Please HELP ME !!!!!

[Mazetar]

The error you are getting is " java.lang.ClassCastException: net.minecraft.client.particle.EntityDiggingFX cannot be cast to net.minecraft.entity.player.EntityPlayerMP"

 

And from the log you see that it gets it right after this:

at skycraft.blocks.PortalBlock.onEntityCollidedWithBlock(PortalBlock.java:46)

 

So while trying to preform the onEntityCollidedWithBlock()  method in the PortalBlock file on line 46.

It caused this error.

 

Let's check line 46 of that file and see what it says?

 

Pasting your code into www.pastebin.com and setting Syntax Highlighting to Java, makes it a lot easier for others to read your code files

Here I created one for your code:

http://pastebin.com/cCsGd37f

 

 

Looking at line 46 it seems you are doing this:

EntityPlayerMP thePlayer = (EntityPlayerMP) par5Entity;

 

Which is causing the crash, since the par5Entity is NOT an EntityPlayerMP but an different Entity. And you are telling it to use that entity as a EntityPlayerMP!

 

What you need to do is to do a check before you do the rest of the code to see IF the par5Entity IS a EntityPlayerMP at all. To do this I suggest the following change:

 

if (par5Entity instanceof EntityPlayerMP)

{

  // All the code from line 46 untill line  54.

}

 

Now that I read the whole file, I notice that you ahve this check on line 42 but the code is not inside it, so you just need to move the whole code block into the if block

thankyou silly mistake of mine

[Mazetar]

One often get blind by one's own code, it's hard to see simple mistakes when it's your own code

You might want to check up on how a stack trace can help you with debugging, just the few lines that indicates which lines crashed it and why helps you a lot inn finding such problems
