[ 1.7.10 ] Where is the null point exception?

[Guebeul]

Hi, I'm going to ask a question.
I'm implementing the player's movements through the Obsidian API. But there was a problem..

1. first person


2. Third person

 

In this way, the player is invisible when you are in third person, and it emits the following error. (Repeat continuously)

These two pictures are CommonProxy and ClientProxy I touched.
1. CommonProxy


2. ClientProxy

 

As noted in the log, NullPointerException is a problem. I really wonder where this NullPointerException happens.

RenderPlayerAnimated: https://github.com/ObsidianSuite/ObsidianSuite/blob/master/API/src/main/java/com/dabigjoe/obsidianAPI/render/player/RenderPlayerAnimated.java
ModelAnimatedPlayer: https://github.com/ObsidianSuite/ObsidianSuite/blob/master/API/src/main/java/com/dabigjoe/obsidianAPI/render/player/ModelAnimatedPlayer.java

 

If you know where NullPointerException is happening, the developer can help.
Please help me...!

Anything below 1.8 is unsupported on this forum update if you want help. Soon 1.8.9 support will also be dropped if it isn't already. A Moderator will lock this thread later.

You can not ask questions below version 1.8? It's really important that it is ...

Other forums will answer this question, it just makes it difficult to answer questions on older versions because supporting the massive changes between 1.7 and 1.8 and the changes between every other version that changed some core system. Would you expect Mojang to go back and update 1.7 versions to fix a bug or Oracle to go back to Java 6 to add new features? Or supply support? No. That is why other places exist. What makes your reason so important?

Anyway, a null pointer is a Java problem, not really a modding problem. It means that at that point in the code, something is null when it is not expected to be. Just use your debugger or console statements to trace through the execution leading up to that point in the code. Basically the error message tells you what is wrong so now up to you to fix it.
