Well usually when i do cframe stuff it takes so much tinkering and messing around
what's the best source to learn the basics of linear algebra to do some good and intentional cframing, |

"Highschool?" >Rarely.
If you're a quick study, I find: Linear Algebra and Its Applications by Gilbert Strang while brief, to be an excellent reference.
If you need something more solid: Linear Algebra Done Right by Sheldon Axler
*Note these texts are available by binging libgen (first link) searching the title, and downloading from 3rd mirror. Google will not show you libgen.
Now, if you want to just cut to the chase. Learn basic properties of matrices (i.e. multiplication & inversion as well as order of operations). There are quite a few different sites that'll do this. Khan academy has some decent tuts.
Also, you should understand that a standard CFrame (3 numbers of which present a position vector and the other 9 of which represent a rotation matrix) populate a 16 element matrix like so.
[X.x Y.x Z.x P.x] [X.y Y.y Z.y P.y] [X.z Y.z Z.z P.z] [ 0 0 0 1]
where X, Y, and Z represent the local axes of the object as seen from world space and P is the objects position in world space. |
