echo.util.verlet.Verlet

A Verlet physics simulation, using Dots, Constraints, and Composites. Useful for goofy Softbody visuals and effects!

This simulation is standalone, meaning it doesn't directly integrate with the standard echo simulation.

Static methods

`staticcloth(x:Float, y:Float, width:Float, height:Float, segments:Int, pin_mod:Int, stiffness:Float):Composite`

`staticrect(x:Float, y:Float, width:Float, height:Float, stiffness:Float, ?distance:Float):Composite`

`staticrope(points:Array<Vector2>, stiffness:Float, ?pinned:Array<Int>):Composite`

Constructor

`new(options:VerletOptions)`

Variables

`@:value(false)bounds_bottom:Bool = false`

`@:value(false)bounds_left:Bool = false`

`@:value(false)bounds_right:Bool = false`

`@:value(false)bounds_top:Bool = false`

`@:value([])read onlycomposites:Array<Composite> = []`

`drag:Float`

`fixed_framerate:Float`

The fixed Step rate of the Verlet World. The Verlet simulation must be stepped forward at a consistent rate, or it's stability will quickly deteriorate.

`read onlygravity:Vector2`

The amount of acceleration applied to each Dot every Step.

`height:Float`

Height of the Verlet World, extending down from the World's Y position.

`iterations:Int`

The amount of iterations that occur on Constraints each time the Verlet World is stepped. The higher the number, the more stable the Physics Simulation will be, at the cost of performance.

`width:Float`

Width of the Verlet World, extending right from the World's X position.

`x:Float`

The Verlet World's position on the X axis.

`y:Float`

The Verlet World's position on the Y axis.
