Support area effect damage

[sfiera]

Antares does not natively support any kind of “area effect damage”. Generally, damage is applied only as a result of a collision between two objects. There are workarounds, but it would be nice to have a good way to make an weapon that damages everything within a radius.

I’m not sure exactly how I’d implement it.

As a plugin developer, I think that it would be natural as part of a big explosion’s create action (like, {type: "blast", radius: 100, damage: 1000}), dealing damage to all nearby objects that collide.as.object. However, that doesn’t fit well into the current definition of “action”, which normally is an interaction between a subject and direct object.

Might also be sensible to add a radius parameter to heal, and maybe split it into heal/harm.
Should there be some ability for the damage to fall off with decreasing radius?
