Hello and welcome, I am your Code Monkey and here you will learn everything about Game Development in Unity 2D using C#.

I've been developing games for several years with 7 published games on Steam and now I'm sharing my knowledge to help you on your own game development journey.

I was looking for a solution to this problem ...and I came across this video. Many thanks ! God bless

[MikeMinneman]

This is fantastic and should be part of the official unity documentation since it's a bit hard to follow.

Thank you, I'll use this to get data from BLE (Bluetooth low energy) sensor to unity game using the Javascript WEB-BLE API.

You are the realest MVP 🙏. Thank you.

Please make a course about how to create a complete game in unity on udemy 😊 i think your subs will love to buy it

Can you do user generated content with uploading

[joshreaver]

Sorry to ruin the '69' comments by adding another but do you have an updated version of this that would work with the new way Unity creates WebGL builds as it now creates 4 files instead of 6 and instead of Build.json its a .wasm and using the script in this video says 'cannot find unity loader'. So I assume there must be a way its just not whats in this video.

the PHP one is messing me up. Im trying to pull information from a mysql database with PHP and need to POST to the PHP. Normally this is no problem in anything except WebGL. None of the sites i have been to seem to have a good concise answer

"I used your method, but the button I wrote in the HTML cannot trigger my Unity function. I have tried many times but still cannot make it work. Can you please tell me what I did wrong?"

[jatingoel]

Hi, I want to pass userId in webgl build whenever user login in website so Unity WebGL iframe get that userid string value in my unity code?

[merabet.faycal]

Can you please explain if any have an idea about this error am getting in the log console
SendMessage: object JavascriptHook does not have receiver for function "function Name"

even tho the function names are identical in both c# and js scripts AND am passing string value

[jackgunderson]

Awesome video --I'm able to make the changes to the colors no problem, but when I try to pass a number or a string with the function I get "Cannot read properties of null (reading 'Send Message'). Any suggestions? I've tried on my own project, and then used your exact project files.

Please create a video for setting up and using Firebase services (Auth, Realtime Database, Firestore, etc) with Unity for WebGL. The Firebase SDK for Unity doesn't support WebGL however there are old videos (uNicoDev) that show how it can be achieved, that are now outdated and no longer work.

[dariogarcia]

how would it be the inverse, receive data from javascript to unity?

[nicolasportu]

Hey! How to sync float range slider from js to to Unity? Thanks

[LouieLu-pzbj]

I'm currently trying to create a project using this method. However, I can't understand how you manage to run Unity and html on local host, especially on the same web page. So I don't really know how to test the codes like the video described. Can you provide a video or a link to this kind of tutorial?

how to save file into player local machine ? in webgl

[돌림정]

is it possible with c# winform program without java/php?

[RobertGercia]

Hi, I am new to game development. Just wondering, between Unity and Unreal, which is possible to do such task as this: User input email address, on submit button, the game capture screen shot and send the image to the email. If there such beginner friendly tutorial on this, please take us there.

By the way, great content as always. Everyday I learnt something new.

Can I send data back to the website from Unity? I want two-way communication so I can ultimately access a MySQL database and save data. I know how to do the database stuff in PHP but we need two-way communication. Can we send json back?
