Custom Camera Jitters at the Peak of Jump [SOLVED by me]

Tatanic_GamingYTalt · May 10, 2024, 6:40pm

I made a topic like this around a week ago but I’m making another because 1) a new problem occurred from rewriting the script and, most importantly, 2) the topic was forgotten, like every other one of my topics on this type of situation, this time without even a single reply.

Okay, so at the peak of Sonic’s jump, the camera moves up a little bit for… whatever reason. Here’s a video:
robloxapp-20240510-2038334.wmv (1.7 MB)
and here’s the scripts, first of the Camera:

local state = "idle"

game:GetService("RunService").Heartbeat:Connect(function()
	if script.Parent.Parent.Sonic.Position.Y <= script.Parent.VerticalBottom.CFrame.Y then
		state = "down"
	elseif script.Parent.Parent.Sonic.Position.Y >= script.Parent.VerticalTop.CFrame.Y then
		state = "up"
	elseif math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalCenter.CFrame.Y) <= .8 then
		state = "idle"
	end
	
	if state == "down" then
		if script.Parent.Position.Y - math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalBottom.Position.Y) < script.Parent.Position.Y then
			if math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalBottom.Position.Y) <= 1.6 then
				script.Parent.CFrame -= Vector3.new(0,math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalBottom.Position.Y),0)
			else
				script.Parent.CFrame -= Vector3.new(0,1.6,0)
			end
		else
			state = "idle"
		end
	elseif state == "up" then
		if script.Parent.Position.Y + math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalTop.Position.Y) > script.Parent.Position.Y then
			if math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalTop.Position.Y) <= 1.6 then
				script.Parent.CFrame += Vector3.new(0,math.abs(script.Parent.Parent.Sonic.Position.Y - script.Parent.VerticalTop.Position.Y),0)
			else
				script.Parent.CFrame += Vector3.new(0,1.6,0)
			end
		else
			state = "idle"
		end
	end
end)

and second of Sonic:

local state = script.Parent.Variables.state
local speedY = script.Parent.Variables.speedY.Value
local speedX = script.Parent.Variables.speedX
local jumpForce = script.Parent.Variables.jumpForce.Value
local groundAngle = script.Parent.Variables.groundAngle
local direction = script.Parent.Variables.direction
local collisionBtmRight = script.Parent.Variables.collisionBtmRight
local collisionBtmLeft = script.Parent.Variables.collisionBtmLeft

local sonicSizes = {
	standing = Vector3.new(0.081, 3.31, 2.571),
	standingHitbox = Vector3.new(0.162, 2.731, 1.366),
	
	jumping = Vector3.new(0.08, 2.571, 2.571),
	jumpingHitbox = Vector3.new(0.162, 1.841, 1.366),
}
local sonicPics = {
	idleRight =  "rbxassetid://15036394678",
	idleLeft =   "rbxassetid://17228640834",
	
	walkRight1 = "rbxassetid://15036394489",
	walkRight2 = "rbxassetid://15036394334",
	walkRight3 = "rbxassetid://15036394169",

	walkRight5 = "rbxassetid://15036393740",
	walkRight6 = "rbxassetid://15036393489",
	
	jump1 = 	 "rbxassetid://17258635607",
}

great, let’s add this topic to the list of forgotten ones

FurukanDev · May 10, 2024, 8:34pm

can you send a video, the video doesnt work

Tatanic_GamingYTalt · May 10, 2024, 10:58pm

The wmv? Okay, I’ll send another one recorded with OBS

Tatanic_GamingYTalt · May 10, 2024, 11:28pm

And I’ve just realized that I might need to rewrite this code for the third time, because horizontal movement (but I can just make a state 2), however the camera (in Sonic 1) may lock (for bossfights), it has camera bounds where the camera cannot move past and the screen may shake. Nice. But I’ll probably figure it out

Tatanic_GamingYTalt · May 12, 2024, 10:48am

Rewrote the script myself once more, and finally it works.

oh, i love the devforum
