I have two mods that have working Sound Events.  I have encountered a situation where I would like to be able to define a custom Sound Type, as the available SoundTypes don't fit the block I have created.  I have not been able to find a post or example so far to know if I'm missing a requirement.

 

I have confirmed that the sound file itself works with OnBlockPlaced, so the sound file and the sounds.json file are fine.

 

When I define a Custom SoundType, the vanilla action sounds work without issues.  The custom action sound causes a null pointer exception.  The log itself hasn't helped in identifying a cause.

 

Eclipse shows the correct path, so it isn't an issue of not finding the sound file/file not found exception.

 

Block Class:

setSoundType(TyrDropSounds.COINS);

 

Sounds Class:

public static SoundEvent coins_sliding;

 

coins_sliding = registerSound("coins_sliding");

 

public static SoundType COINS = new SoundType(1.0F, 1.0F, coins_sliding, SoundEvents.BLOCK_WOOD_STEP, SoundEvents.BLOCK_WOOD_PLACE, SoundEvents.BLOCK_WOOD_HIT, SoundEvents.BLOCK_WOOD_FALL);

 

 

I'm wondering if there is something else that must be done for Custom SoundTypes or other information that may make this problematic, since I think the available sounds work for the vast majority of blocks.  Chains and Coins are my only two use cases so far.  Thanks for any info.

 

 

If it is a NullPointerException something is null and it is your job to find it.

If you can't figure it out yourself, post the crash log.

I do know that if I substitute a vanilla sound in for the custom sound, it does not crash.  Sorry if that was not clear earlier.  I have also tried other working custom sounds, and they cause a crash as well when used.

 

public static SoundType COINS = new SoundType(1.0F, 1.0F, coins_sliding, SoundEvents.BLOCK_WOOD_STEP, SoundEvents.BLOCK_WOOD_PLACE, SoundEvents.BLOCK_WOOD_HIT, SoundEvents.BLOCK_WOOD_FALL);

 

At one point I thought that SoundTypes needed to be registered like SoundEvents, but I don't believe that is the case.  If they did, then I would not expect the vanilla sounds to work in the statement above, nor have I found where they are registered like SoundEvents.

 

Minecraft 1.10.2, Forge 12.18.1.2011

 

Thanks for any insights.  I spent a large chunk of Sunday trying to identify my mistake or lack of understanding.
