Corrupt ender

Corrupt Ender adds a corrupt ender eye and a sturdier, purple-tinted end portal frame that you can collect and reuse.

• Craft the Corrupt Ender Eye with an Eye of Ender in the center, obsidian on the cardinals, and amethyst shards on the corners. It still locates strongholds when thrown.
• Using a Corrupt Eye on vanilla end portal frames inserts the eye and lights the portal as normal. If that lit portal includes any corrupt eyes, a 5-second timer starts; when it ends, only the frames with corrupt eyes pop off, dropping Corrupt End Portal Frames. The portal blocks are cleared and subtle purple particles appear.
• Corrupt End Portal Frames are blast-resistant, fireproof items that always drop and require a diamond-tier pickaxe. They look like the vanilla frame but with purple in place of green.
• Build a portal with Corrupt Frames in the standard 3x3 ring and fill them with normal Eyes of Ender to form a stable portal (no timed collapse). Vanilla eyes can also fill them directly.

Implementation notes:

• The mod runs as a dedicated-server mod (@Mod dist is DEDICATED_SERVER) and tracks corrupt eye placements via saved data so collapse timers survive reloads.
• Portal collapse scheduling checks for active end portal blocks with corrupt eyes and closes only those frames, leaving normal frames in place.
• Assets include purple frame textures and a purple/red corrupt eye icon; creative tabs list the new block under Functional Blocks and the eye under Ingredients.

Known limitations and tips:

• Clients need this mod (and assets) to see the custom frame and eye correctly.
• If the portal is broken before the timer ends, the collapse is cancelled until the portal is relit with corrupt eyes.***
