There are 2 portals you can craft in Minecraft. The Nether Portal and The End Portal.
You can already make portals in Minecraft for Xbox and PC. In the new app they should already have them too.
all portals are 5 blocks by 4 blocks. If you saw a very big portal, then the person who made it hacked by inventory editing and got the portals blocks and just putting them on top of each other
u don't
You can make a portal to the nether on minecraft with 10 obsidian arranged like this in a space somewhere: O=Obsidian E= Empty EOOE OEEO OEEO OEEO EOOE You can also get mods where there are more portals
Get the mod and usually its glowstone or another block the creator of the mod has added in.
The moon is unreachable in vanilla minecraft, but various mods allow you to make portals there, the current height limit is about 255 blocks high.
You can't make them. You need to find a stronghold and fix the end portal by filling in the missing blocks with eyes of wonder to fix it
you step into the purple portal and wait a second. then it will load you to the nether.
The only portal you can make right now is a Nether portal. Same with the PC version. (without mods)
The nether portal and the newest one, the end portal.
No. But there is something else to go to the nether. But you can only go to the nether in survival.
