This load level also spreads to adjacent chunks but they get lower for each chunk. This results in 8 more fully loaded "entity ticking" chunks with gradually fewer loaded chunks further out. These chunks remain loaded for 15 seconds but this timer gets refreshed each time the entity passes through the portal including mobs wandering through it from either direction.
This can be used to permanently load chunks, creating a "chunk loader". Permanently-loaded chunks created using chunk loaders create a considerable amount of lag.
A new portal is generated in the closest empty area if no portal is found in range. Horizontal coordinates and distances in the Nether are proportional to the Overworld in a ratio.
That is, by moving 1 block horizontally in the Nether, players have moved the equivalent of 8 blocks on the Overworld. This does not apply to the Y-axis. The Java floor method used in these conversions rounds down to the largest integer less than or equal to the argument toward smaller positive values and toward larger negative values , so a coordinate of When an entity starts colliding with a nether portal block , the game records the coordinates of the entity.
The game then converts those coordinates into destination coordinates as above: The entry X- and Z-coordinates are multiplied if the entity is in the Nether or divided by 8 if the entity is in the overworld, while the Y-coordinate is not changed.
Starting at these destination coordinates, the game looks for the closest portal point of interest POI. An active portal for this purpose is defined as a portal block that does not have another portal block below it; thus, only the lowest portal blocks in the obsidian frame are considered. A single portal block generated in and placed using server commands would be a valid location. If a candidate portal is found, then the portal teleports the entity to the closest one as determined by the distance in the new coordinate system including the Y coordinate, which can cause seemingly more distant portals to be selected.
Note that this is Euclidean distance , not taxicab distance. The distance computation between portals in the range is a straight-line distance calculation, and the shortest path is chosen, counting the Y difference.
For players, if no portals exist in the search region, the game creates one , by looking for the closest suitable location to place a portal, within 16 blocks horizontally but any distance vertically of the player's destination coordinates. When enough space is available, the orientation of the portal is random. The closest valid position in the 3D distance is always picked. A valid location exactly 3 wide in the shorter dimension may sometimes not be found, as the check for a point fails if the first tried orientation wants that dimension to be 4 wide.
This is likely a bug. If that fails, too, a portal is forced at the target coordinates, but with Y constrained to be between 70 and 10 less than the world height i. This provides air space underground or a small platform if high in the air. In Bedrock Edition , these obsidian blocks are flanked by 4 more blocks of netherrack on each side, resulting in 12 blocks of platform.
If a portal is forced into water or lava, the liquid immediately flows into the generated air blocks, leaving the player with no airspace. However, a glitch can prevent this water from flowing into the portal: if the liquid would flow both vertically and horizontally into the air pocket, it instead flows only vertically, so the blocks on the platform's outer corners never become water source blocks. Note: These videos do not mention that nether portals on the Nether ceiling link up with Overworld portals.

You can use either flint and steel or a fire charge to activate the portal. In this tutorial, we will use flint and steel. So, select the flint and steel in your hotbar.
Position your pointer the plus sign on a bottom block of obsidian and then use the flint and steel. The game control to use the flint and steel depends on the version of Minecraft:. Once you have use the flint and steel in the portal frame, the center of the portal should glow and turn purple. This means that the nether portal is active and you can transport to the nether. You will be transported to the nether. Once you are in the nether, there will be another portal to return you to your Minecraft world.
