I'm making a custom dimension and I it's not crashing, but the portal wont activate. It's made of sandstone and is supposed to activate by fire. Here are my codes for it:

Lighting a portal with vannila blocks can be hard as u can't edit the BlockFire class. But anyway, what u need to do is in the block class ur trying to light it with u need to add a method onBlockAdded (I think that's what it's called) and copy the code in it from BlockFire. Then change Blocks.portal into (BlockPortal)MainModClass.yourPortalBlock. I will provide some code in a bit cause I'm not on my computer.

Then change Blocks.portal into (BlockPortal)MainModClass.yourPortalBlock. I will provide some code in a bit cause I'm not on my computer.

I was actually following an example on GitHub "Goblins and Giants", I ended up watching a video because I couldn't figure out how the portal activated and realized it was an item, so I looked at the name in the video and saw how it was done, so I created an item for it and it worked, this is the item's code:

package com.multiverse.items;

import net.minecraft.client.renderer.texture.IIconRegister;

    }

@Override

    {
	if(!par2World.isRemote)
	{

	}

	return par1ItemStack;
    }
}

My only problem is the portal isn't spawning where the frame is built, but a block away from it, sometimes perpendicular to the portal. I'm guessing I have to look at the code that spawns the blocks. Thanks for helping me.

EDIT: Okay, so apparently the item spawns the portal, you don't need to build a frame.

EDIT: I don't like the way this item method, it's less controllable, so could you still post a code for a block that activates the portal. I tried making a block based off of flame block, adding the method you said, and making the changes, but it didn't activate the portal, so maybe I'm missing something.

Also my protal frame texture isn't loading, I have this in my portal block:

	@Override
public void registerBlockIcons(IIconRegister par1IconRegister)
{
	this.blockIcon = par1IconRegister.registerIcon(Strings.MODID + ":MistWoodsPortal");
}

and in my textures/blocks folder I have the texture image for it and a metadata file with the same name that has:

{
  "animation": {}
}

Manslaughter777 · November 4, 2014

Ah that's easy to fix!

In the items code you will see there is a lot of lines of code than determine the x, y, and z pos. read them carefully and change the y pos of all the blocks to where u want it

Wait... why not just using a PlayerInteractEvent, which is easier? You have everything you need in that event.

I tried that, but I wanted it to be in front of the player so I used this:

,but it'd always place the portal position for "if (par3EntityPlayer.cameraYaw > -45 && par3EntityPlayer.cameraYaw < 45)", even when my camera view was in other directions.

Wait... why not just using a PlayerInteractEvent, which is easier? You have everything you need in that event.

Making a new fire block is pointless, in my opinion..

How do you do this? I looked everyone on these forums, Github, and Google, and I don't see any examples of this. I have it set up with "MinecraftForge.EVENT_BUS.register(new MistPortalActivationHandler());" in my MainRegistry and in a new class I have:

"@SubscribeEvent
public void onPlayerInteractEvent(PlayerInteractEvent event){

}"

event.x, event.y, and event.z are the coordinates of the block you interacted with. You obviously check if the block at those coords is a sandstone block. Note that the event fires even if you left click, so add a check for event.action aswell!

Then you need to check the item that the player is holding, and we have an event.entityPlayer. Finally, the side of the block the player has interacted with: event.face. 1 is the top face, so you should go with that.

At this point we checked if the player right clicked with a flint and steel in hand, on the top side of a sandstone block. Now you should set your portal blocks with event.world.setBlock. But be careful, because you also need to check for the shape of the portal around (and by that I also mean its orientation)

I won't provide any code for now, you have to try by yourself!

That worked, thanks. I still have a problem with the portal texture showing as missing texture though, I'll repost what I have:

	@Override
public void registerBlockIcons(IIconRegister par1IconRegister)
{
	this.blockIcon = par1IconRegister.registerIcon(Strings.MODID + ":MistWoodsPortal");
}

I have the image texture and a mcmeta file with { "animation":{} }.

Also I have a problem with my portal block, I want to make it so the portal is destroyed when the frame is gone, if I remove this from my portal block:

	@Override
    public void onNeighborBlockChange(World p_149695_1_, int p_149695_2_, int p_149695_3_, int p_149695_4_, Block p_149695_5_)
    {
    }

So the portal will be destroyed when the frame is broken, the portal doesn't spawn because onNeighborBlockChange detects portal blocks missing before all portal blocks can be placed. Could I use onBlockBroken, or is there a way around this?

I just tried this, but it isn't working, I hit the frame in many different spots on the sides and it wont break (I haven't added the code for breaking top and bottom frame blocks and the code for a portal going in another direction, but I have two frames facing different directions and I tested them both):

package com.multiverse.blocks;

import net.minecraft.init.Blocks;
import net.minecraftforge.event.world.BlockEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class MistWoodsPortalFrameBreakHandler {

@SubscribeEvent
public void onBlockBroken(BlockEvent.BreakEvent event){
	if (event.block == Blocks.sandstone){
		for (int i=-2;i<0;i++){
			for (int j=-3;j==-3;j=0){
				if (event.world.getBlock(event.x+1+j, event.y+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock &&
						event.world.getBlock(event.x+1+j, event.y+1+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock &&
						event.world.getBlock(event.x+1+j, event.y+2+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock &&
						event.world.getBlock(event.x+2+j, event.y+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock &&
						event.world.getBlock(event.x+2+j, event.y+1+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock &&
						event.world.getBlock(event.x+2+j, event.y+2+i, event.z) == MultiverseBlocks.MistWoodsPortalBlock){
					event.world.setBlock(event.x+1+j, event.y+i, event.z, Blocks.air);
					event.world.setBlock(event.x+1+j, event.y+1+i, event.z, Blocks.air);
					event.world.setBlock(event.x+1+j, event.y+2+i, event.z, Blocks.air);
					event.world.setBlock(event.x+2+j, event.y+i, event.z, Blocks.air);
					event.world.setBlock(event.x+2+j, event.y+1+i, event.z, Blocks.air);
					event.world.setBlock(event.x+2+j, event.y+2+i, event.z, Blocks.air);
				}
			}
		}
	}
}
}

I feel like the problem is a completely new topic, so I made a new topic with my current problem.
