[1.12.2] How to translate parts of custom entity up and down? [SOLVED]


Recommended Posts

I have been able to successfully rotate specific parts of my custom entity, using Block.rotateAngleY within this method of the model class:

public void setLivingAnimations(EntityLivingBase entityIn, float limbSwing, float limbSwingAmount, float partialTickTime)


Now I'm trying to figure out how to move specific parts up and down. Using the same method above, I tried using Block.offsetY, but it has absolutely no effect. Any ideas on how I can translate specific sections of my entity?

In your model class you should be able to change the position of each box part. Note that changing offset will change the rotation point within the block -- it will appear to move but will also rotate differently. Changing the pos will move the whole thing and keep the rotation point in same location.


In any case can you post your whole code, at least for the model class?

My model consists of a center that I would like to rotate and spin independently of the rest of the model. Right now, it's able to spin using rotateAngleY and values from a capability that stores an increasing int every tick after a player interacts with the entity. I would like to have the center similarly move up and down as well. 


Here is my long model file:

Wow, that's a pretty crazy model (in terms of there is a lot of boxes).


Instead of changing the offset I think you need to use the setRotationPoint() method. That is what places the rotation point in 3D space relative to the entity position.


The way it works, if I remember correctly is:

1) You create a box by specifying the size in x, y, z.

2) You also specify the offset which is the point WITHIN the box where rotation occurs.

3) You then need to specify the rotation point which is actually placing the block in space. 

4) You can then set rotation angle (around that point).


Note that I believe that the naming of the methods is sort of misleading. You would think that setting the rotation point would imply setting the point within the block where it rotates; but it is the opposite, the offset does that and the set rotation point actually moves the whole block.


Anyway, that is what I remember from when I used to do complicated animations.


Also, for easier debugging you might want to try a much simpler model. Like maybe just make one block that you can control up and down first.

    • हथियार व्यापारियों की चमक आज के समय में भारत और दुनिया के विभिन्न हिस्सों में तेजी से बढ़ रही है। स्वीडन की स्थित संस्था सिपरी की नवीनतम रिपोर्ट के अनुसार, विश्व भर में विभिन्न देश अब पूर्व कभी नहीं देखे गए हथियारों और सैन्य सामग्रियों पर धन का व्यय कर रहे हैं। वैश्विक संघर्षों के बढ़ते संकेतों के कारण, विश्व के कई हिस्सों में युद्ध की संभावनाएं बढ़ रही हैं। पश्चिमी एशिया में युद्ध की आग फैल रही है, जबकि दक्षिण चीन सागर और ताइवान में भी तनाव बढ़ रहा है। भारत-चीन सीमा पर भी स्थिति चिंताजनक है। इन घटनाओं के परिणामस्वरूप, विभिन्न देशों की प्राथमिकताएं बदल रही हैं, और हथियार व्यापारियों का धंधा आजकल चमक उठा है। सिपरी की रिपोर्ट के अनुसार, 2023 में वैश्विक सैन्य खर्च एक नया रिकॉर्ड स्थापित किया गया है। 2022 की तुलना में, 2023 में सैन्य खर्च 6.8 फीसदी बढ़कर 24.4 ट्रिलियन डॉलर पर पहुंच गया। इसके पीछे कुछ विशेष कारण हैं, जिनमें दुनिया भर में तनाव बढ़ना और अद्यतित सैन्य तैयारियों की आवश्यकता शामिल है। इस वृद्धि में, भारत जैसे देशों का योगदान भी अधिक है। भारत ने भी अपने सैन्य खर्चों में वृद्धि की है, और यह दुनिया के सबसे बड़े और सबसे प्रभावशाली राष्ट्रों में एक बन गया है। इसके अलावा, अमेरिका, चीन, और रूस भी सैन्य खर्च में वृद्धि की हैं, जिससे विश्व सुरक्षा में नए दायरे खुले हैं। संभावनाओं के इस नए मंच पर, दुनिया के सक्षम देश अब अपने सैन्य तैयारियों में ज्यादा ध्यान दे रहे हैं। यह वृद्धि विकास और प्रगति के बजट पर भी प्रभाव डाल रही है, जिससे विभिन्न देशों के आर्थिक प्रगति में बदलाव आ सकता है।   https://www.nayaindia.com/editorial-column/editorial1/arms-sales-increased-in-the-world-454072.html
    • 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] } ] } ```
