Multiplayer TopDown Kit

[Smartay]

@Pirate, I’ve tried using the PM system on here and the contact option on your website. I was just after some more information or any recommendations around replacing MPTopDownNetwork Pawn

@Askyl if I understand correctly when you “unpossessed the pawn” was this MPTopDownNetwork if so what were your main issues around it?

Hello Smartay,

The main purpose of the possession is to have the networked pathfinding. There wasa rough guide posted earlier in this thread about the steps to remove the pawn possession. If you are planning to use WASD movement or a better pathfinding system I would recommend removing the pawn possession logic. At the very least looking over that guide might help clarify any questions you have about how it’s all works together currently.

I’m actually considering updating the pawn to a character (you can prommote pawn > to character but not vice versa soit can still use all the same features) so i can use the gameplay tags from Epic a few other marketplace items need that as a parent too. The logic inside was staying I just needed to update the Pawn. I will look over the guide and see how it looks I may not be explaining or understanding correctly at present. Thank you

I’ve solved all my issues now except for two (I disabled click to move but did not remove it, since I might want to have that option in the game. So I have not removed pawn possesion). I’ll post my 2nd issue in the inventory thread since that’s the package I have a problem with.

In this package though, I can’t use “Rotate to mouse” for a character for movement. W is forward, towards where the mouse is on the screen. If I add this, it works on first character but not on any other players that joins the game.

If another player joins, he just spins around in circles. I’m not sure if that’s because player 2 try to read the mouse twice. From the first opened PIE and from the 2nd player PIE. Regular WASD (W north, D east, A west and S south) works for all characters if I remove the “rotate to mouse” code.

@Pirate could you maybe make an how to for adding your Advanced Social System into this project please?

Maybe anyone added combat system into this?

[isamual]

@Pirate you got mail my friend on your support email, and minus my own small technical issues, i bought all three of your products and they are really well laid out, keep up the good work

It’s pretty easy to create a basic combat system your self, and it’s a great learning experience. Just add small features, watch tutorials etc. I can recommend these youtube channels:

UE4 Combat

https://www.youtube.com/channel/UCRn…pXA0lccx_U1mww

They’re great! To add features like vaulting over objects, dodging etc, check out Root Motion for Unreal. All you need is an animation and it’s done for you!

If you really want to add a combat pack to your project instead I would suggest that you contact the person you purchased or received it from for help, they’ll either have tutorials or love to help out! That’s the best part with the indie gaming industry, people really want everyone to succeed.

Why is it now: Add to project??

[Bluntmaster]

@Pirate I sent you a pm.

[isamual]

@LinuxDonald

Why is it now: Add to project??

Yea, Unreal had an update for their asset library, a lot of assets were affected. This one should be fixed now

[stabbedbyapanda]

Was thinking about buying this till I came to the forum, and saw it only supports up to 4.16 in the original posting? Also this seems to have less updates compared to the action rpg inventory?

On a side note seems several people have requested melee from this and the inventory thing. are there any plans for those additions to either one or a new store Item you are developing?

[Bluntmaster]

Hope everything is alright with Pirate and that he is ok. I have been waiting for a reply to a PM and direct email since 11-10-2017.

I can see local hosted games but I get some other problems.

In editor everything seems to work perfectly. When try a build I can see hosted sessions with no name called 's game and 9999 ping, when I try joining it gives the error message that’s set for when joining a session fails.

Edit: After some googling about the 9999 ping I managed to fix it and now I’m able to play LAN or Online with my friends. This is a great product if you want to see how to get started.

​​​​​​​My problem was on a computer side not on a client side. I ve fixed it.
However I have one more issue, and this issue is in a default MultiplayerTopDown kit (4.19 & 4.20) on a marketplace aswell, as you can see on image 1 window - host, 2 window - client and on a client side player names are not shown. Any 1 who ve fixed it alrdy? Will apreciate any suggestion.

Thank you for creating a WASD tutorial It should help a lot of people.

For the WASD input though you shouldn’t need to do it that way with server events unless you want really strict movement input and logic for your game(In Unreal the character movement is already replicated to the server in an optimized way) and that is how most FPS games do it because it will probably end up flooding the server sending the direct inputs to the server.

If you are removing click to move you will probably want to remove having the client possess a pawn.
This method of possessing a server character is done in the MP TopDown Kit so that the click to move will work networked and with serverside pathfinding. It doesn’t really add too much overhead leaving it in and just disabling the click to move part in the Player Controller. But it would make things a little cleaner in your project if you are only using WASD for movement and just want to keep the mouse interactions to remove it.

If you are no longer using click to move at all in your game and want to remove the extra possession controller/pawn then here is a really rough guide I put together for someone on how to remove the pawn possession.

I will try to create a more formal tutorial in the near future now that more and more people seem to be interested in WASD only movement.

Guide: Remove Click To Move Possession

To remove having the player possess a server pawn simply follow these steps and it will get you most of the way there… or break everything.

Please backup your project folder before doing any of this lol…
*It’s possible unreal will **** out halfway through with a crash and mess up your blueprints.
In that case you will want to start over from the top with your backup. *

So the real trick is trying not to get confused by the naming of the controller classes and what they are for.

