aframe-super-shooter

Simple Shooter Kit for A-Frame.

This is a set of components and systems (under a single file) to provide a way of building simple shooting experiences, where a "shooter" shoots "bullets" that can hit "targets".

diagram

One entity bullet defines the look of all the instances of itself that are going to be shot.
Shooter defines the source position and orientation of the bullets.
Collisions among bullet's and target's bounding boxes are checked.

So you just define which entities are bullets, targets and shooters, and manage the logic among them using events:

Shooter:

Emit an event shot on a shooter to make it shoot
Emit an event changebullet on a shooter to change active bullet

Target:

Listen to event hit on a target to know when it was hit by a bullet
Listen to event die on a target to know when its life was finished
