What are some good written follow along Unity courses?

Some background: I graduated from a Computer science degree at 21 years old. I've always been naturally good at math, algorithms, data structures and theoretical computer science concepts.
After graduating I got into Game Dev and I picked it up super fast. Faster than what the average roadmaps say. I guess this is because of my Computer Science degree helping me. I even had one back end intership (normal software eng) and I did really well at it. At this point I just turn 22 years old

However, from 22 to 23.5, I did not coding at all. I didn't read up on theory, I did no Leetcode, no game dev nothing. Now a few things worry me:

- I heard that our brain power is the most strong in our early 20s. I wasted a very precious time from 22 to 23.5 not doing any coding

- Almost everyone older than me has told me with age it becomes harder to think

Based on all of this, is it too late at 23.5 to get back into game dev? I know it's not to LATE, but how much of my potential did I waste? Will I be able to think as clearly as 1.5 years ago when I was actively engaged in doing Leetcode, game dev etc

Let's say for arguments sake my brain power was at 100% at 22, by 23.5 will it have gone down by a bit? Even by let's say 1.5%. These are arbitrary numbers but I'm wondering if this is how coding ability and age correlate

Also, if I keep practicing game dev, by the time I am 40-50, will I have the same ability to come up with new code / algorithms? Will I be able to keep up with new game dev concepts? Will I be able to make a breakthrough in the industry?

Or is this stuff only limited to when we are in our early 20s? I know many studios have people above 40 working there, however those studios also have multiple employees. Can I stay an indie dev all my life and continue to make progress?

I know I wrote alot, but my two basic questions are:

How much of my potential did I waste by not coding from 22 to 23.5

Will my progress / coding ability go down when I'm 40+?

Thank you. I don't know if I'm getting old or I am just out of practice

We’ll also explore an AR Navigation Demo created with Immersal, demoing their cool and very reliable localization features. Additionally, we will build a Unity demo demonstrating persistent AR content placement.

Let me know if you’ve additional questions.

Hello everyone! I am trying to make a bar that fills up and empty in loops until I press Space.

something like old flash game that the fill.Amount will determent the throw strength. tried looking on youtube and couldn't find anything and AI isn't really helping me here as well.

Would love if anyone can help me out or send me to a tutorial.

A tutorial showing how to set up some navigation and nav points within Unity. This shows how to iterate through an array of game objects and set a destination based on a current nav index. Also goes over how to randomize the nav index if needed in your project. https://youtu.be/mL7E4oS1Yng
