Adding a New Entity - Invisible? Texture Error?


MoonMax

Recommended Posts

So, I'm basically trying to [for starters] make a mod to add a Ball of Yarn that cats will play with. I haven't added any code for the cats to actually play with it, mostly because I can't figure out how to get it to render at all. In fact, I can't even get the icon for the item used to spawn it to render; it returns to the default iron helmet icon. Any help would be much appreciated.

The block.png and items.png are just generic testing sheets, I shouldn't have them referenced anywhere.

 

 

↑It makes sense if you don't think about it.↑

 

Creepers only explode because they want to hug you, but when they reach you, they realize they have no arms, and then explode with anger.

In the item.java u add an extra 's' at the method name:

 

public String getTextureFiles()
{
  return CommonProxy.ITEMS_PNG;
}

 

Try:

 

public String getTextureFile()
{
  return CommonProxy.ITEMS_PNG;
}

 

Also you didn't call the right image files in the commonProxy.java. I'm sure this will fix the "texture not loading" problem... at least for forge 6.3.0 (mc 1.4.4).

    • Okay so we tried both versions and both cant run on her pc for some reason!  
    • Well. Make sure you installed a correct jdk for your forge mdk version. Make sure your JAVA_HOME and %PATH% environment-variables are setup correctly. (If you're on windows)   I downloaded an example forge mdk for my version and extracted the contents to a folder I'm working in Using Eclipse, I opened Eclipse and imported an existing gradle Project (with its root directory in the folder directory which I previously extracted my contents to). Waited for Eclipse to do its thing After it having finished, I ran genEclipseRuns, setupDecompWorkspace and setupDevWorkspace (Gradle Tasks > your mod name here > forgegradle)    If it still didn't work (and you're using Eclipse) run cleanEclipse and, in a command prompt  Also If I recall correctly, someone, somewhere said that the way you setup your workspace changes depending on your Minecraft Version. I did this in 1.8.9.
