176*****795 Laya2.6.0beta源码Physics.ts类中_sendEvent方法contact.getHitInfo = function (): any { var manifold: any = new this.[b]box2d[/b].b2WorldManifold(); ... }这里的this不是Physics类的当前对象，this.box2d undefined
186*****645 Aar0n var manifold = new this.box2d.b2WorldManifold();应该改成 var manifold = new Physics.I.box2d.b2WorldManifold(); 吧
