This system relies on actor tags. To use it, add the corresponding upgrade name as a tag to any actor (e.g. "Expansion IV"). Once that upgrade has been acquired, all actors or meshes tagged with the matching name will automatically be destroyed when upgrades are loaded.
To add a new expansion license, go to ShopSimulator > Item > Computer > Management and open WB_Management_Expansions. Copy one of the expansions here and place it in the appropriate position. Now you can fill in the information.
Expansion Name: This is the name you’ll later use as a tag for your expansion in order to delete it.
Expansion Price: This is the cost to purchase the expansion. The purchase is saved as soon as the player confirms and saves it.
To add a new expansion to your supermarket level, go to ShopSimulator -> Main and drop the "BP_ShopExpansion" actor into your level. Position it wherever you like. To adjust it, click on it and navigate to the default section.
After this, you'll need to add the expansion name from the setup above as an actor tag to label the expansion with the correct license.
