Learn to read stacktraces. You are adding name at com.DarktStriker.BioniCraft.dsbionicraft.preInit(dsbionicraft.java:194) to null object. You can't do that. Also this is deprecated function, so try to avoid it. Use lang files from this tutorial instead.

Well, try to cleanup this and reinstall recommended build.

Great! Thank you!

Make sure you don't have errors while gradlew setupDecompWorkspace , cause you are missing minecraft source lib. Also check your JDK.

You need net.minecraft.client.renderer.entity.RenderPlayer , i guess. Then somehow check that you are rendering your steve's model.
