Methods

ReportFixture(b2Fixture, b2Vec2, b2Vec2, float)

System.Single ReportFixture(b2Fixture, b2Vec2, b2Vec2, float)(Box2D.Dynamics.b2Fixture fixture, Box2D.Common.b2Vec2 point, Box2D.Common.b2Vec2 normal, System.Single fraction)

Called for each fixture found in the query. You control how the ray cast proceeds by returning a float: return -1: ignore this fixture and continue return 0: terminate the ray cast return fraction: clip the ray to this point return 1: don't clip the ray and continue

Parameters:

fixture (Box2D.Dynamics.b2Fixture) - the fixture hit by the ray

point (Box2D.Common.b2Vec2) - the point of initial intersection

normal (Box2D.Common.b2Vec2) - the normal vector at the point of intersection

fraction (System.Single)

Returns:

System.Single - -1 to filter, 0 to terminate, fraction to clip the ray for closest hit, 1 to continue
