Small snippet for cheating item pickup despite unit inventory being full.
This is done by periodic timer with distance checking that accounts for unit's collision size.
Generates custom event for triggering item pickup.
Allows for specifying arbitrary conditions via SmoothPickupPredicate interface for deciding whether to account for given unit in smooth item pickup process.
Example of usage: ItemRecipe, StackNSplit.
