Awesome content as ever - still can't believe I've been sitting here all day watching this stuff, being entertained and educated. Just one thing that future viewers might be interested in (I'm sure you know already!) Where you use so.FindProperty( "gridSize"); it's using a 'magic string' that needs to match the property name with no compile time warning if you spell it wrong (which I do constantly due to differing preferences on CasINg!) C# has a function - nameof - that returns the name of a property - so you can use so.FindProperty(nameof(gridSize)); so you get compile time (and IDE) errors if you get the property name wrong!

Hey Freya! I've been following this series for a couples days on my time off to learn the basics of making tools but I have a small issue on the last part making the circle match the ground that I can't figure out where it comes from. I'd be extremly thankfull if you could help. Basically when I make the Poly Line circle it works and I get the desired ground matching effect, but for some weird reason I also get a line from each point that extends towards the center of the world. Ive checked the code multiple times and compared with the way you were doing and I can't for my life figure it out. Once again thank you for your amazing content it has helped me imensely during my projects and gave extremly valuable information!

I have watched so many of your class material! I absolutely love your work. In this class you mentioned using Json. Something I use a lot. But Im still learning and if you ever decide to do a session on Json I’d be super interested to learn all your mad trix. Thanks for sharing your amazing knowledge

Hey Freya! Awesome series! I'm curious, for Flowstorm, is there a reason that your level editor is used in playmode instead of in the editor/sceneview mode? I'm curious what the pro's and con's are of each approach. Thanks!

@acegikmo 3 жыл бұрын

the only reason the level editor is in play mode is because I want my players to be able to make their own levels! otherwise it would be way easier to keep it all in Unity's scene view :)

Could you use for example a scriptableobject instead of the editorprefs to save the grid values, and saving the scriptableobject in the version system so other team members can use the same values? (obviously if the use case requires shared values)

2:29:55 - but, isn't the third normal (bitangent) the camera forward vector, that we also used to calculate the tangent? 🤔 Am I missing something? 😟

@acegikmo 3 жыл бұрын

no, the camera vector is pointing down through the surface, we want one that is flat, pointing along (tangent) to the surface, hence the bitangent

@NeatWolf 3 жыл бұрын

@@acegikmo Yes, I believe I got that... but for some reason I was assuming that since: - we know the A vector (hitNormal) - we know the B vector (camera forward) C (tangent, orthogonal) = A x B --> so also D (bitangent, orthogonal) = A x C. Since D was orthogonal to C that was orthogonal to B, I was assuming that D was the initial camera vector. BUT that's not true since C and D are orthogonal to A, not to B. I guess I forgot about the order. I should probably review the cross product :D Thanks Freya~!

For some reason, neither the Selection.selectionChanged callback or Repaint() are working for me in Unity 2021.1.7f1. My scene view wouldn't update until I moused over it or entered play mode. The callback isn't triggering at all. and even if it did, Repaint() does nothing. not even if called manually. The fix for me was to scrap all the event stuff and just add the following line after the for loop with the DrawAAPolyLine in it. UnityEditorInternal.InternalEditorUtility.RepaintAllViews(); I don't know how optimal that is, but it works. and doesn't cause any focus issues with manual number entry. (Other attempted fixes had that issue) EDIT: The thing you did around the 2:16:16 mark also works. if (so.ApplyModifiedProperties()) { SceneView.RepaintAll(); }
