spawnConditions

Configures the conditions under which this entity variant can spawn.

When spawning, the selection of a variant happens in 3 steps:

1. Each condition is evaluated. The matching condition with the highest priority determines the priority of the variant. If no condition matches the variant is discarded.

2. Of all remaining variants, all except those with the highest priority are discarded.

3. Of the remaining variants, a random variant is chosen.
