Hello world ! I got a question: I’m developing a widget that sets my light temperature and intensity, its working, but i would have to turn on and off my light so it will update. And would be better if it react in real time. [image] I’m triggering it by line trace by channel. So on first click …

[image] This creates a timer then immediately kills it. [image] [image]

[image] This is to call an event every (number of seconds) when you hold down the mouse, and stop calling when you release. Remember to set your light to dynamic.

Hi, thanks for anwsering. But i think that your tip didn’t work , guess i must did something wrong. Where would I fit that timer ? And where do i set my light to dynamic? Is it in details ?

1- Light can be set to Movable in the details panel under transformation, this makes it Dynamic. [image] 2- Set the timer when you want to begin the interaction, so if you’re using a slider with the left mouse button, use it on button is first clicked, but remember to only trigger it once, not whi…

Sorry, I’m realy new to unreal blueprints. [image] For sure i did wrong, but I didn’t understand how to set to on button first clicked, as It’s trigger by this interaction, and its a line trace. [image] [image]

@GuiHey Could you print the length of this array? [image] What do you get?

I think the getter works fine since the lights are turning on, right? But the light changes when you begin the interaction, so when he begins an interaction it applies the previously cached values. Am I misunderstanding?

No, what you said worked fine! Lights are updating in real time, but now they are not turning off. I guess i called the “completed” to my other bp in a wrong manner, would it be by blueprint interface ?

[image] SpectreKelevra: Am I misunderstanding? I am, for sure. If I do what OP does in the very first pic, it works very much as expected: What kind of lights are we talking about? I used default spotlights. I probably did not read the thread carefully enough.
