[1.9.4] ASM how to get a private value from a class


perromercenary00

Recommended Posts

 

 

 

good days im trying to solve and old trouble and for this i need to know basic asm

 

the thing is this i need to get the float value from a private varible from a class two know what is internally happend

 

exactly i wanna see    "private float equippedProgressMainHand;"  from a runing instance of:

net.minecraft.client.renderer.ItemRenderer.java

 

 

to do this im doing client side of course

 

 

 

			Minecraft mc = Minecraft.getMinecraft();
			EntityPlayer playerIn = mc.thePlayer;
			ItemRenderer IR = mc.getItemRenderer();

			try{
				float a1=0.5F;
				{

					Field field = ItemRenderer.class.getDeclaredField("equippedProgressMainHand");
					field.setAccessible(true);


					Float f = field.getFloat(field);

					System.out.println("f="+f);
					//field.setFloat(IR,a1);
				}

 

well seems like this is not the right way to observe a float value throght reflection methods

i been trying diferents things from google today but just get and error here or there in other test it wass something about the field is privated

 

in the other hand field.setFloat(IR,a1); seems to works  but i need to know first whath are the values i gonna force here

coz sething this float a1=1.0F;  to  1.0F just cause the item to go up in first person view

and sething this float a1=0.5F; causes the item to slowing go down

The argument of

Field#getFloat

(and the other

Field#getX

methods) is the instance to get the field's value from. In this case, the

ItemRenderer

instance. Don't pass the

Field

as an argument.

 

Your current code won't work in the release (obfuscated) environment because there won't a field called

equippedProgressMainHand

. Instead, it will have an SRG name like

field_0013_a

(use MCPBot to find the actual name). This means you need to check both names, FML's

ReflectionHelper

provides some useful methods for this.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

You are doing Reflection, not ASM.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Are we talking about assembly here? Or ASM stands for something else?

 

Also I'm pretty sure you are doing reflection.

 

ASM is a library for manipulating Java bytecode. Minecraft and Forge use it, but mods should avoid using it where possible.

well thanks for aclaration

 

i been able to read the data whith reflecction

 

	// ############################################################################################3
@Override
public boolean shouldCauseReequipAnimation(ItemStack oldStack, ItemStack newStack, boolean slotChanged) {

	Boolean b = oldStack.equals(newStack);
                Boolean showValues = true;


	if (showValues)
	{
	Minecraft mc = Minecraft.getMinecraft();
	EntityPlayer playerIn = mc.thePlayer;
	ItemRenderer IR = mc.getItemRenderer();

	System.out.println("#=");


	try {
		float cas = playerIn.getCooledAttackStrength(1.0F);
		{
			// this.prevEquippedProgressMainHand

			Field field = ItemRenderer.class.getDeclaredField("equippedProgressMainHand");
			field.setAccessible(true);
			float f = field.getFloat(IR);
			System.out.println(" f=" + f );

		}

		{
			Field field = ItemRenderer.class.getDeclaredField("prevEquippedProgressMainHand");
			field.setAccessible(true);
			float pf = field.getFloat(IR);
			System.out.println(" pf="+pf);
		}

	} catch (Exception e) {
		e.printStackTrace();
	}

	}


	System.out.println("B="+!b);
	return !b;

}

it makes clear why some of the things i try failed whith wicked results

 

console output cleaned

when it reaches zero the itemStatck change B becomes again false this take like three ticks 
then there goes back to 1.0F

inthe other hand i think im to young for the irc chat

a wass able to enter using the web client but is like i never get inside the channel #mcp  or de other

inside i wass the only user in th list and when try to call the bot it says then the user is not found

I don't think I had much luck with the web client, I ended up downloading HexChat to use MCPBot.

    • Bottle Cap Torque Tester: Ensuring Precision in Packaging Integrity In the packaging industry, ensuring that containers are securely sealed is paramount for maintaining product quality and safety. One of the most critical components in this process is the bottle cap, which must be tightened to a precise torque to prevent leaks, contamination, or damage. The Bottle Cap Torque Tester by Pacorr is a high-precision instrument designed to test the opening and closing torque of bottle caps, ensuring the integrity of packaging. Importance of Torque Testing for Bottle Caps Torque is the rotational force applied to tighten or loosen a cap on a bottle. Too much torque can cause the cap or the neck of the bottle to break, while too little torque can result in leaks or tampered products. This is especially important for industries like pharmaceuticals, beverages, cosmetics, and chemicals, where any packaging failure can lead to significant financial loss and harm to consumers. The Bottle Cap Torque Tester Price ensures that every cap is perfectly tightened to the desired specification, preventing such issues and guaranteeing the safety and quality of the product inside. Key Features of Pacorr's Bottle Cap Torque Tester High Precision Measurement: The tester is designed to provide highly accurate torque readings for both capping and uncapping, giving manufacturers confidence in their packaging processes. Versatility: It can accommodate a wide range of bottle sizes and cap types, making it suitable for various industries, including beverages, pharmaceuticals, cosmetics, and more. Easy Operation: With an intuitive design, this machine allows for quick and easy testing, reducing the time needed for quality control checks. Digital Display: The digital readout provides clear, precise torque values, ensuring consistency in testing and improving the accuracy of results. Data Logging: Many models come equipped with data logging capabilities, allowing manufacturers to store and analyze torque measurements for future reference and quality assurance. Benefits of Using the Bottle Cap Torque Tester Improved Product Quality: By ensuring that caps are tightened to the correct torque, manufacturers can prevent leaks and maintain product freshness and safety. Compliance with Industry Standards: The tester helps manufacturers meet industry-specific regulations and standards, ensuring that their products are safe for consumers. Cost Savings: Preventing packaging failures reduces waste and avoids costly recalls, ultimately saving the company money. Enhanced Brand Reputation: Consistent quality control enhances consumer trust in the product, fostering a stronger brand reputation in the market. Applications in Various Industries Pharmaceuticals: In the pharmaceutical industry, packaging must be tamper-proof to ensure product safety. The Bottle Cap Torque Tester ensures that child-resistant caps are securely fastened, complying with safety regulations. Beverages: For carbonated drinks, the correct torque ensures the pressure inside the bottle is maintained without leaking. This helps maintain the product's taste and quality until it reaches the consumer. Cosmetics: Packaging for beauty products often requires precise torque control to ensure that liquids or creams do not leak, preventing product waste and enhancing the user experience. Food & Dairy: Food products need to be tightly sealed to maintain freshness. Incorrect torque can lead to spoilage and contamination, impacting the safety and quality of the food. Conclusion The Bottle Cap Torque Tester from Pacorr is an essential tool for industries where packaging integrity is critical. It helps manufacturers maintain high product quality, comply with regulations, and protect their brand reputation by ensuring that every bottle cap is perfectly sealed. Whether you're in the pharmaceutical, beverage, cosmetic, or food industry, the Bottle Cap Torque Tester is a must-have for efficient and accurate torque testing.
