They weren’t, they were asking a question. Unless you’re talking about @twofoursixeight , they were trying to explain why @DriftUknown_YT couldn’t post
Currently, there is no way to make something follow you, unless you want to use a coordinate system. If you do, then that’ll take up a lot of space and memory.
Make sure to mark a solution if your question’s answered!
You could have your pet only appear in certain areas, saving time and memory. If you want anything besides the basic sentries, I recommend using this guide. For the generation of green keys, they would most likely have to be directly inserted into your inventory with a repeater → item granter setup. The repeater can be switched out for a trigger → trigger setup that uses recursion. Better pets could just use a faster repeater. Hope this helps!
Yes, I agree with ClicClac it would be way too inefficient to produce an actual system for that meaning it would be better just to send it straight to the inventory.
