Unreal Engine City Building Game - HUD and Building Select - Ep 8

[@THExRISER]

Alright, this is where I get off. I've been following this tutorial to build the skeleton of my game's level editor. Naturally I had to make a lot of modifications, since this isn't a level editor tutorial, but it's the closest thing I can find. Regardless, it's been invaluable to getting me on the right track, and now I'm ready to continue on my own. Thank you so much for this wonderful course.

[@lethiagames9208]

for later ue4 releases: in 13:14 change from visible to "not hit testable"

[@BOTS31]

Thanks!!! this took me a couple of hours -_-, should've checked the comments first

[@dejanpopovic7903]

Honestly, how did you figure that one out? Thanks, just curious what the thought process was

[@joeanrachelmiller6529]

I think that you have the most lightweight grid that I've encountered on YT. You are very right that most people rely on tick in spots they shouldnt. However textures not done in power of 2 tend to scale improperly and get that nasty pixelated blur with UE. I suggest that if anyone plans on porting a game outside of playing on a windows pc (xbox, PS, switch, etc) that UI textures should scale by power of 2.

[@lorentzstrachan6246]

Awesome stuff yet again. Looking forward to setting up building functionality.

[@thegamedevchannel3063]

Thank you! Hopefully that will be in the next few videos

[@hansknut2284]

Very good explanation again, keep on with the series !

[@dejanpopovic7903]

For Unreal engine >= 5, when you drag and drop the buttons, they are *not* by default variables. As soon as you drag the first button on the canvas, select the checkbox "Is Variable". If you don't do this, your button variables will not be available on the left hand side of 09:44

[@xSchallerx]

For anyone having trouble in UE5 with the widget editor, mine didn't automatically add a canvas panel, meaning I had no visible borders/anchors. Make sure to drop one into the workspace, and parent your buttons to it.

[@prasannakumar5813]

OMG! why didn't i find this channel all along!

[@thegamedevchannel3063]

I'm glad you've found it now! :)

[@kushs-labs]

Haha, I was just thinking when will you provide us with the next one. This is great. Though I believe I beat you to this point myself lol. Thanks for this. I also have some corrections for your videos of this series I'll be posting them as comments on your videos soon as soon as I'm done with Uni work. Hope it helps the community in general.

[@thegamedevchannel3063]

Haha, well I'm glad you're watching out for them! I'm trying to post a new video every Tuesday afternoon (it slipped to Wednesday last week 😬) That would be super useful if you find anything, it's really appreciated!

[@xXxteschio81xXx]

Hi, it's a really nice journey!!! Do you have any advice, maybe some videos to watch, to be able to eliminate or move objects already positioned? A thousand thanks

[@tbunreall]

There's a bug here and I'm not sure how to fix it. When you click the healthcare (road tile too I'm seeing now) button it spawns a healthcare building. You have your location set to -100 000, so you cant see it, but if you watch it appears in your outliner. EDIT: I Think I have figured it out. In the refreshPlaceableBuilding function. At the very beginning before you spawn an actor. Place an IsValid, drag a getPlaceableActor variable into the inputObject of the IsValid, and then drag out of the IsNotValid part into the SpawnActor

[@dilafroze5104]

Thank you so much. I was so confused for like the last hour. That really helped me out.

[@Faolon]

LIFE FRICKIN SAVER!!!!

[@majule1]

This may have been fixed already but to have the highlight appear on top on the icon, you can move the highlight image to the bottom of canvas panel list (or increase zOrder) and change the Visibility to 'Not Hit-Testable' instead of Visible.

[@dotnet14214]

Thx

[@julianaskuratovsky8701]

Amazing!!

[@ZenoFar853]

U make block overlap tutorial?

[@bananaknight8187]

for some reason when i click the button thats already selected it doesnt deselect.

[@ethandobell1442]

did you ever find a fix for this? Im in UE5 and having the same issue.

[@tbunreall]

@@ethandobell1442 Your image is in front of the buttons, not behind.

[@knop9528]

Loving the series so far, however I am finding that after the tutorial, clicking the icons does not update the placeable building/road, any ideas?

[@CiscoStu]

Im having an odd issue if anyone else had it, once I click any of the buttons I leave a building Tile placement highlight behind it doesn't matter which building mode I press the highlight will remain I believe it has to do with the On Placement Info Updated but I cannot find why does it leave the building Tile highlight

[@CiscoStu]

Managed to solve it, Awesome work on the videos btw! you could slow down a little bit wieh it get supper technicall-mathy-ish as it will be easier to follow

[@knop9528]

@@CiscoStu Sorry to message months latter, how did you solve the issue?

[@evantate1293]

@@knop9528 Player Controller -> Event Graph -> end of OnPlacementInfoUpdate Event: add a Destroy Actor after the Branch -> True -> Set PlacementModeEnabled False. That way, if the placement mode is disabled, it will destroy the floating actor on the screen.

[@MohamedSamy-vp2pq]

in this series u plan how to add curves and terrain in real time?

[@thegamedevchannel3063]

I do have a plan for this but that may be too advanced for this particular series. Basically you want to create a procedural mesh and keep track of each of the vertices, and then you can add in tools that can alter the Z value of the individual vertices to change the procedural mesh/terrain

[@MohamedSamy-vp2pq]

@@thegamedevchannel3063 i hope if u can do it it very important for building games thank u so much for ur awesome series

[@gamermaddox8433]

What are youre plans for all the episodes what are you gonna do with

[@thegamedevchannel3063]

I don't have a specific order, I'm trying to keep it dynamic so that I can make episodes based on requests from the comments

[@gamermaddox8433]

Thats good wil you do in a future episode a time system and a population system and a tax system

[@thegamedevchannel3063]

I will definitely be doing videos on population and the economy! By time system do you mean choosing a game speed?

[@gamermaddox8433]

Yes game speed to but that you can see what time it is too

[@thegamedevchannel3063]

Yes I'll do that in the future too :)

[@adam4designss]

Thank you for your effort, it's helpful for me, I've done all the steps so far, how can I with easy file dialog open choose which 3D from outside my game to insert by replacing my origins cb_building here, I'm sorry, I'm beginner so you can put it as a point for me, I know I answer to add a variable for 3D and materials but how to make this related to what has been implemented here please explain all the steps because I am a beginner

[@aureliengomez7623]

Excellent tutorial series, even a few years later!! I wish it would continue, but I assume you moved on to other things. Still, I realize now that I have performance issues on the game. It starts logically at 120 FPS, but as soon as I try to build, I go down to 10 FPS, as I move the future building around. And once I put it down, I stay at 16 FPS or so. Anyone else had the same issue, and might know how to fix it?

[@therealbugzi5670]

I'm not sure what happen, it's just not working anymore... the building and road does spawn on my cursor but I can't place them anymore. They also don't change color anymore to display if they can be placed or not. Upon investigation it seems the Is Valid in Spawn Building is hitting the Is Not Valid path. If I attach the is not valid to the spawn actor (skipping the branch check) it's working. Anyone know how can I fix that ?

[@simgamedev6423]

How many videos are there gonna be?

[@thegamedevchannel3063]

Honestly I have no idea yet, I plan to get through as much as I can as quickly as I can for the core mechanics and then I'll focus more on requests and polish :)

[@shigam8149]

Fixes for UE5: - In the Widget you have to Add a "Canvas Panel" yourself - When you Add the Buttons and Image, in the Details check the "IsVariable" Box to true

[@gamermaddox8433]

When is the New part coming

[@thegamedevchannel3063]

Should be next week on Tuesday or Wednesday

[@kelosrobi3770]
