I have found the following class.

package net.minecraftforge.client.model;
public final class ModelLoader extends ModelBakery {
	private static final class WeightedRandomModel implements IModel {
		private final List<IModel> models;
	}
}

 

I have an IModel object and I would like to access the models field. To do this, I must cast the object to ModelLoader.WeightedRandomModel.

How can I modify WeightedRandomModel to be public?

 

I have had no success with reflection or access transformers so far.

I am not familiar with reflection. How would I do something like this with reflection?

public void doSomething(IModel model) {
	WeightedRandomModel wModel = (WeightedRandomModel) model;
	List<IModel> list = wModel.models;
	//Do something with list
}

 

Can you provide an example?

At runtime the variable models holds all the data for all blocks in the game. I am attempting to write a rendering engine, and I need the shape of the blocks to do this.

 

The interface IModel has 3 classes that implement it. Only one of these contains the variable 'models'. I have verified that 'model' is of the class 'WeightedRandomModel'. The compiler informs me that 'WeightedRandomModel' is not visible and I can't cast 'model' to it. I have read the reflect tutorial, but it doesn't seem to help my situation. Class.cast() deosn't seem to do what I want either.

WeightedRandomModel wModel = (WeightedRandomModel) model; //Compiler error

 

I would like to read all of the data in 'models', but I don't know how to access it.

When I use

Class c = model.getClass();
c.getDeclaredField("models").setAccessible(true);
c.getDeclaredField("models").get(model);

it throws

java.lang.IllegalAccessException: can not access a member of class net.minecraftforge.client.model.ModelLoader$WeightedRandomModel with modifiers "private final"

It looks like you've solved the Forge mysteries and need Java help. Search online for how reflection is used to access private fields.

 

If you want to learn how Forge might reach your goal via a different route, then tell 7 what you are aiming for.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

It appears that I'm an idiot (or shouldn't code when tired).

 

I have since discovered a forge event in a nearby class that appears to provide the same information.

 

Thanks for the help.

    • Hello all. I'm currently grappling with the updateShape method in a custom class extending Block.  My code currently looks like this: The conditionals in CheckState are there to switch blockstate properties, which is working fine, as it functions correctly every time in getStateForPlacement.  The problem I'm running into is that when I update a state, the blocks seem to call CheckState with the position of the block which was changed updated last.  If I build a wall I can see the same change propagate across. My question thus is this: is updateShape sending its return to the neighbouring block?  Is each block not independently executing the updateShape method, thus inserting its own current position?  The first statement appears to be true, and the second false (each block is not independently executing the method). I have tried to fix this by saving the block's own position to a variable myPos at inception, and then feeding this in as CheckState(myPos) but this causes a worse outcome, where all blocks take the update of the first modified block, rather than just their neighbour.  This raises more questions than it answers, obviously: how is a different instance's variable propagating here?  I also tried changing it so that CheckState did not take a BlockPos, but had myPos built into the body - same problem. I have previously looked at neighbourUpdate and onNeighbourUpdate, but could not find a way to get this to work at all.  One post on here about updatePostPlacement and other methods has proven itself long superceded.  All other sources on the net seem to be out of date. Many thanks in advance for any help you might offer me, it's been several days now of trying to get this work and several weeks of generally trying to get round this roadblock.  - Sandermall
    • sorry, I might be stupid, but how do I open it? because the only options I have are too X out, copy it, which doesn't work and send crash report, which doesn't show it to me, also, sorry for taking so long.
    • Can you reproduce this with version 55.0.21? A whole lot of plant placement issues were just fixed in this PR.
    • Necro'ing that thread to ask if you found a solution ? I'm encountering the same crash on loading the world. I created the world in Creative to test my MP, went into survival to test combat, died, crashed on respawn and since then crash on loading the world. Deactivating Oculus isn't fixing it either, and I don't have Optifine (Twilight forest is incompatible)
