I said to myself that it would be good to create a portal 2 mod because many people are looking for it on Minecraft and the only mod that exists is ,that with the portal gun could make you a portal 2 with the blocks to create test rooms because I had to start a project on portal gun in 1.12.2 know to completely recreate the game but portal gun and the only mod in 1.12.2 add only portal guns pls make a mod with the building blocks. pls.
