In-World Purchase (IWPSeller) Gizmo question

Can you describe more specifically what you are trying to do? In my case I had trouble getting "Item Packs" to work but I was able to get sale of individual items to work. Is this what you might be having trouble with? 

The problem in the case of "Item Packs" is that the SKU did not end up matching the packs so the sale would fail. There is probably a way around this by first using script to identify the actual SKU of that IWP item pack. 

However, my approach was just to fall back on the sale of an individual auto-consumed In World Purchase item that upon purchase would add 10 of the consumable (effectively the same as an item pack). This worked using the youtube video for reference. 

edit: added working script sample

import * as hz from "horizon/core";

export class AutoConsumeHandler extends hz.Component<typeof AutoConsumeHandler> {
  static propsDefinition = {
  pvarName: { type: hz.PropTypes.String, default: "YOUR_VARIABLE_GROUP_NAME:YOUR_PVAR NAME" },// Replace with actual variable group and persitance variable name
};
  
preStart() {
    this.connectCodeBlockEvent(this.entity, hz.CodeBlockEvents.OnItemPurchaseComplete, (player, item, success) => { this.purchase(player, item, success); });
  }
  
start() {}

  //this works for auto-consumed items but the naming for the sku does not end up matching for IWP packs so we fall back on making our own packs
  purchase(player: hz.Player, item: string, success: boolean) {

    switch (item) {
      case 'YOUR_IWP_ITEM_SKU': // Replace with actual item SKU
        if (success) {
          console.log('Purchase succeeded for item: ' + item);

          const current = this.world.persistentStorage.getPlayerVariable(player, this.props.pvarName) ?? 0;//accounts for undefined - when a user hasn't scored yet
          const playerBalance = current + 10;
          this.world.persistentStorage.setPlayerVariable(player, this.props.pvarName, playerBalance);
        }
        else {
          console.log('Purchase failed for item: ' + item);
        }
        break;
      case 'ANOTHER_IWP_ITEM_SKU': // Replace with actual item SKU - The below is just adding 10 to the PVAR same as above so you'll want to do something different if you implement a second case. 
        if (success) {
          console.log('Purchase succeeded for item: ' + item);
          
          const current = this.world.persistentStorage.getPlayerVariable(player, this.props.pvarName) ?? 0;//accounts for undefined - when a user hasn't scored yet
          const playerBalance = current + 10;
          this.world.persistentStorage.setPlayerVariable(player, this.props.pvarName, playerBalance);
        }
        else {
          console.log('Purchase failed for item: ' + item);
        }
        break;
      default:
        console.log('Case for item not found: ' + item);
        break;
    }
  }
}

hz.Component.register(AutoConsumeHandler);
