How Isometric Coordinates Work in 2D games 

Thanks, the inversion was tricky to implement from the formula. The one thing I added was rounding the results from to_grid_coordinate(), but besides that it worked like a charm. Thanks for the interesting video. EDIT: spoke too soon, for some weird reason the Y from to_grid_coordinate() is off by 1, and I don't know why. I can hard code the fix, but it's ugly. Also, the multipliers on the code are all 0.5 and in the video some were 0.25. It works but the mismatch is disconcerting. I tried to change the numbers to match the video and the results are crazy.

@@rafaelrosafu If something's stored as an int somewhere and it's being divided, it will be rounded which could explain the error consistently being off by 1

@@metallsnubben good point, I'll double check. thanks.

It now has 101K views

@@rafaelrosafu Hmm not sure about the Y being off by one, but the 0.25 is after halving the iy and jy (to account for sprite size: 0.5 * 0.5 = 0.25). In the code above I left it unsimplified for clarity, but I suppose in doing that made it more confusing haha.

Well said!

I agree!

That's awesome, so glad it helped :)

I especially value such vibeos!

While remaining entergaging (/hj) as well!

(the /hj is the ironic use of the term, but the genuine meaning behind it)

(tho yk. ik that effective educational content is also entertaining haha. it's also very pretty~)

​@@marianmotorina chillax dude I said "i knew all this" to emphasize that I still got something from the video, even if the concepts were familiar. this is a compliment

@@marianmotorina ratio bozo

@@kingbroseph9773 lol he really did go for it after a literal year

Thanks, and here I am amazed it's even getting a hundred views :)

@@JordanWest you deserve much more than that

I’m still amazed I’m sure it will blow up at some point

@@UndeadAlv f-four hours ago??? Is that a /j as in u came across it and it had 37k views as it did for me (and abt 1/10th as many likes)? Or did it seriously explode in _four hours??_

@@foul-fortune-feline well, we are all here right now

That sounds fascinating, I wonder at what point is it easier to just go to 3D? I guess there's always a tradeoff, especially if you want hand drawn sprites instead of rendering triangles.

this just makes me think of what a nightmare chris sawyer must've had with rollercoaster tycoon

In this animation the sprites are simply rendered from back to front, left to right. Often you can get away with sorting by the screen y coordinate

@@JordanWest oh *nice*

Thanks for the kind words, glad you found it helpful!

I love that your search perfectly matches my video :) glad it helped!

Ah good catch, thanks

you're the type of guy to correct Albert Einstein, and be right

Thank Matt, do you mean converting the math into code? Or going deeper into the process of building a map from isometric coordinates?

@@JordanWest Usually people mean turning it into code. Sometimes its easy to follow a concept but applying it can be difficult. A small tutorial example of turning this into a script and how each part works would be good
