translating parts of a string for display in chat?

[stepsword]

I have a string like this: "key.abc, key.def!!!"

In the lang file, I have

key.abc=Hello

key.def=World

 

How do I get this to show Hello, World!!! when printed? I tried doing  "" + new TextComponentTranslation("key.abc") + new TextComponentTranslation("key.def") + "!!!" with no luck. Sadly those objects when printed just give an overview of the object rather than the actual translation. Is there a built-in way to get the translation?

Translations are applied later so by string concatenating you aren't applying a translation. So instead use a method on TextComponentTranslation to add a sibling or a child not sure what it is in this case. Then call getFormattedText()

Thanks, I will look into siblings and children
