NullPointerException when using getModelColors

[jawa 4]

So I'm trying to identify a gameObject by getModelColors().

GameObject xx = getGameObjects().closest(o -> o.getModelColors()[0] == 2555);

However, this throws me a nullpointer exception. I've also tried passing it through a filter, no luck.

The gameObject can be null as well as the modelcolors array, you need to null check them beforehand:

GameObject xx = getGameObjects().closest(o -> o != null && o.getModelColors() != null && o.getModelColors().length > 0 &&  o.getModelColors()[0] == 2555);

Thanks for your help. However it still throws me a nullpointer..

Ah silly me... I never checked if the modelColors array was null, only the object itself.

It works now, thank you once again!

I found that when setting up the script for mining, it was faster and had better results when searching for the ID numbers of the rocks opposed to the color.  Also had far less trouble with the null pointer exception issue which was happening when trying to check the color of an empty rock.  Just be careful when using ID numbers - I've found that each type of ore has at least two different ID numbers.  It's an easy way to get detected if you're only mining the one ID.
