every project is different, but if you're going into a building of any sort, especially one made out of a lot of meshes... it get's pretty bad, pretty quick.

Great tutorial, thank you very much. Just a question, when I have several players at the same time, when one of them calls "Look At" and prints "Pickup Test Item", all the players also print "Pickup Test Item", as if they all called "Look At" function. Although only one of them was the one who saw the object. What do I need so that "Look At" is only called by the unique player who saw the object?

I'm not sure if you figured out an answer to this, but I think if you add a custom event, click on it, and change replicates to "Run on owning client", that should make it so only the person looking at it can activate it, then hook up the "Look At" function to the custom event you created. Then, instead of using the "Look At" function in the "Interaction Trace", you just call the custom event you created. I'm pretty sure that should fix the problem.

Hey all, I'm trying to implement this and am absolutely scratching my head with one issue. I get an error message when playing as Client that it can't access the Player Camera Manager (while trying to do the Interaction Trace). I guess this makes sense because the InventorySystemComponent we created doesn't innately know who owns it? Essentially there's no reference to WHICH player camera manager we should access. How can we set/find the player index within that InteractionTrace function? FYI: The error message says: "Accessed None trying to read property 'K2Node_DynamicCast_AsPlayer_CameraManager,' Node: Line Trace By Channel... " and so on. I tried doing a Get Owner -> Cast to PlayerCameraManager (pure cast) -> Get Actor Location / Actor Forward Vector. Doesn't seem to work.

Some additional notes: the problems doesn't appear on the Server side and when playing Standalone. When I do the "Play As Listen Server" an interesting thing happens... When playing in the Client window, my interact (bound to left click) fires on both the Client and Server. Like not in the sense that it's working correctly and that the item was spawned/interacted with, but the Input Action of clicking fires for both... Is that just an editor playing issue or something with replication..?? Ryan your tutorials are so great btw; long-time subscriber!

Just an FYI to anyone who was starting with 3rd person. I made a 1st person camera with another ray trace line and crosshair widget; and thought the camera manager was not obeying the enable\disable toggle for cameras causing a duplicate print screen text to show up. It was actually just a 2nd BP_character I had on the level scene. Deleted the 2nd dude using the same blueprint and solved the issue.

If I wanted to use this for a third person character, what would have to change for the line trace channel to work properly? If you use it for a third person character the way it is in the video, the trace only picks up objects in front of you if you look up.

I figured it out. kind of. Instead of using "get actor location", you simply switch it with a "get camera location". It's as easy as that. almost. sadly, it seems to have a problem with accurately finding the y location of an object. I have to look up a bit in order to detect the box.
