Why sometimes some events don't work?

We need to see your issue somehow. Otherwise we can't help

Fine, I will send it with a video. wait, I want to go to my online school.

Add "Trigger once" condition to event #13 on your video.

Seriously, you could have saved yourself and us a lot of time if you just shared your project file.

Well, it do work, but only when the opening of the puzzle, and the other events after the opening doesn't work

It's probably a good idea to read through this, it really helps to understand how the events work. Especially the "events run top to bottom" is an important part that might help understand the issue.

Again, without the project file it's impossible to help. If google drive doesn't work, maybe try wetransfer.com (just email it to yourself and post the download link)

Just try putting a screenshot of the broken code.

Here's a quick fix. It's by no means an ideal way to do things but it should get you started.

What you really need to understand is that events like this run every tick, as in if the game runs at 60 fps, these events will be executed 60 times per second.

And a similar issue caused the wrench thing not to work, as it would instantly set the chain visible again after it was set invisible by the wrench.

I simply rearranged the first thing so it's now a sub-event of pressing the button. As such, only when you press the button it will check if the count has reached X. As for the menu, I simply added a "Trigger once" to avoid constantly overriding it.

Ideally you'd handle most of this quite different, but that's for another day.

Also I deleted the music in my fix, 23mb for just one song :V

It's great how determined everyone is to help someone out!

Well thank you so much! Well, I cloned the fix in the real project cuz it's saved in R272.2 though :V
