White TNT Entity? Rendering Help!

Thank you, and I realize that I'm probably missing something huge.

Look over at some stuff, I though:

I don't need to use a model, it has the right shape already?

Am I correct?

[SanAndreaP]

I suspect that your fuse counter (variable within your entity class) does only change within the serverside scope, which means the fuse won't be visible to the client and thus rendering your entity white all the time.

You need to sync the fuse with the client and the easiest way to do this is to use a DataWatcher.

Define a new DataWatcherObject (with this.dataWatcher.addObject(...)) within entityInit

on the server side (if worldObj.isRemote == false) set the object's value to the fuse variable in your onUpdate method after it gets updated with dataWatcher.updateObject(...)

on the client side (if worldObj.isRemote == true)  set the value of the fuse variable to the dataWatcherObject's value with getWatchableObjectInt(...)

 

If you don't understand what I mean, here have some pseudocode:

Entity Class
----------
entityInit():
    dataWatcher->addObject(id, Integer.valueOf(0))    | id must be unique! If you get a crash because an already given ID, try another one
                                                      | second param must be casted to the datatype you wanna put in there, here Integer (BTW, the cast is not pseudocode)

onUpdate(): (at the end within the method)
    if world is not remote:
        dataWatcher->updateObject(id, fuse)    | id must be the same as the above defined one
    else:
        fuse = dataWatcher->getWatchableObjectInt(id)    | id, same as above

[Cookie160]

Thank you, you make a great point, but, where exactly in the code should this Data Watcher go?

[SanAndreaP]

Thank you, you make a great point, but, where exactly in the code should this Data Watcher go?

 

Every entity has already a dataWatcher instance. Everything else is explained in my previous post.
