Physics 2DScripts: EdgeCollider2DComponentFeature: 2D Physics (≈45 KB)

Optional feature

EdgeCollider2D is part of 2D Physics. A build includes it only when a scene, prefab or script uses it — see Feature cropping.

From a script

import { EdgeCollider2DComponent } from "mmpx";

const edgeCollider2D = this.entity.TryGetComponent(EdgeCollider2DComponent);

Full API: EdgeCollider2DComponent.

Fields

Field	Type	Default	Description
Is Trigger isTrigger	boolean	false	Reports overlaps (OnTriggerEnter2D …) instead of colliding
Layer layer	physics layer	0	Physics layer — Project Settings → Physics decides which layers collide
Offset X offsetX	number	0
Offset Y offsetY	number	0
Points points	json	[[-100,0],[100,0]]	The strip as [[x, y], …] in local pixels
Loop loop	boolean	false	Joins the last point back to the first

Material

Field	Type	Default	Description
Density density	number (0 … ∞)	1	Mass per square metre — used when the Rigidbody2D has Use Auto Mass on
Friction friction	number (0 … ∞)	0.4	0 = ice; the two colliders' frictions combine (√(a·b))
Bounciness bounciness	number (0 … 1)	0	Restitution: 0 = no bounce, 1 = keeps all its speed (the higher of the two wins)
