A library of functions to help with ASM transformations in Minecraft mods
With Forge > 1.14, Forge CoreMods are now implemented in Javascript. This branch is a port of ASMHelper from Java to Javascript in order to make it easier to port mods that used ASMHelper to 1.14+.
To use the Javascript version, put asmhelper.js in your mod's resources directory and load it in your initializeCoreMods function like so:
function initializeCoreMod() {
Java.type("net.minecraftforge.coremod.api.ASMAPI").loadFile("path/to/asmhelper.js");
// ASMHelper is now an object in the global namespace
return {
"FoodStatsTransformer": {
"target": {
"type": "CLASS",
"name": "net.minecraft.util.FoodStats"
},
"transformer": function(classNode) {
var internalClass = ASMHelper.toInternalClassName("some.package.IClassName");
classNode.interfaces.add(internalClass);
return classNode;
}
}
}
}Some methods that existed in the Java version have not been ported to Javascript. This is either because they are no longer applicable or they simply were not used by AppleCore and so porting them was not worth the effort. Pull requests for any unported functions are welcome!
