In this video we take it a step further with our blueprint actor streetlights and I cover how we can set them up to be controlled by a keyboard input. The specific streetlights are more difficult because they require not just the light to be toggled but also multiple material changes to get the look correct!
Hope you found this helpful and let me know down below if you have any questions or things you would like to see covered in a future video!
Hey Peyton, thanks for the video. I'm trying to use this method to turn on lights on a vehicle -- the lights start on the vehicle, I can turn them off, but can't seem to turn them off. To turn them off I'm calling the 'Set Material' and using the Element Index for the 'On' lights -- and for the 'Out 1' setting of the MultiGate I'm calling the 'Of' light texture (that actually doesn't start on the mesh). But I have a feeling, it doesn't actually swap the material, more so enable/disable it - so when I try turn them on, it does not have any of the 'Element Index' to look up.
Hey man!
How did you do the fog so the light is visible all the time and not only when it hits a surface? Could you help me? :D
Is there a way to make a delay on the lights so they turn on in a sequence? For example, a warehouse with 20 lights and when you push the button the first light turns on, and then the second, and then the third and so on - is there a way to achieve this with blueprints in ue5?
I am not the best with blueprints, but on a whim I would say to stack the lights with a delay. One light, then a delay with a new light and so on.
Nice ! But how i can save/use the Lamppool and the Light for example a procedural City ???
In what way? If you mean you are creating your city procedurally then it would have to be implemented into the same sort of technique that you are using to actually build out your city as well
@@PeytonVarney Thanks !
May I know how you made the lights have that triangular shine on the streets without scattering everywhere? been trying to do that with point light in UE 5.
Spotlight will be a much better starting point for you. Point lights dont have directionality by default and will go outwards in all directions. Spotlight will already have the direction implemented!
@@PeytonVarney Much Thanks☺
Awesome job breaking down how to do this, Peyton! Really makes for some cool narrative opportunities with level design and great to see how you work within the blueprints! Excellent work!
It Does work but not in a build or Standalone Game.
I did not recommend putting it all on tick. This will become a costly action, it is better to switch to the interface or the dispatcher
Appreciate the insight, will try to switch it over if I expand upon this further!
Hi Peyton. Great video. I was wondering, is there a way to press F to turn on and off lights, but also have a button in a widget that does the same thing? I can't seem to figure it out beyond creating the OnClicked Button in the Widget :(
Thank you for doing this. I spent the last 6 hours looking for a Unreal Engine tutorial that would show me how to find if a key was pressed. I spent 9 years being a Unity Developer and I finally decided to try Unreal Engine. Thank you Peyton Varney, I was so close to uninstalling unreal engine and going back to Unity3D.
Glad it helped you and kept you from giving up on the engine. I love a lot of what the engine has to offer and of course it is difficult sometimes to find what you need but hope you enjoy using it. let me know if theres anything else youd like covered as well!
👏👏👏
