[Solved] [1.13.2] Schedule Code to be Ran Later


DavidM

Recommended Posts

In my TileEntity#read, I am trying to do the following:

@Override
public void read(NBTTagCompound nbt) {
	super.read(nbt);
	
	/*... getting fields from nbt*/
	
	if (this.world.isRemote()) this.updateModel(); // Used by tesr. Must be called after getting fields from nbt is done.
	this.power = this.world.getRedstonePowerFromNeighbors(this.pos);
}

 

As shown in the code, the last two lines all require access to World; however, when TileEntity#read is called as the world initializes, TileEntity#world is null, and therefore the last two lines will encounter a NullPointerException.

My idea is that I can somehow schedule the lines that refers to TileEntity#world to be ran later when the world finishes loading. How would I achieve that?

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

TileEntity#onLoad is the same as checking if the tick is the tiles first tick, but indicates your intention better

Versions below 1.14.4 are no longer supported on this forum. Use the latest version to receive support.

When asking support remember to include all relevant log files (logs are found in .minecraft/logs/), code if applicable and screenshots if possible.

Only download mods from trusted sites like CurseForge (minecraft.curseforge.com). A list of bad sites can be found here, with more information available at stopmodreposts.org
