[1.6.4] Spawned entity not running onUpdate

[lexwebb]

So, I'm trying to use a custom entity to render lasers, i have entity variable syncing working using the datawatcher and my client seems receiving the necessary coordinates for its laser rendering, however my onUpdate never gets called for this entity, so none of my code ever gets hit. What am i doing wrong?

 

Entity is spawned from inside a TileEntity (My Laser)

if (!worldObj.isRemote){
laserBeam();
}

public void laserBeam(){

if(laserToList != null && laserToList.size() > 1){
	for(int j = 0; j < laserToList.size() - 1; j++){
		ForgeDirection or = laserToDirection.get(j);			

		System.out.println("spawningLaser");
		EntityBeam beam = new EntityBeam(worldObj, laserToList.get(0), laserToList.get(1));
		worldObj.spawnEntityInWorld(beam);
                	beam.updateDataServer();
                
                	laserToList.clear();
	}
}
}

Main Mod Class

EntityRegistry.registerModEntity(EntityBeam.class, "EntityBeam", 23, this, 128, 1, false);

 

If there's any more code you need to see you can find it on my GitHub https://github.com/lexwebb/opticraft

EntityRegistry.registerModEntity(EntityBeam.class, "EntityBeam", 23, this, 128, 1, false);

Using "EntityBeam.class" grabs a compiled class file not a java file, I think you need to just use "EntityBeam" (w/o the quotes).

or

EntityBeam.java (which I don't think is right)

@lexwebb, Sorry wasn't thinking 100% my bad. Still new to modding.

@diesieben07 When i tried using the inherited datawatcher i was getting NULL pointer exceptions thrown on the very first line i tried to use it. When debugging, i found that nothing was NULL, so i had no idea what was going on. I then decided to implement the datawatcher how i found in a tutorial which seemed to resolve the errors. I'll have a closer look at it.

 

Even still, the fact the the datawatcher may not work does not explain the fact that my entity does never update.

Welp i found he source of the datawatcher null pointers i was having. You can ignore that bit
