I'm not sure what you're saying

#

Specifically, what is the for loop faster than???

ember smelt Dec 11, 2022, 4:37 PM

#

When there are multiple elements in an array, it updates faster, as seen by the example Gifs.

fringe tendon Dec 11, 2022, 4:40 PM

#

Your code doesn't really tell me enough to say exactly what's happening. But with 10 items in the array you're gonna call update 10 times, if there's only 1 item you only call update once.

ember smelt Dec 11, 2022, 4:40 PM

#

Yeah, and is there anyway to seperately update each one?

fringe tendon Dec 11, 2022, 4:41 PM

#

No idea. You would need to share more code.

ember smelt Dec 11, 2022, 4:41 PM

#

ah my bad

#

What code do you need?

fringe tendon Dec 11, 2022, 4:41 PM

#

No idea. It's your code and I haven't seen it.

ember smelt Dec 11, 2022, 4:42 PM

#

It's really just the W3School Flappy Bird example code.

fringe tendon Dec 11, 2022, 4:42 PM

#

No idea what that is or where to find it.

W3Schools offers free online tutorials, references and exercises in all the major languages of the web. Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more.

#

It is that one

#

I don't see why any of that code would be sped up by adding more components. It already adds new components over and over.

#

The loop that I've underlined is the one that I used

fringe tendon Dec 11, 2022, 4:54 PM

#

Did you change anything else?

ember smelt Dec 11, 2022, 4:54 PM

#

When I got rid of myObstacles[i].x += -1;, it started going faster

#

forgot to mention, I have my own moving part, but that's not what is making it faster.

#

I debugged it, and it is the for loop that is making it faster

fringe tendon Dec 11, 2022, 4:57 PM

#

What else did you change?

ember smelt Dec 11, 2022, 4:57 PM

#

I believe that's it

fringe tendon Dec 11, 2022, 4:58 PM

#

So the gifs are the result of changing that one line?

ember smelt Dec 11, 2022, 4:58 PM

#

I got rid of the line, I have my seperate moving system, but what I believe the problem is that it is being updated faster.

#

So my question is if there is any way to slow them down

fringe tendon Dec 11, 2022, 4:59 PM

#

Ok, so you did change stuff. I can get rid of that one line too and nothing goes faster.

#

So some other change you made is causing things to go faster when you remove that one line.

ember smelt Dec 11, 2022, 4:59 PM

#

The line makes it move by itself, however that's not what I want anyway.

fringe tendon Dec 11, 2022, 4:59 PM

ember smelt So my question is if there is any way to slow them down

I don't know because I don't know what changes you made that would cause it to go faster.

#

Makes what move by itself?

ember smelt Dec 11, 2022, 5:00 PM

#

The line makes the component move by itself, my code makes it so you choose where it goes, that is not the problem though, I debugged the code manually and found out that the for loop is the problem.

fringe tendon Dec 11, 2022, 5:02 PM

#

The components are the green lines in the W3C code. You don't have the green lines so I'm not sure what's moving by itself.

Again, removing that line from the W3C code doesn't result in a speed up for me. Therefore some other change you made must be causing the speed up when that line is removed.

man, forget about it, i'll just try myself

#

thanks for the help

#

Sorry. I can't help if I can't replicate the issue. No one would be able to help you given the information you have shared thus far.
