If a candidate portal is located, then, as determined by the distance in the current coordinate system, the portal teleports the individual to the nearest one. It then transforms these coordinates to destination coordinates: X- and Z-coordinate entries are multiplied if you are in the Nether or divided by 8 if you are in the Overworld, while the Y-coordinate is not modified. The game takes the coordinates when you use the portal. Understanding this conversion can be extremely useful. However, the Y-axis remains unaffected by this conversion. That is, players will move the equivalent of 8 blocks on the Overworld by moving 1 block horizontally on the Nether. The Nether's horizontal coordinates and distances in a 1:8 ratio are relative to the Overworld. Both linked portals will remain operational, but only the portal nearest to it will be controlled by the Nether Portal. Within a certain vicinity, creating several portals in the Overworld would all result in the same portal in the Nether, and vice versa. It is possible to use this connecting portal to return to its corresponding Overworld portal. Storage minecarts and powered minecarts can also pass through. Almost anything, including mobs (except the wither and ender dragon), thrown objects, and transport without passengers including boats, minecarts, and horses, can teleport through the portal. A new portal can be created if a portal is deactivated and the corresponding portal is used in the other dimension before it is reactivated. Otherwise, at or near the corresponding coordinates, a new portal is created. In case an active portal is already present in the other dimension, the player appears in that portal. This privilege, however, isn’t available in creative mode as the player is transferred immediately as they step into the portal. If you change your decision and don’t want to teleport, step out of the portal before it completes the animation, to abort this process. This is the case regardless of the dimension you are currently in. You need to stand in the Nether Portal block for at least 4 seconds to be transported to another dimension. You will be transported to the nether similar to the picture below: To use the Nether Portal, just walk through the purple area of the Nether Portal. Now that you have finished constructing it, all that’s left is to step into it. This means that the Nether Portal is active and you can travel into the Nether.

Once you have used the flint and steel on the portal frame, the center coordinates of the portal should glow and turn purple. Position your pointer on a bottom block of obsidian and then use the flint and steel. To do this, select the flint and steel in your Hotbar. Next, you need to activate the Nether Portal. More blocks can be used to make the portal larger, but 14 is the minimum number. The base of the Nether Portal should be 4 blocks wide, and the sides of the Nether Portal should be 5 blocks high resulting in a total of 14 obsidian blocks being used. Once you obtain flint and have iron ingots prepared from smelting iron ores, use the following recipe to make flint and steel. This item doesn’t exist naturally and has to be crafted by mixing iron ingots with flint, which is obtained from mining gravel. The second item required is a flint and steel. It is worth noting that obsidian will only be created if the water is poured onto the lava source.

Alternatively, you can make obsidian blocks by mixing lava and water.

Obsidians can be found in mines along with pools of lava. If you have a diamond pickaxe, you can mine for blocks of obsidian. Obsidian block collection can be performed in many ways. To make a Nether Portal in Minecraft you need 14 Obsidian blocks and 1 Flint and Steel.
