camera.set

function#

Sets the camera shot: follow (the player's own camera), fixed at a position, orbit around a subject or track a subject from an offset. It blends from the current view over duration and replaces a running move.

camera.set(target: Target?, options: { … }) -> ()

example

camera.set(player, { mode = "orbit", subject = player, distance = 10, speed = 20, duration = 1 })

Use it fortop down views, boss arenas, or orbiting shots that show off a build.

targetoptionalOne player, a list of players, or nil for every player, also those who join later.

optionsThe mode, what the camera looks at, the field of view and the blend.

target

mode
How the camera behaves, where follow is the player's own camera.
positionfixed only
Where the camera stands, which a fixed camera needs.
xyz
subjectorbit and track only
The point, instance or player the camera circles or follows, which both of those modes need.
look_at
The point, instance or player the camera faces, by default the subject or straight ahead when fixed, and in follow the camera turns to keep it in view.
offsettrack onlydefault 0, 6, 12
Where the camera sits compared to the subject, at most 1000 studs away.
xyz
distanceorbit onlydefault 12
How far the camera stays from the subject, from 0.5 to 1000 studs.
heightorbit onlydefault 4
How high above the subject the camera sits, from -1000 to 1000 studs.
speedorbit onlydefault 0
How many degrees per second the camera circles the subject, from -720 to 720.
fov
The field of view in degrees, from 1 to 170, and nil uses the player's own.
input
Whether the player can turn and zoom the camera, which is on by default for follow and orbit and off for fixed and track.
durationdefault 0
How many seconds the camera takes to blend from the current view, up to 60, where 0 cuts straight to it.
easing
How the motion speeds up and slows down: linear, or quad, sine, cubic, quart, expo, back, bounce or elastic followed by _in, _out or _in_out.
for example

camera.move_to

function#

Moves the camera from the current view to a fixed pose over duration and holds it there. The player's camera input is off until set_input or reset.

camera.move_to(target: Target?, options: { … }) -> CameraMove

example

local move = camera.move_to(player, { position = math3d.vector3.new(0, 20, 30), look_at = player, duration = 2 })

Use it forcutscenes, intro flyovers, or showing players the door that just opened.

How many seconds the move takes, from 0 to 60.

for example

camera.look_at

function#

Turns the camera to face a point, an instance or a player, in any mode, and replaces a running move. In follow it keeps the target in view, a lock-on.

camera.look_at(target: Target?, at: (vector | Instance | Player)?, options: { … }?) -> ()

example

camera.look_at(player, math3d.vector3.new(0, 0, 0), { duration = 0.5 })

Use it forpointing players' cameras at a boss or a goal, or locking on to a target.

camera.set_fov

function#

Sets the field of view in degrees, and replaces a running move. Nil gives the player's own back.

camera.set_fov(target: Target?, fov: number?, options: { … }?) -> ()

example

camera.set_fov(player, 40, { duration = 0.3 })

Use it forzooming in for a sniper scope, or widening the view while a player sprints.
