Collision ends if actor isn't actively moving into collider...

[brettkoz]

I'm building a beekeeping game where you have to walk around your bee yard and interact with your hives. As you walk around the yard, you should have the ability to see a popup of hive information when you collide with a hive. The problem is, I have to have collisions set to passive for the info window to stay up, otherwise, with collisions active I have to be actively walking into the hive to keep the information window up... My question is, is there a way to allow a buffer zone for collisions, where the onCollisionEnd doesn't get called immediately upon releasing the direction key?

@brettkoz Thanks for the question! Sorry I missed this before your discord post.

@mattjennings Suggested using a child actor as a sensor

hm, i would add an invisible, passive actor as a child to the hive that acts as the "buffer zone", then listen for collision events from the player on that.
https://excaliburjs.com/docs/collision-events/#collision-start-collisionstart docs for the collision events

// typing this off the top of my head in discord so some things might be wrong


class Beehive extends ex.Actor {
   buffer: ex.Actor

   constructor(args) {
      super(args)

      this.buffer = new ex.Actor({ 
         radius: 10, 
         collisionType: ex.CollisionType.Passive,
         // .. whatever else as necessary
      })


      this.addChild(this.buffer)

      this.buffer.on('collisionstart', ev => {
         // if collision is with player, show label
      })

      this.buffer.on('collisionend', ev => {
         // if player stopped colliding, hide label
      })
      
   }
}
