[1.7.2]Is there a way to "redirect" methods of an existing vanilla class?

I'm writing a mod to create wood fences for all the different types of wood in minecraft, but I want them all to connect to each other. It was easy enough to override the fences' canConnectFenceTo() methods, so now the only one left is the vanilla fence. Is there a way to override or circumvent the vanilla fence's canConnectFenceTo() method so that it connects to the other fences?

 

I have just begun learning mincraft modding, but I know Java pretty well. I'm just used to creating my own projects from scratch, and far less experienced working around someone else's code.

 

Thanks in advance.

Firstly, if your fence classes extend the vanilla fence class then the vanilla fence class will consider them fences.

 

Secondly, if there is a cancellable event at the time of interest you can intercept it by subscribing to it and doing your own processing.  Like maybe when player places a block you could intercept it.

 

Thirdly you can replace the vanilla block with your own that extends the vanilla block but overrides the methods you want to customize.  You can do the replacement by maybe changing the crafting recipe for the fence to output yours instead, or you can look for any instances of fence and simply replace them with yours, and so forth.  Not necessarily elegant but possible.

Thanks for the reply, jabelar. My fence class does extend the vanilla fence, however, it doesn't seem to recognize a child of the BlockFence class as a Block.fence, and therefore the method mentioned above returns a false boolean.

 

Your second suggestion might solve my problem, but I have yet to look into tapping into subscribing to game events, and am unfamiliar with how minecraft handles player events. I'll check this method out, thanks!

Yeah, the problem is the way it checks if it is a fence.  If it had checked the class using isMemberOf then your blocks would be considered fences, but since it is checking specifically against the registered instance then yeah that won't work.

    • Hello, Hi and I am making a forge 1.12.2 mod and also trying to get a custom model helmet item (I made a joker mask) and exported it to .json format and put it in the ~/namespace/models/item folder. Though, I'm struggling to get the item to render what I want it to be rendered like as I've positioned it in the 'head' window view in blockbench. How did you render out your model? I checked your code and it looks like no references to the actual model are being made. I'm new to this forge modding stuff (was a fabric modder) and I desperately need some help. Is there a way to standardly render out armor models made using blockbench? any methods that one can use? My model in JSON: ```json { "credit": "Made with Blockbench", "texture_size": [160, 160], "textures": { "0": "ydyrn:items/joker_mask_texture", "particle": "ydyrn:items/joker_mask_texture" }, "elements": [ { "from": [0, 0, 0], "to": [16, 16, 1], "faces": { "north": {"uv": [0, 1.7, 16, 14.2], "texture": "#0"}, "east": {"uv": [0, 4, 0.9, 5.6], "texture": "#0"}, "south": {"uv": [0, 5.8, 1.6, 7.4], "texture": "#0"}, "west": {"uv": [0, 1.9, 1.3, 3.5], "texture": "#0"}, "up": {"uv": [0, 3.4, 1.6, 4.2], "texture": "#0"}, "down": {"uv": [0, 9, 1.6, 9.7], "texture": "#0"} } }, { "from": [15.8, 11, 0.5], "to": [16.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } }, { "from": [0.2, 11, 14.6], "to": [15.8, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"} } }, { "from": [-0.2, 11, 0.5], "to": [0.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } } ], "display": { "thirdperson_righthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "thirdperson_lefthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "firstperson_righthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "firstperson_lefthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "ground": { "rotation": [40, 0, 0], "translation": [0, -2.5, 0], "scale": [0.5, 0.5, 0.5] }, "gui": { "rotation": [0, 180, 0] }, "head": { "translation": [0, 0, 0.25], "scale": [0.82773, 0.73594, 0.9] }, "fixed": { "translation": [0, 0, 8.75] } }, "groups": [ 0, { "name": "straps", "origin": [0, 0, 0], "color": 0, "children": [1, 2, 3] } ] } ```
