A mining strike touches several systems at once. The interaction has to register, inventory has to receive the correct reward, and the resource has to remember that something happened to it. Replaying the same impact must not quietly award another item.
A development test took that sequence beyond the visible hit. It saved the inventory and resource state, unloaded the world, and loaded it again. The checks covered the returning player’s position and collision, the inventory and hotbar, and the rock’s depletion state. A repeated impact was also checked for an extra reward.
The visible event lasted a moment. Remembering it required the interaction, inventory, resource and save systems to agree. That was the milestone: coming back to a world that still knew what had happened to this rock. There is much more to build around it, but this small loop held together.
