Unreal Engine City Building Game - Mouse Cursor, Click Object In-World and Highlight Material - EP 3

[@Justicefu]

hint: promote to variable will save you a lot of time and right click -> 'convert to validated get' helps keep things tidy instead of using 'is valid' nodes on your variables Really cool tutorial though, thanks

[@JonoJamesJonoJames]

3 things cleared up , Actor components , Mesh Selection ,Highlighting Meshes good clean blueprint code and easy to follow . Thanks for that

[@itanshi]

A way to clean up the nodes in the clickable component bp is to create an event via event dispatcher category. it gives a drop down to select the event. So you can split up the events.

[@gianclaudiomorando2392]

Hello. So, could you explain how to create the event dispatcher to print to screen a drop down window to select the event? many thanks.

[@samuela6271]

So good! This is a great effect! I'm really enjoying your thinking and approach to your game! Thanks for the info!

[@KayPhantomville]

I wouldn't mind a more detailed explanation of why you use certain blueprint nodes, or at least being slower and a little less concise when doing so, just when you explained the highlight material. I know you have a lot of stuff to cover, but for a beginner like me and many others it's difficult to understand the reason behind your choices. For example, while the camera tutorial was very clear to me, I didn't understand the logic and purpose behind the StaticMeshRef thing at all. I wouldn't want to end up copying your work without having the ability to tweak it later if I'll ever want to do something different. Other than that, thank you for your tutorials!

[@veemex]

This explanation primarily revolves around fundamental concepts in Unreal Engine and the idea of a game loop, along with some optimization practices. Though I may not be an authority in this field, let me try to make it as straightforward as possible for you. In the game engine, there are two events that are constantly active: BeginPlay and Tick. To clarify, Tick is an event that gets triggered on every single frame, meaning it's continually operating in the background. On the other hand, BeginPlay is an event that activates only once, which is right after the game starts. The reason you're storing the reference to a static mesh once during the BeginPlay is because the mesh itself isn't going to change. If you attempted to call GetOwner and GetComponentByClass every frame during the Tick event, it could lead to a slower performance due to the extra time required for these operations. Also, it might make your code unnecessarily complex.

Following tutorial in UE 5.3, encountered black highlight border instead of blue, resolved by changing Blendable Location back to After Tonemapping @8:39 I don't know anything about UE, so if anyone has follow-up questions about this I won't be able to answer them. I figured this out by just going back through the tutorial and changing values to see what impacted the outcome and for some reason leaving this value as the default worked so I figured I would post this to help anyone else that encountered the same issue.

[@Punchmememe]

When i zoom out it make the outline so big that the block go's ful colour. How do i fix this ?

[@sleepypapercrowns]

Thank you so much for this video! I needed it for my project and only found really old tutorials before that I didn't understand and that did not even work anymore. So thanks a lot!

[@thegamedevchannel3063]

No problem! I'm glad it helped

[@thomascurtis889]

Great tutorial, any help on changing the colour of the outline when clicked? I've noticed you can have multiple materials in the post process materials and have created two instanced of the material with different colours, however I have no clue how to change between them when I click the object

[@Luna-gleam]

You could make a parameter in the material and change that parameter in the blueprint. However, I'm not sure if you'd be able to have two different colored outlines at the same time with this method

[@eggwithtofu7295]

why CB_Clickable_Component didn't work? i have tried so many time and still didn't work

[@IamAxe163]

The same, iam make the same how on tutorial, but it does not work =/

[@unrealdevop]

The Outline seems to get thicker or thinner depending on how far I am from it. Did I do something wrong? I went back twice to double check

[@unrealdevop]

This must have been some sort of bug, for some reason it stopped doing it on it's own.

[@manollobango]

Hi, I just started to watch your city builder tutorial series today and I really appreciate your kindness to share your work! Since this video is almost 2 years old and besides that Unreal Engine 5 has been released, I'm wondering now if you would, based on your current knowledge, change some things like the camera movement system and the actor type or would you do it exactly the same today?

[@jeffreytablan4043]

Hi, sir! I really like what you did here. I would love to integrate it in a project that I've been working on. However, as I did all the steps, the highlight doesn't seem to work. It would only show briefly after you clicked on the mesh and disappear again. Any insights on where do you think I might went wrong?

[@liangmen]

Make sure you checked the "infinite extent (unbound)" in the property window of the PostProcessVolume, it solved my issue

[@kiwk8139]

My highlight works. The switching between red and green works, but not at the same time. The highlight only works when I assign the material to the CB_HighlightMaterial. However, it is black. And when I click on it, it becomes green with no highlight upon hovering anymore. I can't seem to get the green/red AND the highlight at the same time

[@kiwk8139]

Fixed it. I had to go into my Red and Green Materials and set, "Allow Custom Depth Writes" to true. As well as the option Render after DOF" set to false.

[@vkum7500]

Thank you for the tutorial. Do you know what to change in material to diable see-through from walls or other objects?

[@thegamedevchannel3063]

If you look at the next video I believe I go over that, sorry for not including it in this one!

[@AcTAL0n]

Brilliant Tutorial! Well paced and super informative, thank you a lot for that :)

[@thegamedevchannel3063]

Thank you very much, glad you're enjoying it! :)

[@oculusidirisov6981]

does not work on transparent glass please help

[@AMobOGobos]

Around 5:00 you start building the on click events for static meshes but you never showed or explained how you created the red and green materials. How do I create these materials? Where do they appear once they are created?

[@christopherlamott9351]

Anyone know why the selection would work on both left AND right mouse click? I'm really scratching my head here, haha.

