class Trail
extends Engine.Actor

//============================================================================= // Trail: An trail Actor. // David Fournier //=============================================================================

Variables
`vector`	`ActorOffset` Offset from the attached actor in its coordinates.
`bool`	`BeginPoint` The first section has a null width.
`bool`	`CrossMode` Use a cross instead the simple line for each section.
`float`	`CurRotation` Current section rotation.
`bool`	`DrawOutline` Draw the outline in addition to the ribbons.
`float`	`FadePeriod` Time lenght of a section fade.
`color`	`OutlineColor` Color used for the outline.
`color`	`RibbonColor` Color used for the ribbons.
`float`	`RotationSpeed` Rotation speed in turn per second.
`float`	`ScaleLin` Lenght added to the ribbon width each second (can be negative).
`float`	`SpawnFreq` Number of new sections per second.
`float`	`UVScale` Texture per Unreal unit.
`float`	`Width` Initial width.

Function Summary
`void`	`AddSection(vector Position)` // Add manually a new section to the trail.
`void`	`Init()` // Initialise the trail when all parameters are set.
`void`	`Reset()` // Reset the trail.
