Iterating two lists from a system

[Freaksed]

How would I check two entity sets against each other? As a specific example having items that can be picked up by a player. So I have a system that iterates all the pickable items and checks their distance against the players, if the player is in range the item gets picked up and added to their inventory.

ecs-lib/src/index.ts

Line 423 in e4738e0

protected query(componentTypes: number[]): Iterator<Entity> {
