When you get the event to occur I believe you are passed (result). result contains the pointer to the other. i.e. result.other = other entity. You can then operate on enabled. Now if you are not actually colliding with the other object you could at the top of the code do this.
Collider2.attributes.add(“otherObj”, { type: ‘entity’, title: ‘OtherObject’ });
Toss the other object into the attribute created. Then you could use this.otherObj.enabled = to true/false.
OR
You could use…
this.app.root.findByName(“OtherObjName”).enabled = true;
I have not tried this yet but I would disable this.entity after you enable otherObj. Hope this helps and answers your question.
