Hello! I have recently upgraded to the new Forge and MC 1.3.2. However, I can not get this one little bug squashed!

 

Here is the error log:

and here is the effected lines:

 

public void onUpdate()    
{  
   super.onUpdate();        
   if(riddenByEntity != null)
   {
       EntityPlayerSP entityplayersp = (EntityPlayerSP)riddenByEntity;
       double uplift = 0.45500000000000002D;
       if (entityplayersp.movementInput.jump)
       {
    		  motionY = 0.1D;
       }

       if (entityplayersp.movementInput.sneak)
       {
              motionY = -0.1D;
       }

That riddenByEntity variable is a EntityPlayerMP object. However, you are trying to cast it to a EntityPlayerSP, which is impossible. Try to use another way

IIRC, functions like that get called twice- once with a EntityPlayer, and once with a EntityPlayerMP (or something like that.) But I'm not sure if that'll help.

 

What about registering key-bindings?

Dude, the registering is probably fine, because if you look at the crashlog, it'll tell you that he's trying an invalid type-cast. That's probably his main problem now.

Thanks for the help so far! However, I do still have a problem with EntityPlayerMP casting into itself for that line:

BTW, I changed the ascending and descending by using this code (this also includes the most current code):

EntityPlayerMP entityplayermp = (EntityPlayerMP)riddenByEntity;
       double uplift = 0.45500000000000002D;
       /*
       if (entityplayersp.movementInput.jump)
       {
    		  motionY = 0.1D;
       }

       if (entityplayersp.movementInput.sneak)
       {
              motionY = -0.1D;
       }
       */
       motionY = riddenByEntity.motionY * uplift;

 

Should I try keybindings? If so, could you direct me to a good tut?

java.lang.ClassCastException: net.minecraft.src.EntityClientPlayerMP cannot be cast to net.minecraft.src.EntityPlayerMP

Have you read this very carefully? Because you would've noticed that this doesn't cast to itself, but it casts a EntityClientPlayerMP to a EntityPlayerMP (see the Client in the first one?) I have no idea how to fix this though...

Ya. I also tried EntityPlayerClientMP, or whatever it was that was mentioned in this post above, and it gave me the exact same error, which is peculiar.

have you tried just EntityPlayer?

Ya I think I fixed it for the controlling for the most part, but now I am just getting a packet error - the server suspects cheating?

Maybe you should add a check to make sure there isn't a NullPointer. Thid line: EntityPegasus.java:110 has an error, because you try to use a variable which holds the value "null". Just make sure it isn't null when you use it, like so:

if(var != null) {
    // Code Here 
}
