Help and Feedback Scripting Support
#1

hello could anybody could explain how to detect if the camera touch ha certain part?
im new at scripting so i cant script much =(

Thx in Advance

#2

Could you elaborate? I don’t quite understand what you’re implying by “touch a part”.

#3

example:
ive created a part and called it water then if my camera hit the water it will create a fog and when i stop touching the water it will go back to normal

The camera isn’t a physical object so you can’t detect when the camera touches something. You can, however, check where the camera’s origin is by accessing its CFrame property.

There are a few threads and resources around about checking if the camera is in water, so be sure to search those threads up. You should always search before posting.

I suggest you using Region3. It’s a great way I guess.

Sorry for the late reply but you can do this !

local RunService = game:GetService("RunService")
local material

RunService.Heartbeat:Connect(function()
	local cameraPos = workspace.CurrentCamera.CFrame.Position + Vector3.new(0,2-workspace.Terrain.WaterWaveSize,0)
	local x, y, z = cameraPos.X, cameraPos.Y, cameraPos.Z

	local min, max = Vector3.new(x + 0.01, y + 0.01, z + 0.01), Vector3.new(x - 0.01, y - 0.01, z - 0.01)
	local region = Region3.new(max, min)
	region = region:ExpandToGrid(4)

	if region then
		local material = workspace.Terrain:ReadVoxels(region, 4)
		if material[1][1][1] == Enum.Material.Water then
			game.Lighting.Blur.Size = 10
			game.Lighting.ColorCorrection.TintColor = Color3.new(0.545098, 0.803922, 1)
		else
			game.Lighting.Blur.Size = 0
			game.Lighting.ColorCorrection.TintColor = Color3.new(1, 1, 1)
		end
	end
end)

I hope that was helpful ! :grinning:

local runService = game:GetService("RunService")

local radius = 1

local overlapParams = OverlapParams.new()
overlapParams.FilterType = Enum.RaycastFilterType.Whitelist
overlapParams.FilterDescendantsInstances = {workspace.WaterPart}

runService.Heartbeat:Connect(function(deltaTime)
    local cameraPosition = game.Workspace.CurrentCamera.CFrame.Position
    local parts = game.Workspace:GetPartBoundsInRadius(cameraPosition, radius, overlapParams)
    if #parts == 0 then return end
    print("Touching WaterPart")
end)

Try to create a part that is in the camera cframe every frame

local RunService = game:GetService("RunService")

local Cam = workspace.CurrentCamera

local part = instance.new("Part")
part.Size = vector3.new(3,3,3)

function StablishPartPos()
    part.CFrame = Cam.CFrame
end

RunService.RenderStepped:Connect(StablishPartPos)

Make a part at the camera’s position using runservice, then check if that part is hit.

I would do something like making a hitbox part that always follows the camera and use that to detect touching
