player | A playlist abstraction layer on top of SoundManager | Media Player library

You need to map your array and render options inside your select like this:

Here, you have two different problems :

First the movement is not working because to differentiate the keys, you use event.type to compare where it should be event.key. Try with for example :

This issue appears to have resolved itself. I suspect it was a bug in the iframe api or maybe the youtube backend which has been fixed by the youtube engineers. So iframe team, if you see this, thanks!

Most likely the Vector3 format is more efficient than a string conversion for storage. Each number in the Vector3 requires 4 bytes to be stored because each number is a 16-bit float. By converting the Vector3 values to strings, additional bytes are required (each digit you add requires one byte since a character requires one byte). If you need to store a Vector3 as a string I would suggest using the method below.

For anyone who would like to learn how computers can store such a wide range of numbers in only four bytes, I would highly recommend researching the IEEE 754 format.

Video that explains the IEEE754 Format

You can use the string.pack and string.unpack functions to convert floats to byte arrays which can be sent as strings. This method will only require 12 bytes (12 characters) in total when sending data and has around 5 to 6 decimals points of precision. While this method may only save a few bytes it will allow you to send/save far more precise numbers/positions.

I have checked an example again and it works. The one reason that it doesn't work it's startSeconds property. Somehow, when we add this property it stops to autoplay the video. But without it, it works well.

The duplicate not being removed. Nothing prints

You print something in both branches of your conditional statement. If there is nothing printed that means the loop does not run a single time. That means that player.Backpack:GetChildren() returns an empty table.

As Instance:GetChildren() will always return a table, seeing an empty table means that Backpack does not have any children.

Collision detection depends on your needs.

• Bounding boxes are simple and can detect if the x, y edges of each object are not within one another. This is fine for fast moving games and things where you don't necessarily require point precision.
• Distance vectors are also simple and perfect solution for circle collisions. They calculate the difference in distance between two objects according to a radius prescribed with the hypotenuse of distX^2 + distY^2.
• Compound bounding objects are harder to calculate, especially for concave areas on objects of arbitrary shape. There are too many notable and novel approaches to collision detection beyond these to remark on here.

They're also increasingly complex depending on things like variability (if they're deformable objects, if they have particle seams, etc and 2d vs 3d object collision can be vastly different worlds as well. There are tons of articles, but I'll post one with implementation here

You need to add the seconds of cooldown you want on the spawner when you declare it too, E.G spawnCooldown = Time.time + coolDownPeriodInSeconds;

You also need to set spawnCooldown to be a float, which stores numbers. Currently you have stored it as a bool, which only stores true or false values, and therefore cannot be compared to Time.time further in the code.

Lastly you are missing the closing } character in the if block

What is happening currently is you are doing the following:

1. Setting spawn Cooldown to be the current Time
2. For every frame after that, checking if the new current time is greater than the old time you set as spawnCooldown. Since it always is, the code will then run through the spawn script.

If you change it to

In a non-SwiftUI situation, I'd normally recommend making player an optional and loading it later, but, as you've probably discovered, you can't make an @ObservedObject or @StateObject optional.

I'd recommend refactoring AudioPlayerAV so that it does the important work in a different function than init. That way, you're free to load the content at whatever point you want.

For example:
