[1.7.10] Attempting to code with ASM transformer. Unable to launch


Recommended Posts

Posted

I tried to learn about access transformers. I coded a few classes and I was about to test it, but I was unable to launch Minecraft at all and it doesn't seem the error comes from my injection.

I ended up with ClassNotFoundException with net.minecraftforge.transformers.ForgeAccessTransformer and weirdly I can find the class in the forge Jar.

Here's my run configurations:

VM args: -Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.coreMods.load=com.ringosham.transform.TransformerPlugin

Program args: --version 1.7.10 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --accessToken modTest --userProperites {} --username Ringowhs --assetIndex 1.7.10 --assetsDir C:\Users\*USERNAME*\.gradle\caches\minecraft\assets

Here's the whole error. I tried refreshing dependencies with gradle and it still doesn't work. This mod originally does not use transformers at all and it runs well in Eclipse. I probably did something stupid that I don't know, but please help me.

Why are you trying to edit classes?

I was trying to intercept any outgoing chat messages by changing the EntityClientPlayerMP.sendChatMessage

I know that there is a way to do that with some networking(or SimpleNetworkWrapper/netty/whatever) stuff as you told me before, but the methods I found in the tutorials doesn't seem that there are answers. I found tutorials about sending and receiving packets from and to servers, but I cannot seem to find anything from catching outbound packets.

    • So am trying to make a custom 1.19.2 modpack and everything works until I add Oculus. I have tried Oculus+Embedium and Oculus+Rubdium and by themselves they work but as soon as I add anything it crashes no matter what it is. The modpack works fine with just Embedium and Rubdium. Can you help me to see if this is something i can fix or do i just have to deal with not having shaders. Here is the crash log. Thank you for your time. https://paste.ee/p/WXfNZ24K

    • What do I do now when it says "1 error"?
    • Hello everyone new here how are you all?
    • I haven't tested it but under https://minecraft.wiki/w/Items_model_definition it says now:   So I guess the resource location must have changed with 1.24.4, which means you need to move your models/item/ to the new source. But as I said I haven't tested this so it also may be that this wont work. Nevertheless give it a try      EDIT (important) So now I tested it and found out how it works   Let the model files (e.g. the .json from blockbench) within "assets/<your_mod_id>/models/item" In addition to that do the following: Every model you added will need a new file under "assets/<your_mod_id>/items" That file is also a JSON and looks like this: { "model": { "type": "minecraft:model", "model": "your_mod_id:item/custom_item" } } - "type" can be minecraft:model, minecraft:composite, minecraft:condition, minecraft:select, minecraft:range_dispatch, minecraft:empty, minecraft:bundle/selected_item or minecraft:special. (In most cases you would need minecraft:model) - "model" is the path to your actual model for this item. For example the value above would point to "assets/your_mod_id/models/item/custom_item"
