Customize max farming slope

[joedobo 1,187]

I saw someone request this elsewhere. I don't want to maintain Javassist/Hookmanager based mods so wrote the code and am putting it here.

 

In addition to the code below, which handles sowing, you'd need to make something almost identical for the TileFieldBehaviour.class so raking is possible. All you need to do is copy the code and change the CtClass's path to reflect "com.wurmonline.server.behaviours.TileFieldBehaviour".

public void configureMaxSowingSlope(int customMaxSlope){
	try {

		CtClass ctClassTileDirtBehaviour = HookManager.getInstance().getClassPool().get(
				"com.wurmonline.server.behaviours.TileDirtBehaviour");
		CtClass returnType = CtPrimitiveType.booleanType;
		//Action act, Creature performer, Item source, int tilex, int tiley, boolean onSurface, int heightOffset,
		//   int tile, short action, float counter
		CtClass[] paramTypes = {
				HookManager.getInstance().getClassPool().get("com.wurmonline.server.behaviours.Action"),
				HookManager.getInstance().getClassPool().get("com.wurmonline.server.creatures.Creature"),
				HookManager.getInstance().getClassPool().get("com.wurmonline.server.items.Item"),
				CtPrimitiveType.intType, CtPrimitiveType.intType, CtPrimitiveType.booleanType, CtPrimitiveType.intType,
				CtPrimitiveType.intType, CtPrimitiveType.shortType, CtPrimitiveType.floatType
		};
		CtMethod ctMethodAction = ctClassTileDirtBehaviour.getMethod("action",
				Descriptor.ofMethod(returnType, paramTypes));
		ctMethodAction.instrument(new ExprEditor() {
			@Override
			public void edit(MethodCall methodCall) throws CannotCompileException {
				if (Objects.equals("isFlat", methodCall.getMethodName())) {
					methodCall.replace("{ $4 = "+customMaxSlope+"; $_ = $proceed($$); }");
				}
			}});
	} catch (NotFoundException | CannotCompileException e){
		logger.warning(e.getMessage());
	}
}
