So I have an issue that 300 people have had in this platform and I’m getting tired of it.
What I want to do is pull a rotation of a camera like this bag right here
Yes, I know, odd game, well it was my childhood and I don’t forget how the things rotate.
Basically, I want to rotate a camera blocky-like not smooth-like. 0.3 seconds and the camera rotates 45 degrees, 0.3 seconds and the camera rotates 45 degrees. Nothing polished, but rudimentary.
The issue is that I don’t know how, and I’ve been looking EVERYWHERE for info and found nothing, bad code, good code, someone even used metatables, eww. Nothing of what I want FUUUUUU
When rotating a camera around a object usually it is fixed to be looking and rotating a ta central point.
For this all you would need to do is move the camera around a single point at fixed distance.
We can use the bag as a central point for its rotation as this means we can use the look vector of a invisible part to achieve a smooth rotation at set distance. This requires a few steps on repeat:
Work out the amount per move and wait time
Rotate the part
Put camera at a distance from the parts look vector
I think you should rotate the object instead of the camera. This is what i do when i use viewportframes and i think its easier than rotating the camera.
Rotating a part uses more resources than if you were to just rotate the camera.
Altough considering that what I need to rotate is just a mesh part, nothing of that block buildings, I could rotate the part and keep on with my life, but I want to rotate the camera instead of the part so it doesn’t get heavy låter on.
Maybe I should just do that, just rotate the part, but I’m thinking it can get ugly fast.
No, I haven’t, do you have any sources I can check?
When I use viewport frames like that I usually go for a simple up and down breathing and make it spin. I use animations as I see it as the easiest and doesn’t take up too much resources. You could rotate the camera, I just didn’t because I was too lazy.
Try running this as a localscript, you can probably figure something out! (Don’t mind my bad code its just an example; you should be storing constants)
local tau = 2*math.pi
local t = 0
local cam = workspace.CurrentCamera
local radius = 5
local p = Instance.new("Part", workspace)
p.Anchored = true
p.Position = Vector3.new()
while true do
t += tau / 100 --// 1/100 of a circle, i.e. 3.6 degrees.
cam.CFrame = CFrame.lookAt(Vector3.new(math.sin(t)*radius, 0, math.cos(t)*radius), Vector3.new())
wait()
end
By storing constants, I mean I probably should not call the constructor multiple times constructing the same value. (Generally calculations etc.)
So instead of:
..., Vector3.new())
It should be:
local ZERO_VECTOR = Vector3.new()
...
..., ZERO_VECTOR)
To skew the angle a little, you can add another vector to the first argument (such as (0,-5,0) for looking from below).
To make it look a bit further away, you can adjust the radius variable.
local tau = 22.5*math.pi
local t = 0
local cam = script.Parent.CurrentCamera
local radius = 100
while viewport.Visible == true do
t += tau / 100 --// 1/100 of a circle, i.e. 3.6 degrees.
cam.CFrame = CFrame.lookAt(Vector3.new(math.sin(t)*radius, 0, math.cos(t)*radius), Vector3.new())
wait(0.15)
end
Thanks for your help, I genuinely don’t know what sine cosine and tangent is, I approved that part in school but never understood it.
I will be seeing if there’s something else. I couldn’t change the position of the camera to be higher, but I guess it doesn’t matter, I just want to end this part for once.