[@Regisseur12]

Nice!!! MoseOver Effect was exactly, what I was looking for!!!

[@nullptr7347]

It doesnt work when i have transparent materials on the object.Is there any way to make it work with transparent materials ? Appreciate any help!

[@Lagimaster-gf8wr]

3:54 had some problems with static mesh ref as it isn't compatible with return value in get component by class. Could someone help me?

[@ItsExetic]

How come the highlight doesn't work on quixel assets, but clicking on the mesh to change material does?

[@lethiagames9208]

if you zoom out then the highlight effect gets off

[@3dchuy]

Awesome tutorial! one question If I also want it to affect my vehicle (Skinned Mesh Component), DoI just duplicate everything and changed the variables for that kind of mesh? or is there a more simple and efficient way to make it work on both. Thanks!

[@3dchuy]

Ahh! I figured it out! I was getting an error on the mouse over event, so what I did is to set a new variable IsSkeletal? (boolean) otherwise it would be trying to set the custom depth on both references but one doest exist. I took a screenshot is anyone need to add more types of components. Again I'm a total newbie to scripting so if there's even a better way let me know. ibb.co/LZXqpG1

[@Ninja-Dev]

I have managed to far to update this tutorial (and the previous one) to Enhanced Input, but I cannot get the clicking of the static mesh working. Anyone have any ideas? @The Game Dev Channel ?

[@DJ2punto0]

Hey man, stubborn fellow Enhanced Input user here! I managed to make it work by going to your Player Controller, on its properties you can set 'Enable Click Event' as True. This creates an additional issue, as our fellow guy here disabled the collisions on the actors so they don't collide with the camera, but they don't seem to catch the clicks either!! We need to set the collisions as 'Custom' and on the 'Collision Responses' set everything to 'Ignore' and change the Visibility to 'Block'. Its been quite some time since your question, but I hope it helps!

[@thomaspecheur312]

Hi, the tutorial is great, thank you for doing it. Only one issue, I am having but not if it is due to my setting but I got a long delay or need to click a lot before the blueprint makes its effect. Is is due to by the tick event on Player Controller? Mine is set at 0 but seems to be quite slow and buggy? Am I missing something?

[@Smile1oasis]

Funny thing is that I actually saw the other tutorial which makes the material and clicked this video to get explanation about the nodes used in the material. 😂😂. Anyway Nice tutorial.

[@ChuckDebWood]

Help! I'm not finding the NOT node in UE5? Please advise :) Thanks for making these videos

[@ChuckDebWood]

Found it! NOT Boolean - Again THANKS for making these videos, very helpful!!!

[@thegamedevchannel3063]

Sorry for the delayed response, glad you got it sorted!

[@nothingspeaks]

Great work. Works well for me for objects however i was wondering how you would go about making it do the same on enemies, like diablo for example.

[@MAKRstudios]

Reallllly love the tutorial!!! For those ins UE5, and using nanite the highlight material will not work. Nanite only works on solid opaque materials. And if I understand correctly Post-Process Materials are not considered opaque since it has translucency

[@mathraww]

Hi, my problem is that the highlight part doesn't work. I rewatched 3 times the material part and everything is correct. Same for the blueprint and the post process volume. Any idea why ?

[@jongofett2343]

Hi could i have some help? i just follow this tutorial and when i finish to do it. the Highligh material replace the green changing material dont know how any ideas?

Where do the red and green material come from? I didn't see it anywhere in the first three videos and didn't start with it?

Great tutorial! Question though - How could we blur out the outline?

[@b_m_p_1_9]

Thanks for the tutorials, just a quick question, is there some special way to save the whole file as I go along? I finished this video and the preceding ones yesterday, saved all and when i went back into it today almost everything I had done was reset. Cursor didn't work, camera movement controls were all wacky and the clickable material wasn't working anymore. Have I done something wrong when saving?

[@PowPow000]

Hi, I really enjoyed this. Is there a simple mod to this to make the left mouse button apply 1 material and the right mouse button apply a different material? Thanks,

[@samoverett]

when making the selectable actor component the get owner does not recognise its self as an actor and requires target to have a connection i dont know if this is a change in updates as im using UE5

[@samoverett]

I created a new actor component blueprint and it now works not sure what the difference is

Hi, great job. Don't work for meshes what have translucent materials applied on it? How to set to work for these meshes too?

I wonder. is it possible to change the material of the objects by selecting their surfaces or to select the vertex of the selected surface and get it as data?

[@Bizob2010]

@The Game Dev Channel I'm loving your series so far. I do have a question though: How much of these tutorials would change in between UE4 & UE5? Has UE5 added stuff that would change how you implement all this?

[@pythonmastery4051]

It won't. It's pretty much the same when it comes to the code

[@cactusfloydx5d]

Thanks a lot man. Btw, what is the function of Param0 and Param1? just placeholders? thanks so much for your tutorial, really helped me out. I have nor slept or eaten in days lol

[@aothanhhoa1723]

Nice vid, thank you! To be more specific, pls help to answer me: what's type of template category you used? (Games, Film-Televison.., Architecture-Engineering..,or Automobile-Product Design?). Im using UE version 4.26.2, choose Architecture template category (I'm architect engineer), follow and do the same your vid but my project does not work. I can see my project does not have 2 blueprints CB_CameraController and CB_PlayerController, is that the cause? That Blueprints are automatically generated when choosing template or created by yourself. If that blueprints effect to the result of project and created by yourself, pls help to show me the code of that blueprints. Many thanks!
