Teleporter Mod for java edition

I'm trying to make a teleporter mod for Minecraft Java Edition. The Oak Teleporter is a redstone-activated block that stores its own destination coordinates internally within its BlockEntity, making each placed teleporter completely independent with no shared network or global linking system. Players can set the destination through the GUI, which saves the target position in the same dimension as the block, and teleportation will only occur if the block is actively powered by redstone, a destination has been set, and the player remains in the same dimension. The destination data persists through world saves and reloads but is lost if the block is broken, ensuring a localized, single-destination teleport system that is stable, predictable, and dimension-restricted. Future BASIC blocks to craft it. 1Compass, 1Redstone Block, 1Ender eye, 4Gold brick, And any 2 same builder blocks to make it on crafting table. builder blocks are oak, copper, iron, and diamond. any help would be helpful
