Thanks for bringing this tutorial! congratulations it's great 🙃✌️

[@armer2001]

Life hack. On line 4 and 5, you don't have to do minus anything. Just set canvas style to display: block.

[@kqnesky_7516]

Masterclass, thank you for all !

[@user-lz2wf5dz2f]

This was a great tutorial. Thanks! How would you tackle more complex shapes like irregular triangles etc.?

[@marienoel1209]

very great tutorial ❤

[@benyuanhu267]

Thank you, I love your tutorial about canvas! Do you know how to draw a line with an arrow between these two objects on the canvas ? You know like a data flow, there is an endpoint on each object, and people can draw a line out of this endpoint and then point to another endpoint on the other objects

[@laurapriewasser5703]

Thank you for this great video ☺️ I have a question concerning the red square. What do I have to do to have a squared picture instead of the red area? And the image should‘t be dropped everywhere, just somewhere in a green area?

[@NiketBahety]

Is there a more optimal approach instead of drawing all shapes again everytime the mouse moves ?

[@satrughnasethisattuk]

Could you please mention what extension you have installed for showing the suggestions? I loved it.

[@kreonovo]

pretty sure it is copilot

which suggestion extension of vs code are you using in this tutorial ??

[@loukiidris9883]

thanks bro

[@dhruvrashiya8612]

I have a question that is eating me away... In mousemove function you defined a new variable let current_shape =shapes[current_shape_index] and then you made chages to that new variable current_shape.x and current_shape.y . But we can see that the chages getting reflected in the main variable shapes , why is this happening?

[@one_bored_dude1798]

a bit late but just found something related to your question in an stackoverflow post so thought I might share :D "My understanding is that this is actually very simple: - Javascript is always pass by value, but when a variable refers to an object (including arrays), the "value" is a reference to the object. - Changing the value of a variable never changes the underlying primitive or object, it just points the variable to a new primitive or object. - However, changing a property of an object referenced by a variable does change the underlying object." Here he passed a reference to an shape object and just adjusted properties of that object, therefore the original object was affected aswell. If he created a new shape with the basic properties of the object instead, changing that shape would not affect the original object anymore.

Hello, make a tutorial on how can we implement something like a circle in the center of the screen and a line following the cursor when its close for example if cursor is 50px close to the middle canvas then connect cursor and canvas with a line when the cursor is 50px further then make the line dissaper

[@petarvitanov2297]

Hello, would this work well if you have multiple objects? And what if objects are images ?

[@aakashinfo949]

Veri nice sir thanks

[@ilyaserebryannikov858]

i want that gist

[@Xlorate]

Good work, my shapes failed to move after subtracting offset_x and offset_y, I assume js did not recognize them as numbers?

[@migliorelli]

@@BananaCoding I have question for you broo, Its normal to breakdown while you dont know how to fix your bug.? then can you make a video how to put map tile and sound effects when you make a game (sorry to my english )

[@rajkumar-gh4tq]

source code please

[@alejandro-qm6vl]

if you just want the code then it's alright, but if you actually wanted to learn anything then this is not the best video for you. you were getting the explanations alright at some point, then down the line, it looked like we were just watching you code over your shoulder and mumbling the explanations. you were typing too fast, ill look for a better tutorial. I still don't understand how some of the mouse functions worked. but hey it just works I guess.
