What's wrong in my code?

What's wrong in this code? This code triggered only once.

Well for starters... There is no loop.

You need a repeat or for condition to make a loop.

A loop gets completed on a single tick. Your i value isn't getting updated until .2 seconds later.

Wait only delays actions from happening, not your events from running.

Your for each loop is still nested under a function, which is a trigger, so depending of what you need, you need to use a loop that will trigger this function multiple times, something like every X seconds for example

What exactly are you trying to do?

If you want to change the opacity of sprites one by one with 0.2s delay, remove "For each" and add recursive function call as the last action in the function (after "Add 1 to i").

The function will call itself until there are no more objects with id=i.

dop2000 Yes I want to change opacity of sprites one by one with 0.2s delay.

and I didn't heard word "recursive" before.

I followed your instructions and called function inside the function and after that added 1 to "i" and it worked. I don't know how it working but its working. I will read about it. I did check in manual there is no Recursion word used.

Thanks for help
