i think this is math

[crimson saffron]

if i get a line from the origin to the target, how do i get the rotation from the start that faces towards the target?

[median pier]

Ugh, been a bit since I’ve done this. Are you referring to how you can get the line to actually connect the 2 (e.g. with a part), or does the line already exist (with e.g. a raycast)?

[crimson saffron]

im trying to make a type of line

then

i want the rotation of the line from the origin

as if the origin was rotated to the target

anyways i gtg

be back in a few hours

[tame glen]

you use math.atan2(Y, X)

[median pier]

Alternative, subtract the 2 angles from each other

[tame glen]

lol ig that works, sounds janky but kinda smart

[median pier]

Why is it janky? You change the angles “origin” over from world space to object space basically

[tame glen]

I've never seen that in the programming world

[agile wolf]

cframe.lookat depending on exactly what you're trying to do

[tame glen]

yeah if you only have the positions

[agile wolf]

cframe.lookalong if you only have a starting position and direction, but usually you'll have 2 positions ;p

[median pier]

Somehow he has the part already rotated but needs the axis

I mean, it would also return the correct angle, yet I wonder how he got the original angle in the first case without… well, having said angle

[tame glen]

oh wait I know why subtracting is bad, its cause it tells you how much it is rotated relative to the other rather than the actual heading in the world

Hi I'm back for a lil

I just read the thread

Just wanna clarify some questions

I don't need to make the line, just an example, I'm trying to go from 2 positions that is already known, and i wanna get the direction of it, like how if i look at a window that's the way I'm facing, i wanna see if i can get that info from just 2 positions

Also

When I'm back

Again

[crimson saffron]

I'll try this

[crimson saffron]

im back on pc
