[@CarlMahnke]

Didn't expect JS to be this performant! Excellent Job!

[@fredesch3158]

1:10:35 Ok, I may be looking too much into it, but the fact the effect ends up being so good is because intentionally or not you're imitating most of forces we interact in a daily basis, making the force decay with the square of the distance, electro-magnetic, gravity, all of them act like that, by not taking the square root of the distance on that pythagorian theorem you made your force also decay with the square of the distance.

[@brad7957]

An excellent course. I love that you let beginners know that not understanding some of this is fine and "doesn't make you a bad developer" - this really helps with imposter syndrome. Thanks :) As a full stack developer with 4-5 years of experience but no math education, this was probably a 7.5/10 for me. I've never used atan, sin or cos in code before.

[@Frankslaboratory]

Hi Brad, thank you for this feedback, people think you have to be a math genius to be a good programmer, I don't think so. Trigonometry is very useful in creative coding, I use it all the time, but the concept of atan, sin, cos is quite difficult for most people. Didn't know we had experienced full stack developers here, very happy to hear that, thank you for sharing and commenting, nice to meet you.

It becomes easier as you build more projects. You will kinda learn how to tell the computer what you want it to do, in it's own language of math. Good luck with your coding studies :)

[@nachopuma13]

May i humbly suggest a small improvement? On 1:13:00 , when you define the pushing force from the mouse i notice the following: - you calculate the force modulus using radius over distance, this gives you a linear force field, and i think using distance squared could've given a more physics acurate effect wothout much performance taxing. - when you then use atan, cos and sin, i think there is no need for such functions, since the signed dx,dy coordinates that you had already calculated, multiplied by the forceodulus could give you the same results, without resulting to the trig functions. That it. Also, im writing this as soon as i saw it on the screen, maybe you fixed it later or something, in wich case, ignore this message 😅. Thanks for the content, i just found your channel today and im vompletely hooked. Greetings from 🇦🇷

You can use script defer to avoid window load and you can asign base64 imagen to const and load directly to drawImage

[@EllisEnobun]

If script is at the bottom of the body tag, there is no need for the "defer" flag, since the DOM will parse before running the script. However, to ensure that the site loads "heavy-lifting" stuff like images, while the html is parsing and "before" javascript code runs, the `load` event listener is called.

Hi Frank, Thanks so much for the great tutorial. Is there a tutorial or a section in one of your videos that shows beginners how to position this type of canvas anywhere you want including the Hero section? or incorporate it into different projects altogether? I'm having a tough time incorporating this into a project as something is making the hover effect not work and the image display twice. Any tips you may have will be most appreciated and helpful ... thanks in advance!

[@Frankslaboratory]

Hi, canvas can be positioned with CSS as any other element, you just have to be careful when you do that, about resizing it and about mouse position coordinates and account for that. If canvas is not full screen you can capture mouse coordinates using offsetX and offsetY properties on mouse event object. To put some CSS text in front of canvas you can give that text pointer events: none to make sure it doesnt interfere with mouse events on canvas, there are a lot of small things like that, I don;'t always repeat all of this in every video but I covered all of this over time in the projects

I mention how different settings affect performance as we write the code, it really depends what you want to achieve. I would suggest just a simple logo or a small image, not a massive full site background using this. To make this effect bigger there are very good advanced optimisation algorithms, that I didn't cover in this video. We could use quad tree to manage some of the calculations in a more modular way. I might do an advanced video on these techniques if people are interested later.
