In Bedrock Edition they spawn in certain squares adjacent to the portals in the Overworld, not inside them. Zombified piglins have a chance to spawn on the bottom frame of the portal in the Overworld in Java Edition if any nether portal block above receives a block tick. In Bedrock Edition, a parrot on the player's shoulder prevents the player from going through the portal. Therefore, an entity can only travel though nether portals again, once it is not touching any nether portal for 15 seconds. Unlike players, other entities travel through portals instantly, and once they reach the other side, there is a cool-down time for 300 game ticks (15 seconds), in which they cannot go through any nether portals. Most entities can travel through portals, including mobs (except the wither and ender dragon), thrown items, and transportation without passengers (neither mobs nor player), including boats, minecarts and horses. However, multiple portals can be exploited to farm obsidian. The usual cause for this is when the player's Nether-side portal is deactivated by a ghast, and then the player dies in the Nether, spawns, and then re-enters the Nether through the Overworld-side portal. If a portal is deactivated, and the matching portal in the other dimension is used before it is re-activated, a new portal may be created (unless there is another active portal within range).

Otherwise, a portal is created at or near the corresponding coordinates. If there is already an active portal within range (about 128 blocks) in the other dimension, the player appears in that portal. However, in Creative, the wait time is one game tick ( 1⁄ 20 second) for the player to transfer between dimensions.

The player can step out of a portal before it completes its animation to abort the teleport. When a player in the Overworld or the Nether stands in a nether portal block for 4 seconds, the player is taken to the other dimension.

There is an infinitesimal chance of failure for the corresponding portal to generate in the Nether, leaving the player trapped until death or until another portal can be constructed, either in the Nether or by another player in the Overworld. When a portal is used by a player, if no corresponding portal within range exists in the other dimension, one is created there see § Portal search and § Portal creation. The fire must be the last placed block in the structure-a fire on an incomplete frame does not result in the portal activating upon the placement of the last obsidian block. Nether portals can be activated only in the Overworld or the Nether they cannot be activated in the End and customized dimensions. The fire can be placed in any manner, including use of flint and steel or a fire charge, the impact of a fireball or small fireball, a lightning strike, or natural spread of fire to flammable material adjacent to the portal. This creates portal blocks inside the frame, resembling a vortex. Once a frame is constructed, it is activated by fire placed inside the frame. A nether portal cannot be built horizontally like an end portal. Adjacent portals can share obsidian blocks. by placing mined obsidian, by completing a ruined portal, or by casting it in place using lava and water. The obsidian can be placed in any manner, e.g. The four corners of the frame are not required, but portals created by the game always include them, resulting in 4 free/extra obsidian. 2.2 Portal linkage between Overworld and NetherĪ nether portal is built as a vertical, rectangular frame of obsidian (4×5 minimum, 23×23 maximum).
