[1.7.10] [Solved] usePortal does not work in this version.

Atila1091 · June 26, 2015

I have not found someone to help me really. :'(

To solve this topic I decompiled the Aether mod 1.2.5 using the MCP, but only 90% of my poblema was completed.

http://www.minecraftforge.net/forum/index.php/topic,31521.0.html

The public void usePortal(int par1, Teleporter teleporter) it does not exist anymore.

I need something to replace it:

minecraft.usePortal(((BlockAetherPortal)AetherBlocks.Portal).getDimNumber(minecraft.thePlayer), teleporter);

The code adapted to 1.7.10:

public class TickHandler 
{
    private int tickCounter;

    @SubscribeEvent
    public void onTick(TickEvent.ServerTickEvent event)
    {
        if (event.side == Side.SERVER && event.phase == TickEvent.Phase.START)
        {
            this.onTickInGame(event.type);
        }
    }

    public void onTickInGame(TickEvent.Type type)
    {    	
        if (Minecraft.getMinecraft().thePlayer != null)
        {
            EntityClientPlayerMP entityplayersp = Minecraft.getMinecraft().thePlayer;

            if (((EntityPlayer)(entityplayersp)).dimension == mcreator_aether.DIMID && ((EntityPlayer)(entityplayersp)).posY < -2D)
            {
                Class class1 = null;
                NBTTagCompound nbttagcompound = new NBTTagCompound();

                if (((EntityPlayer)(entityplayersp)).ridingEntity != null)
                {
                    class1 = ((EntityPlayer)(entityplayersp)).ridingEntity.getClass();
                    ((EntityPlayer)(entityplayersp)).ridingEntity.writeToNBT(nbttagcompound);
                    ((EntityPlayer)(entityplayersp)).ridingEntity.setDead();
                }

                double d = ((EntityPlayer)(entityplayersp)).motionY;
                minecraft.usePortal(((BlockAetherPortal)AetherBlocks.Portal).getDimNumber(minecraft.thePlayer), teleporter);
                Minecraft.getMinecraft().thePlayer.setLocationAndAngles(((EntityPlayer)(entityplayersp)).posX, 256D, ((EntityPlayer)(entityplayersp)).posZ, ((EntityPlayer)(entityplayersp)).rotationYaw, 0.0F);

                if (class1 != null && !Minecraft.getMinecraft().theWorld.isRemote)
                {
                    Object obj = null;

                    try
                    {
                        Entity entity1 = (Entity)class1.getDeclaredConstructor(new Class[]
                                {
                                    net.minecraft.world.World.class
                                }).newInstance(new Object[]
                                        {
                                		Minecraft.getMinecraft().theWorld
                                        });
                        entity1.readFromNBT(nbttagcompound);
                        entity1.setLocationAndAngles(((EntityPlayer)(entityplayersp)).posX, 256D, ((EntityPlayer)(entityplayersp)).posZ, ((EntityPlayer)(entityplayersp)).rotationYaw, 0.0F);
                        Minecraft.getMinecraft().theWorld.spawnEntityInWorld(entity1);
                        entityplayersp.mountEntity(entity1);
                    }
                    catch (Exception exception)
                    {
                        System.out.println("Failed to transfer mount.");
                    }
                }
                
                if (Minecraft.getMinecraft().gameSettings.difficulty == EnumDifficulty.PEACEFUL)
                {
                    entityplayersp.fallDistance = -64F;
                }
                
            }
        }
    }
}

Who can help me, please write in java, but do not try to explain why I learned Java alone. :'(

This is very important for me because I'm developing a dimension at the sky with my ideas and how the sky is necessary that there is a teleport if a Player fall out of the island.

The code is almost perfect even though the minecraft 1.2.5.

Please help me. :'( :'( :'(

This check is pointless:

event.side == Side.SERVER

You are alredy on server.

ServerTickEvent runs for WHOLE server, twice per tick (phases).

1. You cant use Minecraft.class for server tick event. Minecraft.class in client-side.

2. If you want to check all players - use world#playerList or something (look into world class, there is list of all online players in given world).

Overally - you are missing the point of sided methods.

world/player in Minecraft is the object of CLIENT, not server.

E.g: this check;

!Minecraft.getMinecraft().theWorld.isRemote

Is literally stupid.

Please read more about logical sides and tick events.

Also: consider using WorldTickEvent - it runs like server tick, but per-world.

My code does not work when I set for EntityPlayerMP.

There is no teleport to one player.

What I missed?

You have no clue about what are you doing, do you?

Please learn basic java (or logic), because if you can't see the the fact that you are using nulls, then I really can't help you, even if I tried REALLY hard, sorry.

public Entity p_149670_5_;

Also: "decode" your code (names).

I managed to do my work event.

It works with many things, but does not work with teleport.
