}

IDE是 IntelliJ IDEA ，不知道为什么不显示

错误提示已经写的很清楚了。

java.lang.IllegalStateException: No renderer registered for specialitem:suicide_bomber

你没有注册render，你有代码忘记抄了。

我再试试

看了视频教程，其中也没有提到注册render的方法。算了，这个添加实体的项目暂时废弃。

那就奇怪了，我就是这样照着添加了，但是init显示灰色，ClientProxy也是显示灰色的。而且我照着格式输入，就会显示错误，改成：

RenderingRegistry.registerEntityRenderingHandler(EntityHelper.SUICIDE_BOMBER, EntityRenderer::new);

才不会报错，但是依旧不行。

显示的错误为：

reason: no instance(s) of type variable(s) T exist so that Class conforms to EntityType

是写成

RenderingRegistry.registerEntityRenderingHandler(SuicideBomber.class, EntityRenderer::new);

会报错。

灰色？ ClientProxy 你没用 DistExecutor#runForDist吗？
报错，什么报错，报错信息呢？
还有请学一下markdown，好好的贴代码。

报错信息

reason: no instance(s) of type variable(s) T exist so that Class conforms to EntityType

代码要用三个「`」包裹……
你这是什么东西的报错信息。
请粘贴完整的错误信息。

就是底下的那行字。

当然是错的……拜托你看清楚参数类型再填参数好吗？
第一个参数的要求类型是EntityType<T>好不好……你填了一个什么东西进去。

你用DistExecutor#runForDist初始化你的ClientProxy过了吗？

实在注入不进去用Minecraft.getInstance().getRenderManager().register();这个方法试试。
这个方法是肯定可以注入进去的，如果用这个方法还是无效，说明你是别的地方写错了。

我再试试。

你先确定你的ClientProxy类有初始化，把你的主类的代码粘贴上来看看。

就是所添加实体的代码吗？

不是，你的@Mod()注释所在的类。

你根本没有初始化ClientProxy这个类，当然是灰色的，当然是没有用的。

要用DistExecutor.runForDist初始化Proxy。

添加了，我再试试看。再不行的话，全部废弃重新再弄一次，就不信弄不好一个实体。
