In need of a good vector math tutorial, and i think i found a bug

Hi!

So I’m working my way through the tutorials and examples with a decent result. I am (as i stated in the introduce your self post) a Lua newbie, but not with programming so I think I’m starting to get “a hang of it” (some of it atleast).

One thing though is giving my head a lot more grey hairs and that is vectors, ok i get the concept but I would really like to know why… so instead of just copy/paste stuff and not understand why .dot / quaternion/some other really cool math expression, does what it does. Do anyone have a simple “vector math for game development” refresher I can read :slight_smile:

I have used some game engines in that past, but most of them have had a “I hold your hand when you do rotations, colliding and scaling” mindset… Even though that might be more easy, we all can agree that if you played one unity game you know how the next one will handle gravity for example.

But i really like Defold. Beautiful editor, Lua seems really nice… Great work…

One last thing…

Perhaps this is well known, but every time I have a “create something new” window opened Defold crashes when you switch between windows.

For example - I did a tutorial and created a new collection, when i cmd-tab to safari to see what I should name it, Defold crashes.

Thanks in advance.

Edit changed the title to be more descriptive.

I think we’ve had links to some vector math and quaternion tutorials on the forum in the past.

As for the crash: Are you using Mojave? Did it crash while you had a popup open and switched program?

oh, I should search better then to see if I find them.

Yes, Mojave. Exactly, and it doesn’t matter what popup. It could be a new go/atlas to a rename popup.

For me it is always the best to watch YouTube :smiley: Here is a nice compendium too.

P. S. I would like just to ask if you could please edit the title to precise it a little bit? :smiley: It’s just too general, so it would be great for the people in the future :wink:

The Mojave crash is a known JavaFx issue. There is a known workaround mentioned elsewhere on the forum.

From a “glass half full” point of view, it have given me the good habit of saving more often.

But I will search for the workaround. Thanks.
