10:28 the reason it froze is because you stopped removing it from your array, but still decreased i by 1. The loop then incremented i so you were back to the same element and it kept repeating the loop for that same element.

[Besmudged]

you could randomize the results by varying the gravity each frame between two bounds

16:42 wow hahahaha I didn't exepect that you have a lot of stuff in your studio :')

[tshddx]

At 10:40 it was frozen because you had commented out the array splice but you were still decrementing the loop index, so the loop was stuck on that element forever.

Why does the first one take a different path than the rest?

Love these Dan! Your train will never slow down!!

Hi from Paraguay Daniel. A first year student of Engineering here. great content as always

[TrollingAround]

Amazing how the text/code bind this looks like a "printout" from the 1980's computer magazines... libraries are amazing.

[jasminedeath]

you could just check if greater then you height since even off screen it will fall downwards

[azyfloof]

This is so so awesome :D Penny arcade, basically! Also I think the grid structure with the falling balls is called a Galton Board.
I think the pegs need to be spaced just slightly wider than the width of the plinkos themselves, that'll held stall their fall a bit.

Please do a tutorial on matter.js feature of masking / grouping bodies for collision detection !

Hi anyone can Suggest
hi coding train is there any way to get our Plinko ball in the desired bucket whichever I want ..for every single plink ball and it seems to be random at the same times ...please provide any suggestion or solution

Thanks in Advance

[supLOL]

I am wondering if you would be doing coding challenges in other programming languages? For example, in Crystal programming language?

[YourNightmar]

You're really smart! :P Hi from The Netherlands! :D

[tyreiqdow]

I LOVE all your video's they are amazing and so interesting! Is your job programming?

[FredoCorleone]

Particles trajectory is super consistent in my simulation, do you know why??

[jhn]

Hi @The Coding Train, Is there a way to load an image on to replace the plain colored ball?

[CarlinoGonzalez]

Amazing video series :) Thank you for your coment in my video :)
