* `damages_players`: if true, the projectile will deal damage to players.
* `damage_groups`: damage group information to use for `punch()`. May be a function of type `function(projectile, entity_def, projectile_def, obj)`
that returns dynamic damange group information.
* `allow_punching`: will the projectile punch entities it collides with. May be a function of type `function(projectile, entity_def, projectile_def, obj)`.
* `allow_punching`: will the projectile punch entities it collides with. May be either a boolean or a function of type `function(projectile, entity_def, projectile_def, obj)`.
* `survive_collision`: will the projectile surive collisions. May be either a boolean or a fnction of type `function(projectile, entity_def, projectile_def, type, ...)`.
* If `type` is "node" then the additional parameters `node, node_def` will be provided.
* If `type` is "entity" then the additional parameter `objet` will be provided.
* `behaviors`: a list of behavior callbacks that define the projectile's behavior. This mod provides the following
behaviors: `vl_projectiles.collides_with_solids`, `vl_projectiles.collides_with_entities` and `vl_projectiles.raycast_collides_with_entities`
* `sounds`: sounds for this projectile. All fields take a table with three parameters corresponding to the
