HI! It seems like a great idea to make a mod for Minecraft that adds wearable hearing aids for deaf gamers. It is very important for everyone to enjoy video games, and this mod could help deaf gamers have a more immersive experience.
Adding a whistling sound when wearing hearing aids could be very helpful in signaling to players that the mod has been successfully activated. It's a simple but effective idea. Also, the slight resistance to the body could add another layer of realism to the gaming experience.
I'm sure the deaf gamer community will really like this mod. It may also attract the attention of other game developers who may be inspired to create accessible content for gamers with disabilities.
As a developer, there are many resources available online to help you create this mod. You may also want to contact other Minecraft mod developers for tips and advice on how to get started.
I hope this mod becomes a great success and many deaf gamers can enjoy Minecraft more fully thanks to your work.
