軌跡 物件用於創建兩個附件之間的軌跡效果。隨著附件在空間移動,在定義的平面上繪製了紋理。這通常用於創建效果,以視覺化像箭頭軌跡、腳印、輪胎軌跡和類似效果的運動。

This example demos the functionality of Trails by creating a BasePart to be the parent of the trail. Two Attachments are then parented to the part. The positions of these two attachments (more importantly the distance between them) determines where the trail is drawn as the part moves.

For these attachments to create a trail as described, a new Trail is parented to the part and its Attachment0 and Attachment1 are parented to attachment0 and attachment1 respectively. Finally, TweenService is used to move the part back and forth, showing how the trail is drawn as the part (and its attachments) move.

Creating a Part with a Basic Trail

local TweenService = game:GetService("TweenService")
-- Create a parent part
local part = Instance.new("Part")
part.Material = Enum.Material.SmoothPlastic
part.Size = Vector3.new(4, 1, 2)
part.Position = Vector3.new(0, 5, 0)
part.Anchored = true
part.Parent = workspace
-- Create attachments on part
local attachment0 = Instance.new("Attachment")
attachment0.Name = "Attachment0"
attachment0.Position = Vector3.new(-2, 0, 0)
attachment0.Parent = part
local attachment1 = Instance.new("Attachment")
attachment1.Name = "Attachment1"
attachment1.Position = Vector3.new(2, 0, 0)
attachment1.Parent = part
-- Create a new trail
local trail = Instance.new("Trail")
trail.Attachment0 = attachment0
trail.Attachment1 = attachment1
trail.Parent = part
-- Tween part to display trail
local dir = 15
while true do
dir *= -1
local goal = { Position = part.Position + Vector3.new(0, 0, dir) }
local tweenInfo = TweenInfo.new(3)
local tween = TweenService:Create(part, tweenInfo, goal)
tween:Play()
task.wait(4)
end
