Finding if point is within surface-light like area

[sly fog]

How can I find if a point is inside the red box? @me if you need more info (or better pictures lol)

[sly fog]

I shpuldve added this, however you are able to edit the angle pf the box in radians. The box isnt a literal object nor mesh

Think of a surface light, and detecting a point within the surface light.

pretty sure region3 is deprecated

[coral juniper]

just use the point.Position.[Axis] > Box.Position.[Axis] - Box.Size.[Axis] technique for all the axis

[coral juniper]

all the workspace region3 methods are deprecated

it is replaced with workspace:GetPartsInPart() workspace:GetPartBoundsInBox() workspace:GetPartBoundsInSphere()

[sly fog]

would that work with a custom angle though? The box protrudes like a surface light

Like the red/yellow box, you can change the angle of it

[coral juniper]

oh no

wait whst

that custom angle is just the perspective

[sly fog]

? Its like a surface light

[coral juniper]

hmm

so a point in a polygon?

[sly fog]

Somewhat, let me find a picture

[coral juniper]

ohhhh

check if point is in surface light region

[sly fog]

I shouldve sent that picture first, mb

[coral juniper]

ok

well the shape of the surface light is called as a frustum

so google "check if point in frustum"

and try to solve it yourself

[sly fog]

Oh i didnt know that, thank you

i was looking up random shapes oml

[coral juniper]

lol

i just remembered the word from view frustum

which is the camera's frustum

[sly fog]

ah like fov

[coral juniper]

ye

there is a thing called frustum culling also

which removes objects if their not in the view frustum

[sly fog]

Oh i think ive heard of that, like “unloads” anything not in view. performance thing
