Define a blaster-bolt component and mixin

[pookage]

• [ ] Define a blaster-bolt component
• [ ] The component should have raycaster as a dependency with objects: .blastable
• [ ] The component should have a range property which defaults to 5
• [ ] The component should have a lifespan property which defaults to 1000
• [ ] The mixin should contain a raycaster component that points 1m ahead
• [ ] The mixin should contain a geometry component with a cylinder primitive
• [ ] The bolt should be ~30cm with a 5cm diameter
• [ ] The bolt should be red
• [ ] When spawned via play(), the blaster-bolt component should draw a line path from its spawn position to range meters directly ahead given the rotation of the entity
• [ ] The blaster-bolt should translate the attached entity along the path so that it reaches the end by lifespan ms.
• [ ] When the blaster-bolt reaches the end of the path it should return itself to scene.components["pool__blaster-bolt"] via returnEntity()
• [ ] If the raycaster intersects any blastable entities, it should emit a "blasted" event on that entity
• [ ] If the raycaster intersects any blastable entities, it should return itself to the pool as if it had completed its path

If we want to do a simple trajectory then a THREE.LineCurve3 should be fine to draw the trajectory, which we can then call .getPoint(alpha) on to get the correct point in 3D space.

That said, it probably makes more sense to use a THREE.CatmullRomCurve3 instead, which would allow us to create trajectories later if we wanted to create different ammo types / guns etc.

To get the alpha value for .getPoint:

1. When the animation begins, we set age to 0
2. In the tick(time, deltaTime) function, we add deltaTime to the age
3. We can derive alpha as age / lifespan
