Incredible series as always! tons of things to try in my projects!

[@taguetrash]

That Roomie script looks amazing for quick mapping, makes me want to make something similar..

[@mailmaxxxx]

Thanks so much for this series! I confess to being completely lost in Ep 4 because of the refactoring, but overall I've learned so much :)

[@TheRabidCabbage]

1:05:20 Oh no. Thor has finally discovered your weakness! xD

[@chirantansarkar8888]

you rock freya thanks for this many would be helped and will be getting help for so long i wanted to be a game dev too but ended studying economics

[@Patrick-pu5di]

Freya being GOATED for 1hr47mins straight

[@genelee2050]

this is awesome tutorial & 'let's do'' stuff. thanks for the patience

[@ucanhle3092]

you're awesome! please keep making videos! thanks

[@CosmicComputer]

thank you for this Freya!

[@mongmong4519]

Big Thanks!

[@kevin1a2b3c]

Thanks for the tutorial! But may I ask how do I get all spawnPoses by tangentToWorld? (the part at 2:38) I can't figure it out.

[@alfredmakes]

Old comment but for people who see this in future, you can replace the hit.point, hitNormal etc. by multiplying basis vectors by the TRS matrix:
Vector3 origin = tangentToWorldMatrix.MultiplyPoint3x4(Vector3.zero);
Vector3 normal = tangentToWorldMatrix.MultiplyVector(Vector3.forward);
Vector3 tangent = tangentToWorldMatrix.MultiplyVector(Vector3.right);
Vector3 bitangent = tangentToWorldMatrix.MultiplyVector(Vector3.up);
So then when you're drawing the green basis vector, for instance, you get:
Handles.DrawAAPolyLine(4f, origin, origin + bitangent);
Note that since the origin is a point you use MultiplyPoint3x4(), but the others are direction vectors so you have to use .MultiplyVector() instead~

[@Parkathor]

Crazy informative series! Ngl tho, the change to tangent space in the beginning did make things more confusing.

[@user-kt8rw7wu7o]

nice tutorial ) have you git repo? i would be nice to read code examples

[@philipZhang86]

Thank you so much~~~!

[@mirkoson]

Hey Freya, I've been enjoying this series of tutorials, but I got lost on your refactoring since you didn't show how the GetCircleRay and DrawCircleRegion work with the Matrix implementation. Any chance you (or someone around here) could clarify that part? Thank you!

[@alfredmakes]

Hi, just replied to a similar comment in case you are interested~

[@mirkoson]

@@alfredmakes thank you, sir. 😊

[@justloveandpeace4010]

amazing tool it is.

[@Fortu440]

but we who watch the video on youtube can´t see all the changes made in the script and therefore can´t keep up with the rest of the project. :(

[@superdavisdon3791]

Coolio! :)

[@smstitan6400]

It's really sad, so much effort
Very less views, but these videos really help the ones particularly searching for them
Or give some interest for someone like me

[@adgd]

I was following and when you showed up with a completely rewritten script I completely lost my bearings and gave up on following the code :/ I even tried pausing the video at times to copy the re-written code but you don't show everything you changed y.y
Amazing series anyway, loved it!

[@acegikmo]

here's the script, I think!

@@acegikmo Thanks!

[@patrevizani]

@@acegikmo is there any recording/explanations regarding the changes on the script in the link vs. the script in the end of the video? On the video you use EditorWindow and on the link you use EditorTool, thanks in advance!

[@acegikmo]

@@patrevizani I forget! it's such a long time ago now unfortunately
