[Solved] Mobs won't animate


Recommended Posts

I've made a custom mob, I've got the entity file, the render file and the model file

I know the render file is rendering the model because I added extra objects that are showing up

The only trouble is my mobs won't animate

They won't walk, they just jump from place to place after lagging for about 10 seconds


I've looked over ever entity, render and model file in vanilla to find out what I'm missing, I've checked over the code at least a hundred times, everything is how it should be, I just can't work out what's missing


I'll add the code for the three files below


Render File


package deadworld;

     * (Render<T extends Entity) and this method has signature public void doRender(T entity, double d, double d1,
     * double d2, float f, float f1). But JAD is pre 1.5 so doesn't do that.

Part in the main file where I registered the entity and render


	EntityRegistry.registerModEntity(EntityDemon.class, "Demon", 2, this, 42, 252, true);
	EntityRegistry.addSpawn(EntityDemon.class, 100, 1, 2, EnumCreatureType.monster, Deadworld.deadBiome);
	LanguageRegistry.instance().addStringLocalization("entity.EntityDemon.Deadworld.name", "Demon");

	RenderingRegistry.registerEntityRenderingHandler(EntityDemon.class, new RenderDemon(null, 0));



So, unless I'm, literally, missing another file that animates the mob, I have no idea what I'm missing and if it is another file, I have no idea which it is


Any help would be appreciated, because I'm officially out of ideas

... you know those moments where you're very happy but also want to scream because the solution was so simple?


I'm having that now


Thank you

That worked :D

In which case, what was the number you used? That would be nice, because I don't really know; I was just guessing and I need help with entities myself.

I lowered it incrementally

... tbh I don't even know why it was so high

in the end I just used 1


so it's


EntityRegistry.registerModEntity(EntitySpiritMob.class, "Spirit", 1, this, 41, 1, true);


It was kinda jumpy at 10 but a lot better, so I imagine 1 - 5 would work nicely

    • I've been trying to give a little transparency to a block and a custom model, but I'm running into the same issue with the transparency of the block Some guides say I use ItemBlockRenderTypes.setRenderLayer in a ClientEvent class but its deprecated, I already tried to set a Properties in Properties.copy(Blocks.FLOWERPOT) But the render in game still doesn't has transparency, only as an Item  
    • My friends and I are modding to survive But recently I want to use cmd to open the server instead of making the single player game public But when I used two methods to start the server, I encountered two problems first A I used forge to install the server files Created using the original server jar The server was installed successfully and the mod was also loaded successfully. But after I replaced the world file with my survival map, I found that the mod items inside disappeared but could be taken from creation again. So I tried to install the server using forge first B I have studied forge for a long time but successfully installed it. But when I put in mods it crashed But mods can be installed on the server   我和我的朋友們正在mod為了生存 但是最近我想用cmd打開伺服器而不是把單人遊戲公開 但是當我使用兩種方法啟動伺服器時,我遇到了兩個問題 首先AI使用forge安裝伺服器檔案使用原始伺服器jar 建立伺服器已成功安裝,mod 也已成功載入。但是當我用我的生存地圖替換世界文件後,我發現裡面的mod物品消失了,但可以再次從創建中取出。所以我嘗試先使用forge安裝伺服器,BI研究了forge很久但成功安裝了它。但是當我安裝 mods 時它崩潰了但是 mods 可以安裝在伺服器上 我和我的朋友正在mod生存 但最近我想使用cmd開啟伺服器而不是單人遊戲公開   但是當我使用了兩種方法開啟伺服器時遇到了兩種問題   第1個A 我使用了forge安裝伺服器文件 在使用原版伺服器jar建立    伺服器安裝成功 mod也順利加載  但是我將我的生存地圖替換世界文件後發現裡面的mod物品消失了但可以再次從創造拿取  所以我嘗試使用forge安裝伺服器   第2個B forge我研究了很久但也成功安裝了 但是當我放入 mods 之後發生了崩潰 但是mods在1A伺服器上是可以安裝的 Ps 我用谷歌翻譯 so    
    • That’s probably not it because as I stated I’ve done it before. I did it like deadass 10 - 20 times when trying to learn to make this mod pack because I kept wanting to reset my profiles and such. So it definitely works, it looks like maybe the creephosting files were the things that couldn’t be reached I tried reading the crash log
    • I don't know if this is the right place or not, but I have put together a custom modpack and I am in need of others to help me. It's a questing modpack with a lore book i'm currently writing out through Patchouli, and i am in need of somebody who will assist me in making the quests for the pack. It's a Zombie apocalypse modpack inspired by Deceasedcraft  with a tinge of magic and RPG mechanics via Mine and slash. Is there anybody willing to assist me as i'm one person building a modpack I could also use help with optimizations since that's not really my strong suite.
