Topic category: Minecraft mod ideas exchange
I've been making a mod that uses a different system of progression that starts you in a custom dimension with custom blocks, plants, animals, metals, etc. However, because you start in a custom dimension, using the prebuilt portals given by MCreator just sends you back to the overworld. Currently, I've just been using an item that when right-clicked, it runs a procedure and teleports you to the right dimension, and then it sets your Y coordinate to a block that can see the sky. I don't feel safe using this though because I don't want a player to teleport to a dimension and fall into lava or some other hazard. Is there a good way to make dimensional travel that sends you to a custom dimension and then back to the custom dimension you start in?
Use that procedure, but make a check to see if y-1 is not lava/cactus/other hazard (check if it is that block, then use = false). Then, set it on a block that has CAN WALK THROUGH in advanced properties activated. Using the trigger for an entity colliding with the block, you've made a portal! Sadly, this does mean that technical aspects like cross-dimension chunk loading will be lost. You may also use another block that does nothing until you right-click with your custom igniter, replacing itself with the other, functional portal block, then maybe add sound effects, particles, make this damage the igniter, etc.
Thank you!
