Hi! I need to make a slot machine effect So a running light over 4 outputs the goes slower and slower I thought to do this in a loop but i cannot get the delay working. for example i did this: msg.payload = "test1" node.send(msg); delay 1000; msg.payload = "test2" node.send(msg); delay 1000;…

Hello, There is no native delay or wait function in javascript so this approach will not work like it would in c or python. You most likely will have to approach it differently. Some ideas I have are you could try move the delays outside of the function node and use something like the trigger or de…

Another idea [{"id":"949f8f0b.827c38","type":"tab","label":"Delay","disabled":false,"info":""},{"id":"e68e112c.5b28f8","type":"inject","z":"949f8f0b.827c38","name":"Go","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","…

I think this approach although very simple might get messy very quickly if you try to apply it to more complex examples which require a longer loop and maybe although a variable changing delay which I think is what @RogierQ will need for his slot machine but it definitely is a quick workaround :+1:…

[image] JGKK: quick workaround Very quick solution, indeed. But for 3 or 4 light bulbs it's simple enough. For multiple bulbs, not applicable.

Thanks for your ideas! Only thing is that in the examples the delay is static, but the delay needs to get longer after every step. so it starts fast and stops slowerrrrr I cannot set the timing parameter with a external value from the script

Take a look : [image] Delay node with variable delay General Ok, I made a big mistake with my reply. I made it. Not you. The msg.delay needs to be sent with the message. So: If you send msg.delay 3000 then send msg.payload Hello through the delay node as is, it will…

You can set the delay by adding a msg.delay property to the msg you send from the function node and setting the delay node accordingly. Here is the same example with the delay being set from the function node and getting longer: [{"id":"5331bb12.a5ac24","type":"tab","label":"Flow 3","disabled":fal…

You should be able to simulate a delay (without blocking Node-RED from processing other things meanwhile) by using async/await: async function delay(timeMs) { await new Promise(resolve => setTimeout(resolve, timeMs)); } msg.payload = "test1" node.send(msg); await delay(1000); msg.payload = "te…

[image] ristomatti: await new Promise(resolve => setTimeout(resolve, timeMs)); i was just recently studying about promises and the syntax is to short to fully understand the resolve but shouldnt that be return new Promise(resolve => setTimeout(resolve, timeMs));

It might not make a difference in this case. As the async delay() returns a Promise. The Promise is resolved when the part of the function that awaits the manually created promise to resolve (after the timeout). But if both work, your suggestion would avoid rhe second promise layer. TBH I just did …