MPTopDownNetworkController is your games main PlayerController that is set in your game mode.
This has (should have) your WASD code and keeps all the exiting code it has, so nothing really changes in terms of it being your games player controller.

MPTopDownNetworkPawn will be your games main PlayerCharacter pawn that is (Already) set in your game mode.
At the end of these steps you will no longer need the PlayerCharacterController blueprint as the MPTopDownNetworkController is your main player controller and we are no longer ‘possessing the player’ and do not need the additional controller anymore.

[MPTopDownNetworkPawn Blueprint]

Open your MPTopDownNetworkPawn and reparent it to PlayerCharacter (from Pawn).
*(Later you can update the PlayerCharacter blueprint to have a Camera and the stuff that is in MPTopDownNetworkPawn and remove having an extra blueprint. But first get everything working then you can focus on trimming the extra character class.)
*

[MPTopDownNetworkController blueprint]

If you look at the variables the TopDownNetworkPawnReference is now what you want to treat as YourPlayerCharacterReference.
The MPTopDownNetworkPawn inherit’s from PlayerCharacter now so we will be able to easily replace the PlayerCharacterReference in the following steps.

We will be removing the PlayerCharacterControllerReference and the PlayerCharacterReference after we have made some changes to the RespawnPlayer() function.

Update the RespawnPlayer() Function to look like this image

Now you can delete the PlayerCharacterControllerReference variable.
This will update all the “Stop Movement” nodes that get called from using the PlayerCharacterController and will now have Self as the target. (Self being MPTopDownNetworkController)

You will get a couple errors with the movement code, this is fine as we don’t want click to move and the AI controller anymore.
Fix the errors in MoveToLocation() & MoveToTargetActor() by removing the Move To Location nodes.

Unhook/remove the UpdateFollowCamera() from the OnTick event because the Camera is on the character you control so it no longer needs to follow anything.

Right Click on PlayerCharacterReference and find everywhere it’s used in the controller.
Replace the references with The TopDownNetworkPawnReference.
*They will just plug right in because again since it inherits from PlayerCharacter and the PlayerCharacterReference was a PlayerCharacter it’s easy peasy.
There are a lot of places to update this but it should only take a minute working through the find results list.
*

After all traces of PlayerCharacterReferences are replaced with TopDownNetworkPawnReference delete the PlayerCharacterReference variable, then compile and save.

Don’t try and launch the game yet, If you try and launch now you will have errors in the NPC and the PlayerCharacter blueprints because they can’t find the PlayerCharacterReference variable that you just deleted anymore.

Simply rename TopDownNetworkPawnReference to PlayerCharacterReference and those errors will go away.
*Remember the TopDownNetworkPawnReference is parented to the PlayerCharacter so it is a PlayerCharacter class.
*

Now when you hit play things won’t be perfect but you are now a regular character with a regular controller.
You will have a few things you will no doubt need to clean up still but this should get you most of the way there.

**[NPC Blueprint]
**
You will want to open up the NPC blueprint and replace the cast to PlayerCharacterController with a cast to your MPTopDownNetworkController.
You will also have to repull off the get PlayerCharacterReference and plug it into the AddTarget node.

[PlayerCharacter Blueprint]

Then in the PlayerCharacter blueprint in the OnDeath() function you will want to replace the cast to PlayerCharacterController with a cast to your MPTopDownNetworkController you can now pull directly off your cast node to call the event ServerPlayerDeath

You can now delete the PlayerCharacterController blueprint. I would close and reopen the editor before trying to delete it though to clear any memory references.

**Now you have 1 PlayerController and 1 PlayerCharacter and no silly possession business. **

As mentioned earlier I will try and update this rough guide into a more formal tutorial in the near future. Please contact me at support@vanguardinteractive.com if you need any advice on adding WASD movement.*

Just to try to help Pirate out here… I know hes been off the grid for quite some time. I have been experimenting with changing this project over to 1st/3rd person and migrating the feel of the rpg inventory system rather than top down (in an effort to maintain his logic for online.) If you follow his rough example here like he said it does a pretty good round about job at changing it over, however, i noticed that respawn didn’t quite work as intended, was a simple fix screenshot provided. If i develop any new changes that i feel would benefit the community i’ll provide them. For the most part you’re good with what he provided and just moving logic over from the inventory player character. Attempting to fix jumping right now, i’ve updated the animbp and the input logic for it but its being stubborn. Anyway, if you want respawn to work properly add this one node to call character is alive again.

[Nejibana]

As for adding jump logic its a bit more complicated. I’ve successfully made the character jump, the only issue is that his height of the jump is less than satisfactory when compared to the normal 3rd person template. It is a work around tho… I’m sure if i spent a few more hours on it i could correct it, but this works for me for now. If anyone else has any insight on how to make the characters upward location/velocity please feel free to sharp shoot me. For those interested for now:

Ensure that you update your ANIMBP player state to the normal 3rd person (Include your jump cycle as normal) then add/update your controller ANIMBP event graph per the screenshots.

EDIT: this also causes a potential issue in that if the input button (space) is held it will loop the jump loop animation. Attempted to correct this by editing the jump max hold time, and even with the delay–stop jumping nodes this has zero effect.

EDIT2: Found the issue… this was way more complicated than i made it… go into the player nav mesh component and check box “can jump” use normal animbp logic for jumping… feeling dumb.
