Siren Head V4 Clean Code Rewrite

Siren Head V4 Clean Code Rewrite is a fixed and improved version of the Siren Head add-on for Minecraft Bedrock.

This version keeps the original models, textures, sounds, and animations, but the script and command logic were rewritten and cleaned up. The main goal of this version is to fix AI problems, improve compatibility with newer Minecraft Bedrock versions, and make Siren Head work more smoothly.

    Hey, I played with this mod today and it triggered the siren head grabbing players and throwing them to their deaths - that was absolutely awesome! I'm really looking forward to seeing more interesting behaviors from the siren head. Thanks

    Soooo I See You Used Some Things From My Fixed Version
    Example 1 The Revolver Is Almost The Same As The One I Made/Fixed

    Example 2 The Siren Head Head Block Is Also Made In MY Coding Style Using Format Version 1.21.10

    I need Some Kind Of Info As of why you didnt Include me in the credits for SOME of The Code Parts bc I knew what i was doing when i fixed it

    Also The Moring Escape Off Function Does Not Even Work When i Have The Daylight Set To "always day"

    I Need Some Info

      Hey, sorry about that. I didn’t mean to steal your work or leave you out of the credits.

      I fixed and edited the addon, but if some parts like the revolver, the Siren Head head block, or code parts are from your fixed version, I will add you to the credits properly.

      Please tell me exactly what parts are yours and what name/link you want me to credit, and I’ll update the description.

      Also, if you want, I can fully rewrite those parts of the code from scratch so they are not based on your version.

      I’ll also check the Morning Escape function. If it doesn’t work correctly, I’ll fix it or remove it from the description.

      Thanks for telling me.
      Im so sorry

      Hey, I understand. For the newest version, I rewrote the script/code parts from scratch, including the AI fixes, attack freeze fix, and spawn mode commands. I’m not trying to use or steal your fixed version.

      If any specific part still looks too close to your version, tell me exactly which file or feature and I can rewrite/change it again.

    Honestly, I was so desperate for this Siren Head addon to be updated by the original creator Bendy, but it seems like he has left it in the dust (idk if his coming back to fix himself but likely not). I'm glad someone came to fix it. But I know well it's gonna be hard to make this version Achievement Friendly

        Also there are add-ons that are the fixed version v4,that are similar to this one, without the book and the Morning Escape,(which is a function where Siren Head flees if it is daytime and despawns),you can find one on Youtube by clicking the link on the description.(make sure that it is not a virus tho)

        Is it a item tho?Also,rename the addon because it can be confused with the Siren Head addon v4.1 Remake by AbsoluteDimension2468 which is very similar.
