An anchor portal is like a magic door that lets you go from one place to another really quickly.
Think of it like this: you are in your living room and you want to go to your friend's house. But instead of walking or taking a car, you can just use the anchor portal to instantly appear at your friend's house.
An anchor portal needs an anchor, which is like a special key that is used to open the portal. To make an anchor, you need to have a certain item or block in the game. Once you have the anchor, you can create a portal by putting it on the ground and then throwing a special item into it.
When you throw the item into the anchor portal, it creates a magical connection between two different spots. This means that you can travel back and forth between two places as many times as you want just by stepping or hopping through the portal.
Overall, an anchor portal is a really cool way to travel faster and make transportation easier in your game.
